On July 14, the Commodity Futures Trading Commission (CFTC) took swift action to halt a Michigan state court's order that aimed to cancel trades on Kalshi, a prediction market platform. This situation arose when a Michigan judge issued a temporary restraining order at the request of the state's attorney general, intending to unwind trades that had already been executed. As a result, Michigan became the first state to challenge the integrity of completed derivative transactions in this manner.
The CFTC's emergency stay gives them up to 90 days to assess Kalshi’s proposed rule, which was initially designed to align with the court's directive. In the meantime, Kalshi is expected to continue handling open agreements through standard settlement processes, ensuring that traders involved do not face immediate losses from the halted trades.
Kalshi's proposed emergency rule would have forced liquidation of positions held by Michigan users and implemented measures to prevent further trades from residents of the state. The CFTC's chairman, Michael Selig, emphasized that a state cannot compel a designated contract market like Kalshi to violate its federal obligations. He characterized Michigan's action as unprecedented, warning that it could lead to widespread dysfunction in the trading environment. According to the CFTC, such state interference poses a major risk of undermining public confidence in the trading system, fostering fears that trades could be unwound long after execution.
This episode raises critical questions about the balance of power between state regulations and federal market oversight. The Commodity Exchange Act grants CFTC exclusive jurisdiction over swap contracts traded on approved platforms, underscoring the paramountcy of federal law in financial market operations. Michigan’s challenge is thus framed as a significant market disturbance that could alter the space of prediction markets across the country.
