College Football Prop Betting Age By State

The Age, State by State

Thirty-three states with a legal market set the floor at 21 outright, no asterisk attached. Four still run it at 18: Montana, New Hampshire, Rhode Island, and Wyoming. Washington’s row carries an asterisk because the age that applies there depends on whether the casino serves alcohol. Eleven states show n/a because none of them has legalized sports betting of any kind yet, college props included, so there’s no age to clear because there’s no menu to clear it against. A few of those eleven have floated an age in a bill that never passed, 21 shows up most often in that pile, but a proposed floor in a dead bill isn’t a live rule, and none of it belongs in the same column as a state that has a market open.

The 18-Year-Old States

Four states let an 18-year-old bet college football props right now, and each one runs a different version of what that floor buys.

The District of Columbia sets its floor at 18 as well, under the Sports Wagering Lottery Amendment Act of 2018. As a district it sits outside the state table above, and two caveats there matter more than the age does. BetMGM and Caesars both card at 21 in the District as house policy, so a legal floor of 18 still leaves an 18-year-old turned away at some of the biggest apps. Bovada blocks the District outright, which closes the offshore route other under-21 readers fall back on.

New Hampshire hands the entire market to a single operator. DraftKings holds an exclusive license through the state lottery running to 2028, online and retail both, and the 18 floor covers that one app and its five retail counters alike.

Montana’s 18 comes with a catch the other three states don’t share. Sports Bet Montana, the state lottery’s kiosk-and-app network, only accepts a wager while the bettor is physically on-site at one of the hundreds of licensed bars, taverns, casinos, and restaurants carrying it. A bet slip builds anywhere on a phone. Placing it still means standing inside one of those specific locations, since simply being somewhere in Montana never clears that bar on its own.

Rhode Island’s 18-year-olds have one option too. Sportsbook Rhode Island, the IGT-run app operating under the state lottery, covers the whole online market, plus retail counters at Bally’s Twin River and Tiverton properties. A second license went to Bally Bet back in May 2026, but it can’t launch before Nov. 26, 2026, when the current operator’s exclusivity runs out, so the one app is the whole picture for now.

Wyoming’s the outlier among the four, running a full multi-operator market at 18. DraftKings, FanDuel, BetMGM, Caesars, and Fanatics all took the state online back in September 2021, and a retail sportsbook operates on the Wind River Reservation under the Northern Arapaho Tribe’s compact, the only tribal book in the country still carrying the same 18 as its state’s commercial market.

Kentucky’s 2026 Change

Kentucky spent three years as the outlier, letting 18-year-olds bet sports, college football props included, a holdover from the same tradition that lets 18-year-olds bet the horses at Churchill Downs. That ended in 2026. HB 904, the Wagering Consumer Protection Act, raised the floor from 18 to 21 across every operator in the state, DraftKings, FanDuel, BetMGM, Caesars, bet365, Fanatics, theScore Bet, Circa Sports, and Prime Sports alike. Gov. Andy Beshear vetoed the bill, and the legislature overrode that veto on April 14, 2026. The new floor took effect July 15, 2026.

What happens to three years’ worth of 18-, 19-, and 20-year-old customers those operators built up is the open question. Kentucky’s regulator, the Kentucky Horse Racing and Gaming Corporation, has confirmed those accounts stop working under the new floor. Neither the regulator nor the operators have published whether a frozen balance gets returned automatically or has to be requested. Not published means exactly that. There’s no figure to print here, and an invented one would be worse than none at all. Kentucky’s the clearest reason every figure above carries a date instead of getting treated as permanent.

Age at Tribal and Retail Books

The number on a state’s law and the number posted at the door don’t always match, and the gap runs both directions.

Washington’s the sharpest example. State law sets 18 as the floor wherever a tribal sportsbook serves no alcohol, but the large majority of Washington’s roughly 19 compact-run books sit on casino floors that do, so 21 is the practical number almost everywhere in the state. The property’s own posted age at the entrance is what actually governs a visit, not the statute on a website.

Montana runs the opposite split. Its 18 floor belongs entirely to Sports Bet Montana, the state lottery’s network of bars, taverns, and kiosks. Montana’s tribal casinos sit outside that network altogether and don’t carry sports wagering under it, so there’s no 18-versus-21 question at a Montana tribal property the way there is in Washington, because there’s no sportsbook there to card anyone at.

Wyoming’s tribal book, the Buffalo Sportsbook at Wind River Hotel & Casino, runs under the Northern Arapaho Tribe’s own compact and still lands on the same 18 as the state’s online market. No separate tribal figure has surfaced for it.

Kentucky has no tribal gaming at all. Its retail books sit at pari-mutuel tracks instead. Churchill Downs, The Red Mile, and The Mint Gaming Hall at Kentucky Downs all count among them. Every one of those counters now checks for 21, the same as the state’s apps, since HB 904 took hold.

Rhode Island’s retail counters at Bally’s Twin River and Tiverton run under the same state-lottery framework as the Sportsbook Rhode Island app, so no separate number applies there either. Where a gap exists, it traces back to a specific compact or statute, not a rule of thumb, and the surest way to know which number applies to a given property is the age posted at that property’s own front door.

Age at the Offshore Books

Bovada and BetOnline both set 18 as their own floor, MyBookie draws its line three years higher at 21, and none of those numbers has anything to do with what a state itself has set. A 19-year-old locked out of a state’s own 21-and-up app can still open a Bovada or BetOnline account the same afternoon, because each book runs its own ID-based gate rather than checking a state’s date-of-birth requirement. Bovada’s terms spell out the consequence for getting that gate wrong: an account opened by someone under 18 gets closed and any winnings inside it are forfeited. MyBookie sets that same 21 floor just as flatly in its own rules, though without spelling out Bovada’s forfeiture language. The paperwork behind each gate is a separate fact to weigh before funding an account. Panama holds BetOnline’s license. A Curaçao-linked framework holds MyBookie’s. The Union of the Comoros holds Bovada’s, and a US state gaming board isn’t part of the picture at any of the three. The full rundown of every sportsbook covering college football props breaks down what else separates the three.
