“Will a Claude Mythos model be released by March 31, 2026?” is a prediction market on Polymarket with two tradeable outcomes, Yes and No. It belongs to the event “Claude Mythos released by…?”. The Yes price is the crowd's implied probability that the question resolves Yes; every trade on the public order book moves it.
The venue reports this market as closed. Its scheduled close is Apr 30, 2026. No resolved outcome is inferred from a closed or suspended state.
Vultax observes this market from Polymarket's public order book and data API and keeps its own record: 3 hourly price points from Mar 28, 2026 to Mar 31, 2026 (Yes between 0.4% and 1.6%); 16 loaded holder wallets, the largest ten holding 97.6% of the loaded shares; 173 recent public fills from 91 wallets. Each figure carries its observation time; nothing here is a return forecast.

Nine stops, one per figure on this page. Each stop says what the number is, why it matters, and what it reads right now for this market.
Each outcome trades as a share that pays $1 if it wins and nothing if it loses. Prices are quoted in cents, and Yes plus No add up to about one dollar.
A data leak on March 26, 2026, exposed Anthropic's unreleased "Claude Mythos" model, described as their most capable yet with significant advances in coding, reasoning, and cybersecurity, which the company has confirmed is now in early access testing. You can read more about that here: https://fortune.com/2026/03/26/anthropic-says-testing-mythos-powerful-new-ai-model-after-data-leak-reveals-its-existence-step-change-in-capabilities/. This market will resolve to "Yes" if Anthropic releases "Claude Mythos" or a model confirmed to be the same model referenced in the leak described above, and that model is made available to the general public by the listed date (ET). Otherwise, this market will resolve to "No." A qualifying model must be named "Claude Mythos" (e.g., Claude Mythos 1, Claude Mythos 5, Claude Mythos X, would count) or be confirmed to be the same model referenced in the leak by Anthropic or by a consensus of credible reporting. Products labeled as Claude Haiku, Sonnet, and Opus 4.7/5.0 or similar will not count for this market's resolution unless they are confirmed to be the same model referenced in the leak. For this market to resolve to "Yes," the qualifying model (as defined above) must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by Anthropic as being accessible to the general public. If a qualifying model is made publicly accessible and labeled with the relevant version name within the company’s official website, this will qualify as “publicly announced”. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public under the rules will not qualify. The primary resolution source for this market will be official information from Anthropic; however, a consensus of credible reporting will also be used.

The Yes price read as a chance. A share at 21.5¢ means the crowd gives Yes about a 21.5% chance right now. It moves with every trade, so it is a live forecast, not a verdict.
Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.
Dollars resting in the order book, waiting to be traded against. Deep liquidity lets a large order fill near the quoted price; thin liquidity means the price jumps when someone trades size.
The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.
The wallets holding the most shares on each side, and how much of the loaded sample the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.
The public fills, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.
Hourly closes of the Yes price. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.
Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.
