Series A funding has reached a new scale.
Global startups secured at least 114 Series A rounds worth $100 million or more in 2026, producing around $33 billion in total funding. At least 12 of those rounds reached $500 million or more, turning a stage usually associated with early validation into a venue for enormous capital commitments.
AI dominates the pattern. More than 70% of the $100 million-plus Series A rounds went to AI-focused startups in 2026, making the sector the clear center of large early-stage financing.
That concentration matches the broader funding market. In the first half of 2026, venture and growth funding for AI startups totaled an estimated $394 billion, or roughly 77% of all investment capital.
AI Funding Is Pulling Away From the Pack
The largest individual rounds show how quickly the scale has expanded. River AI, a Silicon Valley-based platform for training and serving custom models, raised $1.2 billion, while Xpeng Robotics, a China-based developer of AI-enabled humanoid robots, secured $900 million.
Those deals sit far above the $100 million threshold used to track the year’s large Series A rounds. They also show the range of businesses attracting capital, from model infrastructure to AI-enabled hardware.
The funding totals point to a market that is placing enormous bets on AI startups before later financing stages. The numbers do not describe a quiet shift in venture strategy; they describe a capital pool in which AI accounts for most investment funding and more than 70% of the largest Series A rounds.
That imbalance gives the sector a clear financial advantage. Startups outside AI can still raise large rounds, but the 2026 figures show that the biggest checks are concentrated in companies tied to models, robotics, and related systems.
U.S. Deals Lead a Major Share
Roughly half of the $100 million-plus Series A rounds and funding went to U.S.-based startups in 2026. The United States recorded about 62 deals with a collective value of around $15 billion.
That leaves the other half of these large rounds and funding distributed outside the United States, reflecting the global reach of the current financing cycle. The named deals span Silicon Valley and China, while other large raises add satellite manufacturing and drug discovery to the picture.
EnduroSat, a Bulgarian satellite manufacturer, raised $205 million, with Riot Ventures and Atreides Management as lead investors. The round places a space technology company among the startups benefiting from the same funding environment that has produced billion-dollar AI financing.
Anew Labs, a Chinese AI drug-discovery spinout from ByteDance, raised $290 million at a $1.5 billion valuation. HSG, IDG Capital, and Hillhouse Investment invested in the company.
EnduroSat and Anew Labs also underline an important detail in the totals: large startup financing is not limited to one type of AI company or one national market. The 2026 rounds include custom-model platforms, humanoid robots, AI drug discovery, and satellite manufacturing—different businesses competing for access to the same unusually deep pool of capital.
The scale creates a clear dividing line in venture funding. A $100 million Series A is now part of a recorded group of at least 114 deals, while 12 rounds reached $500 million or more and individual financings climbed to $1.2 billion.
For 2026, the message is difficult to miss: investors are directing a major share of startup capital toward AI, and they are doing it at valuations and round sizes that would have looked exceptional anywhere else. Venture capital has not misplaced the decimal point. It has simply decided that AI deserves several of them.
