Polymarket priced the probability of an Anthropic IPO by December 15, 2026 at 72.5% in the supplied market snapshot, published Oct 24, 2026 at 6:09 PM ET. The summary reported a 5.0-point decline and $271K in traded volume.
The probability was also down 1.0 point since Oct. 23. Those figures show a softer market assessment, although an IPO within the specified deadline remained the more likely outcome at the quoted price.
What the data establishes
According to predictionbubbles.net, its finance board displays market-implied probabilities, changes over the preceding 24 hours and total traded volume where available. Its data refreshes every 15 minutes, while trading on the underlying venues continues between updates.
The supplied source page provides that methodology but does not contain an Anthropic-specific entry, contract rules or reporting on the company’s listing plans. The headline and summary therefore establish the quoted price and movement, but the material does not identify a catalyst for the decline or independently confirm an IPO timetable.
PredictionBubbles also cautions that related contracts across Polymarket and Kalshi can differ in wording, settlement rules and deadlines. No comparable Kalshi price for this Anthropic question is included in the supplied material.
What it means for prediction markets
The deadline defines the bet: The 72.5% price concerns an IPO by December 15, 2026, not whether Anthropic will eventually go public.
Sentiment weakened without reversing: Both reported declines point downward, but the quoted probability still favors an IPO before the cutoff.
Volume is not an explanation: The $271K figure records trading activity; the supplied material does not establish why traders repriced the outcome.
Settlement details remain a gap: Without the contract’s full rules, readers cannot determine precisely what event would qualify as an IPO for resolution.
