Polymarket Expands to Solana Through Jupiter Integration in $35M JUP Deal

• Polymarket will launch on Solana via Jupiter, bringing prediction markets directly into the exchange’s on-chain trading platform.
• ParaFi invests $35 million in JUP via JupUSD at spot price, with an extended lockup to support Jupiter’s buildout.

Jupiter, a Solana-based decentralized exchange, said it will integrate Polymarket on its platform, marking Polymarket’s first planned expansion to Solana. Jupiter stated on X that users will be able to access prediction markets “on one onchain platform.” This integration is part of a broader effort to build a dedicated prediction-market section within Jupiter’s product suite.

Polymarket operates event-based markets where traders take positions on outcomes tied to topics such as elections, economic data releases, and major news events. The exchange described Polymarket as a leading prediction market in crypto and framed the integration as a way to expand market access for Solana users through Jupiter’s existing interface. 

The companies did not share details on custody arrangements, market structure, or how users will route orders through the integration.

Last December, MetaMask added native Polymarket access in MetaMask Mobile, allowing users to join prediction markets and place on-chain positions without leaving the wallet. CNF reported that MetaMask also enabled MetaMask Rewards points for eligible Polymarket interactions while keeping transactions self-custodied within the app.

ParaFi Capital Backs Jupiter with $35 million JUP Purchase

Alongside the Polymarket announcement, Jupiter disclosed a $35 million strategic investment from ParaFi Capital in the JUP token. The exchange said the transaction was completed at spot price and settled entirely in JupUSD, the project’s dollar-pegged token. The exchange added that ParaFi agreed to an extended lockup for the purchased JUP, but did not specify the lockup duration or any additional terms.

Jupiter’s co-founder, meow, said “Jupiter predict” will be a core focus over the next year. Planned work includes prediction-market APIs, improved market-discovery features, and new trading mechanisms for prediction products. Jupiter did not provide a rollout date for Polymarket on Solana or a development timeline for the related tooling.

Prediction markets have gained wider usage over the past year as traders use them to express views on event outcomes. At the same time, parts of the sector have faced regulatory attention in some jurisdictions, creating varying operating conditions for platforms depending on where users are based. 

Jupiter’s existing on-chain activity remains concentrated in swaps and related DeFi services on Solana. Data from DefiLlama put total value locked on the platform at about $2.35 billion as of Monday, with annualized fees near $650 million and annualized protocol revenue around $150 million. 

The DEX said the ParaFi-backed funding will support work on on-chain financial infrastructure, while the Polymarket integration expands its prediction-market offering on Solana.

Additionally, the exchange recently launched JupUSD, a U.S. dollar-pegged stablecoin for Solana, stating that about 90% of reserves are in USDtb backed by BlackRock’s BUIDL fund, and the rest in a USDC liquidity buffer. As we covered, JupUSD is integrated across the exchange’s products, with audited, open-sourced contracts and institutional self-custody via Anchorage Digital.
