AI Firms Priced $300B+ of Stock in 2026, $100B More on Tap

AI companies have sold or priced more than $300 billion of new stock and mandatory convertible securities in 2026, with another roughly $100 billion of potential share sales still on tap. That running total excludes Anthropic's upcoming IPO, which has itself been reported as a raise of up to $100 billion.

"Volatile trading in AI-related stocks this past week has put a spotlight on investors' appetite for additional share offerings," Alex Eichenstein wrote in The Information on Saturday. The question in the headline is a pricing question as much as a supply one, covering both the volume and the prices companies could get if they opt to sell.

The timing matters. The report arrived at the end of a week in which AI-exposed names were marked down hard, and with Anthropic's own IPO roadshow reported to be slated for the week ahead. Among the structures inside the $300B+ tally are mandatory convertibles, which force conversion into equity at maturity rather than leaving that choice with the holder.

It is the third capital-markets alert in our tracker inside a week, after OpenAI's $11B first close at a $1.25T valuation landed below its $1.4T target, and Anthropic's $3.4B OnePWR generator order priced the capex side of the same balance sheet.
