PANews reported on March 2nd that, according to Arkham's report on Arthur Hayes' net worth and on-chain holdings, BitMEX co-founder Arthur Hayes' net worth is estimated to be between $200 million and $350 million. Hayes' wealth exceeded $1 billion during the 2021 bull market, making him widely reported as one of the youngest billionaires in the crypto industry, but it has since shrunk significantly with the market correction.

Hayes' on-chain holdings currently stand at $42 million, with the largest holding being the USDC stablecoin, worth nearly $27 million. He also holds $8.6 million worth of Ether.Fi's EETH and WEETH products, and $8.5 million worth of investments in Ethena (ENA), Lido (LDO), and Pendle (PENDLE). A major component of his wealth is his stake in BitMEX. Although BitMEX reached a valuation of $3.6 billion in 2019 with an annual trading volume exceeding $1 trillion, its current trading volume is approximately $385 million. Arkham conservatively estimates its 2026 valuation at $500 million. As a co-founder, Hayes could potentially hold up to 33% of the shares, but this has likely been diluted after years of turmoil.
