Through September 2026, the PitchBook-NVCA Venture Monitor reports $515.8 billion across an estimated 14,199 U.S. venture deals. AI companies received 82.7% of that dollar value, with a handful of very large rounds contributing heavily. These figures show the scale and concentration of capital at stake in venture decisions. Deals are funding transactions, not counts of new ideas or unique startups. The data do not establish how often investors misunderstand claims; that question requires evidence about their actual evaluation process.
