MARA Holdings, the world’s largest publicly listed bitcoin miner, has reportedly added 1,000 BTC worth approximately $66.7 million to its treasury, bringing its total holdings to 36,303 BTC.
Onchain analytics platform Lookonchain reported the purchase was executed through the FalconX crypto prime brokerage platform.
A dramatic reversal from Q1 selling
The purchase marks a notable shift for a company that sold over $1.5 billion in bitcoin during the first quarter of 2026.
MARA’s bitcoin stash peaked near 53,822 BTC at the end of 2025, meaning the company has shed roughly a third of its holdings since January.
The single largest sale came in March, when MARA offloaded 15,133 BTC for approximately $1.1 billion.
Those proceeds were used to repurchase convertible senior notes maturing in 2030 and 2031.
The selling wasn’t entirely surprising given that bitcoin had fallen roughly 45% from its record high of $126,080 reached in October 2025.
Pivoting beyond mining
MARA has been diversifying aggressively into AI and high-performance computing infrastructure.
The company deployed AI inference racks at its Granbury, Texas data center and acquired a 64% stake in Exaion, a firm operating HPC data centers.
In November, MARA announced a collaboration with MPLX LP to supply natural gas to planned electricity generation facilities in West Texas, aimed at powering advanced AI workloads.
Financial pressure behind the strategy
In Q1 2026, MARA reported revenues of $174.6 million, an 18% year-over-year decline, alongside a net loss of $1.3 billion driven primarily by unrealized losses on its bitcoin holdings.
The company’s average cost basis sits at approximately $58,635 per BTC. Bitcoin was trading near $66,000 at the time of the reported purchase.
