What's legal
New Mexico has never passed a sports betting law. Betting began on October 16, 2018, at Santa Ana Star Casino Hotel in Bernalillo, which relied on its tribal-state gaming compact. Sports betting counts as Class III gaming, and the compacts already allowed Class III gaming, so no new state law was needed. The minimum gaming age is 21.
You place bets in person at tribal casinos. There are no state-licensed online sportsbooks, and tribal sportsbooks do not offer statewide mobile betting. Tribes regulate their own casinos under the compacts, and the state Gaming Control Board oversees the non-tribal side of gaming.
Crypto and offshore sites
Tribal sportsbooks take bets in person at the casino, so crypto does not come into it. There is no legal route to bet with crypto on sports in New Mexico.
Websites that take New Mexico players are unlicensed. Offshore crypto sportsbooks are not licensed in any US state, so using one means no state regulator stands behind your balance or your payout, and nobody in New Mexico can order a refund.
What's changing
In May 2026 the Mescalero Apache Tribe and the Sandia, Isleta and Pojoaque pueblos sued Kalshi in federal court, saying its sports contracts violate the compacts and federal law. Attorney General Raul Torrez filed a separate state-court suit on June 4, 2026, alleging an unlicensed sportsbook that lets 18 to 20 year olds bet. The CFTC then sued Torrez to stop the state from regulating Kalshi. The tribes made their closing written arguments for a preliminary injunction on September 4, 2026.
On June 23, 2026, Rep. John Block urged the tribes to reopen the intertribal gaming compact, which runs to 2037, to allow statewide online betting. Reopening would need the governor, then the legislature and the Interior Secretary, and a Mescalero attorney said no talks had begun.
Tax on winnings
New Mexico taxes gambling winnings as part of income at graduated state rates, which top out at 5.9 percent, on top of federal tax. Ask a tax professional about your return.
