NBA Commissioner Adam Silver has long been one of the most vocal advocates for legalized sports betting in the United States. Yet now, after years of rapid market growth, he believes the time has come for tighter regulation and clearer national standards.

Speaking on The Pat McAfee Show, Silver said he accepts that betting has become part of modern sports, but warned that fragmented oversight creates challenges. “We accept betting is legal… It’s unlikely to go away,” he said. “I think, probably, there should be more regulation, frankly. That may be surprising to hear from me.”
Silver’s comments reflect growing concern over the fast expansion of betting across multiple states without federal coordination. Each state currently determines how betting operates, which Silver believes leaves gaps in monitoring and enforcement. His priority, he explained, is to “protect competitors” and maintain integrity inside the arenas.
The NBA has already taken voluntary steps. Some league partners were asked to reduce prop bet offerings—especially on players with two-way contracts. According to Silver, these smaller markets create risk because “it’s too easy to manipulate something which seems otherwise small and inconsequential to the overall score.”
Last year, Silver handed down one of the harshest penalties in modern sports history. Former Toronto Raptors forward Jontay Porter was banned for life after conspiring with bettors to influence his game participation. Porter reportedly faked or exaggerated injuries to exit two contests early, triggering profitable outcomes for those who wagered against him.
Silver said the case highlighted the importance of close collaboration between leagues and betting operators. He said:
“We’re trying to put in place and learning as we go, and working with the betting companies, some additional control, to prevent some of that manipulation.”
The NBA, like most major leagues, now relies on specialized integrity firms such as IC360 and U.S. Integrity to detect suspicious activity. These companies analyze betting data from sportsbooks and alert leagues when patterns suggest potential tampering or insider involvement.
“With this regulated structure of legalized betting, we can monitor it in ways that were unimaginable years ago,” Silver said, adding that while challenges remain, the regulated environment is far safer than the old underground markets.
Silver believes the fragmented state-by-state system leaves gaps in oversight. He supports a more unified approach that strengthens integrity monitoring and limits riskier forms of betting.
Prop bets involve wagering on specific player actions rather than game outcomes—like points scored or rebounds. Silver says these are vulnerable to manipulation, especially for players on smaller contracts or limited minutes.
The league works with integrity partners such as IC360 and U.S. Integrity, which track betting data from sportsbooks nationwide. They flag unusual patterns for further review.
Yes. Silver remains a supporter but insists the industry must evolve responsibly through better regulation, transparency, and accountability.
The scandal reinforced the need for better data monitoring and cooperation between leagues and sportsbooks to prevent insider manipulation and protect fair play.
