Second Circuit judge denies Kalshi temporary shield from New York enforcement
A Second Circuit judge on July 31, 2026 denied Kalshi's request for temporary protection against New York enforcement action. The ruling came one day after New York gaming officials urged the appeals court not to block enforcement of state gambling laws against the CFTC-registered prediction market platform. Kalshi remains exposed to state regulatory pressure while its federal preemption appeal continues in the Second Circuit.
Kalshi now faces enforcement with no federal court buffer in the state that is demanding $36 billion in damages. The denial strips away a critical procedural pause, forcing Kalshi to absorb regulatory pressure while its preemption appeal remains pending. Traders holding contracts in New York confront immediate voiding risk, with no interim federal shield comparable to what Minnesota briefly provided.
The timing compresses Kalshi's legal strategy: the Second Circuit may not rule on the core preemption question before New York acts on the damages suit or pushes for a trading halt. Polymarket holds identical CFTC registration and faces identical exposure if its own state fights reach this stage. Each procedural loss for Kalshi previews the playbook other states can replicate, turning one platform's defense into the template for nationally fragmenting CFTC-regulated markets.
