DraftKings Is Running Prediction-Market Ads in California — Where Sports Betting Is Illegal

By classifying its markets as federal event contracts, DraftKings launched Predictions in California and three other non-sportsbook states. A class-action suit and the tribes are already pushing back.

DraftKings is advertising a sports-adjacent betting product in California — a state where sports betting is flatly illegal. It can do this because it isn't calling it sports betting.

The loophole, stated plainly

DraftKings launched its Predictions platform in California and began running state-specific ad campaigns this week in California, Georgia, Texas and Florida — four of the biggest markets with no legal sportsbook. The mechanism is the same one Kalshi and Polymarket use: classify the markets as event contracts regulated by the federal Commodity Futures Trading Commission, not as sports wagers governed by state law. If they're federal derivatives, the argument goes, California's ban doesn't reach them.

California voters rejected two sports-betting initiatives in 2022. DraftKings is now offering a product that looks a lot like the thing voters said no to — through a federal side door.

The pushback is already here

This is not going unchallenged. A class-action lawsuit was filed in federal court in California on Aug. 13, alleging illegal sports betting via prediction markets and seeking damages and an injunction. Tribal gaming leaders — who hold California's gaming compacts and have the most to lose — are objecting loudly. The state is shaping up as the biggest single battleground in the prediction-market fight.

Why it matters

California is the industry's holy grail: the largest U.S. market, permanently locked to sportsbooks. If the event-contract theory survives the courts there, prediction markets don't just compete with sportsbooks — they route around the entire state-licensing system in the one place operators most want in. If it fails, the CFTC shield cracks in the market that matters most. Either way, what happens in California won't stay in California.
