Robinhood owns the rails in prediction markets, a fast-growing business about to out-earn its crypto trading. Event-contract revenue went from $3M in Q1 2025 to $104M a year later, and Bernstein expects it to pass crypto revenue this quarter, reaching $586M in 2026 and $1.7B by 2028. Owning 90% of MIAXdx and launching the CFTC-licensed Rothera with Susquehanna lets it charge 0.6 cents per contract versus two cents elsewhere while keeping all the economics across 27 million funded customers. x.comÂ
