Arthur Hayes (born 1985) is an American entrepreneur, co-founder, and former CEO of the cryptocurrency exchange BitMEX (Bitcoin Mercantile Exchange). He is also the Co-founder of 100x Group and a Chief Investment Officer at Maelstrom. He is based in Hong Kong. 
Early Life & Education
Arthur Hayes was born in Detroit, Michigan, USA, to middle-class parents who worked for General Motors (GM). He attended Nichols School, a private preparatory school in Buffalo, New York, where he played varsity tennis and was a varsity cross-country runner. He graduated second in his class in 2004. His family relocated to Buffalo after searching for a school that they felt would provide the ideal learning environment for him as a student and an athlete. Hayes has since created scholarships for students to experience the same quality education he received at Nichols. His mother, Barbara Hayes, said, "Nichols gave him the setting, the stimulation, and at one point, the scholarship to thrive." 
In 2006, Hayes attended HKUST Business School in Hong Kong. He graduated from the University of Pennsylvania, Wharton School of Business in 2008 with a Bachelor of Science in Economics, Finance. 
Hayes was awarded a graduate scheme contract at Deutsche Bank where he worked in the London office before moving to Hong Kong to continue his investment banking career. He worked for Deutsche Bank, from 2008-2011 as an equity derivatives trader and associate. In 2011, Hayes left Deutsche Bank and began working as a Delta One Trader for Citibank in Hong Kong until May 2013. 
Arthur Hayes partnered with Oxford-educated mathematician/Software Developer Ben Delo and Programmer/Crypto enthusiast Samuel Reed to co-found the crypto exchange BitMEX in 2014. They looked to build "the best peer-to-peer trading platform to compete directly with Coinbase, Binance, and Coinmama". They built a complex system using leveraged contracts, quanto futures, and perpetual swaps. This allowed users to trade Bitcoin as they would be able to trade any other derivative, as he said in 2015:
“I wanted to create a more professional exchange for people to trade Bitcoin, when I started trading in 2013 there was nothing like this”. 
Bitmex operates as a market maker and holds Bitcoin on behalf of companies that are hesitant to accept the cryptocurrency on their balance sheet or as a method of payment due to the risk of price volatility. Bitmex has built one of the most complex trading systems which has attracted investors to its exchange. On its first day, the exchange made $50 million in trading, and in the first year of trading, it generated over $1 billion in income. 
“We’re moving from an analog society in terms of money transfer to a digital one, that’s going to be hugely disruptive. And I saw a chance with Bitcoin and crypto to actually create a company that could benefit from this hugely chaotic transformation. And the great thing about Bitcoin is it’s permissionless. There’s a piece of software; me and my co-founders saw we had a business model; we didn’t have to ask permission to build this, and what other industry could three guys go and try to build an exchange that does billions of dollars a day turnover” – Hayes in an interview with the Forkast podcast in August, 2020. 
In December 2019, BitMEX and its CEO were sued for USD 300 million by Frank Amato, a former JPMorgan Chase commodity derivatives trader, and RGB Coin Ltd., who claimed to have been the first seed investor of BitMEX in 2015. According to the suit, the initial USD 30,000 investment was supposed to later be converted into equity, but they weren’t granted the equity, the report added. In January 2021, the lawsuit was closed, with one attorney claiming it was settled out of court. 
In October 2020, Hayes and his business partners were accused by the United States Commodity Futures Trading Commission (CFTC) of violating the Bank Secrecy Act by failing to implement and maintain an adequate anti-money laundering program. Six months later, in April 2021, Arthur Hayes surrendered to United States authorities in Hawaii. He was released after posting a $10-million bail bond pending future proceedings in New York. 
In August 2021, BitMEX agreed to pay up to $100 million to resolve the case from CFTC, and the Financial Crimes Enforcement Network (FinCEN). In the announcement, the CFTC said the U.S. District Court for the Southern District of New York had entered a consent order for HDR Global Trading Limited, 100x Holding Limited, ABS Global Trading Limited, Shine Effort Inc Limited, and HDR Global Services Limited to be charged with illegally operating the BitMEX platform. 
In February 2022, Hayes and BitMEX co-founders pleaded guilty to not having an anti-money laundering program. Being a first-time offender with a charitable history, Hayes received a sentence of six months of home confinement, two years of probation, and a $10 million fine, reflecting his gains from the offense. 
Arthur Hayes co-founded the 100x Group in July 2020 and served as its CEO until October 2020. The 100x Group is a holding company that comprises HDR Global Trading, the parent company of BitMEX. The group was established with the mission of reshaping the digital financial system into a more inclusive one. 
In December 2022, Arthur Hayes became a Chief Investment Officer (CIO) at Maelstrom, A Hayes family office fund, investing in products, infrastructure, and services. In March 2023, Hayes posted on Linkedin:
Arthur Hayes voiced concerns about the arbitrary nature of punishments in the United States, using the $4.3 billion settlement paid out by Binance as an example. In his blog post on November 28, 2023, Hayes argued that the treatment of Binance and its former CEO, Changpeng Zhao (CZ), underscores the system's unfairness. Hayes highlighted Binance’s role in allowing everyday people to own intermediaries and cryptocurrency assets without needing traditional players. 
"Never before had people been able to own a piece of an industrial revolution in under ten minutes via desktop and mobile trading apps"
Hayes argued that the establishment’s financial and political powers felt threatened by intermediaries like Binance, which enabled individuals to bypass traditional institutions and participate directly in the crypto revolution. 
“Obviously, the treatment of CZ and Binance is absurd and only highlights the arbitrary nature of punishment at the hands of the state.”
Hayes encourages readers to consider investing in cryptocurrencies, particularly Bitcoin (BTC), after witnessing the immense energy directed toward penalizing CZ and Binance.
"If you don’t want to get the fuck long Bitcoin and other cryptos after seeing how much energy the state brought to bear on CZ and Binance, I don’t know what else you need to see." - Hayes wrote in his blog
On December 1, 2023, Arthur Hayes tweeted:
"It’s December and I don’t know about you but I’m ready for an old white man to give me some gifts. JAYPOW cut the fucking rates and send $BTC 2 Da Moon!" - Arthur Hayes 
Hayes is eagerly anticipating Federal Reserve Chairman Jerome Powell's upcoming speech. He jokingly referred to it as a possible "gift" from an "old white man." Hayes is hopeful that Powell will make a bold move by slashing interest rates. He believes that such a decision could propel Bitcoin to unprecedented heights. 
Hayes has also previously expressed bullish views on Bitcoin. On November 25, 2023, he shared his thoughts on X (fka Twitter) alongside a chart depicting net reverse repurchase agreement (RRP) and treasury general account (TGA) balance changes, Hayes referred to United States Treasury Secretary Janet Yellen as “Bad Gurl Yellen”. 
"Getting my feet did and observing how Bad Gurl Yellen is busy pumping financial assets. Don’t get distracted, $ liquidity is increasing and $BTC will go up as well. This is the chart of net RRP and TGA balance changes"
In the X post, Hayes encouraged fellow Bitcoin enthusiasts to stay focused, highlighting a significant uptick in U.S. dollar liquidity. He suggested BTC will likely mirror the rise in dollar liquidity, leading to an increase in its price. 
In a December 22, 2023 blog post, Arthur Hayes shared his opinion on Spot Bitcoin ETFs. He explained that Bitcoin has value because “it moves.” However, spot Bitcoin ETFs are made to “vacuum up assets” and “store them in a metaphorical vault,” he said. 
"Imagine a future where the largest Western and Chinese asset managers hold all the Bitcoin in circulation. This happens organically as people confuse a financial asset with a store of value. Because of their confusion and laziness, people purchase Bitcoin ETF derivatives rather than buying and hodling Bitcoin in self-custodied wallets. Now that a handful of firms hold all the Bitcoin, and have no actual use for the Bitcoin blockchain, the coins never move again. The end result is miners turn off their machines as they can no longer pay for the energy required to run them. Bye-bye, Bitcoin!"
Hayes imagined a scenario unfolding where a new cryptocurrency monetary network would take Bitcoin’s place and expand upon Satoshi Nakamoto’s original vision of peer-to-peer electronic money.
"It is beautiful when you think about it. If Bitcoin becomes just another state-controlled financial asset, it dies because it isn’t used. The death of Bitcoin then creates space for another crypto monetary network to grow in its place. This network could just be a reboot of Bitcoin or something different that is an improved adaptation of the original Bitcoin. Either way, the people will once again have a non-state-controlled monetary asset and financial system. Hopefully, the second time around, we will learn not to hand our private keys to the baldies." - he concluded 
Hayes explained that while Tether has configured itself to be a great product in the crypto market, it has only achieved its status due to the refusal of the U.S. banking system to offer a similar product. 
"The people who own Tether make something like $4 or $5 billion in free cash flow every year. It’s basically an interest rate: they basically take dollars, stuff it in a bank account, and then they go buy treasury bills and they earn the spread."
He foresees a possible disruption, as banks might eventually enter the market with their digital currencies. Hayes predicted that once banks recognize the profit potential in this domain, they will quickly move to dominate it, leveraging their existing infrastructure and customer trust. He said that once banks are given the green light to engage with the digital assets sector, they have the necessary comprehensive financial networks and regulatory compliance frameworks to hit the ground running. 
“At the end of the day, they don’t have any defensible business because they rely on the banks to custody their funds and allow them to trade dead instruments,” - he concluded.
