AI funding in January 2026 reached $44.46B across 477 venture deals. One round, xAI’s $20B Series E on January 6, made up 45.0% of that total. Take xAI out and the other 476 deals shared $24.46B. Four rounds of $1B or more took 55.3% of the month’s capital, and the five largest took 57.0%.
That concentration is the main finding. The long tail was busy (170 Seed and Pre-Seed rounds, a median disclosed round of $12.85M), but it moved very little money. Below are the largest rounds, then the split by stage, sector, investor and country.

January 2026 AI Funding by the Numbers
| Metric | Value |
|---|---|
| Total funding | $44.46B |
| Venture deals | 477 |
| xAI share of dollars | 45.0% |
| Rounds of $1B or more | 4 rounds, $24.6B (55.3%) |
| Top 5 rounds combined | $25.35B (57.0%) |
| Mega-rounds ($100M or more) | 65 deals, $37.66B (84.7%) |
| Median disclosed round | $12.85M |
| Seed and Pre-Seed | 170 deals (35.6%), 4.49% of dollars |
| AI agent deals | 176 of 477 (36.9%) |
Mega-rounds of $100M or more numbered 65, about one deal in seven, and absorbed $37.66B. The 170 Seed and Pre-Seed rounds together raised about $2.0B, less than the gap between xAI and the second-largest round of the month.
The Top 10 AI Deals of January 2026
xAI’s round was ten times the size of the next one, DayOne Data Centers’ $2B Series C. Only four rounds crossed $1B: xAI, DayOne, Skild AI and Humain. Valuations below are the figures reported at announcement; where a company did not disclose one, the cell says so.
| # | Company | Round | Date | Valuation | Lead | HQ |
|---|---|---|---|---|---|---|
| 1 | xAI | $20B Series E | Jan 6 | Over $230B (reported) | None named (Valor, Fidelity, Qatar Investment Authority, MGX, StepStone, NVIDIA, Cisco participated) | Palo Alto |
| 2 | DayOne Data Centers | $2B Series C | Jan 5 | Not disclosed | Coatue | Singapore |
| 3 | Skild AI | $1.4B Series C | Jan 14 | Over $14B | SoftBank Group | Pittsburgh |
| 4 | Humain | Up to $1.2B debt financing | Jan 21 | N/A | National Infrastructure Fund | Riyadh |
| 5 | Waabi | $750M Series C | Jan 28 | Not disclosed | Khosla Ventures, G2 Venture Partners | Toronto |
| 6 | StepFun | $718M Series B extension | Jan 26 | Not disclosed | No single lead named | Shanghai |
| 7 | Etched | $500M (series not stated) | Jan 13 | About $5B | Stripes | San Jose |
| 8 | Humans& | $480M Seed | Jan 20 | $4.48B | SV Angel, Georges Harik | San Francisco |
| 9 | Redwood Materials | $425M Series E | Jan 28 | Over $6B (reported) | Eclipse | Carson City, NV |
| 10 (tie) | Cyera | $400M Series F | Jan 8 | $9B | Blackstone | New York |
| 10 (tie) | ClickHouse | $400M Series D | Jan 16 | $15B | Dragoneer | San Francisco |
Three notes on the list. Waabi’s $750M excludes a separate milestone-based commitment from Uber of up to $250M. Redwood Materials’ $425M is the final close of a Series E first announced in October 2025, and it is counted once, in January. DayOne’s January figure was the first close of its Series C; the round reached a final close of $4.5B in June 2026.
Two large January transactions are not venture rounds and sit outside every total here. USA Rare Earth’s $1.6B package from the U.S. Commerce Department is mostly a loan to a Nasdaq-listed company, with an equity stake attached. MiniMax listed in Hong Kong on January 9, which makes it an IPO, not a private round.
Compute and physical AI fill most of the top 10. DayOne and Humain build data-center capacity, Etched designs inference chips, and Skild AI and Waabi build models for robots and trucks. Skild AI’s round at a valuation above $14B was the largest robotics raise of the month; our top AI robotics startups list tracks the companies behind it. Humans& raised $480M at the Seed stage, the largest Seed round in the January data by a wide margin.
Funding by Stage: Early Rounds Had the Deals, Late Rounds Had the Money
Seed and Series A made up 232 of January’s 477 deals but raised $4.98B combined. Eight Series E and Series F rounds raised $21.83B, and xAI’s round accounts for most of that. Series C was the strongest mid-stage band at $6.22B across 27 deals, carried by DayOne, Skild AI and Waabi.
| Stage | Deals | Dollars |
|---|---|---|
| Pre-Seed | 49 | $0.11B |
| Seed | 121 | $1.88B |
| Series A | 111 | $3.09B |
| Series B | 47 | $3.52B |
| Series C | 27 | $6.22B |
| Series D | 19 | $3.14B |
| Series E and F | 8 | $21.83B |
| Growth | 22 | $0.86B |
| Debt | 11 | $2.32B |
| Strategic | 12 | $0.08B |
| Other or not stated | 50 | $1.40B |

Where the Money Went: Sector Breakdown
A company listed under two verticals counts its full round in both, so the sector totals add up to more than $44.46B. Developer Tools & AI Infrastructure took $24.71B across 42 deals. Without xAI it still raised $4.71B, more than every other vertical except Manufacturing & Industrials.
| Vertical | Dollars | Deals |
|---|---|---|
| Developer Tools & AI Infrastructure | $24.71B | 42 |
| Manufacturing & Industrials | $6.35B | 53 |
| Energy & Sustainability | $3.74B | 33 |
| Transportation & Mobility | $3.19B | 33 |
| Health & Biotech | $2.95B | 83 |
| FinTech | $2.89B | 73 |
| Marketing & Sales Tech | $1.71B | 49 |
| Cybersecurity | $1.41B | 26 |
Manufacturing & Industrials was second at $6.35B, with DayOne, Skild AI and Etched all classified there. Health & Biotech had the most deals of any vertical (83) but an average round of about $36M. FinTech looked similar, with 73 deals and $2.89B. Cybersecurity raised $1.41B across 26 deals, and Cyera’s $400M Series F was more than a quarter of it; our AI cybersecurity startups roundup covers the rest of that field.
The Investor Activity Map: Who Showed Up Most
Y Combinator backed the most January AI rounds, 24, half of them at Seed or Pre-Seed and most of the rest at Series A. Lightspeed Venture Partners followed with 16, then Sequoia Capital with 14 and Andreessen Horowitz with 13.
| Investor | January AI rounds |
|---|---|
| Y Combinator | 24 |
| Lightspeed Venture Partners | 16 |
| Sequoia Capital | 14 |
| Andreessen Horowitz | 13 |
| Accel | 10 |
| Bessemer Venture Partners | 10 |
| Alumni Ventures | 10 |

| General Catalyst | 7 |
NVIDIA and its venture arm NVentures participated in 14 rounds between them, including xAI and Humans&, usually alongside a financial lead. Sovereign and state-linked capital showed up at the top of the market: Qatar Investment Authority and MGX participated in xAI’s round, Saudi Arabia’s National Infrastructure Fund provided Humain’s financing, and the Indonesia Investment Authority joined DayOne’s Series C.

AI Native vs Augmented vs Adjacent: The Classification Mix
Every company is classified as AI Native (the AI is the product), AI Augmented (an existing product uses AI), AI Adjacent (it sells into the AI stack, such as data centers or databases) or AI Platforms (companies building the foundation models, model chips and general-purpose robot models that others build on).
| Class | Deals | Share of deals | Dollars |
|---|---|---|---|
| AI Native | 300 | 62.9% | $9.14B |
| AI Augmented | 128 | 26.8% | $5.55B |
| AI Adjacent | 36 | 7.5% | $6.06B |
| AI Platforms | 13 | 2.7% | $23.71B |
AI Platforms had the fewest deals and the most money: 13 rounds raised $23.71B, or 53.3% of the month. That group includes xAI, Skild AI, StepFun, Etched and Humans&. AI Native companies made up most of the deal count, 300 of 477. AI agents were the most common product theme, covering 176 deals (36.9%); our AI agent funding guide covers those companies.
Geography: Where January’s AI Capital Landed
U.S.-headquartered companies raised $33.26B (74.8% of dollars) across 216 deals. Without xAI, the U.S. share of the remaining $24.46B falls to 54.2%. By deal count the U.S. had 45.3%, well below its dollar share.
| Country | Dollars | Deals |
|---|---|---|
| United States | $33.26B | 216 |
| Singapore | $2.16B | 12 |
| United Kingdom | $1.42B | 39 |
| Saudi Arabia | $1.21B | 5 |
| India | $1.06B | 61 |
| Canada | $1.05B | 17 |
| China | $0.99B | 7 |
India ranked second by deal count (61) and fifth by dollars ($1.06B), with only one round of $100M or more. The United Kingdom was third by deal count with 39 rounds and $1.42B. Singapore’s $2.16B was mostly DayOne, Saudi Arabia’s $1.21B was almost entirely Humain, and StepFun made up most of China’s $0.99B. Among U.S. metros, the San Francisco Bay Area led with 65 deals, followed by New York City (53), Boston (11), Austin (7) and Los Angeles (7). A company with offices in two metros counts in both; AI startup funding by city has the full ranking.
How January Compares With the Rest of Q1 2026
January was the smallest month of the quarter. February closed at $75.16B across 555 deals and March at $154.18B across 576, which puts Q1 2026 at $273.8B, with January contributing 16.2%. The February report and March report cover each month in detail, and AI mega-rounds in 2026 tracks the largest rounds across the year.
January’s own mix leaned on compute and physical AI. Data-center builders (DayOne, Humain), a chip designer (Etched) and robotics and autonomy companies (Skild AI, Waabi) filled five of the top seven places, all behind a single $20B round that took almost half the month’s capital.
Methodology
Figures cover 477 venture rounds announced by AI startups worldwide between January 1 and January 31, 2026. Every record is verified, deduplicated and AI-classified. Amounts in other currencies are converted to U.S. dollars. Secondary sales, public-company financings and IPOs are excluded, which is why USA Rare Earth and MiniMax do not appear. Sector totals use multi-vertical attribution, so they sum to more than the global total. Metro counts credit each city a company lists. Investor counts are rounds in which a firm participated, as lead or co-investor. Valuations are those reported at announcement. Data current as of October 31, 2026.
