Five Big Ten states still have no statewide sportsbook app this fall. Here is where every state stands.

The Big Ten now runs from New Jersey to Los Angeles, and the legal map under it is as uneven as the conference. Eight of its 14 states have full online sportsbook markets. The other six do not, and two of the biggest fights over prediction markets in the country are happening inside the footprint. Here is where each state stands heading into the second half of the season.

California: nothing until 2028 at the earliest

UCLA and USC play in the largest state without legal sports betting of any kind. Changing that takes a constitutional amendment approved by voters, and both 2022 measures lost badly. The state's gaming tribes have said there will be nothing on the ballot this year and are working toward 2028. Prediction markets, Novig among them, are available statewide. A September Ninth Circuit ruling found that Kalshi's sports contracts are likely unauthorized gaming on tribal land, but that ruling covers tribal land, not the rest of the state. California page

Minnesota: no sportsbook, and a prediction-market ban on hold

Minnesota's 2026 sports betting bill never got out of committee. The Legislature instead passed a law making it a felony to run a prediction market in the state from August 1. A federal judge blocked it on July 27, finding it likely preempted by federal commodities law, so Gophers fans can still use Novig, Kalshi and Polymarket US while the case goes on. Minnesota page

Wisconsin: the law is signed, the apps are not live

Gov. Tony Evers signed Assembly Bill 601 on April 9, allowing statewide mobile betting run by the tribes, with servers on tribal land. Before anything launches, each tribe has to amend its compact and win federal sign-off, and most estimates point to 2027. Today Badgers fans can wager only inside a tribal casino. The attorney general has also sued Kalshi, Polymarket and others in state court over their sports contracts. Wisconsin page

Washington: casino property only, and Huskies games are new

Washington's sportsbooks live inside tribal casinos, and their apps stop working at the parking lot. A law that took effect June 11 lets those books take wagers on Washington college teams for the first time, though not player props on in-state college athletes. Washington is also one of the toughest states on prediction markets: its Gambling Commission says event contracts are not authorized there, and a King County judge ordered Kalshi to block most of its Washington contracts this summer.

Nebraska: casino floors, and not for the Huskers at home

Nebraska allows sports betting only in person at its racetrack casinos. A proposed amendment to let voters add mobile betting this year stalled, and state law keeps Nebraska college teams playing in the state off those boards. Prediction markets are available statewide. Nebraska page

Oregon: one app, no college games

Oregon has a single legal online sportsbook, DraftKings, run through the Oregon Lottery. The Lottery has never offered college sports on it, so a Ducks fan in Eugene cannot find their own team on the state's only app. On Novig, they can. Oregon page

Michigan: open sportsbooks, no Novig

Michigan has had a full online market since January 2021, and every major app operates there. It is also the one Big Ten state where Novig is not available. Other prediction markets are restricted too: an Ingham County judge ordered Kalshi in June to stop offering sports contracts in Michigan while the attorney general's lawsuit proceeds.

Ohio, Illinois, Maryland and New Jersey: open, and in court

These four have full sportsbook markets and active fights with prediction markets.

• Ohio: the Casino Control Commission moved to fine Kalshi $5 million in April, and on September 25 the Sixth Circuit ruled that Ohio can apply its gambling laws to Kalshi's sports contracts. Ohio page
• Illinois: a 2026 budget law added a state license and tax for prediction markets, and Kalshi and the CFTC have sued to block it. Illinois sportsbooks also cannot take wagers on Illinois college teams, so Illini and Northwestern fans find their own games only on prediction markets. Illinois page
• Maryland: Kalshi lost its bid to block the state's cease-and-desist order in federal district court, and its appeal is pending at the Fourth Circuit. Maryland page
• New Jersey: the Third Circuit sided with Kalshi in April, and the state has asked the U.S. Supreme Court to take the case. New Jersey's constitution still bars wagers on its own college teams, so Rutgers games are off every New Jersey sportsbook. New Jersey page

Novig is available in all four. Polymarket US currently does not serve any of them.

Indiana, Iowa and Pennsylvania: the straight comparison

Hoosiers, Boilermakers, Hawkeyes and Nittany Lions fans have both full sportsbook markets and every major prediction market, with no active state fight. Every board in those states shows the whole comparison side by side. Indiana · Iowa · Pennsylvania

Each state page carries the date it was last reviewed. We recheck them monthly and after any ruling or vote, and in Ohio, Washington and Minnesota that could come any week.
