Arthur Hayes went from trading derivatives at Deutsche Bank and Citibank to inventing the tool that reshaped crypto trading: the perpetual swap. That invention turned BitMEX, the exchange he co-founded, into a derivatives powerhouse, until a Bank Secrecy Act case forced him out as CEO in 2020. Pardoned by Donald Trump in 2025, Hayes now leads Maelstrom, his family office, and remains one of crypto’s most closely watched voices on markets.
Who Is Arthur Hayes?
Arthur Hayes was born in 1985 in Detroit, Michigan, and grew up in Buffalo, New York, where he attended the Nichols School and competed on the tennis and cross-country teams. He graduated from the Wharton School at the University of Pennsylvania in 2008 with a degree in economics, then moved to Hong Kong to start his career in banking rather than take the more conventional route through New York or London.
That move shaped everything that followed. Hayes spent three years at Deutsche Bank as an equity derivatives trader before joining Citibank in 2011 as a Delta One trader, market-making exchange-traded funds across Asia. He was laid off from Citibank in 2013, a turning point he has described in interviews as the push that sent him looking at Bitcoin seriously for the first time.
In 2014, Hayes teamed up with Ben Delo and Samuel Reed to launch BitMEX, a crypto exchange built for experienced traders who wanted higher leverage and more complex products than spot exchanges offered at the time. The three founders came from different backgrounds: banking, mathematics, and software engineering, and that mix showed up in the product they built.
Within its first year, BitMEX was processing over a billion dollars in trading volume and had become one of the most talked-about platforms in crypto. Hayes has remained one of the industry’s most recognizable figures ever since, alongside the founders and executives profiled in our crypto personalities hub.
Arthur Hayes’ Career and Contributions
Hayes’ career splits into three distinct chapters: the product he invented, the legal fallout that ended his time as CEO, and the family office he leads today.
The Perpetual Swap
Hayes’ most lasting contribution to crypto markets is the perpetual swap, a derivatives contract with no expiration date that tracks an underlying asset’s price through a funding-rate mechanism. Before BitMEX, futures contracts on Bitcoin were clunky and thin. The perpetual swap solved that, and it has since been copied by nearly every major exchange in the industry, from Binance to OKX to Bybit.
The BitMEX Bank Secrecy Act Case and Trump’s 2025 Pardon
Hayes ran BitMEX as CEO from its 2014 launch until October 2020, when U.S. regulators charged him and his co-founders with operating an unregistered trading platform and violating the Bank Secrecy Act. He stepped back from his executive role immediately and later pleaded guilty, receiving six months of home confinement, two years of probation, and a $10 million fine.
Donald Trump pardoned Hayes and his co-founders in March 2025, according to Bloomberg News, without official explanation, despite prosecutors having accused the men of running BitMEX as a “money laundering platform” and treating its U.S. withdrawal as “a sham,” and just months after BitMEX itself paid a $100 million fine for related Bank Secrecy Act violations; Hayes responded on X with a simple “Thank you POTUS.”
Building Maelstrom
Maelstrom is the family office Hayes has led as Chief Investment Officer since December 2022, directing capital into digital assets, DeFi, and early-stage crypto ventures. The fund holds an early stake in Ethena Labs, issuer of the synthetic dollar token USDe, along with positions in Lido and Pendle.
Maelstrom’s work goes beyond managing capital. The fund extended into advisory territory through Hayes’ role at blockchain data company Covalent, taken on in June 2024, and it serves as the platform where Hayes publishes his macro essays, tying his liquidity and monetary policy calls to Maelstrom’s own positioning. Those essays circulate widely among traders.
Arthur Hayes’ Views and Positions
Hayes built his reputation on essays on crypto prices, central bank liquidity, and monetary policy, a framework he has kept current through 2026. In a Cointelegraph interview in June 2026, he explained why he sold his HYPE, NEAR, and Worldcoin positions, arguing an overheated AI market could drag Bitcoin down before liquidity conditions turn back in its favor.
Hayes expanded on that view days later, arguing the AI trade had started to look “less asymmetric” and pointing to oil prices and geopolitics as a bear case the market was not pricing correctly. Speaking on the Bankless podcast on June 22, 2026, he argued Ethereum offered one of the cleaner setups in crypto at the time, and walked through concerns about AI capital expenditure, circular revenue between AI companies, and the depreciation risk on the GPUs powering the sector.
Hayes has returned to that same liquidity argument in broader conversations about what actually backs Bitcoin’s price. In an episode of the Thematic Markets podcast, hosted by Marvin Barth and Mark Farrington, on June 24, 2026, he attributed Bitcoin’s value primarily to global liquidity conditions, monetary policy decisions, and the incentives of sovereign states, a view he has held consistently since his early BitMEX-era essays.
Arthur Hayes’ Net Worth
Arthur Hayes’s 2026 net worth was estimated by Arkham at $200 million to $350 million, with about $42 million in verifiable on-chain holdings. His on-chain portfolio was led by USDC, with additional positions in EtherFi’s EETH and WEETH, as well as ENA, Lido, and Pendle; the rest of his wealth was attributed to BitMEX equity and Maelstrom-related interests that are not fully disclosed.
Arthur Hayes in the News
Arthur Hayes has been active in the market through July 2026, with on-chain data showing a pattern of buying Ethereum on rallies and selling into corrections. Citing Lookonchain data, a wallet linked to Hayes spent roughly $2.53 million to acquire 1,332.5 ETH on July 21, 2026, his second multi-million-dollar Ethereum purchase in a week, part of an accumulation streak that topped 3,270 ETH for the month, as detailed in our report on his latest ETH purchase.
Five days earlier, on July 16, 2026, he had bought 1,293 ETH at similar prices, shortly after selling over $10 million worth of ETH when the asset traded near $1,700.
This isn’t Hayes’ first large ETH move. In August 2025, he made a $8.4 million ETH and DeFi buying spree, snapping up ETH alongside LDO, ETHFI, and PENDLE as Ethereum broke above $4,300, the same pattern of buying into rallies he’s shown again this year.
