Arithmetic on today's supply, not a forecast. It assumes nothing about whether Ethereum could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Ethereum has 121,931,994 ETH in circulation at $2,514.73 each, which is $306.63B. Holding that supply still and putting Pump.fun's $1.55B in its place gives $12.7395 per ETH.
Ethereum is already worth more than Pump.fun. Moving to the smaller cap would take ETH down to $12.7395, which is 0.005x of what it trades at now.
Supply is held still, and in practice it moves: coins are minted, burned and unlocked, and every one of those changes the price a given market capitalisation implies. The figure also says nothing about whether the money exists to buy ETH at that level, which is the part that actually decides a price.
$12.7395 per ETH. That is Pump.fun's current market capitalisation of $1.55B divided across the 121,931,994 ETH in circulation.
0.005x. Ethereum trades at $2,514.73 today and Pump.fun's market cap is $1.55B against Ethereum's $306.63B.
No. It is one division: Pump.fun's market capitalisation spread over the supply of ETH that exists today. It assumes nothing about whether Ethereum could attract that much money, and it holds the supply still when in practice supply changes.
It sets it. Market cap is price times circulating supply, so the same $1.55B of market cap spread over more coins gives a lower price per coin. This uses the 121,931,994 ETH in circulation now.
