Polymarket AI data shows the odds in the market 'Next Mythos-Class Model released by September 30, 2026?' fell 14 points to 63 percent on August 21, on $80,144 of volume.[^1][^2]

The read here is that traders are pricing timing risk, not existence risk: the question is when the model ships, not whether it ships. A 63 percent price still makes a release before the deadline more likely than not.

Polymarket data shows four crypto price markets resolved near 100 percent on the same day: Bitcoin at $74,000 on $217,102 of volume,[^7] Bitcoin at $76,000 on $181,646,[^8] Ethereum at $2,400 on $110,169,[^5] and Ethereum at $2,500 on $106,986.[^6]

Two Elon Musk tweet-count markets resolved near 1 percent: 140-164 tweets from August 20 to August 22 on $58,722 of volume,[^3] and 40-64 tweets on $92,197.[^4]

What would settle the open question is the actual release date of the next Mythos-Class model. Until then, the September 30 market is the scoreboard.
