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 city officially announced by FIFA as the host of the final of the 2030 FIFA World Cup, currently scheduled for July 21, 2030. A qualifying announcement means an official confirmation by FIFA of the stadium or city selected to host the final. Bid proposals, venue lists, recommendations by member federations or bid committees, and media speculation about FIFA's decision will not qualify on their own. If FIFA announces a stadium rather than a city, this market will resolve to the city FIFA designates as that stadium's host city in its official 2030 FIFA World Cup materials. A qualifying announcement before this market's close date will immediately resolve this market to the corresponding option, regardless of any subsequent change to the venue or to the scheduled date of the final. If no host city for the final is officially announced by December 31, 2027, 11:59 PM ET, this market will resolve to "Other". The primary resolution source for this market will be official information from FIFAShow the full rules text

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.
