Kalshi Faces Federal Injunction Over Unlicensed Derivatives Trading Platform

Kalshi’s legal battle now hinges on how the Sixth Circuit interprets the Commodity Exchange Act’s definition of a “swap.” In Ohio, Chief Judge Sarah D. Morrison rejected Kalshi’s claim that sports‑event contracts fall under that definition, emphasizing that swaps traditionally affect commodity prices such as energy, weather or foreign‑exchange rates. She invoked the “Absurdity Doctrine”—a principle articulated by Justice Scalia—to argue that extending the swap label to a college basketball score would produce a result Congress never intended (The Synthesis, March 21). Morrison’s ruling therefore holds that the Commodity Exchange Act does not pre‑empt Ohio’s gambling statutes, forcing Kalshi to comply with state law while it prepares an appeal to the Sixth Circuit.

By contrast, Judge Aleta Trauger in the Middle District of Tennessee reached the opposite conclusion three weeks earlier. Trauger found that the economic fallout from sporting events—merchandise sales, advertising revenue and even employment patterns—constitutes the “downstream economic consequences” the Act cites when defining swaps. According to her analysis, those consequences satisfy the statutory language, meaning the federal framework pre‑empts Tennessee’s sports‑wagering regulations (The Synthesis, March 21). Trauger’s decision therefore granted Kalshi a preliminary injunction, effectively barring the state from enforcing its gambling law against the platform.

The split between the two district courts creates a rare intra‑circuit conflict that the appellate court must resolve. Both judges examined the same statutory text, the same product (Kalshi’s prediction‑market contracts), and the same underlying legal question, yet arrived at diametrically opposed outcomes. If the Sixth Circuit sides with Ohio, it will cement a narrow reading of the swap definition that preserves state gambling authority and forces prediction‑market operators to seek separate CFTC licensure or restructure their offerings. If it adopts Tennessee’s broader interpretation, it could establish a de facto federal pre‑emption regime for a wide swath of event‑based contracts, potentially reshaping the regulatory landscape for emerging “prediction market” platforms nationwide.

Kalshi’s broader litigation strategy reflects a patchwork of victories and setbacks across the United States. The company secured preliminary injunctions in Tennessee (February 2026) and New Jersey, where courts found the Commodity Exchange Act likely pre‑empted state gambling rules (The Synthesis, March 21). Conversely, it lost in Ohio and Maryland, where judges denied similar relief (The Synthesis, March 21). California’s Northern District also rejected a tribal challenge, holding that the Indian Gaming Regulatory Act does not apply to third‑party platforms and that CFTC‑regulated transactions are exempt from illegal internet gambling statutes. These divergent rulings underscore the absence of a unified federal precedent and highlight the stakes of the pending Sixth Circuit decision.

Beyond the legal technicalities, the outcome will have material implications for Kalshi’s business model. The platform reported that Super Bowl trading volume surpassed $1 billion, a figure cited by CNBC as evidence of robust user demand for event‑based contracts (CNBC). If the appellate court validates the Tennessee approach, Kalshi could continue expanding its market without seeking separate state licenses, leveraging its CFTC registration to operate nationwide. If the Ohio view prevails, the company may need to restructure its contracts to avoid swap classification or negotiate licensing agreements with each state’s gambling regulator, potentially curbing growth and increasing compliance costs. The Sixth Circuit’s ruling, expected later this year, will therefore set the first appellate‑level precedent on prediction‑market pre‑emption and determine whether Kalshi can scale its platform under a unified federal framework or must navigate a fragmented state‑by‑state regime.
