Anthropic have the highest IPO Market Cap 2026 priced at 48.6% on Polymarket, up 10.2 points, on $1.4M traded

Anthropic’s Polymarket contract on whether it will have the highest IPO market capitalization in 2026 stood at 48.6%, up 10.2 percentage points over 24 hours, with $1.4M traded, according to the supplied PredictionBubbles snapshot published Oct 29, 2026, at 12:54 AM ET.

A sharp repricing, but below 50%

The move lifted the contract’s implied probability substantially, while leaving it below 50%. The supplied material does not identify a news event behind the change or provide the contract’s detailed resolution criteria.

PredictionBubbles distinguishes price movement from trading activity: its movers ranking uses absolute probability changes over the preceding 24 hours, while its volume ranking uses total traded volume. The $1.4M figure therefore should not be read as turnover generated during Anthropic’s latest price rise.

Board snapshots differ

The summary’s Oct. 29, 04:40 UTC crawl recorded 188 open markets and $163.4M traded across the finance board. The supplied page text separately lists 189 markets, comprising 15 from Kalshi and 174 from Polymarket. Those counts reflect different supplied snapshots rather than a single consistent board reading.

According to PredictionBubbles, its finance data refreshes every 15 minutes, although trading on the underlying venues continues between updates. The page identifies the Polymarket contract asking whether there will be no Fed rate cuts in 2026 as the board’s most-traded finance market at its last refresh, with $9.2M traded.

What it means for prediction markets

• The signal is a change in expectations: Anthropic’s 10.2-point rise marks a sizable repricing, not confirmation of the eventual IPO outcome.
• Volume and momentum measure different things: The $1.4M total provides trading context but does not establish how much activity drove the 24-hour move.
• Timing and contract terms matter: The 48.6% reading is a snapshot. The supplied material omits the detailed resolution rules, and PredictionBubbles cautions that related questions can have different wording and settlement criteria across venues.
