Robinhood has announced that the company has crossed 4 billion contracts that have been traded all-time. According to a comment by the CEO, Vlad Tenev, on X, the company registered more than $2 billion in the third quarter alone. “Robinhood Prediction Markets just crossed 4 billion event contracts traded all-time, with over 2 billion in Q3 alone. And we’re just getting started,” Tenev announced on X. Elsewhere, recent reports showed that Kalshi has overtaken Polymarket to become the leading platform in prediction market and event-based contract trading, capturing nearly two-thirds of the sector’s volume as regulated platforms gain ground over offshore competitors. The surge reflects growing adoption of U.S.-regulated platforms and changing trading behaviors in the market. According to Dune Analytics data, Kalshi accounted for 62% of total prediction market volume from September 11–17, processing over $500 million in weekly trading while maintaining an average open interest of $189 million. Polymarket, by comparison, generated $430 million in volume with average open interest of $164 million, suggesting slower turnover and “sticker positions” among its traders. “Event contracts have generated high demand because they provide a maximally direct way to get exposure to events that affect businesses, people, and the economy, and they provide the most accurate signal on what the likelihood of future events is,” said Jack Such from Kalshi, responsible for Business & Media Development.
