SolFi has consistently maintained the largest market share on Jupiter for several weeks, staying above 25% throughout. Lately, OpenBook’s share has been growing and now stays around 17–20%. This increase matches the growing interest in central limit order books (CLOBs). Overall trend highlights a major shift: private DEXs like SolFiAMM , ZeroFi, and Obric now collectively account for 35–45% of Jupiter's total trading volume. A crucial insight is that to win market share on Jupiter, you must dominate the SOL-USDC pair, which is by far the most actively traded pair on the platform. SolFi’s ability to offer better prices than other venues has been a major reason behind its rapid growth. SolFi employs a vault-based private execution model. Interestingly, SolFiAMM doesn’t try to cover every trading pair, instead, it focuses on the main ones . In the last 7 days alone, ~ 80% of SolFi’s volume came just from SOL-USDC trades — a pattern similar to openbookdex , which also relied heavily on this pair.
