The Underdog Tennessee Lawsuit 2026 adds another state to a growing legal map. Underdog has sued Tennessee Attorney General Jonathan Skrmetti and the Tennessee Sports Wagering Council. The suit follows a state cease-and-desist order against Underdog’s sports event contract platform. As a result, Tennessee becomes the seventh state Underdog has taken to court.
Underdog Tennessee Lawsuit 2026: The Core Claims
Underdog filed in federal court in Nashville. The company operates as a Designated Contract Market under the CFTC. It argues that this status lets it offer event contracts nationwide. Therefore, it says Tennessee gaming rules do not apply.
The complaint leans on federal preemption. Underdog says the Commodity Exchange Act gives the CFTC exclusive power over swap exchanges. Additionally, it argues that its pick’em contests count as fantasy sports under existing Tennessee law. The company wants a declaratory judgment and a permanent injunction.
Meanwhile, Tennessee wants to fine and penalize Underdog. State regulators say the company offers sports-adjacent products without a sports betting license.
Why It Matters For Players
Underdog faces a tough legal road. Earlier this year, a federal judge in Tennessee ruled in a Kalshi case that sports contracts are swaps. However, the Sixth Circuit reversed that ruling in September. The appeals court said these contracts are unlikely to count as swaps. It also said states keep power to enforce local betting rules. That decision binds federal judges in Tennessee.
For players, the risk is practical. If Tennessee wins, Underdog may have to pull its contracts from the state. Open entries could face early settlement or refunds. Furthermore, other prediction platforms could face the same pressure.
Underdog has filed similar suits elsewhere. Last month, it sued Massachusetts, New Mexico, Ohio, Washington, Wisconsin and Connecticut within a single week. In addition, IG Group is in the process of buying the company.
Casino Bonus Streak Perspective
We think Tennessee players should stick with licensed sportsbooks for now. Licensed books answer to the state and follow clear complaint rules. In contrast, event contract platforms sit in a legal gray zone. If you want value while the courts decide, start with our best casino bonuses page.
