. @business reported on 20 August that @AnthropicAI is preparing to file publicly for an IPO as soon as the end of the month, targeting a raise that matches or beats SpaceX's record $75B. @Kalshi and @Polymarket list contracts on both parts of that: when Anthropic lists, and what it will be worth. Kalshi's odds of an IPO announcement by 1 October doubled, 22% to 48%. Polymarket's odds of shares trading by 30 September doubled, 11% to 23%. But Polymarket's expectations for what Anthropic will be worth didn't change. Traders still see it listing around $2.0–2.25T, roughly twice the $965B May round.
