Certainty reflects how much of this market we measured, not how good the market is.
Too much of the trading came from wallets we cannot yet identify, so participant-flow coverage is uncertain.
Use only as a review target. Current-card issues must clear before this price is used as evidence.
The diligence packet carries the memo language, audit chain, and the Markdown, PDF, and JSON exports for this market.

Resolution rules
Rules as stated by Polymarket, reproduced verbatim. Convexly has not independently reviewed them and does not endorse them; the rating's resolution-reliability pillar treats rule text as present but not independently reviewed.
On June 9, 2026, Anthropic released the Mythos-class model Claude Fable 5. This market will resolve to "Yes" if Anthropic releases the next Mythos-class model and makes it available to the general public by the listed date (ET). Otherwise, this market will resolve to "No." Any model whose official name includes “Mythos,” or that Anthropic officially describes as a “Mythos-class” model or similar, will qualify for this market’s resolution. 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.
Experimental rating caveat

Market Trust is a canary preview: verdict cutpoints are operator-set, and each read is a dated, descriptive diagnostic of market quality, not a prediction of the outcome and not a claim about what the probability should be. A prospective calibration test is filed and matures on resolved outcomes.

Boundary of this page
This daily read is market diligence, not investment advice, not a claim of absolute truth, and not proof that any trader should buy or sell. It answers whether this market price had enough substrate to cite, monitor, discount, or ignore at the as-of timestamp, with receipts attached in the diligence packet.
Executability scored as worse-of(spread, depth) from a single orderbook snapshot; the two were merged from the former liquidity + depth pillars to stop double-counting one correlated source.
Resolution source and rule text are present but not independently reviewed.
Participant flow inputs exist but do not meet identity-coverage floors; descriptive only.
One or more screen indicators flagged at a low level. A reason to look, not a finding about anyone.
3 linked artifacts; 0 missing hashes; 0 stale/failing sources.
How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 70.0.
Caveat: 2 pillars not assessed yet; the score will recompute as the substrate fills in.
