Robinhood Derivatives lists US Open tennis event contracts after Kalshi deal
Robinhood Derivatives listed event contracts for a 2026 US Open Women's Singles match between Qinwen Zheng and Yulia, according to a September 2 report. The offering marks an expansion of sports event contracts under Robinhood's derivatives unit. The platform previously introduced a US Open tennis market on August 31. Both listings add tennis to Robinhood's event contract portfolio alongside existing offerings in other sports.
Robinhood's tennis launch tests whether a non-exclusive platform can capture meaningful volume on a tournament locked down by a rival. Kalshi's official US Open partnership gives it court-side marketing and ESPN broadcast presence that Robinhood cannot match. Derivatives desks at competing platforms must now price sports contracts knowing that exclusive deals may choke off their event inventory.
The split between official partner status and functional market access forces traders to chase liquidity across multiple venues for the same match outcomes. For Robinhood, the bet is that its broader brokerage user base converts faster than Kalshi's standalone app can scale. If tournament-level exclusives become the norm, non-partner platforms face a future of second-tier sports inventory or expensive partnership bidding wars.
Robinhood Derivatives joins Kalshi and Novig in launching US Open tennis event contracts this month, deepening the competition among regulated prediction-market platforms for Grand Slam audience share despite Kalshi's exclusive multi-year partnership with the tournament itself.
