Marathon Digital Unveils $2B Stock Offering to Boost Bitcoin Reserves Amid Industry Shift

Marathon Digital Holdings (MARA), the second-largest public bitcoin holder, is set to raise up to $2 billion via a new stock sale aimed at significantly expanding its bitcoin portfolio.

In a recent SEC filing, the mining giant disclosed an at-the-market (ATM) equity offering, enabling it to sell shares gradually through top-tier financial institutions like Barclays, BMO Capital Markets, Cantor Fitzgerald, BTIG, and others. The proceeds are primarily earmarked for acquiring more BTC from the open market, in line with the firm’s long-standing “Hodl and accumulate” strategy.

“The funds will support general corporate operations, including strategic bitcoin acquisitions,” Marathon noted in its prospectus.

This initiative builds on a prior $1.5 billion ATM equity program and mirrors the approach popularized by Michael Saylor’s Strategy Inc.—leveraging equity markets to buy BTC rather than relying solely on mining rewards.

Marathon currently holds 46,376 BTC, second only to Strategy’s massive 506,137 BTC cache.

The firm’s decision to favor open-market bitcoin purchases highlights the shifting economics of mining. Last year’s block reward halving has tightened profit margins, making it increasingly cost-effective for miners to supplement their reserves with direct purchases instead of relying exclusively on mined coins.
