Jon Wertheim has reignited the debate over tennis’ long-standing betting integrity issues, directly challenging the ATP and WTA to adopt stricter measures akin to those recently implemented by the NBA. The tennis governing bodies have faced mounting criticism after a series of match-fixing scandals, particularly among lower-ranked players, with convicted fixers often holding rankings below 1,000.
Wertheim’s call to restrict microbets and betting on challenger-level tournaments below mirrors the NBA’s recent crackdown, which now limits wagers on low-minute players and first-basket scoring. The NBA’s move also includes expanded player training led by former NFL star Charles Tillman and updated conduct rules to combat betting-related harassment, reflecting Commissioner Adam Silver’s push to safeguard league integrity amid the rise of sports betting.
While the ATP and WTA have announced new rules for 2027—requiring betting partners to contribute 10% of sponsorship funds toward player welfare—they have yet to match the NBA’s proactive stance on betting restrictions, leaving tennis’ integrity under scrutiny as betting sponsorships grow.
