Anthropic’s Funding Boom Highlights AI’s Growing Share of U.S. Growth Capital

U.S. growth fundraising reached $440 billion in the first nine months of 2026, with artificial intelligence accounting for 71% of the total. Anthropic was among six companies that together raised $257 billion, concentrating 58% of all funding in the period. Rothschild & Co’s review says the nine-month total was 2.7 times the amount raised in the same period of 2025, across just over 500 deals of at least $100 million.
