Kalshi and Robinhood split legal tactics to save sports event contracts
Kalshi and Robinhood are pursuing separate legal strategies to overturn court rulings that threaten their sports event contracts. The platforms are not coordinating their challenges, each mounting its own case against recent decisions that put their offerings at risk. The dual-track approach contrasts with a unified defense as both operators navigate an increasingly fragmented regulatory landscape for prediction markets.
Separate legal tracks mean two fee bills, two sets of motions, and no shared precedent win. Robinhood's deeper pockets let it absorb that cost; Kalshi's budget is already split across Nevada, Connecticut, Baltimore, and New Jersey filings. A victory for one platform does not automatically shield the other, so traders hold contracts whose validity may diverge by venue. Robinhood can weather a state-by-state geofence strategy if courts turn hostile; Kalshi cannot.
The split also prevents a single test case from reaching the Supreme Court with the industry's full weight behind it. Each platform's lawyers now argue slightly different theories, diluting the force that a united front would carry. Traders seeking clarity on which sports contracts survive must track two dockets instead of one, and the first adverse final ruling against either platform will become the benchmark regulators cite against the rest.
Kalshi now fights legal and commercial battles on three fronts simultaneously — defending its sports contracts in state and federal court while rival Novig's $125 million debut and its own product gaps erode market position.
