Jupiter (JUP) is the dominant trading hub on the Solana blockchain — it started as a 'DEX aggregator' (finding you the best price for a token swap by routing across all of Solana's exchanges) and grew into a full 'DeFi superapp'. Today it offers swaps, limit orders, perpetual futures (leveraged trading), lending, liquid staking, its own stablecoin (JupUSD) and even integrated prediction markets. If you trade on Solana, you're very likely using Jupiter under the hood. JUP is its token, used for governance and increasingly tied to the platform's economics via buybacks and burns. Its bet is to be the single front door for all on-chain finance on Solana.
Where it stands today: Jupiter is deeply entrenched — it controls the vast majority (around 95%) of Solana's DEX-aggregation and consistently ranks among the top Solana protocols by both value locked and revenue. It's expanded aggressively (perps, lending, a stablecoin, a Polymarket prediction-market partnership) and even became a major Solana validator via its liquid-staking token. On the token side, it burned billions of JUP from supply and has run tens of millions in buybacks to offset unlock pressure, though JUP has still traded weakly. So today it's the powerful, revenue-generating gateway to Solana DeFi, actively working to make its token capture more of that success while fighting unlock-driven supply.
