Jupiter Exchange remained Solana’s highest-volume decentralized-exchange aggregator, recording $15.5 billion in 30-day volume in September 2026, ahead of DFlow at $9.2 billion and OKX at $3.8 billion, according to DefiLlama data. Separately, Jupiter Lend reached a record $2.41 billion in deposits on September 22, 2026, about 27% above approximately $1.9 billion in August. Since launching in October 2021, Jupiter has routed more than $1.28 trillion across over 20 Solana decentralized exchanges and automated market makers, including Raydium, Orca and Meteora, although its aggregator share fell from historically above 90% to 68% by late August and as low as 48% on one day. Jupiter is broadening into a DeFi superapp with lending, perpetual trading offering up to 100x leverage, limit orders and dollar-cost averaging. Its Jupiter Lend v2 upgrade introduced Smart Collateral and Smart Debt, allowing eligible assets to earn lending interest and automated market maker fees simultaneously through Fluid’s infrastructure.
