Solana-based exchange Jupiter said it will bring prediction platform Polymarket onto Solana for the first time through its own trading interface.
In a post on X, Jupiter said it will integrate prediction platform Polymarket into its Solana-based exchange, bringing Polymarket markets to Solana through Jupiter’s interface. The team presented the move as an expansion of on-chain prediction trading for its users.
The exchange also disclosed a $35 million strategic investment in its JUP token from crypto investment firm ParaFi Capital. The deal was funded entirely with Jupiter’s dollar-pegged JupUSD and includes a longer lock-up, which Jupiter said ties ParaFi more closely to the project’s future growth.
Polymarket Volumes and Transactions Hit Record Levels
Data from Dune Analytics show Polymarket’s weekly notional volume climbing from well under $100 million in April 2024 to peaks of around $1 billion by late 2025 and early 2026. Through much of late 2025, weekly volume often stayed above $500 million, with politics, world events, and crypto markets accounting for the bulk of trading and categories like weather, tech, and culture adding smaller but growing slices.
Polymarket’s market share reached 26.49% over seven days, 27.45% over 30 days, and 26.44% over 90 days, while Open interest totaled $405.85 million, implying a volume-to-open-interest ratio of 31.83%.
Jupiter–Polymarket Integration: What It Means for Traders
The integration is expected to give Solana users a single venue for prediction markets and token swaps, letting them reach Polymarket’s catalogue of event markets directly through Jupiter while leveraging Solana’s low fees. Hosting predictions alongside swaps turns Jupiter into more of an all-purpose trading hub, where users can move between spot tokens and event contracts in one place.
Additionally, planned discovery tools and trading features should make it easier for developers and market makers to list new markets, route orders, and deepen liquidity across Polymarket’s growing set of prediction markets.
