Sports Betting Laws in Idaho: Is It Legal in 2025?

TL;DR: Is Sports Betting Legal in Idaho?

No. Sports betting is illegal in Idaho. There are no legal sportsbooks, online betting apps, or licensed operators in the state. Idaho has not passed any laws to legalize sports betting.

Quick Answer: Is Sports Betting Legal in Idaho?

No. Sports betting is fully illegal in Idaho. You cannot legally place a sports wager at a retail location, through a mobile app, or with any licensed operator inside state lines. Idaho has not passed any legislation to legalize sports betting since the U.S. Supreme Court's ruling in Murphy v. NCAA, 584 U.S. 453 (2018). That ruling struck down a federal law and gave states the authority to legalize sports wagering. Idaho has not used that authority.

Idaho's gambling prohibition is in the state constitution (Idaho Constitution, Article III, Section 20), not just in a statute. This means the legislature cannot legalize sports betting by passing a bill alone; voters must first approve a constitutional amendment. This multi-step process has not begun.

As of the 2025 and 2026 legislative sessions, no sports betting bill has been introduced in the Idaho Legislature. Idaho is one of a few states that has made no legislative progress toward sports betting since the Murphy decision.

What is legal in Idaho:

• The Idaho State Lottery (authorized under Idaho Constitution, Article III, Section 20)
• Charitable bingo and raffles (authorized under Idaho Constitution, Article III, Section 20)
• Pari-mutuel horse racing wagering (authorized under Idaho Constitution, Article III, Section 20)
• Tribal gaming under federal compacts (Class II and Class III games at tribal facilities)

Sports wagering does not fit any of these narrow constitutional exceptions.

Idaho Gambling Laws: The Statutory Framework

Idaho's gambling prohibition exists at two levels: the state constitution and the criminal code. Understanding both is essential to grasp why sports betting is not merely unregulated, but affirmatively criminalized.

The Constitutional Foundation

Idaho Constitution, Article III, Section 20 declares that gambling is contrary to public policy and is prohibited, except for specific carved-out activities: a state lottery, pari-mutuel betting on licensed horse racing, and bingo and raffle games conducted by nonprofit organizations. Sports wagering is not among these exceptions. Because the prohibition is constitutional, legislative action alone cannot authorize sports betting; a constitutional amendment is required.

The Criminal Statutes

Idaho Code Title 18, Chapter 38 contains the core criminal gambling provisions.

Idaho Code § 18-3801 defines "gambling" as risking money or other things of value on the outcome of a contest of chance or a future contingent event not under the person's control or influence, where there is an understanding that they will receive something of value in the event of a certain outcome. Sports wagering fits squarely within that definition. The outcome of a football game or baseball matchup is a future contingent event not under the bettor's control.

Idaho Code § 18-3802 establishes the general gambling offense. It prohibits a person from making any bet or wager, participating in gambling, or playing any game of chance for money or other things of value. This statute applies to individual bettors placing sports wagers.

Idaho Code § 18-3803 covers "professional gambling," a more serious offense. It applies to persons who operate, promote, or profit from gambling activity, including running a gambling enterprise, accepting bets from others, or maintaining gambling equipment or premises.

Social Gambling

Idaho law recognizes a narrow exception for casual, social gambling. Idaho Code § 18-3801 distinguishes between gambling conducted for profit and social gambling where participants play on equal terms and no one takes a cut. A friendly poker game among friends where no one is running the house falls into a different category than operating a sportsbook. This distinction does not apply to commercial sports betting, whether with an offshore or other operator.

Penalties for Illegal Sports Betting in Idaho

The consequences differ significantly depending on whether one is the bettor or the operator.

Individual Bettors

Placing a sports wager in Idaho is a misdemeanor under Idaho Code § 18-3802. Under Idaho's general misdemeanor sentencing framework (Idaho Code § 18-111), a misdemeanor carries a maximum jail term of up to one year in a county jail and a fine of up to $1,000. In practice, individual bettors are rarely prosecuted in Idaho, but the legal exposure is real.

Operators and Promoters

Running any form of sports wagering operation in Idaho is a felony under Idaho Code § 18-3803 (professional gambling). Consult the Idaho Attorney General's office or a licensed Idaho criminal defense attorney for current sentencing ranges under that provision, as penalty tiers for felony gambling offenses should be confirmed against the current enrolled statute. The distinction matters: accepting bets from others, maintaining a book, or profiting from others' wagers elevates the offense from a misdemeanor to a felony with substantially greater exposure.

Offshore and Out-of-State Online Sportsbooks

Using an offshore sportsbook or an out-of-state online platform while physically located in Idaho exposes you to prosecution under Idaho Code § 18-3802. The bet is placed in Idaho, regardless of where the server sits. Idaho law enforcement has not historically prioritized prosecuting individual recreational bettors using offshore sites, but the legal risk is not zero, and it increases if amounts are large or activity is frequent. There is no licensed, legal online sportsbook that accepts Idaho residents.
