Kalshi bettors gave an Anthropic IPO announcement before November almost no chance

what happened

Seeking Alpha reports that for most of October, the Kalshi prediction platform gave almost no chance to Anthropic publicly announcing its initial public offering before the month ended. On Monday the AI safety and research company submitted its S-1 registration statement to the Securities and Exchange Commission, and the shares are set to trade on the Nasdaq Global Exchange Market.

Under SEC rules, the filing must become public at least 15 days before the IPO roadshow begins. Anthropic, ticker ANT, posted a net loss of $80.7 billion in the first half of 2026, and roughly $72 billion of that came from non-cash revaluations of convertible debt and other financing instruments. The highest odds on Kalshi went to an official announcement before January 1.

why it matters

For markets, timing matters: the S-1 discloses the company's financing and losses before any possible listing, and investors will weigh that data against valuation expectations. The large non-cash revaluation shows how financing instruments can swing reported results. Prediction-market odds reflect participants' expectations but are not a price forecast.
