Blockchain.com taps Polymarket to bring prediction markets into its brokerage app

In focus: Polymarket prediction markets embedded inside an established crypto brokerage. Blockchain.com disclosed on July 14, 2026 that it will integrate Polymarket directly into its app, letting eligible users access event-outcome markets using assets they already hold on the platform and manage those positions all in one place. The company, which describes itself as one of the world's longest-operating crypto companies and a leading crypto brokerage, frames the move as a unified custody and prediction-market interface. The next milestone is the formal rollout notice that defines which users qualify and on what timeline.

What the integration covers

The integration brings Polymarket's prediction market infrastructure inside the Blockchain.com app, allowing eligible users to deploy existing holdings there for event-outcome positions without transferring funds to a separate platform. Everything is managed from one screen. The announcement came via a New York press release dated July 14, 2026.

The setup

Prediction markets allow participants to take positions on discrete, verifiable outcomes. For an established crypto brokerage with an existing custody base, embedding that functionality in-app extends what users can do with assets they are already holding. The "eligible users" language in the announcement indicates the rollout will not open to the full Blockchain.com account base from day one, though the specific access criteria are not disclosed in the initial release.

What to watch

No launch date appears in the July 14 announcement. The tape's next data point is the rollout notice, which should specify which user segments qualify, which asset types are accepted for prediction-market positions, and whether availability expands beyond an initial cohort.
