Native American tribes and casinos back Rhode Island fight against Kalshi and Polymarket

Published Jun 26, 2026 Updated 3h ago

Native American tribes and casinos have backed Rhode Island's legal fight against prediction market platforms Kalshi and Polymarket. The platforms maintain that their event contracts are federally regulated financial derivatives rather than illegal gambling. Rhode Island's sports betting interests are opposing the platforms' operations.

New development Jun 27, 2026

Rhode Island has sued Kalshi over its sports betting prediction markets, adding legal pressure on the platform as states move to block its sports event contracts.

Why this matters?

Kalshi and Polymarket must now fight Rhode Island gambling claims backed by casino tribes while defending federal preemption in multiple simultaneous state lawsuits. Any state-level loss risks a patchwork of geofenced markets and divergent compliance obligations.

The bigger picture

Joins a multi-state legal offensive against Kalshi and Polymarket already underway in New Mexico, Minnesota, and Illinois, with the CFTC simultaneously suing to preserve federal jurisdiction over state gambling enforcement actions.
