Anthropic release Mythos before Dec 1, 2026 priced at 7.0% on Kalshi, on $215K traded

Anthropic’s release of Mythos before Dec 1, 2026 was priced at a 7.0% probability on Kalshi, with $215K traded, according to the supplied market snapshot published Oct 29, 2026 at 8:24 PM ET.

The price puts a release before the deadline firmly in the market’s low-probability range. The supplied material contains no Anthropic announcement or product-development reporting to explain that assessment.

A snapshot of the wider tech board

According to PredictionBubbles, its Oct. 30, 00:18 UTC crawl covered 56 open technology markets with $68.1M traded. The Mythos December 1 release contract appeared among the board’s traded markets.

The tracked markets comprised 15 on Kalshi and 41 on Polymarket. PredictionBubbles aggregates prices from both venues and refreshes its data every 15 minutes, while trading on the underlying platforms continues between updates.

Volume is not momentum

PredictionBubbles separates its volume rankings from its rankings of absolute probability changes over the preceding 24 hours. The $215K figure therefore describes trading activity in the Mythos contract, not the direction or size of a recent price move. No contract-specific 24-hour change was provided.

The board’s largest market by traded volume at its last refresh concerned whether the U.S. would confirm that aliens exist before 2027, with $29.7M traded on Kalshi, according to PredictionBubbles. That provides context for the breadth of the board, rather than evidence about Anthropic’s release prospects.

What it means for prediction markets

• The 7.0% reading is a market assessment, not a release announcement. The supplied reporting offers no independent confirmation of Anthropic’s plans for Mythos.
• The deadline defines the question. This contract concerns a release before Dec 1, 2026, not whether Mythos will eventually be released.
• Activity and repricing are different signals. The $215K traded does not establish whether expectations have recently risen or fallen.
• Comparisons require matching rules. PredictionBubbles notes that related questions across Kalshi and Polymarket can have different wording and resolution criteria; the supplied material does not identify a corresponding Mythos contract on Polymarket.
