AI funding surges — data

One quarter was enough to top an entire year. New venture charts shared by Andreessen Horowitz, the Silicon Valley firm known as a16z, line up with broader market data showing artificial intelligence soaked up a record share of startup money in the first three months of 2026. (x.com) (crunchbase.com) The simplest way to read the spike is this: a few giant companies raised sums that used to belong to whole sectors. OpenAI said on March 31, 2026 that it closed a $122 billion funding round at an $852 billion post-money valuation, which by itself is larger than many countries’ annual venture markets. (openai.com) That was not a one-off. xAI said on January 6, 2026 that it raised $20 billion in a Series E round, and Crunchbase reported on March 20, 2026 that Anthropic raised $30 billion at a $380 billion post-money valuation. (x.ai) (crunchbase.com) When rounds get that large, the quarterly totals stop behaving like normal startup statistics. Crunchbase said global venture funding reached about $300 billion in the first quarter of 2026, up more than 150% from both the prior quarter and the same quarter a year earlier, and it tied the jump directly to spending on artificial intelligence compute and frontier labs. (crunchbase.com) Another dataset shows the same shape. CB Insights said global venture funding hit a record $286 billion in the first quarter of 2026, while investor participation kept shrinking, which means more money was being concentrated into fewer hands. (cbinsights.com) That concentration is the real story. TechCrunch reported that four mega-deals into OpenAI, Anthropic, xAI, and Waymo did much of the work in pushing the quarter to a record, so the boom is not a broad reopening for every startup with an artificial intelligence slide deck. (techcrunch.com) The money is clustering around companies that need enormous amounts of hardware. CoreWeave’s filing with the United States Securities and Exchange Commission said its revenue grew from $229 million in 2023 to $1.9 billion in 2024, which shows why investors are treating graphics processing unit clouds and model infrastructure less like software apps and more like power plants. (sec.gov) At the same time, selling artificial intelligence is getting harder than funding it. PitchBook’s March 16, 2026 note on consumer artificial intelligence said the market is seeing capital concentration, stage shifts, and tougher monetization and distribution conditions, which is venture language for “capital is abundant at the top, but customers are not buying everything.” (pitchbook.com) Andreessen Horowitz is part of the backdrop here, not just a commentator. The firm said in January 2026 that it raised more than $15 billion in new funds, including $1.7 billion for infrastructure and $6.75 billion for growth, after accounting for more than 18% of United States venture capital dollars allocated in 2025. (a16z.com) So the picture is not “artificial intelligence is hot” in the vague old sense. It is that a small number of model makers and compute suppliers are now absorbing capital at a scale that can make one quarter look bigger than a year, while the rest of the startup market still has to prove it can turn demos into durable revenue.
