Robinhood stock rally spotlights event-contract and Bitstamp volume acceleration
Robinhood (HOOD) shares climbed more than 4% after preliminary June data showed event-contract volumes accelerating sharply ahead of July. Contracts traded on the platform jumped from about 3.1 billion in the first 18 days of June to roughly 5.2 billion by June 25, a surge of about 68%, or 2.1 billion contracts. The rally also drew attention to Bitstamp crypto volumes, which ran ahead of May's full-month total by early June. Event-contract revenue at Robinhood is projected to surpass cryptocurrency revenue at a roughly $200 million annualized pace.
Robinhood's event-contract surge cements its role as Kalshi's largest CFTC-registered competitor rather than a retail partner. The June spike arrives as Robinhood's Rothera infrastructure has already displaced a revenue-sharing pipeline where each platform earned 1 cent per contract. Kalshi now must replace that lost retail flow with institutional volume or new partnerships while defending market-maker relationships against Robinhood's built-in user base.
The $200 million annualized pace gives Robinhood capital to outspend rivals on marketing and product expansion just as DRW, Wintermute, and IMC are building liquidity desks for the sector. Kalshi's push toward a $40 billion valuation depends on proving it can attract institutional flow fast enough to offset the departure of its biggest retail channel. The first platform to lose dedicated market-maker support to Robinhood's larger order book will face widening spreads at the worst moment.
