Anthropic booked more than $660M in non-cash expenses from October 2025 through March 2026 for matching the stock its employees pledge to charity, a cost likely to climb into the billions after its IPO, according to Cory Weinberg at The Information. Staff hired before 2025 can donate as much as half of their shares and get a 3-to-1 match, while later hires get 1-to-1 on as much as a quarter, and every matched share is new stock that dilutes other investors. Anthropic’s 2025 charitable contributions reached $540M, while the largest comparable non-cash gift at any Fortune 500 company was BlackRock’s $109M, according to Calcbench data. Anthropic leaves the expense out of the adjusted operating profit it showed prospective IPO investors, which Calcbench says is rare.
