The Kalshi contract on whether Anthropic will release Mythos before Jan 1, 2027 was priced at 8.0%, down 3.0 percentage points, with $305K traded, in the Oct 26, 2026 · 5:09 PM ET snapshot. According to PredictionBubbles, the contract was among the declining markets on its technology board.
A lower probability, without an identified catalyst
PredictionBubbles measures price changes over the preceding 24 hours. The move therefore reflects a lower market-implied likelihood of a release before the contract’s cutoff, rather than a confirmed change to Anthropic’s plans.
The supplied material does not identify an announcement, reporting development or other catalyst for the decline. It also does not include the contract’s detailed resolution criteria, limiting what can be concluded about precisely which release circumstances would qualify.
Reading the board
According to PredictionBubbles, its technology page tracks 52 open markets: 15 from Kalshi and 37 from Polymarket. Data refreshes every 15 minutes, while trading on the underlying venues continues between updates.
The site distinguishes its ranking of the largest absolute 24-hour probability changes from its ranking by total traded volume. The Mythos contract’s $305K figure is total traded volume, not a measure of trading during the decline. PredictionBubbles displays venue prices rather than accepting wagers or holding funds.
What it means for prediction markets
The signal is deadline-specific: The 8.0% price concerns a Mythos release before Jan 1, 2027, not whether a release will ever occur.
Price action is not confirmation: The 3.0-point decline shows a shift in market pricing; the supplied material provides no explanation for that shift.
Rules and timing matter: The snapshot may differ from subsequent venue prices, and the contract’s detailed release criteria are not included in the source material.
