Polymarket is now using Chainlink’s oracle technology to automate and strengthen the accuracy of crypto price prediction markets on the Polygon blockchain.
Key Takeaways
- Polymarket and Chainlink have partnered to bring real-time asset pricing data to prediction markets.
- The integration is live on Polygon and will initially support crypto market predictions.
- Chainlink’s oracle system automates market resolution using tamper-proof, timestamped data.
- The move follows CFTC’s regulatory approval allowing Polymarket to reenter the U.S. market.
What Happened?
Polymarket, a leading crypto-based prediction platform, has integrated Chainlink’s decentralized oracle network to improve the speed and reliability of its market resolution system. The new collaboration went live on the Polygon blockchain and marks a major milestone in bringing transparent, automated outcomes to crypto prediction markets.

Chainlink Powers Objective Market Resolutions
The primary benefit of the integration is to eliminate delays and manipulation risks associated with manually resolved markets. Chainlink will feed Polymarket with real-time, deterministic data to automatically resolve asset pricing predictions, including popular crypto pairs like Bitcoin.
This is achieved using Chainlink’s Data Streams and Automation tools, which deliver timestamped pricing data directly on-chain. Once a market’s time limit expires, the system can instantly and automatically resolve the outcome based on objective data, removing the need for third-party intervention or social voting.
According to Chainlink co-founder Sergey Nazarov, this partnership is a “pivotal milestone” for the prediction market space. He noted that by using tamper-proof oracles, prediction markets can evolve into “reliable, real-time signals the world can trust.”
Focused Rollout on Polygon
The integration is currently live on Polygon, the Ethereum Layer 2 scaling solution that Polymarket uses by default. Polygon helps ensure fast and low-cost transactions, while Chainlink brings external data into the chain.
This allows Polymarket users to participate in “15-minute crypto up/down polymarkets,” which offer rapid settlement based on Chainlink’s data feeds. These short-term markets are expected to be just the beginning, with both companies planning to expand beyond crypto pricing into broader prediction categories.
Subjective Markets Still a Challenge
While this integration greatly improves the resolution of objective, fact-based markets like asset prices, both firms acknowledge that subjective markets remain unresolved. These markets, which depend on interpretations or opinions (such as political outcomes), have typically relied on social voting or governance mechanisms.
Chainlink and Polymarket are exploring ways to bring more integrity to subjective predictions using oracles, though no timeline or solution has been announced yet. The companies believe minimizing reliance on social voting could reduce bias and improve the legitimacy of prediction market outcomes.
Regulatory Green Light and Political Moves
This integration comes at a time when Polymarket is reestablishing its presence in the U.S. following a no-action letter from the Commodity Futures Trading Commission (CFTC) earlier this month. The approval gives Polymarket more room to operate legally within U.S. jurisdictions, an important step for growth.
In another move that deepens its U.S. ties, Polymarket recently added Donald Trump Jr. to its advisory board and secured funding from 1789 Capital, a venture fund closely linked to U.S. politics.
CoinLaw’s Takeaway
In my experience watching the evolution of prediction markets, speed and credibility are everything. Polymarket integrating Chainlink is a game-changer. It brings real-world accountability to what was once an experimental crypto niche. If you’ve ever watched a market close and waited hours or even days for a resolution, you’ll understand how valuable this is. I found it especially promising that they’re tackling subjective markets next. That’s the real frontier. Trust in oracles could redefine how we bet on elections, court rulings, or even entertainment outcomes. It’s a step closer to making crypto prediction markets truly mainstream.
