BitFuFu increases Bitcoin holdings by 66 BTC to 1,454 BTC
BitFuFu added 66 BTC to its treasury in October, lifting its total holdings to 1,454 BTC as of October 31.
That is a 4.8% bump from the 1,388 BTC the company held at the end of September. The miner grew its stack during a month when mining itself got harder.
The Nasdaq-listed company, which trades under the ticker FUFU, disclosed the figures on November 6, 2026, in regulatory filings covering its October operations.
BitFuFu mined 137 BTC in October. That compares with 167 BTC in September, an 18% decline month over month.
The split was close to even. Self-mining contributed 67 BTC and cloud mining contributed 70 BTC.
The company blamed the slowdown on an 11.8% rise in Bitcoin network difficulty during October. Difficulty is the network's built-in thermostat: when more computing power joins the race to validate blocks, the puzzle gets harder, and each machine earns a smaller share of the rewards.
The effect showed up clearly in daily numbers. Average daily production dropped to 4.4 BTC in October, down from 5.6 BTC in September.
BitFuFu's hashrate under management held steady at 19.5 EH/s. Of that total, 3.7 EH/s is self-owned.
One detail worth sitting with: the company added 66 BTC to its holdings in a month when it mined 137 BTC. In other words, less than half of October's production ended up as net growth in the treasury.
CEO Leo Lu addressed this kind of gap directly. He noted that holdings move around based on production tempo, occasional sales, and purchases of capacity, while emphasizing that the company is focused on sustainable growth and a stronger asset base.
BitFuFu's treasury has not moved in a straight line in 2026. Holdings stood at 1,388 BTC in September, and the company had reached a prior peak of 1,855 BTC in May.
So October's gain is a recovery step, not a new high. The stack remains several hundred BTC below where it sat in late spring.
The company itself is relatively young. Leo Lu founded BitFuFu in 2020, and it went public on Nasdaq in March 2024 through a SPAC merger. Based in Singapore, BitFuFu runs cloud-mining services, mines Bitcoin on its own account, and sells mining equipment, all while trying to hold Bitcoin as a long-term treasury asset.
For anyone tracking FUFU, the October report sends two signals that pull in different directions.
The first is about conviction. Growing the treasury by 4.8% in a month when output dropped 18% suggests management is prioritizing Bitcoin accumulation.
The second is about pressure. An 11.8% difficulty jump in a single month is a reminder that miners do not control their own production curve, and BitFuFu's flat 19.5 EH/s hashrate meant it absorbed the full hit.
This is where the cloud-mining side of the business matters. In October, cloud mining produced slightly more Bitcoin than self-mining, 70 BTC versus 67 BTC.
The gap between production and net treasury growth is also worth watching month to month. When less than half of mined Bitcoin sticks around, investors will want to know how much is going to operating costs, how much to sales, and how much to buying new capacity.
Then there is the May benchmark. Climbing back toward 1,855 BTC would signal that accumulation is outrunning the drag from difficulty and expenses.
For now, the takeaway from October is modest but clear. BitFuFu mined less, kept stacking anyway, and ended the month with 1,454 BTC on its books.
