Underdog Sues Five States in Prediction Markets Push

Underdog filed federal lawsuits against five states this week and surrendered its daily fantasy sports licenses in seven additional states, making a decisive push into sports prediction markets.

Why It Matters

Prediction markets occupy a legal grey zone that Underdog is now forcing courts to define. By seeking preemptive injunctions — rather than waiting for regulators to act — the company is trying to set federal precedent before individual states can shut it down. If any injunction holds, it creates a legal template competitors can copy. If courts side with the states, Underdog faces an accelerated shutdown in those jurisdictions with no DFS fallback, having already abandoned those licenses (per SBC Americas). Players in affected states should monitor their account access closely.

Context

Prediction markets — where users buy contracts on sports outcomes priced like financial instruments — have grown rapidly as operators seek to escape the patchwork of state sports-betting licensing. On Tuesday, September 9, 2026, Underdog formalized its pivot by filing the five lawsuits simultaneously (SBC Americas). The voluntary surrender of DFS licenses in seven states signals the company views the two business models as legally incompatible and has committed fully to the new structure.

What's Next

The federal courts must now rule on whether to grant the preliminary injunctions; any early rulings will signal how hospitable the federal judiciary is to the prediction-markets model. Rivals and regulators across all 50 states will be watching closely before deciding their own moves.

Gambling involves risk. Prediction markets are subject to evolving and uncertain regulation; check your jurisdiction before participating.
