The top funded AI startups of 2026 are OpenAI, Anthropic and xAI, whose megarounds helped push foundational AI funding to a record $178 billion in the first quarter alone, by Crunchbase’s count. Since then, billion-dollar rounds have kept coming: Crunchbase counted a record 27 in Q3, and in October DeepSeek raised about $15.9 billion at a reported $90 billion valuation. This page collects the figures Crunchbase and its coverage have published, attributes each one, and flags where trackers disagree. It is not investment advice.
Which AI startups raised the most in 2026?
According to Crunchbase’s Q1 review (April 2, 2026, data as of March 31):
| Company | Round reported | Detail from Crunchbase |
|---|---|---|
| OpenAI | $110 billion megaround in February; $10 billion added later | Reporting on March 31 put the round at $122 billion. Crunchbase calls the first tranche the largest venture deal of all time |
| Anthropic | $30 billion Series G | Led by GIC and Coatue at a $380 billion post-money valuation; nearly $64 billion raised since its 2021 founding |
| xAI | $20 billion Series E | $42.7 billion in reported debt and equity raised to date; effectively merged with SpaceX in early 2026 |
| Advanced Machine Intelligence (AMI) | $1.03 billion in March | Co-founded by Yann LeCun; the largest seed round ever for a European startup, at a reported $3.5 billion valuation |
| World Labs | $1 billion | Founded by Fei-Fei Li; investors included AMD, Autodesk, Fidelity and Nvidia |
Several of these figures are “reported” rather than confirmed by the companies, including OpenAI’s $122 billion, AMI’s valuation and xAI’s debt-and-equity total. Crunchbase’s totals are its own data, and the article does not set out the methodology in its text.
How much money went into AI in 2026 so far?
Crunchbase counted $178 billion going to foundational AI startups across 24 deals by March 31, 2026, against $88.9 billion across 66 deals in all of 2025 and $31.4 billion across 52 deals in 2024.
| Period | Global venture funding | AI share | Crunchbase notes |
|---|---|---|---|
| July 2026 | $55 billion (up 69% year over year) | $35 billion, about 63% | 13 billion-dollar rounds, the most in a single month |
| Q3 2026 | $159 billion (down 25% from Q2’s $212 billion; up 53% from Q3 2025) | $102 billion, 64% | Record 27 rounds of $1 billion or more |
| October 2026 | $59 billion (up 45% year over year) | 66% | Seven billion-dollar rounds, just over 40% of the month’s funding |
Crunchbase says funding for the first three quarters of 2026 totalled $679 billion, the highest for the first three quarters of any year. Its Q3 review (October 5, 2026) also notes the AI share was down from the two previous quarters but 14 percentage points above Q3 2025.
What were the biggest rounds from July to October?
- July. Per Crunchbase’s July report (August 4, 2026), Safe Superintelligence reportedly raised $5 billion from Nvidia, Moonshot AI raised $3.5 billion after the release of its Kimi K3 model, and Kling AI raised $2.8 billion.
- Q3. Databricks and Safe Superintelligence each raised $5 billion; Crusoe, Moonshot AI, Mistral AI, Nscale, The Boring Co. and Kling AI each raised more than $3 billion. Crunchbase gave no lead investors or valuations for these in the article.
- October. In its October report (November 3, 2026), Crunchbase lists DeepSeek at $15.9 billion at a $90 billion valuation, followed by Re:Build ($2.1 billion), Axiom ($2 billion), Ramp ($1.85 billion), Tenstorrent ($1.5 billion Series E), Kalshi ($1 billion Series E) and Flapping Airplanes ($1 billion Series A).
Crunchbase says the DeepSeek round is the largest venture deal ever for a Chinese company, making it the second most valued Chinese company after ByteDance and the third most valued private frontier lab after Anthropic and OpenAI.
What else stood out in October?
Crunchbase says the US led October with $28 billion and China followed with $20.6 billion, and that seven companies raised billion-dollar rounds. Not every large round was a model lab: the list includes Ramp, a spend-management company that said its annual recurring revenue reached $2 billion, Kalshi in prediction markets, Axiom in power and grid capacity for data centers, and Tenstorrent in open-source semiconductors. Crunchbase adds that semiconductor companies gained share of funding that month, and that private equity led much of the billion-dollar funding alongside multistage firms including Sequoia Capital, Index Ventures and Lux Capital. The report does not tie those investors to specific deals, so we do not either.
Why do trackers disagree on DeepSeek?
Because the round was reported in stages. CNBC reported on October 6, citing unnamed people, that DeepSeek was considering up to 100 billion yuan (about $14.9 billion) at a valuation of about 500 billion yuan (about $75 billion), with the amount still liable to change, and that CATL, Geely Auto, Monolith Management and Loyal Valley Capital had committed capital. Crunchbase’s later report lists the closed round at $15.9 billion and $90 billion and does not name DeepSeek’s investors. Treat the earlier figures as pre-close reporting and the Crunchbase numbers as the later tally.
Which stages and sectors took the money in Q3?
Crunchbase’s Q3 review says late-stage funding totalled $105 billion and early-stage funding $40.6 billion. It also says the aerospace, robotics, data center, semiconductor and energy sectors each raised $10 billion or more, so funding that follows the AI boom reaches the hardware and infrastructure around the models as well as the models themselves. The same review reports a record 27 companies raising rounds of $1 billion or more, and says those companies took around a third of all global venture capital raised in the quarter. When so few deals carry so much of the total, one or two rounds closing a month earlier or later can shift a quarterly figure noticeably.
What about acquisitions and exits?
Crunchbase’s Q3 review also lists two large deals: Nvidia’s $12.9 billion bid for Hugging Face and AMD’s announced $8.2 billion deal to acquire World Labs. For the public-market side of one of these companies, see our summary of Anthropic’s S-1 filing, and for the xAI-SpaceX link, the SpaceX IPO.
How should you read these numbers?
- Headline round sizes can include staged commitments and compute deals, not only cash at closing.
- Trackers disagree on dates and amounts; check the original source before quoting.
- A few very large rounds dominate the totals: Crunchbase says the 27 billion-dollar rounds in Q3 took around a third of all global venture capital.
- Funding shows investor appetite, not revenue or product quality. Where the money goes next, including cloud capacity, is covered in our AWS, Azure and Google Cloud comparison.
