Can I bet on college football in Oregon?

Not through the state's licensed sportsbook. Oregon is the only state that prohibits wagering on all college sports, in-state and out, team markets and player markets alike. The Oregon Lottery's sole mobile operator cannot offer them. College football and college basketball event contracts on Kalshi and Polymarket are not offered under an Oregon licence and are not covered by that prohibition.

Has the Oregon Lottery taken action against Kalshi or Polymarket?

No. As of August 19, 2026 there is no cease-and-desist letter, no lawsuit and no public enforcement action from the Oregon Lottery, the Oregon Racing Commission or the Oregon Department of Justice against any prediction market operator.

Does the Washington ruling apply to Oregon?

No. The August 14, 2026 King County Superior Court order requiring Kalshi to shut six market categories is a Washington state court order and binds conduct in Washington. It has no direct effect in Oregon, and Oregon residents saw no change in market availability after it issued.

Why does the Ninth Circuit matter to Oregon?

Oregon sits in the Ninth Circuit, alongside Nevada, Washington, Arizona, Montana, Idaho, California, Alaska and Hawaii. Nevada's federal district court sided with state regulators on whether sports event contracts are exempt from state gambling law; Tennessee's court, in the Sixth Circuit, went the other way. Whichever way the Ninth Circuit resolves that question will govern Oregon without Oregon having to file anything.

Is Kalshi legal in Oregon? The only state where the gap is a rule, not a lawsuit

Explainer · Updated August 19, 2026 · 18+ · Not legal advice · By BetG8 Editorial · Prediction Markets

Oregon is the only state in the country where a licensed sportsbook cannot legally take a bet on the University of Oregon Ducks. Kalshi and Polymarket can, and do. That one sentence is the whole Oregon story, and it makes Oregon different from every other state we have written up. Everywhere else, the prediction-market argument is about whether residents may trade at all. In Oregon it is about what they may trade — and the category in dispute is one the state's own operator is barred from touching.

Short answer: Yes, in practice. Kalshi and Polymarket US both hold Commodity Futures Trading Commission designated-contract-market licences and both accept Oregon residents. Neither the Oregon Lottery nor the Oregon Department of Justice has issued a cease-and-desist letter, filed suit, or taken any public enforcement action against a prediction market as of August 19, 2026. Oregon is a no-action state — which is not the same as an approving state.

Aug 14, 2026	A King County judge orders Kalshi to shut six market categories in Washington. The order stops at the Columbia River.
Aug 19, 2026	No Oregon Lottery or Oregon DOJ action on record. College event contracts remain available to Oregon residents.

The gap only Oregon has

Oregon prohibits wagering on all college sports — every game, every team, every player, in-state and out of state. No other state does this. The reason is not integrity policy. It is accounting: Oregon Lottery proceeds fund state programmes including higher education, and the legislature judged that taking bets on the same universities the money supports was a conflict it did not want on the books. A bill, SB 1503, would loosen the rule by letting the Lottery offer wagers on college games while keeping college player props off the board. It has not become law.

Kalshi and Polymarket do not operate under that rule. Their college football and college basketball event contracts are listed under a CFTC designation, not an Oregon Lottery contract, and Oregon residents price and trade them on the same autumn Saturdays the state's own licensed sportsbook has to sit out.

That inverts the argument every other state has been making. Elsewhere the complaint is that event contracts duplicate a product the state already licenses and taxes, and siphon handle out of it. In Oregon, on college markets, there is no product to duplicate. The state did not lose tax revenue when an Oregon resident traded a Ducks contract on Kalshi, because Oregon was never going to collect any tax on that wager in the first place.

Why Oregon has not acted

Three reasons, and only the third is about law.

No licensee is being undercut on the disputed category. The states that moved fastest — Nevada, New Jersey, Ohio, Maryland, Tennessee — all host commercial sportsbook licensees who paid for market access and complained loudly when an unlicensed venue started quoting the same games. Oregon's single operator works under a Lottery contract, and on college markets it has no position to defend, because it is not permitted to hold one.

Oregon regulates sports wagering through a revenue agency, not a gaming commission. Nevada has a Gaming Control Board; Tennessee has a Sports Wagering Council; Ohio has a Casino Control Commission. Each is an independent regulator with a standing enforcement docket and its own cease-and-desist power. Oregon has a lottery. That is a structurally slower path to a demand letter, regardless of what anyone in Salem thinks about prediction markets.

The answer is likely to arrive from outside Oregon anyway. Oregon sits in the Ninth Circuit, alongside Nevada, Washington, Arizona, Montana, Idaho, California, Alaska and Hawaii. Nevada's federal district court sided with state regulators on whether sports event contracts escape state gambling law. Tennessee's federal court, in the Sixth Circuit, went the opposite way on February 19, 2026, when Judge Aleta Trauger held that Kalshi is likely to succeed in showing its contracts are “swaps” under the Commodity Exchange Act and that Tennessee's scheme is likely preempted. That is a real circuit split forming. Whichever way the Ninth Circuit resolves it will bind Oregon, and Oregon does not have to file a single page to receive that ruling. Salem can wait. So far it has.

Where Oregon sits on the national map

Posture	States	Oregon?
Court-ordered restriction in force	Nevada, Washington	No
State suing or actively enforcing	New York, Maryland, Arizona, Connecticut, Massachusetts	No
Kalshi protected by an injunction	Tennessee, Minnesota, New Jersey	No
No public state action on record	Oregon and most of the remaining map	Yes

What would change this

Three things, in rough order of likelihood.

One: SB 1503 or a successor passes. The moment Oregon's licensed operator can legally take an Oregon Ducks bet under a Lottery contract, and Kalshi can take the same trade with no Oregon licence and no Oregon tax, Oregon acquires exactly the grievance that produced cease-and-desist letters in a dozen other states. This is the sharpest thing to understand about Oregon: the reform that would legalise college betting in the state is also the single most likely trigger for Oregon's first fight with Kalshi. The catalyst here is a bill, not a lawsuit.

Two: the Ninth Circuit rules. Oregon inherits the answer without acting.

Three: the CFTC narrows the product federally. The Commission has proposed rules limiting sports event contracts, its enforcement division has issued a prediction-markets advisory, and it is running an internal review of “mention markets” that has already caused Kalshi to pull some listings voluntarily. Federal narrowing shrinks the Oregon gap without Oregon lifting a finger.

Until one of those three lands, the position holds: available, unlicensed, untaxed, and unchallenged.
