Odaily Planet Daily reports that, according to Arkham’s net worth and on-chain holdings report on Arthur Hayes, the co-founder of BitMEX has an estimated net worth between $200 million and $350 million. Hayes’s wealth once exceeded $1 billion during the 2021 bull market and was widely reported as one of the youngest billionaires in the crypto industry, but has since declined significantly due to market corrections.
Hayes's on-chain holdings currently amount to $42 million, with the largest position being the USDC stablecoin, valued at nearly $27 million. He also holds $8.6 million in Ether.Fi’s EETH and WEETH products, and $8.5 million in investments including Ethena (ENA), Lido (LDO), and Pendle (PENDLE). The primary component of his wealth is his stake in BitMEX. Although BitMEX reached a $3.6 billion valuation in 2019 with annual trading volume exceeding $1 trillion, its daily trading volume is now approximately $385 million; Arkham conservatively estimates its 2026 valuation at $500 million. As a co-founder, Hayes may have held up to 33% of the company, but this stake may have been diluted over the years due to various developments.
