DEX by DEX, part 4 — Jupiter's JLP: the biggest house pool of all

If GMX and Gains are the textbook house pools, Jupiter is the cathedral. Jupiter is the largest app on Solana, its perps venue is the highest-volume non-order-book perp DEX in DeFi, and its liquidity pool — JLP — is the biggest "be the house" vault around.

What JLP is

Every Jupiter perps trader trades against a single pool: JLP, a basket of SOL, ETH, BTC and stablecoins. That pool is the counterparty to all of them, and it keeps 75% of trading fees as real yield — historically a 30–80% APY, on roughly $1.3B of assets. It is enormous, and it has worked. But make no mistake about what it is: you're the casino, plus a basket holder.

The delta-neutral wrinkle

One nuance most people miss: JLP isn't market-neutral. Because it holds SOL, BTC and ETH, you carry their price risk — if those fall, JLP falls, fee yield or not. That's why a cottage industry of third-party delta-neutral vaults has appeared: they hold JLP and short the underlying assets to hedge that exposure, isolating the pure fee yield. Clever — but it's still house yield with a hedge bolted on, not following a trader. And the hedge adds its own cost and complexity (and another layer to scrutinize).

How it compares to Hyperliquid

JLP is, again, an HLP-style product — bigger than HLP, in fact, and one of DeFi's genuine success stories for passive fee yield. But it's the same category: the house. Hyperliquid's edge isn't that it has a better house pool; it's that it pairs a house pool with the follow-a-trader vaults Jupiter doesn't offer at all.

The verdict

JLP is the most successful house pool in DeFi, and a reasonable choice if fee yield (hedged or raw) is what you're after. Just know you're underwriting traders and holding a basket — not backing a manager. For that, you're back to Hyperliquid or Drift.
