Why Prop Bets Are the Riskiest Bet in Sports

A single pitch, bought and sold

In November 2025, the U.S. Attorney's Office for the Eastern District of New York unsealed an indictment against two Cleveland Guardians pitchers, Emmanuel Clase and Luis L. Ortiz, alleging they conspired with bettors to intentionally throw specific pitches so co-conspirators could cash prop bets on them. Both pitchers have pleaded not guilty, and they are presumed innocent unless proven otherwise. But the allegations, laid out by the Department of Justice, describe exactly why one category of bet worries regulators and clinicians more than any other.

According to the indictment, the scheme did not require anyone to lose a game or shave points. It required one pitch to be a ball instead of a strike, or to come in slower than a set velocity. Prosecutors allege bettors made roughly $27,000 on a single pitch clocked faster than a threshold in one instance and tens of thousands more on individual slow pitches, with the pitchers' alleged conduct generating at least $400,000 in rigged bets.

That is the tell. A bet that can be decided by one person, on one moment that does not change who takes the game, is a bet that can be bought. And a bet that can be bought that easily is a bet designed to fire your brain's reward system over and over, on a loop, with no natural stopping point.

What MLB did, and what it admitted

On November 10, 2025, MLB and its authorized sportsbooks announced that operators representing more than 98% of the U.S. betting market would cap pitch-level prop bets at $200 and exclude them from parlays, effective immediately.

The league's own explanation is worth reading closely. MLB said pitch-level bets "present heightened integrity risks because they focus on one-off events that can be determined by a single player and can be inconsequential to the outcome of the game." Translate that out of press-release language: these bets don't measure whether a team competes well. They measure a single, isolated action that one person controls. That's what makes them riggable. It is also what makes them the purest form of compulsive action a sportsbook can sell.

The 2026 split: Ohio versus Colorado

The Guardians case landed in the middle of a national argument, and 2026 has pulled state governments in opposite directions.

In Ohio, a group of Republican lawmakers introduced House Bill 971, the "Save Ohio Sports Act," in early July 2026. As reported by Bettors Insider and covered widely across the industry, the bill would eliminate online sports betting statewide, confine wagering to the state's four casinos and their retail sportsbooks, cap individual bets at $100, limit bettors to eight wagers in any 24-hour period, and prohibit parlays, in-game live betting, and player prop bets entirely. If it passed, Ohio would be the first state to repeal legal online sports betting since the 2018 Supreme Court decision that opened the door to it. The bill has not yet been assigned to a committee and faces a long road.

Colorado went the other way. On April 21, 2026, the state Senate Appropriations Committee voted 5-2 to strip a proposed prop-bet ban out of Senate Bill 131. As Colorado Public Radio reported, sportsbooks warned that banning prop bets would cost the state millions in tax revenue during a budget deficit, with much of that money earmarked for water projects. A fiscal estimate put the cost of a prop-bet ban at about $2.4 million in lost revenue; removing the ban dropped the projected cost to roughly $800,000. The bill moved forward with other consumer protections intact, including limits on push notifications and a ban on marketing terms like "no sweat."

That contrast is the whole story. Ohio's bill treats props as a public-health problem. Colorado's outcome treats them as a revenue line. The product didn't change. The politics did.

College sports drew the earliest line

The clearest consensus so far is around college athletes. According to Birches Health, 17 states now ban college player prop bets entirely, and additional states allow them only with restrictions. The NCAA has pushed hard for this: President Charlie Baker has urged state commissions to eliminate the bets, and the NCAA reports that 36% of Division I men's basketball players have experienced harassment from bettors, noting that "player prop bets attach an individual student-athlete's name to a bet."

A complete national ban on props for professional sports remains unlikely. Massachusetts lawmakers have advanced a "Bettor Health Act" that would prohibit prop and in-play bets and raise the state betting tax to 51%, but sweeping national restriction is not on the table. The realistic near-term fight is over caps, parlay exclusions, college carve-outs, and how aggressively apps are allowed to push notifications at you.

Why props and micro bets are built to hook you

Here is the part that matters for recovery, and it's the same reason these bets are easy to rig.

A traditional bet on who takes the game gives you one outcome, hours away. A player prop or a pitch-by-pitch micro bet gives you a fresh outcome every few seconds. That difference is not a convenience. It's a mechanism.

Three things make continuous, in-play props uniquely dangerous:

Continuous action. Gambling disorder (ICD-10 code F63.0, DSM-5 312.31) escalates fastest with products that never make you stop and wait. Micro props remove the pause. There's always a next pitch, a next possession, a next serve. A review cited by the National Library of Medicine notes that microbetting "allows constant and impulsive betting, possibly augmenting the risk for gambling disorder."

Intermittent reinforcement. Unpredictable, frequent payouts train the brain harder than steady ones. It's the same schedule that makes slot machines sticky. Micro props deliver dozens of small, unpredictable hits per game, and researchers have compared the resulting dopamine cycles directly to slots.

Loss-chasing at speed. When a bet doesn't land, the next opportunity is already on the screen. That's the engine of chasing losses: the temptation to recover what you just lost with one more small bet, right now, before the moment passes. Speed turns a bad night into a spiral.

We've written about these mechanics before, because they aren't unique to baseball. See microbetting and addiction, why sports betting is so addictive, and how gambling apps are built to keep you coming back.

What this means if you're struggling

The lesson of the Guardians case isn't only about integrity. It's a diagnosis of the product. If a bet can be decided by one person on one meaningless moment, it was built for volume, not for sport. And volume is exactly what compulsive gambling runs on.

You don't have to wait for a law to protect you. If you notice that props and in-play betting are where the trouble lives for you, that isn't a character flaw. It's the product working as designed. The move is to close the loop the product depends on: no next pitch, no next bet.

Concrete next steps:
