Coinbase lists Kalshi tennis markets across French Open and ATP Challenger events
Coinbase Predictions has listed multiple Kalshi-sourced tennis markets across high-profile events in late May and early June 2026. Listings include French Open matches — Davidovich Fokina vs Dzumhur on May 25 and Baptiste vs Krejcikova on May 24 — and ATP Challenger events, including Andreeva vs Teichmann on May 31 and Virtanen vs Majchrzak on June 6. Each market appears under Kalshi ticker symbols, confirming Coinbase is routing contracts through Kalshi rather than issuing them directly. Coinbase's predictions vertical offers educational content, trading rules, and payout structures. The activity shows Coinbase continuing to build out its event-contract trading interface using Kalshi's regulated contracts as the underlying product layer.
Kalshi gains a second major retail distribution channel alongside Robinhood, but any dependence on Coinbase's traffic risks mirroring the Robinhood volume migration that now threatens Kalshi's World Cup flow through Rothera.
Coinbase's Kalshi integration joins recent moves by Sportradar to power Kalshi sports contracts and Robinhood to split World Cup flow, as prediction market platforms race to lock up sports data and distribution ahead of regulatory and competitive pressure.
