This punk is a special case, and this sale is actually considered invalid. The owner of the punk bought the punk from themself using a loan, then repaid the loan in the same transaction ($532,414,877.01) around October 2021. On Larva Labs site, the jaw-dropping $500M transaction is crossed out in the NFT's transaction history.

The actual value of this punk is estimated to be around $276K, according to DappRadar. It has the attributes of Wild White Hair, Black Lipstick and Clown Eyes Green.

This NFT "sale" is a good reminder to check an NFT's ownership history — a spike in value may not always be legit.
