What happened

Prediction-market platforms Kalshi and Polymarket are facing pressure on several fronts. Baltimore sued both companies, with Coinbase, Robinhood and Webull also included in the action. Separately, a Washington court halted most Kalshi markets in that state.

The record also says JPMorgan reportedly cut Polymarket’s banking relationship. Meanwhile, Kalshi is reported to be in talks for a $750 million raise at a $40 billion valuation.

Why it matters

The developments point to a more difficult operating environment for prediction markets despite reported investor interest in Kalshi. Legal action in Baltimore, a Washington-specific court halt and a reported banking disruption could make expansion more dependent on state-by-state outcomes.

For readers tracking the sector, the immediate question is whether these pressures remain isolated or develop into a broader patchwork of restrictions and service-provider limits.

What to watch

Watch for the next court filings and decisions tied to Baltimore’s lawsuit and the Washington order, as well as any confirmation or further detail on Polymarket’s reported banking situation. Any public update on Kalshi’s reported financing talks would also clarify how investors are weighing the sector’s legal and banking risks.

What to watch

Watch for court updates in Baltimore and Washington, confirmation of the reported JPMorgan action, and any public financing update from Kalshi.
