> Its experimental summary showed 41.5% at noon ET Nov. 6, but the readings lack matching observation times.

Polymarket’s “Anthropic IPO Date” market showed a 19% probability of no listing by Nov. 30 during a Nov. 7 check, while a separate reading from the platform cannot establish a shift.

The market lists an outcome for no IPO by Nov. 30, 2026. Its experimental summary showed 41.5% for that outcome at noon ET Nov. 6 (17:00 UTC), but the live market reading has no exact capture time. The observations do not provide a like-for-like measure of changing expectations.

The percentages reflect trading expectations for the market outcome, not a date set by Anthropic. The company’s Oct. 26 Form S-1 gives no specific IPO date and says the proposed sale would begin “as soon as practicable” after the registration statement becomes effective. Anthropic filed an S-1/A amendment Nov. 2.
