What to know:
- Third Circuit tied preemption to “trading on DCMs” after deeming Kalshi’s sports contracts swaps; Ninth Circuit requires defining the “relevant field” first.
- Third Circuit favors federal preemption for DCM-listed products; Ninth Circuit could let state gambling laws coexist with CFTC rules.
- DCM-centric field eases Kalshi’s compliance and liquidity but creates uncertainty for Web3 oracles, order books, and cross-chain clearing.

A legal split is forming as to the way courts evaluate federal preemption in respect of event contracts on designated contract markets. On the side of Kalshi, the Third Circuit ascertained that the “relevant field” for preemption was “trading on DCMs” as it considered that sports-event contracts were swaps.
Following that, the Ninth Circuit, which is the next one, wants the “relevant field” to be established first before the scope of the federal law is analyzed. This difference is critical for crypto, blockchain, and prediction market platforms that want to know whether state rules can be applied to CFTC-regulated products.
Third Circuit Links Preemption to DCM Trading
The Third Circuit’s method in the Kalshi case began with product classification. As a result of determining that Kalshi’s sports-event contracts were swaps, it decided the “relevant field” for preemption was “trading on DCMs.” This brings the displacement of state law in line with the federal regulation of designated contract markets, clearinghouses, and swap execution facilities.
For exchanges implementing smart contracts and on-chain settlement, the judgment indicates that federal law covers the field once a swap is listed on a DCM, which provides useful regulatory guidance for derivatives and event-based markets that are compliant.

Ninth Circuit Requires Defining the Field First
The Ninth Circuit’s approach actually flips the process around. They hold that the question of what the relevant field is has to be addressed first before determining the prescriptive reach of federal law. For instance, if the field is considered to be gambling or state licensing, then the authority of the state may be recognized to coexist with the regulation by the CFTC in cases involving platforms like Kalshi.
However, if the field is defined as commodities or swap trading, the federal preemption is more extensive. Since the Ninth Circuit is the one to act next, its method could be decisive in how the courts handle tokenized event contracts and Web3 platforms that have interactions with DCMs.

Opportunities and Regulatory Challenges
Locating the field in a DCM-centric world would allow companies like Kalshi to enjoy simpler compliance under the Commodity Exchange Act, which, along with other benefits, contributes to an increase in liquidity, expands the access of institutional investors, and the use of stablecoins as collateral. The approach is also detrimental to developers who are creating oracle networks, decentralized order books, and cross-chain clearing connected with prediction markets.
