MARA Holdings, formerly Marathon Digital Holdings, has reached a new all-time high in Bitcoin mining revenue, fueled by Bitcoin’s recent surge to a record price. The company’s annualized mining revenue exceeded $752 million on May 27, according to data from CryptoQuant, making it the most profitable day in the company’s history. Marathon is currently the world’s largest publicly traded Bitcoin ( BTC ) mining firm by market capitalization. “Quarterly reports are slow. Onchain shows revenue in real time,” CryptoQuant founder and CEO Ki Young Ju wrote in a May 27 X post confirming the milestone. Marathon’s record revenue surge occurred days after Bitcoin rose to a new all-time high of $112,000 for the first time on May 22, a development attributed by some analysts to Japanese bond market turbulence, which saw bond yields rise to new highs amid economic turbulence in the country.
