AI Startup Funding 2023–2026: Global Deal Database | NEXAIRI

How Big Did AI Funding Get Between 2023 and 2026?

Global private AI funding crossed $100B for the first time in 2024 and then nearly doubled the following year, reaching $225.8B in 2025.

That scale is hard to contextualize without a baseline. Goldman Sachs economists Joseph Briggs and Devesh Kodnani published a forecast in August 2023 estimating that total global AI-related investment would approach $200 billion by 2025 — combining hardware, software, and services. The actual venture-only total came in above that prediction for 2025 alone, before counting infrastructure capex from hyperscalers.

The period from 2023 to early 2026 marks a distinct phase: the transition from AI as a speculative category to AI as the primary destination for serious private capital. By the end of 2024, CB Insights reported that AI captured 37% of all global venture funding and 17% of all deals — both all-time highs up to that point. By 2025, those figures climbed further, with LLM developers alone drawing 41% of total AI investment.

The table below summarizes annual AI funding totals and deal counts across the full period covered in this database, drawing on CB Insights annual reports for 2023, 2024, and 2025.

Two patterns are visible in the data. First, the total keeps compounding at a pace few analysts predicted even 18 months ago. Second, the concentration of money narrows as totals rise. Mega-rounds drove an increasing share of each successive year's total — from roughly 55% in 2023 to 79% in 2025 — meaning the growth isn't uniformly distributed across startups. It's pooling in a small number of large bets.

What Does 'Scope' Mean for This Database?

This database covers disclosed AI equity funding rounds of $1M or more from January 2023 through Q1 2026, drawn from CB Insights, Goldman Sachs Research, and public coverage.

The data in this article draws on publicly reported equity funding rounds for private or recently private AI-related startups from January 2023 through Q1 2026, skewing toward rounds of $1M or larger.

The primary aggregated sources are: CB Insights State of AI reports for 2023, 2024, and 2025; CB Insights State of Venture reports for 2023 and 2024; Goldman Sachs Research publications on AI investment; and publicly reported individual funding announcements via Crunchbase and TechCrunch coverage.

Readers should note that "AI-related" funding definitions vary by tracker. CB Insights classifies companies as AI if AI is central to their product or business model — not just if they mention AI in press materials. The figures cited throughout this article use that narrower CB Insights definition unless otherwise noted.

The scope also excludes most infrastructure capex: the hundreds of billions Microsoft, Google, Meta, and Amazon committed to AI data centers between 2023 and 2026 are not venture rounds and don't appear in startup-focused totals. The figures here cover private company equity deals.

How Did AI Funding Break Down by Sector?

LLM developers dominated dollar volume, while robotics led by deal count, and digital health and fintech lost ground as AI infrastructure absorbed a growing share.

CB Insights data for 2025 shows robotics hardware and software companies captured the largest share of AI deals at 11.4%. Digital health came in second at 8.3%, down from 12.9% in 2021. Fintech took 6.5%, down from 9.7% in 2021. The trend across sector-specific AI is consistent: vertical applications are getting a smaller slice of a much larger pie.

On the dollar side, the story is different. Three foundation model companies — OpenAI, Anthropic, and xAI — raised a combined $86.3B in 2025 alone. That's 38% of the year's entire AI venture total, according to CB Insights. In Q4 2025, those three companies raised $46B — over half of that single quarter's funding.

One notable shift is the rise of defense-related AI companies. Helsing (Germany), Anduril (US), and Saronic (US) all appeared in CB Insights' top-round list for 2025. This is a sector that barely registered in 2022 AI funding trackers. The Ukraine conflict and various geopolitical pressures appear to have accelerated government and VC interest in dual-use AI applications.

How Much AI Funding Went to US-Based Startups?

US startups captured 76% of global AI dollars in 2024 while producing only 49% of deals — meaning American raises are dramatically larger than international counterparts, per CB Insights.

In 2024, US-based AI companies took in 76% of global AI venture dollars — but only 49% of deal volume, according to CB Insights. That gap tells the most important story about American AI funding.

The US dominance in dollar share reflects the location of the largest foundation model labs: OpenAI (San Francisco), Anthropic (San Francisco), and xAI (Austin, and incorporated in Texas). These three companies together raised $86.3B in 2025 — amounts that simply don't have counterparts in other regions yet.

Goldman Sachs' August 2023 research note, authored by Briggs and Kodnani, anticipated this: "The U.S. is positioned as the market leader in AI technology, and American companies will likely be relatively early adopters." Their projection that AI investment could approach $100B in the US alone proved directionally accurate — the US likely received somewhere between $75B and $100B of 2024's $100.4B AI total, based on CB Insights' 76% share disclosure.

At the city level, San Francisco and the broader Bay Area dominate deal origination for foundation models and developer tools. New York and Seattle also contribute, particularly in enterprise AI applications. Austin has grown as xAI recruited there. Boston carries weight in biotech-AI via companies like Abridge.

What's Happening With AI Funding in Europe?

Europe's AI funding scene is more active than headlines suggest — but the capital is smaller in check size and concentrated at early stages, according to CB Insights 2024 data.

European startups accounted for 22.9% of global AI deal volume in 2024, nearly matching Asia's 23.2%. But the dollar share is much smaller. Europe-based AI companies are receiving mostly seed and Series A capital: 81% of European AI deals in 2024 were early-stage — a seven-year high for that metric, per CB Insights.

CB Insights' 2024 State of AI report highlighted that European countries dominate the top-10 list of countries by median Mosaic health score for AI startups outside the US. Israel leads with a median score of 700, while UK, Germany, and France show strong pipelines.

The M&A data tells a similar story. UK-based AI startups led European M&A in 2024 with 32 acquisition deals. Germany had 18, France 16, and Israel 12, per CB Insights. This is notable: European startups are increasingly being acquired rather than scaling to late-stage funding rounds, partly reflecting the difficulty of accessing growth-stage capital in the region.

Specific large European AI rounds in 2023–2025 include Helsing (German defense AI, co-founded by Gundbert Scherf and Niklas Köhler), which raised around $600M across two major rounds. France's Mistral AI raised a €600M Series B at a €6B valuation in June 2024. These are the leading edge of what remains a mostly early-stage ecosystem by deal volume.

How Did India and Asia-Pacific Fare in the AI Funding Race?

India, Japan, and South Korea all posted modest year-over-year deal growth in 2024 — bucking the global decline — while China saw a sharp fall as investors redirected capital.

The Asia-Pacific region as a whole accounted for 23.2% of global AI deal volume in 2024, nearly matching Europe, per CB Insights. But the composition differs sharply by country.

China saw its deal count fall 33% year-over-year in 2024 — the steepest drop among any major dealmaking country tracked by CB Insights. This likely reflects a combination of geopolitical risk perception from Western investors, US export controls on advanced chips, and a pullback by Chinese domestic investors. DeepSeek's high-efficiency open-source models continue to draw attention but are largely state-adjacent rather than VC-funded in the traditional sense.

India posted a +1% deal gain in 2024. Japan gained +2%, and South Korea +1%. CB Insights attributes their relative resilience partly to investors diverting funds away from China. India in particular has a growing pipeline of applied AI companies targeting domestic enterprise and BPO workflows.

In Southeast Asia, the picture is more fragmented, with Singapore serving as the primary hub for AI-focused VC activity in the region. Standalone data on Southeast Asia-specific AI rounds from the 2023–2026 period is not broken out in CB Insights' public summaries, but Singapore's tech ecosystem has reported a series of seed-to-Series A AI investments in fintech and logistics AI from firms like Sequoia Capital Southeast Asia.

Which Investors Led the Most AI Deals?

Corporate venture capital from big tech dominated AI investment activity in Q4 2024, while traditional VC firms continue backing early stages at high volume globally.

CB Insights' State of AI 2024 report identified Google (GV), Nvidia (NVentures), Qualcomm (Qualcomm Ventures), and Microsoft (M12) as the most active corporate investors in AI by number of companies backed in Q4 2024. These firms aren't just providing capital — they're offering cloud credits, chip access, and distribution partnerships that are often more valuable to early-stage AI startups than the funding itself.

On the traditional VC side, Andreessen Horowitz (a16z) has been among the most publicly vocal, producing regular AI deal announcements and publishing research through its website. Sequoia Capital has backed multiple top-performing AI companies including OpenAI (early stage). Khosla Ventures participated in a $6.6B OpenAI round. Spark Capital backed Anthropic. These names recur across the largest foundation model rounds disclosed between 2023 and 2025.

For M&A specifically, Salesforce was the most active acquirer of AI startups in 2025 with 10 acquisitions, per CB Insights — including Spindle (agent analytics), Qualified (marketing automation), and Doti (agentic enterprise search). Workday, Meta, and CoreWeave each made four acquisitions.

What Were the Biggest Individual AI Funding Rounds?

The largest AI rounds between 2023 and 2026 went to US foundation model labs, with xAI's $20B Series E in January 2026 topping a list dominated by OpenAI, Anthropic, and Databricks.

The five largest AI deals of 2024 all went to US-based model and infrastructure companies — and 2025 broke those records again, with xAI raising $20B in a single Series E.

In 2024, Databricks led with a $10B Series J. OpenAI raised $6.6B. xAI closed two separate $6B rounds. Anthropic closed a $4B round. That accounts for five of the year's thirteen billion-dollar-plus deals. CB Insights confirmed that four of the top five 2024 rounds closed in Q4 alone, contributing to a 53% quarter-over-quarter spike in total funding in that quarter.

In 2025, the scale escalated. OpenAI, Anthropic, and xAI combined for $86.3B in a single year. In January 2026, xAI raised a $20B Series E (with $7.5B in equity), and Anthropic announced it would raise another $10B that same week. CB Insights confirmed both announcements in its January 2026 reporting.

Notable rounds outside the US include Wayve, a UK-based autonomous driving company that raised $1.05B in May 2024 in a round led by SoftBank, Microsoft, and NVIDIA — one of the largest UK tech raises on record at that time. France's Mistral AI raised a €600M Series B at €6B valuation in mid-2024.

What Does the M&A Wave Tell Us About AI Funding?

AI acquisitions hit 782 in 2025 — over 1.5x the prior year — revealing that acquisition, not IPO, is now the dominant exit path for AI-backed startups, per CB Insights.

Acquisitions of AI startups hit record levels in 2025, with 782 exits — more than 1.5 times 2024's count — signaling that the startup-to-acquisition path is becoming the dominant AI exit strategy.

CB Insights' 2025 State of AI report confirmed the spike. AI represented 7.5% of all venture M&A in 2025, up from 4.9% in 2024. The US led, with acquisitions of American AI startups up 1.85x year-over-year.

About 10% of those acquisitions involved AI agents or related infrastructure — and many were among the year's largest transactions. Meta's acquisition of Manus for approximately $3B and ServiceNow's acquisition of Moveworks for $2.85B were the headliners. But smaller deals outnumbered large ones: Workday paid $1.1B for Sana Labs; NICE paid $955M for Cognigy; Atlassian paid $610M for The Browser Company.

The pattern reveals something important about the funding data: many AI startups that raise early-stage rounds are not building toward IPO. They're building toward acquisition. That changes how funding rounds should be read — not as steps toward public markets, but as value-building milestones before a strategic acquisition by a larger enterprise software or platform company.

How Are AI Unicorns Forming Differently Than Before?

In 2025, 75 new AI unicorns formed — 61% of all new unicorns globally — with more reaching $1B valuation at commercial scale than in any prior year, per CB Insights data.

In 2025, 75 new AI unicorns emerged — 61% of all new unicorns globally — and many of them hit $1B+ valuations while already operating at commercial scale, a meaningful shift from 2024.

CB Insights tracks "Commercial Maturity" — a proprietary score measuring a private company's ability to compete for customers and serve as a commercial partner. In 2024, more than half of new AI unicorns were still at the validating or deploying stages when they crossed $1B. By 2025, that had changed: a higher share were already at the scaling stage. CB Insights noted this as evidence that the AI market is maturing, "with companies moving from more experimental technology to proven business models with real revenue and customers."

AI unicorns also reach that status faster and with smaller teams. CB Insights data from 2024 shows that new AI unicorns had a median team size of 203 employees versus 414 for non-AI unicorns at the same threshold. And they got there in a median of two years, compared to nine years for non-AI unicorns. The cost of AI development compresses timelines by letting small teams build products that previously required far larger engineering organizations.
