Anthropic IPO by December 31, 2026 priced at 91.5% on Polymarket, down 3.4 points, on $1.5M traded

Anthropic contract slips but remains above 90%

Polymarket’s contract on whether Anthropic will hold an IPO by December 31, 2026 was priced at 91.5%, down 3.4 percentage points, with $1.5M traded in the supplied market snapshot published Oct 30, 2026 at 3:24 PM ET.

The price continued to imply a strong expectation of an IPO before the deadline, despite the decline. It represents traders’ assessment of the outcome, not confirmation of a listing.

No fresh catalyst identified

The accompanying news summary reported no significant new platform headline in the preceding 30 minutes. Its search returned previously surfaced material, leaving the supplied reporting without a fresh catalyst that explains the repricing.

According to predictionbubbles.net, its finance board reports probability changes over the preceding 24 hours and refreshes data every 15 minutes. The site distinguishes total traded volume from price movement: the $1.5M figure should therefore not be read as money traded during the decline.

The supplied source page describes the broader tracking service rather than providing Anthropic-specific reporting or contract terms. It does not establish why the probability fell or provide details of what would qualify as an IPO for settlement.

What it means for prediction markets

• Direction and level differ: The 3.4-point decline signals weaker pricing, while the 91.5% level still heavily favors an IPO by December 31, 2026.
• A catalyst remains unverified: The supplied news check does not connect the move to a new development.
• Volume is not recent flow: The $1.5M total does not establish how much trading drove the latest change.
• Settlement details matter: Without the contract’s resolution terms, the precise requirements for a winning outcome cannot be assessed from the supplied material.
