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 according to the company that owns the model that has the highest arena rank among primarily Chinese companies, based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on August 31, 2026, 12:00 PM ET. Chinese Companies include but are not limited to Alibaba, Moonshot, Baidu, Z.ai, Xiaomi, DeepSeek, Bytedance, MiniMax, Meituan, Tencent, and StepFun. Companies not headquartered in China or not primarily owned or operating within the Chinese technology ecosystem are not considered primarily Chinese. Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market. Qualifying Chinese Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Meituan” would be ranked ahead of “Xiaomi”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the arena.ai Text Arena (Overall). If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".Show the full rules textHide the full rules text

Certainty reflects how much of this market we measured, not how good the market is.

No full-provenance CME signal is linked to this condition in the current ledger window; absence of a signal is not proof of coherence.

50+17.9 - ExecutabilityModeled estimatefixed rules, not a per-market measurementweight 20.0
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.
- · executability worse of spread depth
- · spread: top-of-book spread 0.8c

100+7.1
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.
