Kalshi, Coinbase, Robinhood, Crypto.com and Underdog form Coalition for Prediction Markets amid state lawsuits

Published May 19, 2026Updated 56d ago

Kalshi, Crypto.com, Coinbase, Robinhood, and Underdog have formed a cross-sector coalition called the Coalition for Prediction Markets to defend the prediction-market sector amid mounting state enforcement. The alliance brings together regulated exchanges, crypto platforms, and sports betting operators against claims the group attributes to gambling industry interests. The coalition launched last year but gained renewed attention as Wisconsin filed suit against Polymarket, Kalshi, Coinbase, Robinhood, and Crypto.com-linked entities, and as a US House probe into Kalshi opened. Crypto.com also partnered with Underdog to launch sports prediction markets. The grouping represents a rare collaboration across traditionally distinct sectors in the event-contract space.

Why this matters?

The Coalition for Prediction Markets gives Kalshi a shared lobbying front with four major platforms, reducing its sole exposure in court fights across Rhode Island, Wisconsin, and Minnesota. That shared war chest also pools resources against the House Oversight probe demanding surveillance records from Kalshi and Polymarket CEOs by June 5.

The bigger picture

Adds the Coalition for Prediction Markets to Kalshi's twin-track defense alongside Americans for Fair Markets, making this the second lobbying vehicle Kalshi has deployed this week as state lawsuits multiply across Rhode Island, Minnesota, and Wisconsin.
