# Kalshi Market Saw Little Chance of Anthropic IPO Announcement Before Nov. 1 By Enna Lee Canonical URL: https://www.tokenpost.com/news/investing/41452 Published: 2026-10-26T23:53:22.000Z Updated: 2026-10-26T23:53:22.000Z Section: Investing > A separate Kalshi contract for a qualifying IPO announcement by year-end placed Anthropic at 75% on Oct. 19. Kalshi’s short-term prediction market assigned Anthropic almost no chance of announcing an initial public offering (IPO) before Nov. 1 during most of October. The deadline concerns an announcement, not when shares would begin trading. The market’s percentage reflects trading expectations on the contract, not a company statement. The short-term contract has a different deadline from the [separate 2026 IPO announcement market](). On Oct. 19, that longer-dated contract placed Anthropic at 75% for a qualifying announcement by the end of 2026. The percentages describe separate outcomes, not a shift in odds within one contract. The 2026 contract counts an effective SEC Form S-1, offering pricing or an exchange assigning a ticker as a qualifying milestone. A confidential S-1 filing alone does not meet that contract’s standard. The shorter contract’s deadline is Nov. 1. ## Links in this article - [separate 2026 IPO announcement market](https://www.tokenpost.com/news/investing/35068)
