BitFuFu Inc. filings document foreign private issuer reports for a Bitcoin mining and mining-services business. Its Form 6-K reports furnish operating updates and financial results, including Bitcoin production, Bitcoin holdings, self-mining output, cloud mining output, managed hashrate, fleet efficiency and power capacity under management.
Filings also reference registration statements on Form F-3 and disclose how press-release exhibits are incorporated by reference when applicable. The formal record includes revenue categories such as Cloud Mining Solutions, Self-Mining Operations, Mining Equipment Sales and Hosting Services, along with balance-sheet items including cash, borrowings, pledged Bitcoin and other liquidity disclosures.
BitFuFu Inc. reported unaudited Bitcoin production and operational metrics for April 2026. The company produced 145 BTC in April versus 214 BTC in March, with daily production averaging 4.8 BTC compared with 6.9 BTC in March. Self-mining contributed 32 BTC and cloud mining 113 BTC.
Management cited an unexpected power outage at its Ethiopia facility and a deliberate reduction in third-party hashrate procurement as key headwinds. Total hashrate was 22.4 EH/s in April, down from 25.9 EH/s, while self-owned hashrate held steady at 3.3 EH/s. Bitcoin holdings increased from 1,794 BTC to 1,812 BTC, and average cash-based self-mining cost per BTC was about $59,000.
BitFuFu Inc. presents its 2025 annual report, describing a fast‑growing but highly cyclical Bitcoin mining and cloud‑mining business. Revenue rose from US$284.1 million in 2023 to US$463.3 million in 2024 and US$477.5 million in 2025, driven by expansion in hash rate and hosting capacity.
Cost of revenue also increased, keeping gross margins low at 4.5%, 6.4% and 6.1% for 2023, 2024 and 2025. Net income was US$10.5 million in 2023 and US$54.0 million in 2024, then swung to a net loss of US$31.3 million in 2025 as volatility in Bitcoin prices, fair‑value swings on digital assets and rising operating costs weighed on results.
The company highlights heavy dependence on Bitcoin price, a concentrated supplier base led by Bitmain, significant customer concentration, power cost and hosting risks, security and custody risks around digital assets and stablecoins, and ongoing internal control weaknesses over financial reporting. As of December 31, 2025, BitFuFu had 166,613,948 ordinary shares outstanding and had pledged 274 Bitcoins as loan collateral.

Total hashrate was 25.9 EH/s, including 3.3 EH/s of self-owned capacity and 22.6 EH/s from third-party suppliers and hosting customers. Management noted a modest decline in self-owned hashrate due to disposing of older-generation machines, with plans to refresh capacity using newer, more energy-efficient equipment.
In March, self-mining generated 43 BTC while cloud mining produced 171 BTC. Average fleet efficiency was 17.7 J/TH, and power capacity stood at 457 MW. The company highlighted volatile network difficulty and believes its cloud mining platform can help customers adjust strategies across changing market conditions.
