Jupiter Exchange remains the highest-volume decentralized-exchange aggregator on Solana, recording $15.5 billion in 30-day volume in September 2026, according to DefiLlama data. That exceeded DFlow’s $9.2 billion and OKX’s $3.8 billion on Solana. 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. Its share of Solana aggregator volume, historically above 90%, fell to 68% by late August 2026 and reached 48% on one day, while OKX captured as much as 37% and DFlow 13%. Jupiter operates only on Solana, so claims that it leads aggregators across all blockchains require qualification against multi-chain platforms such as 1inch and Jumper. The platform is also broadening into a DeFi superapp with perpetual trading offering up to 100x leverage, lending, limit orders and dollar-cost averaging; lending deposits reached $2.41 billion on September 22, 2026. Its JUP governance token supports participation in protocol decisions.
