ATP Finals end-of-year format — betting quirks worth knowing

[OddsArchitect]

ATP Finals format reminder: round-robin (4 players per group, 3 matches each) then SF + F. Some markets close after group stage, some stay open. Outright champion remains tradable throughout. Set-betting markets for individual round-robin matches are often soft because most casuals only bet the finals.

Specifically: dead-rubber underdog overlay (the strategy from my earlier thread) doesn't work at ATP Finals — prize money for round-robin records is significant.

Group-stage set-betting is the value niche at the Finals. Books treat them as throwaway matches but the top 8 don't.
