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.
This market will resolve to "Yes" if the listed player clinches a spot in the Quarterfinals at the 2026 US Open per US Open rules. Otherwise, the associated market will resolve to "No". If at any point it becomes impossible for the listed player to clinch a spot in the Quarterfinals at the 2026 US Open (e.g. the player is eliminated), the associated market will resolve to "No". If the 2026 US Open is cancelled, postponed after September 27, 11:59 PM ET, or the players that qualified for the Quarterfinals have not been officially confirmed by the USTA within that timeframe, this market will resolve to "No". The resolution source for this market will be official information from the USTA and WTA; however, a consensus of credible reporting may also be used.
Experimental rating caveat
Market Trust Cards are experimental market-quality diagnostics, not compliance certifications or validated credit ratings.
What travels with this read
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.
No participant flow rollup materialized yet.
No participant concentration rollup materialized yet.
3 linked artifacts; 1 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.
