Blockchain.com Taps Polymarket as World Cup Bets Top $4.2B

Blockchain.com Plans In-App Polymarket Access

Blockchain.com said its users in eligible markets will be able to explore and trade outcomes without leaving its app, using digital assets they already hold and managing positions in one place. The release says the purpose is to avoid separate onboarding, external wallet connections and additional deposit steps.

That description leaves several practical details open. The announcement does not identify the supported assets, the networks or wallet type used, any fee schedule, the available contract categories, an initial group of countries, or whether access will arrive at once or in phases.

The timing is part of the pitch. World Cup semifinal matches are driving global attention toward sports event contracts, and Blockchain.com said it has facilitated more than $1.1 trillion in crypto transactions since its 2011 launch. The company also said it has more than 95 million wallets, a broader measure that is distinct from its 43 million verified users.

The arrangement is another example of crypto consumer apps adding adjacent financial products rather than limiting themselves to buying and selling tokens. Daily Crypto Briefs recently covered X Money’s limited beta, where the product’s availability was likewise narrower than the attention around its eventual public rollout.

For Polymarket, an embedded distribution channel could put its event markets in front of a large crypto-native audience at a moment of high sports interest. The release does not disclose a commercial agreement, a revenue split, a target for new accounts or expected trading volume, so it is not yet possible to measure the partnership’s financial effect on either company.

Blockchain.com Terms Set Limits on Prediction Markets

Blockchain.com’s user agreement, updated July 14, describes a De-Fi Wallet interface that may provide access to third-party prediction-market protocols, subject to restrictions. It says the user independently initiates and cryptographically signs transactions using that wallet.

The terms draw a clear line around Blockchain.com’s role. They say the company does not own, operate, administer, control or settle a prediction-market protocol, and does not determine prices, provide liquidity, route transactions, choose outcomes or distribute payouts. The agreement also says the availability of a protocol is not a recommendation or a representation that it is lawful or suitable for a user.

That language is consequential because it separates an app interface from the market operator. A user may see a Polymarket market inside Blockchain.com, but the parties’ legal terms assign protocol operation, market outcomes and related disputes to the third-party provider rather than to Blockchain.com.

Jurisdiction is the other unresolved boundary. The terms say prediction markets can be regulated differently by location and that Blockchain.com makes no representation that a protocol is authorized or available where a user lives. It also warns that users can lose all digital assets committed to a prediction-market protocol and lists risks including smart-contract failures, oracle errors, liquidity shortages, cyberattacks and permanent discontinuation.

That disclosure should keep the announcement from being read as a universal launch. It signals the technical route the company intends to make available, while leaving compliance screening, country access and contract eligibility to the actual rollout rules. Similar questions sit at the center of the wider U.S. crypto policy framework, where product design and regulatory treatment can change separately.

Polymarket’s U.S. Return Raises the Stakes

Prediction markets let participants take positions on whether defined real-world events occur, such as an election result, economic release or sports outcome. The price of a contract generally reflects the market’s implied probability, but it is neither a guarantee nor investment advice.

Polymarket’s international platform uses blockchain infrastructure and cryptocurrency funding, while its U.S. platform is more centralized, CFTC-regulated and funded with U.S. dollars, according to an Associated Press report. AP reported that Polymarket resumed U.S. operations at the end of 2025 after buying derivatives exchange QCEX.

The distinction matters for the Blockchain.com announcement because its terms refer to third-party prediction-market protocols and user-signed wallet transactions, but do not say which Polymarket entity or product configuration will be used in each eligible market. The companies did not immediately disclose whether the integration will include U.S. users, the international platform, or both.

AP, citing Dune data, reported that combined trading volume across Polymarket and rival Kalshi had reached $26.6 billion, up from $9.75 billion in October. That growth helps explain why wallets and brokerages are looking at event contracts as a retention product, even as regulators and sports bodies scrutinize the category’s market integrity and legal treatment.

The integration also lands as platforms experiment with ways to keep assets, tokens and market access in a single user experience. That direction is visible in the expansion of tokenized-stock products, although an event contract is a different instrument with its own settlement rules and risks.

What remains unknown is more important than the announcement’s promotional framing: when access opens, where it will be available, which assets can be used, how customers move funds into a position, and which market operator’s terms apply. The first live country rollout and the first published product rules will show whether the partnership creates a broadly usable channel or a more limited wallet feature.

The Crypto Fear and Greed Index read 25, or Extreme Fear, on July 15. The Bitcoin-focused sentiment measure does not assess prediction-market demand, but it captures the caution surrounding the broader crypto trading backdrop during the announcement.
