Methodology

We tracked the largest announced rounds in the SA国际传媒 database that were raised by U.S.-based companies for the period of April 18-24. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

Illustration:

On the positive side, EVs are gaining ground. In 2025, sales increased by more than 20% year on year, rising to 21 million units, per .

On the other hand, early EV optimists assumed we鈥檇 be much further along by now. And while sales are up, the is slowing, driven by affordability constraints, trade friction and shifting government incentives.

The broad trend: Funding to EV-related startups reflects a similar mix of optimism and restraint. Investors are backing big rounds for a handful of upstart brands like customizable pickup truck maker and micromobility spin-out . Yet funding remains far below prior peaks and exit activity appears muted.

The numbers: Companies in SA国际传媒鈥檚 electric vehicle category are on track to see higher investment this year relative to last. Around $3.6 billion has gone to companies in the space so far in 2026, spread across about 50 rounds.

However, we鈥檙e still nowhere near the 2021 cyclical peak, when nearly $19 billion went to global EV startups. For perspective, we charted investment and deal count since 2020 below.

Noteworthy deals

The largest round tied to the EV space this year went to , which isn鈥檛 an electric vehicle brand but rather a developer of autonomous driving technology that has been tested on EVs. The London-based company raised $1.2 billion in a February financing at an $8.6 billion valuation.

Another standout fundraiser was Troy, Michigan-based Slate Auto, a developer of lower-cost electric pickup trucks that can be customized as SUVs. The -backed company raised $650 million in Series C funding last week and says it plans to deliver its first vehicles to customers later this year.

The Rivian spin-out Also, focused on electric bikes and skinny four-wheeled models capable of carrying cargo, is also scaling up, securing $200 million in Series C funding in March. The startup also plans to partner with to develop autonomous delivery vehicles.

China-based startups are also scaling up. , a developer of autonomous electric trucks,听 secured $310 million early this year, while , the flying car subsidiary of EV brand , picked up $200 million in fresh financing.

Exits

While private funding still flows to EV-related startups, exit activity has been comparatively slow.

On the IPO front, Chinese EV car brand made its Hong Kong debut last month. And India-based electric scooter and charging provider went public last spring.

U.S. startups, however, have been sitting out the IPO market in recent quarters, with the exception of a $9 million micro- early this year from solar electric vehicle brand .

As for M&A, we haven鈥檛 seen sizable disclosed-price purchases of private, venture-backed EV companies in recent quarters, per SA国际传媒 data. Another deal in the wings, meanwhile, is a planned SPAC merger transaction involving Swedish autonomous electric freight shipping startup .

Outlook

The EV funding environment, neither especially weak nor particularly robust, contrasts sharply with the investment climate for autonomous driving startups, which hit a record amount this year. Perhaps, over time, we鈥檒l see some momentum spilling over to EVs, as you can鈥檛 have autonomous vehicles technology become widespread without somebody supplying the actual vehicles.

Methodology

The SA国际传媒 Unicorn Board is a curated list that includes private unicorn companies with post-money valuations of $1 billion or more and is based on SA国际传媒 data. New companies are as they reach the $1 billion valuation mark as part of a funding round.

The unicorn board does not reflect internal company valuations 鈥� such as those set via a 409a process for employee stock options 鈥� as these differ from, and are more likely to be lower than, a priced funding round. We also do not adjust valuations based on investor writedowns, which change quarterly, as different investors will not value the same company consistently within the same quarter.

Funding to unicorn companies includes all private financings to companies that are tagged as unicorns, as well as those that have since graduated to .

Exits analyzed here only include the first time a company exits.

Please note that all funding values are given in U.S. dollars unless otherwise noted. SA国际传媒 converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to SA国际传媒 long after the event was announced, foreign currency transactions are converted at the historic spot price.

Methodology

We tracked the largest announced rounds in the SA国际传媒 database that were raised by U.S.-based companies for the period of April 11-17. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

Several multibillion-dollar megadeals drove the spike in first-quarter investment. That signals investors aren’t just paying for research anymore, but betting on companies that are ready to scale up and put their AI technology into actual cars people can buy or hail.

So far in 2026, we鈥檝e seen a shift to a small number of autonomous vehicle companies capturing a disproportionate share of global capital, with a handful of giants, including ,听 and , getting the lion鈥檚 share of funding.

The broad trend: It appears that investors are no longer spreading small bets across dozens of startups. Instead, they are pouring billions into the three or four players they believe will own the market. And while North America remains the largest hub for overall funding volume, the Asia-Pacific region 鈥� specifically China 鈥� is seeing the fastest growth in deployment. Chinese startups are also raising some of the largest rounds in the space.

The numbers: Autonomous vehicle startups raised a record $21.4 billion across 34 deals through April 15, . That鈥檚 up a staggering 262.17% compared to the $5.9 billion raised across 99 investments globally in all of 2025. It鈥檚 also about 77% higher than the $12.1 billion raised across 127 deals in 2024.

Noteworthy deals

Exactly three-fourths of the $21.4 billion raised in 2026 thus far is attributable to Mountain View, California-based Waymo鈥檚 raised in February. , , and co-led the financing, which was raised at a staggering $126 billion valuation.

But it wasn鈥檛 the only outsized round.

San Diego-based Shield AI landed a $2 billion Series G round co-led by and . Its valuation jumped to $12.7 billion.

And London-based Wayve raised a $1.3 billion Series D round co-led by , and , achieving an $8.6 billion valuation.

Interestingly in 2025, three of the four largest autonomous vehicle rounds were raised by Chinese companies: an $897.7 million Series C by ; a $600 million Series D by , and $527.8 million by .

IPO outlook

We didn鈥檛 see any IPOs in the space in 2025, but some are on the horizon for this year.

Beijing-based confidentially in March. Backed by , and , it is seeking a valuation above $14 billion.

secured $24.7 million in pre-IPO funding in March and is as it expands its AI-led logistics projects.

Because Waymo is a subsidiary of Alphabet (), it doesn’t need to go public for cash, but industry observers are increasingly discussing a potential spinoff. With a $126 billion valuation, it would instantly become one of the most valuable transportation companies in the world if it hit the public market.

In fact, SA国际传媒 data shows the extent to which venture funding this year has been a case of more capital concentrated into a select few companies and a single industry. Last quarter, a handful of large, well-funded AI companies, almost all based in the U.S., captured the vast majority of venture dollars, even as global startup deal count fell.

AI takes 80% of global venture funding

AI startups for the first time captured half of global venture funding in Q4 2024. Since then, that percentage has hovered around 50% 鈥� until Q1 of this year, when 鈥檚 record-setting round, along with a small handful of other enormous deals, pushed AI鈥檚 share to 80% of the quarterly funding total.

Top 4 vs. everyone else

It wasn鈥檛 just that AI as an industry captured the lion鈥檚 share of venture funding last quarter. Just four companies took nearly two-thirds of the entire pie, SA国际传媒 data shows.

Four of the five largest venture rounds ever recorded were closed in Q1 2026, with frontier labs OpenAI ($122 billion), ($30 billion), ($20 billion) and self-driving company ($16 billion) collectively raising $188 billion, or nearly 65% of global venture investment in the quarter.

Deal count falls even as dollars surge

And while last quarter set an all-time record for venture dollars invested, more money went to fewer companies, continuing an overall downward trend for deal count we鈥檝e seen since the beginning of 2021.

That was the case not just in North America, where dollars invested surged 190% year over year, even as deal count dropped 26%. It also held true in Europe and Latin America. Only Asia saw a modest 5% bump in deal count along with more dollars invested.

Still, Europe saw more capital going into fewer companies in Q1, with deal volume plummeting 40% year over year. Much of the decline was at seed stage (down 44%) and early stage (down 30%), while late-stage deal volume was in-line with the previous four quarters.

AI above 50%

Funding to Europe-based AI startups increased significantly last quarter, reaching $9.2 billion, or more than half of total venture funding to the region. That marks the sector鈥檚 highest proportion in a quarter on record.

The largest four rounds to startups based in Europe in Q1 were for AI-related companies. Data center builder , autonomous driving developer , and frontier lab for physical AI raised more than a billion each, and AI legaltech 鈥檚 funding totaled more than $500 million.

UK and France grew YoY

Startups from the U.K. and France raised more funding in Q1, totaling $7.4 billion and聽 $2.9 billion, respectively. Germany-based startups raised $1.9 billion, flat year over year.

France has emerged as the European leader for AI frontier labs. Last quarter, it saw Paris-based , founded by former AI chief , raise $1 billion in the continent鈥檚 largest seed funding round on record. The deal also marked only the second billion-dollar-plus funding deal for a European frontier lab, following s $2 billion round last year.

Europe by stage

In Q1, late-stage funding to Europe-based startups nearly doubled from a year ago. The largest rounds were across a variety of sectors, including AI hardware, fintech, agentic AI, productivity software, sensors, defense, e-commerce and energy.

A total of $9.2 billion was invested at late-stage across 83 deals, up 91% by amounts year over year.

Early-stage funding to the region鈥檚 startups fell from a year earlier 鈥� by around 20% 鈥� SA国际传媒 data shows. Early-stage investment totaled $5.3 billion in Q1 across more than 240 funding rounds. Within early-stage funding, larger Series A rounds predominated in semiconductors, energy and healthcare.

Seed funding reached $3.1 billion in Q1 across more than 790 deals. The funding total was up 50% year over year, but largely due to the $1 billion round for Advanced Machine Intelligence.

In summary

Larger rounds into critical sectors in AI drove European startup funding up in Q1. A mix of Europe- and U.S.-based investors led the largest fundings last quarter into AI infrastructure, frontier labs, autonomous systems and applications.

Overall, Europe is in-line with global trends as capital concentrates into the largest deals in sectors that are surging due to AI.

Methodology

We tracked the largest announced rounds in the SA国际传媒 database that were raised by U.S.-based companies for the period of April 4-10. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

Illustration:

In a quarter when nearly two-thirds of global venture capital went to just four companies, it鈥檚 easy to lose track of the many other companies getting funding to tackle interesting problems. Nonetheless, we spotted five companies in just the past month working on issues from cleaner ferries and trains to foundational AI for plants. Let鈥檚 take a closer look.

$55M for a mineral rights-backed credit card

Natural resources can be incredibly valuable financial assets, but you can鈥檛 exactly buy your weekly groceries with oil or water rights.

That鈥檚 an issue that a Dallas-based fintech startup aims to solve. recently raised $50 million in a debt round from to provide a credit card to U.S. households holding mineral rights to natural resources such as oil, natural gas, solar, wind or water.

鈥淔or the millions of mineral rights owners in the United States, these rights are one of the most valuable assets the family owns. But these families are just like the rest of Americans and often are carrying revolving credit card balances at more than 25% [interest],鈥� Frontlands CEO said in a statement. 鈥淗istorically, owners have had few options to access the value trapped inside their mineral rights without selling.鈥�

Its AI system combines machine learning, production data, royalty payment histories, lease terms, commodity price forecasts, geologic data and traditional to automate the underwriting process, the company says. While it鈥檚 historically been difficult for traditional lenders to assess natural resources as collateral, Frontlands says its process typically delivers a same-day credit decision.

The company鈥檚 recent credit facility is in addition to a announced in December from venture investors including , , and .

Frontlands said its average credit line in early markets 鈥� Texas, Pennsylvania, New Mexico, North Dakota, Wyoming and Oklahoma 鈥� is more than $30,000. It plans to launch its credit card product this summer in partnership with Texas-based sponsor bank .

Frontlands said it also expects to raise a Series A round later this year.

鈥淥ur goal isn鈥檛 to pile on more debt,鈥� Cotter said in a statement. 鈥淏ut the opportunity to help our customers move away from high-interest credit card debt 鈥� and provide a path toward greater financial stability 鈥� is compelling.鈥�

Investment in fintech startups hit a multiyear high in 2025, SA国际传媒 data shows, though remains well below the peak. Many of the best-funded companies in recent quarters have brought AI to bear on traditionally more manual or cumbersome processes in the financial services industry.

$32M for 鈥榝lying鈥� electric commuter ferries

As of this writing, oil prices are hovering around $100 a barrel 鈥� down from an even greater peak a few weeks earlier, but still among the highest levels seen in years, as the U.S.-Iran war disrupts global energy markets.

So Swedish electric vessel maker 鈥檚 recent funding of 鈧�30 million (about $32 million) seems timely. The Stockholm-based company makes electric 鈥渇lying鈥� boats that are used as commuter ferries. They differ from traditional vessels by using computer-controlled hydrofoils to lift the hull above the water, an approach the company says dramatically reduces drag and cuts energy use by up to 80% 鈥� enabling faster, smoother, zero-emission travel compared to conventional diesel ferries that push through the water.

鈥淔rom a physics perspective, ships have been essentially the same for hundreds of years,鈥� Candela founder and CEO said in a statement. 鈥淲e’re redefining waterborne transport by effectively creating a new category of vessel. This allows cities and municipalities to finally take full advantage of waterways 鈥� while escaping the fossil-fuel cost trap that has long prevented them from being used efficiently.鈥�

Its P-12 vessels have already been deployed as commuter ferries in Stockholm, Gothenburg, Oslo and Trondheim.

The new funding was led by 鈥檚 arm and included previous investors , , and .

The capital will primarily be used to fund a second factory in Poland. Candela says it has more than 65 vessels on order and planned deployments across markets including India 鈥� where a fleet of 10 of its P-12s will reportedly cut travel times from Navi Mumbai Airport to the city center from around two hours to 35 minutes 鈥斅爐he Middle East and Southeast Asia.

The startup鈥檚 funding defies an overall downturn in clean-tech funding. Funding for clean-tech related startups totaled $26.9 billion in 2025, down 23% year over year and the lowest annual amount since 2020, SA国际传媒 data shows.

$30M to electrify trains with batteries and microgrids

Let鈥檚 now turn from waterways to train tracks, with another company that recently raised significant funding aimed at giving centuries-old transportation systems a green overhaul.

, a Philadelphia-based startup, said last month that it raised $30 million in seed funding led by Australian mining company and Israeli venture firm to develop a new way of powering freight rail that avoids the high costs of traditional electrification.

The startup positions its technology as a way to decarbonize one of the world鈥檚 most efficient but still fossil-fuel-dependent transport systems. It鈥檚 targeting a major pain point for the rail industry: its heavy reliance on diesel. In North America alone, the six largest freight rail operators spend roughly $11 billion annually on diesel fuel, while full electrification of rail networks could cost more than $1 trillion, according to Voltify.

Instead of relying on overhead wires, Voltify says it鈥檚 building a system that combines battery-equipped railcars with technology that allows trains to recharge while moving. The goal is to help rail operators cut emissions and fuel costs without requiring massive infrastructure overhauls.

Its approach 鈥� using mobile batteries and distributed charging via microgrids 鈥� aims to sidestep those costs by retrofitting existing trains and building localized energy systems rather than rebuilding entire rail networks.

CEO and co-founder that the company has signed a paid pilot agreement with a Class 1 railroad, though she declined to name the customer, citing a confidentiality agreement.

She noted in a that raising funding for a transportation company in the current market was difficult. 鈥淪ecuring capital in the hardware space and traditional industries is challenging,鈥� she wrote. 鈥淚t is not the 鈥榠n鈥� space; there is no FOMO at play, so we need to focus on metrics and execute quickly. With some of the top 5 largest rail companies globally and a large order pipeline, we are determined to keep moving at lightning speed.鈥�

$7M for foundation AI for biology

Funding to foundational model AI startups surged last quarter, reaching $178 billion, per SA国际传媒 data. But the vast majority of that funding went to AI giants like and that are building general-purpose GenAI models.

Such models are fundamentally lacking for hard sciences, argues , a startup based in Paris and Berkeley, California, that last month raised $7 million in seed funding to develop foundation AI for biology trained on DNA, RNA and data from other 鈥溾�� fields, rather than human text.

The company鈥檚 first family of transformer models is called Botanic and is trained on data from 43 plant species. Living Models noted that it鈥檚 starting with the commercial crop industry, a massive global market that has abundant data, well-established research infrastructure, and fewer regulatory concerns and faster commercialization timelines than the pharmaceutical industry.

鈥淧lant biology combines three properties that make it an ideal first domain for biological foundation models: genomic data is abundant and largely unrestricted, the commercial need is acute and quantifiable, and the feedback loop between computational prediction and real-world validation is well established through existing breeding infrastructure,鈥� the company said in a statement.

The global seed industry is also dominated by a handful of incumbents, it noted: , , , and 鈥斅燾ompanies that already spend billions of dollars a year on breeding research.

鈥淏iology is an information problem at every scale, from a single cell to an entire ecosystem. The genomic data exists across many domains; what’s been missing is a model architecture capable of learning from it at scale,鈥� , Living Models鈥� CTO and co-founder, said in a statement. 鈥淲e start with plants because the data is rich and the breeding cycle is a clear bottleneck, but the same approach applies wherever sequence data meets slow, empirical discovery.鈥�

$2.1M for a brain-stimulating consumer wearable

Billions of dollars a year are spent on therapy and other mental-health treatments, yet measuring progress can be elusive.

That鈥檚 one of the issues that San Francisco-based aims to take on with a neuromodulation wearable headset that it says can reduce stress, improve attention span and mood, and more quantitatively measure mental health scores.

Mave鈥檚 device uses transcranial direct current stimulation, or tDCS, a noninvasive technique that delivers a low electrical current to the brain through electrodes placed on the scalp, with the aim of modulating neural activity. The technology is when used by adults as directed in controlled settings.

The company last month raised $2.1 million in seed funding led by , with participation from individual investors including Autopilot AI lead .

Crucially, Mave says it does not plan to pursue medical-device approval for its product, which sells for $495. Instead, it is positioning the gadget as a wellness tool that consumers can use on a daily basis to improve their mental well-being and better measure the outcomes of talk therapy or other treatments.

鈥淚f you ask a psychologist how do you know if a person is making progress, their response to it is very standard, which is that it鈥檚 not about progress. It鈥檚 about process [鈥 But for somebody with depression who is spending a lot of time in therapy, progress is important. So how do you know whether they鈥檙e making progress or not?

U.S. and Canadian companies secured a staggering $252.6 billion in seed- through growth-stage funding rounds per SA国际传媒 data. That鈥檚 more than 3x the total raised in the prior quarter, and the largest quarterly total of all time.

Predictably, artificial intelligence was the driver. More than 87% of Q1 investment went to companies in SA国际传媒 AI-related categories.

To say these are record funding tallies is somewhat of an understatement. It鈥檚 more like Q1 smashed the prior quarterly record 鈥� $95.7 billion 鈥� set in Q3 2021.

Just a single financing for was bigger than the prior quarterly record for all startup funding rounds put together. And the four next-largest financings totaled almost as much as the prior quarter, which at the time we considered a very strong period for startup funding.

So, in summary, it was a lot of money. For a more detailed picture, we drill down more deeply into how that largesse was distributed across stages and sectors. We also take a look at exits for the quarter, including both IPOs and acquisitions.

AI

We鈥檒l start with AI, since that鈥檚 where the overwhelming majority of the money went.

A staggering $221 billion went to North American companies in SA国际传媒 AI-related categories in the first quarter. That鈥檚 about 6x the AI investment total from the prior quarter, which was itself no slacker on this front.

For perspective, we charted out AI-related funding over the past 13 quarters to compare.

A few megarounds for high-profile companies accounted for most of the quarter鈥檚 AI funding, led by OpenAI, , and .

Later stage and technology growth

These same names factor heavily in tallies for late-stage and technology-growth funding, which comprised the vast majority of total startup investment.

Per SA国际传媒 data, $222.4 billion 鈥� or 88% of all North America startup investment 鈥� went to rounds at these stages. That鈥檚 more than 5x the prior quarter鈥檚 tally, and more than triple year-ago levels.

The gains were driven by bigger deals, not more of them. Later- and growth-stage round counts were actually down a smidge sequentially in Q1. For perspective, below we chart round counts and investment totals at this stage for the past five quarters.

Enormous rounds for AI companies accounted for a majority of the late- and growth-stage totals. The biggest of these was OpenAI鈥檚 record-setting $110 billion February financing led by , and . The generative AI giant topped it off with a raise in March.

Anthropic secured the quarter鈥檚 next-biggest late-stage financing 鈥� a $30 billion February Series G 鈥� followed by xAI, which announced a $20 billion Series E in January. landed another of the quarter鈥檚 very big deals, with a $16 billion February Series D.

Early stage

Early-stage investment was also running high in Q1, albeit not setting records.

Overall, investors put $25.1 billion into deals around Series A and Series B stage in the first quarter. That鈥檚 up 17% from the prior quarter and 56% from year-ago levels. It鈥檚 also the highest quarterly total in over three years, though still below peaks scaled in 2021.

Early-stage round counts, meanwhile, were down a bit, indicating investors鈥� increasingly concentrating their bets among perceived star performers.

As usual, a few jumbo-sized deals significantly boosted the early-stage totals. For Q1, this included four rounds of $500 million or more.

Of these, Austin-based humanoid robotics startup was the biggest fundraiser, pulling in $520 million in a February Series A. Three other companies secured $500 million financings: AI infrastructure developer , semiconductor startup , and industrial robotics-focused .

Seed

Seed-stage investment, meanwhile, did not show an upswing but remained at historically robust levels.

Per SA国际传媒 data, an estimated $5.1 billion went to seed and pre-seed investments in Q1. That鈥檚 roughly flat with the prior quarter and up a bit from year-ago levels.

Seed round counts declined in Q1, both sequentially and year over year. However, we expect these tallies to rise some over time, along with investment totals, as seed deals commonly get added to the data set weeks after they close.

Exits

Exit activity was fairly staid in comparison to the high-rolling startup fundraising environment.

That said, the IPO market did boast a few sizable startup debuts. Of these, the largest was the January IPO of construction equipment rental marketplace , followed by space tech company , and crypto platform .

Below, we aggregated a list of 12 private, venture-backed companies that carried out IPOs on U.S. exchanges.

Acquirers also announced several large deals to purchase venture-backed private companies.

The priciest planned M&A deal was 鈥檚 agreement to purchase business credit card provider for $5.15 billion. Biotech also delivered some large outcomes, including 鈥檚 planned acquisition of RNA therapeutics startup , and 鈥� purchase of allergy treatment startup .

Below, we put together a list of five of the quarter鈥檚 biggest M&A deals.1

Big picture: A paradigm shift

Having written many of these funding reports over the years, it鈥檚 common for one quarter to quietly blur into another. Not so for Q1 of 2026.

The just-ended quarter cemented a notion that startup insiders have been circling for some time: Private markets now have the capital stores and appetite for ultra-high valuations to rival public markets. For evidence, look no further than OpenAI鈥檚 $122 billion raise at a valuation higher than all but a handful of the largest large-cap technology companies.

IPO enthusiasts may pine for a future period when these most sought-after foundational AI names finally do make it to public markets. But for now, they鈥檝e demonstrated there are plenty of investors willing to shell out billions in private offerings as well.
