Following the controversial disqualification of Andrey Rublev from the 2024 Dubai Championships, there have been outcries of phasing out linesperson in favour of electronic line calling.

This market will be resolved to YES if, in an entire season (2025, 26, 27, or 28), all matches played at the ATP tour level use electronic line calling, this includes matches on non-centre courts and doubles matches but does not include qualification rounds. Challenger events, and ITF tournaments (such as the Davis Cup) are not counted.

The market will resolve to NO if the above criteria are not met.

In case of controversy regarding market definition such as new line calling methods, I will make my best effort to disambiguate, but if that proves impossible the market will be resolved to N/A.
