The NCAA opened investigations into roughly 40 student-athletes across 20 schools for potential game manipulation last year. Eleven athletes at 7 schools confirmed to have bet on their own performances or fed insider information to bettors. A federal indictment covered 29 manipulated college basketball games between 2022 and 2025, with players pocketing $10,000 to $30,000 per game to shave points. I spend my life building models to separate signal from noise, and this signal is screaming. Colleges should ban regulated sports betting on their campuses. Full access, partial access, kiosk-in-the-student-union access. All of it.
I know the counterargument. Rook will make it better than anyone. Banning betting on campus is whack-a-mole because students just open DraftKings on their phones from a dorm room. He's right that a campus ban doesn't eliminate the behavior. But that concession doesn't change the math.
The Numbers Don't Need a Narrative
The University of Mississippi survey from March found that 6% of student sports bettors met APA criteria for problem gambling. That's not a rounding error. Apply it to any campus with a few thousand active bettors and you're looking at hundreds of students in clinical trouble. Ohio's own 2022 data showed 1 in 5 residents qualifying as at-risk gamblers, and state hotline calls surged in 2023 after legalization. The dose-response relationship here is straightforward: more access correlates with more harm.
Think of it like expected points added in football. EPA doesn't tell you what happened on one play. It tells you the average value of a decision across thousands of plays. A campus betting ban is a negative-EPA play for the gambling industry and a positive-EPA play for student welfare, averaged across the population. Yes, some students will find workarounds. The question isn't whether a ban stops every bet. The question is whether it reduces the rate of harm at scale. The Mississippi data says yes.
Washington state just advanced a bill letting fans bet on in-state college teams at tribal casinos, arguing it pulls money from offshore books. That logic has a surface appeal. Regulated markets are better than black markets. I buy that for adults in the general population. I don't buy it for 19-year-olds living 200 feet from the athletes whose stat lines they're wagering on.
Player Props Are the Accelerant
More than half of the 39 states with legal sports betting allow individual college player prop bets. Props are the specific mechanism through which manipulation happens. A player doesn't need to lose a game to cash a prop bet. He just needs to underperform one stat category. The 11 confirmed NCAA cases were overwhelmingly tied to props. Louisiana, Maryland, Ohio, and Vermont banned college props since 2024. Good. But prop bans without campus access restrictions leave the pipeline intact.
Tennessee's HB 1768 would ban interactive sports betting access on public college campuses and on game days. That's closer to the right idea. Connecticut is prohibiting sportsbook ads at state universities. Massachusetts is capping monthly bets and barring ads during live events. Ohio lawmakers introduced bills to end all sports betting outside casinos and ban wagers on college games entirely. The legislative trend line is clear, and for once it matches the data.
I'll grant that Ole Miss launching the nation's first Center on Collegiate Gambling, with $700,000 in annual funding and 8 certified counselors, is a genuinely good thing. Education and treatment matter. But counseling is a downstream intervention. You don't solve a structural exposure problem with pamphlets.
My model here is simple. When the base rate of harm is 6% among participants, when 29 games were confirmed manipulated over 3 years, when the NCAA itself is begging the CFTC to suspend prediction markets, the expected value of campus access is negative. Not ambiguous. Negative. The variance might produce some semesters where nothing goes wrong at a given school. That's not evidence the policy works. That's small sample noise.
Colleges exist to reduce risk for young people, not to optimize revenue from it. Ban betting on campus. Let the offshore books be someone else's problem.
