Former Solicitor General Elizabeth Prelogar has submitted a significant amicus brief in the Sixth Circuit appeal involving Kalshi, a prediction market platform. The brief, filed on behalf of PredictAction, emphasizes the Commodity Futures Trading Commission's (CFTC) exclusive jurisdiction over prediction markets. Prelogar outlines the historical context of this jurisdiction and presents three critical arguments that challenge the states' positions, for which they have yet to provide substantial counterarguments.
