Blockchain.com integrates Polymarket for 43 million users ahead of World Cup semifinals
Blockchain.com has partnered with Polymarket to integrate prediction markets into its crypto app, giving 43 million verified users access to event contracts including World Cup semifinals markets starting July 14, 2026. Users can trade real-world outcomes without leaving the Blockchain.com platform or moving funds to a separate venue. The partnership positions Polymarket inside an established retail crypto brokerage as competition intensifies with Coinbase, Robinhood, and DraftKings in the event-trading space.
For Polymarket, the Blockchain.com deal solves distribution at the exact moment the sector's battlefield has shifted to user acquisition. Kalshi just landed in ChatGPT search results. DraftKings built DKeX to own its 50-million-user funnel. Polymarket needed a mainstream surface or risked being squeezed between them.
The 43 million verified users give Polymarket a brokerage-native audience that already trusts on-chain products, which matters because trust is the conversion barrier for first-time prediction-market traders. The World Cup timing is not accidental. Polymarket can prove that crypto brokerages convert sports-event flow as cleanly as dedicated prediction-market apps, Coinbase and Robinhood become logical next integration targets. If conversion lags, the deal becomes a branding footnote rather than a template.
Polymarket joins Kalshi in landing a mainstream distribution integration during the World Cup window, after Kalshi secured OpenAI puts Kalshi World Cup odds in ChatGPT search results just days earlier.
