  Non-Fungible Tokens (NFTs) are non-interchangeable assets, usually digital
art, which are stored on the blockchain. Preliminary studies find that female
and darker-skinned NFTs are valued less than their male and lighter-skinned
counterparts. However, these studies analyze only the CryptoPunks collection.
We test the statistical significance of race and gender biases in the prices of
CryptoPunks and present the first study of gender bias in the broader NFT
market. We find evidence of racial bias but not gender bias. Our work also
introduces a dataset of gender-labeled NFT collections to advance the broader
study of social equity in this emerging market.
