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, widely reported as one of the youngest billionaires in the crypto industry, but subsequently shrank significantly with the market correction. Hayes' validator on-chain holdings are currently $42 million, with his 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 investments in Ethena (ENA), Lido (LDO), and Pendle (PENDLE) worth $8.5 million. The main component of his wealth is his BitMEX equity holdings. Despite BitMEX reaching a valuation of $3.6 billion in 2019 and boasting an annual trading volume exceeding $1 trillion, its current daily 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.
