Every coin on pump.fun starts its life inside a bonding curve — an automated market-maker contract that prices the token based purely on how much SOL has been deposited into it. No order book, no market makers, no team setting the price. The curve is the price. Understanding how it works is the single most useful thing a pump.fun trader can know, because every strategy on the platform is really a strategy about position on the curve.
How the curve prices a coin
When a token launches, its bonding curve starts nearly empty and the token is essentially free. Buyers deposit SOL into the curve contract and receive tokens; the smart contract continuously recalculates the price so that each subsequent buy costs slightly more than the last. More SOL in the pool = higher price. Selling works in reverse: tokens returned to the curve release SOL back, and the price eases down. The whole thing runs on-chain and automatically — nobody can pause it, change the formula, or manually reprice the coin.
What “graduating” actually means
When roughly 85 SOL accumulates in the curve, the contract has pooled enough liquidity to fund a real market. At that point the token graduates: the pooled SOL and the remaining token supply migrate automatically into a PumpSwap pool (a Solana DEX), and the liquidity is locked. From that moment the token trades like any other Solana token — visible on DEX screeners, buyable by anyone with a wallet, and no longer tied to the curve.
Graduation is the finish line every launch is racing toward. The “curve percentage” you see on trackers and cards is simply how full the bonding curve is: 0% means the coin just launched, 70% means it has raised most of its SOL, and 100% means it just graduated.
Why curve position matters to traders
Buying early on the curve means a cheaper entry — but also the highest risk, because most coins never get past the first few buyers. Buying late (80–99%) means the coin has proven real demand and is close to graduating, but the remaining upside from the curve itself is smaller, and post-graduation the price is set by the open market, which can dump hard. This is why trackers sort coins by curve progress: a coin climbing quickly through 40%, 60%, 80% is the platform’s clearest momentum signal.
The honest math
Thousands of coins launch on pump.fun every day and only a fraction ever graduate — and of those that do, most still lose value afterward. The curve’s transparency cuts both ways: everyone can see the momentum, which is exactly why coins that fill their curves attract a rush of exit liquidity right at graduation. Size your positions like the lottery tickets they are.
