New Mexico tribes wrap up closing arguments against Kalshi sports betting
Three New Mexico pueblos and one tribe wrapped up closing arguments urging a federal judge to prohibit Kalshi's online sports betting. The tribal nations argue that Kalshi's sports event contracts infringe on their gaming sovereignty. One plaintiff filing cites a new appeals court ruling that restores state regulators' oversight of prediction markets. The case follows Kalshi's earlier federal court victory against the CFTC.
A ruling against Kalshi in New Mexico would add another state to the list where CFTC registration no longer blocks local gambling enforcement. The tribal sovereignty angle offers courts a distinct legal path beyond the preemption fights already unfolding in Nevada, Arizona, and Connecticut. Each new venue that rejects Kalshi's federal shield emboldens the next set of plaintiffs.
Kalshi's legal spend compounds across parallel cases while its national sports market fragments. The pueblos' gaming compact rights give them standing that generic state regulators lack, potentially producing a separate precedent that reaches Polymarket and other CFTC-registered platforms offering sports-linked contracts. Traders hold positions whose legality shifts with geography, not regulation.
