Definition
The flow of investment money, mostly venture capital plus big-tech cash, into AI companies, now the dominant force in startup investing.
At a glance
- In 2025, AI took 61 percent of all global venture capital, about 259 billion dollars, double its 2022 share[1].
- It is top-heavy: mega-rounds of 500 million dollars or more were 58 percent of AI funding, and OpenAI plus Anthropic alone took 14 percent of all venture investment[2].
- The U.S. captures roughly 75 to 79 percent, led by the San Francisco Bay Area.
- Most dollars go to infrastructure and foundation-model labs, not everyday AI apps.
Where it goes
A few giant bets dominate, not broad funding for ordinary tools. In Q1 2026, just three deals (OpenAI, Anthropic, xAI) took about 67 percent of all AI capital raised[3]. Big Tech fuels the boom directly: Microsoft, Amazon, Alphabet, and Meta plan roughly 650 billion dollars or more of AI spending in 2026[4].
What it means for you
You do not need investor money to benefit from AI. Expect a flood of cheap, fast-improving, investor-subsidized vendors competing for your business. The risk: spending far outpaces AI revenue, so when cheap capital tightens many funded startups will fail[5]. Pick durable vendors, not the hype.
Bottom line
The boom is real but top-heavy, so as a buyer just choose vendors that can outlast it.
