Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi markets share identical resolution criteria, focusing on the official UFC Welterweight Champion as of December 31, 2026, at 12:00 PM ET, excluding interim champions.Primary resolution logic: Official UFC website (https://www.ufc.com/athletes)Core resolution logic:
- Resolution is determined by the official UFC Welterweight Champion on December 31, 2026, at 12:00 PM ET.
- Interim champions are not considered valid for resolution; only the undisputed champion counts.
- If the Welterweight title is vacant at the resolution time, the market resolves to 'Other'.
Edge cases & clarifications:
- Vacant Title: If the UFC Welterweight title is vacant on December 31, 2026, at 12:00 PM ET, all markets related to specific fighters will resolve to 'Other'.
- Fighter Changes Weight Class: If a fighter listed in a market changes weight class before December 31, 2026, and is no longer a Welterweight, the market will still resolve based on whether they are the Welterweight champion at the specified date and time. Their change in weight class does not invalidate the market.
Polymarket
This market will resolve according to the official UFC Welterweight division champion on December 31, 2026 at 12:00 PM ET. Only official UFC division champions will count. Interim champions will not count. If the relevant belt is vacant at this market’s check time, or there is otherwise no champion in the specified division, this market will resolve to “Other”. The primary resolution source for this market will be official information from the UFC (https://www.ufc.com/athletes).
Kalshi
These markets resolve based on which fighter holds the UFC Welterweight Title on December 31, 2026, at 12:00 PM ET. Each market is dedicated to a specific fighter, and the outcome is determined solely by whether that individual is the reigning champion at the specified time. All markets explicitly state that they are not endorsed by the UFC or Zuffa LLC, and any references to the UFC are purely descriptive. The markets also clarify that the platform operating them, Kalshi, has no official affiliation with the UFC or any governing body related to the sport. Trademarks and brand names mentioned are the property of their respective owners, and the markets serve an informational purpose regarding potential championship outcomes rather than any official betting or endorsement capacity.
