The crypto brokerage will offer Polymarket’s markets in-app from this week, launching in the EU as the World Cup drives record trading volumes
Blockchain.com has partnered with Polymarket to embed prediction markets directly into its app, giving eligible users the ability to trade on real-world event outcomes using crypto balances they already hold.
The function is due to go live on Tuesday as the World Cup semi-finals kick off, and will appear in the European Union but not yet in the US, according to promotional materials reviewed by Bloomberg. Blockchain.com said the integration removes the need to onboard to an external platform, connect a separate wallet or pay duplicate deposit fees before opening a position.
“We expect it to be pretty significant,” Peter Smith, Blockchain.com’s Founder and CEO, told Bloomberg.
Polymarket: From destination app to distribution layer
Polymarket has spent the past year turning itself into infrastructure other platforms plug into rather than a site users visit: it already supplies markets to X and sits inside MetaMask, where wallet holders trade its contracts without leaving the app. Rival Kalshi has pursued the same distribution model through Robinhood.
Blockchain.com brings scale for Polymarket, reporting more than 43 million verified users, 95 million wallets and over $1.1trn in transactions processed since 2011, across more than 70 jurisdictions. For a custodial brokerage, dormant balances earn little; an embedded trading product converts them into fee-generating turnover with no user acquisition cost and no build. The same calculation drove exchanges to add staking and derivatives.
Polymarket’s international exchange set a monthly record of $10.8bn in notional volume in June 2026, driven in part by World Cup trading, while its US platform recorded more than $3.5bn, up from $1.77bn in May. Blockchain.com’s announcement put football volume on Polymarket above $4.2bn across the tournament – the company’s own figure.
The concentration of activity ends will all but certainly with the final on 19 July, which explains a Tuesday launch: the value of the feature is highest in the five days it has left.
Two exchanges, one perimeter
The Blockchain.com integration connects to Polymarket’s international, on-chain exchange – the venue that remains geoblocked for US users. Polymarket’s American business runs separately as a Commodity Futures Trading Commission (CFTC)-regulated exchange, live on iOS after dropping its waitlist in May 2026, while the international platform stays closed to US IP addresses.
Growth is therefore flowing through the product outside US regulatory control while the regulated entity carries the compliance credentials.
A new CFTC probe into Polymarket began in June 2026, and state regulators have moved against prediction markets, with Minnesota banning them from August 2026 and more than 11 states issuing cease-and-desist orders – actions the CFTC is now challenging in court.
Positions are funded directly from custodied crypto and stablecoin balances and settled on-chain, with no fiat rail, external deposit or separate KYC journey in between. Prediction markets are becoming a liquidity API that any wallet can tap into.
