Resolution criteria

• Resolves to the nation officially listed as the gold medalist in the Mixed 4x400m relay final at the World Athletics Championships, Tokyo 2025, on the World Athletics results page for that competition (navigate to “4x400 Metres Relay — Mixed — Final”). The final is scheduled for Saturday, 13 September 2025 at 22:20 JST. World Athletics listing is the sole source. If World Athletics revises the medal order within 48 hours of the final, the market follows the revision; later changes are ignored. If the final is not contested at Tokyo 2025, resolves N/A.

Background

Considerations

• Teams can change running order and personnel between heats and final; star athletes may be rested for heats. (worldathletics.org)

• Disqualifications for baton/exchange or lane infringements are not rare in relays and can alter podiums shortly after the race; this market follows the official listing within 48 hours. (worldathletics.org)

• The mixed relay’s outcome can hinge on tactical order (M/W/M/W or variations) and anchor-leg strength (e.g., Netherlands with Femke Bol at recent majors). (worldathletics.org)
