55 US AI Startups Raised $100 Million or More in 2025

Fifty-five US AI startups raised rounds of $100 million or more in 2025, according to a TechCrunch tally. The count is the clearest signal yet that capital for artificial intelligence did not cool. It concentrated.

The TechCrunch list covers only US companies. It counts only rounds that crossed the $100 million line. That filter matters. Smaller AI seed deals happened in the hundreds, if not thousands, last year. What the list isolates is the top tier — the companies investors backed with nine-figure checks.

What does the number actually measure?

A list of 55 companies is not a market survey. It is a scoreboard. Each entry marks a moment when a venture firm, a corporate investor, or a syndicate decided a single AI company deserved at least $100 million in one commitment. Fifty-five such decisions cleared that bar in 2025.

The mechanism behind the list is simple. Investors write large checks when they expect large outcomes. AI, and above all foundation models and their applications, kept that expectation alive through 2025. The list is the residue of those expectations, sorted into rows.

Why does the $100 million threshold matter?

A $100 million round was once rare for a startup at any stage. In 2025 it was the entry ticket to the top tier of AI. TechCrunch set the cutoff at that figure, and 55 US companies still qualified.

That threshold separates two games. Below it, startups raise to build a product. Above it, startups raise to build infrastructure, buy compute, and race competitors. The 55 names on the list play the second game. Their capital needs scale with chips, data centers, and talent, not with headcount alone.

How concentrated was the money?

The list counts startups, not total dollars. Each of the 55 rounds could sit at $100 million or run well beyond it. TechCrunch did not publish a combined sum in the headline figure, so the aggregate remains open.

Even without a total, the shape is clear. The money flowed to a small group of US companies out of the entire AI field. If a reader wants one comparison, think of it this way: most US startups will never raise $100 million across their entire lives. These 55 did it in single rounds.

What does the list say about geography?

The tally covers the United States only. AI startups in Europe, Asia, and elsewhere raised large rounds in 2025 too, but they fall outside this count. A US-only frame with 55 qualifying companies still makes the point: the nine-figure AI round became an American routine, not an exception.

What should investors and founders watch next?

The 2025 list sets a baseline. If fewer companies clear $100 million in 2026, capital tightened. If more clear it, the race for AI scale continued. If the same names reappear at higher valuations, the market consolidated around a handful of winners.

TechCrunch's count gives the market a fixed reference point. Fifty-five US AI startups. One year. One hundred million dollars each, at minimum.
