Bonding Curve

An automated market maker mechanism that determines token price based on supply and demand, used by pump.fun to manage token launches.

A Bonding Curve is a mathematical formula that automatically determines the price of a token based on its circulating supplyยน. On pump.fun, this mechanism ensures fair and transparent token launches.

As of October 2025, bonding curve parameters and graduation thresholds are subject to platform updates.

How Bonding Curves Work

The bonding curve creates a direct relationship between:

  • Token Supply: Number of tokens in circulation
  • Token Price: Cost to buy the next token
  • Market Cap: Total value of all tokens

pump.fun Implementation

On pump.fun, the bonding curve:

  • Starts at a low price when few tokens are minted
  • Increases price as more tokens are purchased
  • Reaches graduation at ~$69,000 market capยฒ
  • Migrates to Raydium for open market trading

Key Benefits

  • No rug pulls: Liquidity is locked in the curve
  • Fair launch: Everyone pays market price
  • Predictable pricing: Mathematical formula determines cost
  • Instant liquidity: No need to wait for market makers

Trading Implications

  • Early buyers get lower prices
  • Price increases with each purchase
  • Selling pressure can push prices down the curve
  • Large buys can significantly move price up

Understanding bonding curves is essential for successful pump.fun trading.
