Anthropic IPO by December 31, 2026 priced at 96.5% on Polymarket, up 3.0 points, on $1.4M traded

Polymarket priced an Anthropic IPO by December 31, 2026 at 96.5%, up 3.0 percentage points, with $1.4M traded, according to predictionbubbles.net. The update was published on Oct 28, 2026 at 12:54 AM ET.

Higher pricing, limited catalyst information

The reported price puts the contract close to certainty, though it remains a market assessment rather than confirmation that an IPO will occur before the deadline.

The accompanying summary identified no significant new platform headline in the preceding 30 minutes. It said news searches had resurfaced material already used on Oct. 27, including the NBA preferred-partner deal and a reference to CFTC-NBA news.

The summary is truncated, and the source page text was unavailable. The supplied material therefore does not establish a connection between those recirculated items and the Anthropic contract’s move, or provide further details about an IPO timetable.

What it means for prediction markets

• Deadline risk remains central: The contract concerns an IPO by December 31, 2026, not simply whether Anthropic eventually goes public.
• The move lacks a documented fresh catalyst: The supplied update reports a 3.0-point increase but does not identify new Anthropic-specific reporting behind it.
• Volume is context, not confirmation: The reported $1.4M traded measures activity; it does not independently validate the 96.5% pricing.
