NASCAR has announced the formation of an in-season tournament that will take place in 2025 with its new broadcast partners Amazon Prime Video and TNT Sports, and award $1 million to the winner.

The tournament will start with the final three races that air on Prime Video. Those races will determine driver seeding in the head-to-head bracket for the top 32 drivers. The seeding will be established by best finish in each race over the three races, and tiebreakers will be broken by the next-best finish followed by season point position.
