This market asks whether Anthropic will publicly release a model called Claude Mythos, or a model clearly confirmed to be the same one exposed in the March 26, 2026 leak, by June 15, 2026. It is worth watching because the question is not just whether Anthropic is testing a new model, but whether that model reaches public access before the deadline and under the market’s strict naming rules.
The event centers on Anthropic and the unreleased Claude Mythos model described in the market description as a major step up in coding, reasoning, and cybersecurity. To count for a Yes, the model must be named Claude Mythos or be officially confirmed as the same leaked model, and it must be publicly accessible by June 15, 2026 at 00:00 UTC as the market defines the deadline. Closed testing alone does not qualify; the release has to reach the general public through something like an open beta or an open rolling waitlist.
There is still uncertainty over both timing and branding. Anthropic could keep the model in private or limited access past the deadline, launch it under a different Claude name that does not satisfy the rule, or decide that the leaked system is not ready for public release yet. The market is effectively pricing disagreement over whether the leak and early-access testing will translate into a publicly usable product fast enough to meet the June 15 cutoff.
The biggest price moves would likely come from Anthropic making an official announcement, opening public signups, or publishing product documentation that clearly identifies Claude Mythos or confirms the leaked model’s identity. A launch under another Claude label such as Haiku, Sonnet, or Opus would matter only if Anthropic or credible reporting ties it directly back to the leaked Mythos system. Conversely, signals that the model is staying in closed beta, that access remains invite-only, or that the company is focusing on other Claude releases instead would push the market toward No.

View marketThe current market price implies roughly a 22% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
Readers should check the exact release form, because the rules require public accessibility and do not count private access, closed beta, or internal testing. The key source of truth is whether Anthropic itself, or a consensus of credible reporting, confirms that the released product is Claude Mythos or the same model from the leak. The deadline is June 15, 2026 at 00:00 UTC, so any public launch after that timestamp would not qualify even if it happens shortly afterward.

This market is currently listed with an end date of Jun 15, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
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.
