Player props were the fastest-growing bet type in US sports betting right up until they became the center of the industry's biggest integrity crisis. Over the past year, a string of federal gambling investigations touching the NBA and MLB has forced leagues, regulators and sportsbooks into an uneasy renegotiation of what prop markets should even be allowed to exist.
How the crisis started
The NBA's reckoning traces back to Jontay Porter, who received a lifetime ban after an investigation found he had disclosed confidential information to bettors and deliberately limited his own on-court participation to influence prop outcomes. That case led federal investigators to a much wider network, and in October 2025 prosecutors charged current and former NBA figures - including a current player and a head coach - with conspiracy tied to alleged insider-information betting schemes and, separately, an illegal poker operation. One case at the center of the indictments involved a player allegedly signaling in advance that he would limit his playing time, allowing associates to bet on his statistical unders before the information became public.
Baseball had its own version. Federal indictments against pitchers accused of manipulating in-game outcomes tied to microbetting markets - wagers on individual pitches - pushed MLB to act on a different front of the same underlying problem: bet types granular enough that a single player, acting alone, could plausibly influence the outcome.
What leagues and sportsbooks changed
The response has moved fast relative to how slowly sports betting regulation usually changes:
- Injury reporting overhaul: The NBA now requires teams to resubmit injury status reports in a tighter daily window and refresh public listings every 15 minutes, aimed at closing the gap where nonpublic availability information could leak to bettors before the public report catches up.
- Prop bets pulled from fringe roster players: Major sportsbooks agreed to stop offering player props on athletes on two-way or 10-day contracts, where a single limited-role player is both easier to influence and easier to bet on with less market scrutiny.
- Microbetting limits in baseball: MLB worked with sportsbooks and regulators to cap next-pitch and similar hyper-granular live markets, and to prohibit those bet types from being combined into parlays, where a single manipulated pitch could pay out disproportionately.
- Congressional attention: The Senate Commerce Committee formally requested information from the NBA about how it investigated the allegations and what safeguards it has in place, while a member of the House has pushed letters to multiple leagues urging support for federal integrity standards rather than a state-by-state patchwork.
The prop ban that isn't happening
Despite the scale of the scandals, a blanket ban on player props looks unlikely. Player props are one of the most profitable and heavily bet product categories at every major sportsbook, and outright eliminating them would be a significant revenue hit the industry has shown little appetite for. Instead, the emerging consensus among leagues and regulators favors narrower guardrails: fewer markets on low-profile players, tighter limits on live microbetting, and faster information-sharing between sportsbooks and leagues when unusual betting patterns show up.
Roughly 17 states already restrict some form of college player prop betting, and full-blown prohibition already exists in a handful of states like Louisiana - suggesting the more likely national outcome is a patchwork of narrower restrictions rather than a single federal standard.
What it means for bettors
For most recreational bettors, the visible impact has been a modest thinning of prop menus, particularly around bench and rotational players in the NBA, and tighter limits or removal of certain live in-game markets. Sportsbooks have also become faster to flag and limit accounts showing unusual betting patterns on niche props, a practice that predates the recent scandals but has intensified alongside them. The bigger structural questions - whether leagues should get direct approval rights over which bet types sportsbooks can offer on their games, and whether that requires federal legislation rather than voluntary agreements - remain unresolved heading into the 2026-27 season.
Frequently Asked Questions
Because they can be more vulnerable to integrity risks, especially in niche markets where a small event can decide the outcome.
No. The trend described in the article is tightening and rethinking, not a universal ban across all operators and jurisdictions.
More conservative menus, extra restrictions on obscure props, and closer monitoring of unusual betting activity.
