Bitcoin-miner Bitmain Faces Federal Investigation Over National Security Issues: Report
Bitmain Technologies Ltd., the Chinese manufacturer behind most of the world’s Bitcoin mining machines, has been the focus of a federal investigation assessing whether its products pose national security risks, according to Bloomberg reporting.
The inquiry, dubbed “Operation Red Sunset,” led by the Department of Homeland Security, reportedly examined whether the company’s machines could be remotely manipulated for espionage or sabotage of critical US infrastructure.
Bitmain denies these capabilities, but investigators have reportedly tested its equipment at ports and dissected chips and code to assess potential threats.
The company’s hardware has long attracted scrutiny.
A 2017 Bitcoin Magazine report suggested Antminer devices contained code allowing remote shutdown, which Bitmain said was a theft-prevention feature later patched. Similar concerns resurfaced in 2019.
In May 2024, then-President Joe Biden blocked a crypto mining facility near a Wyoming nuclear missile base, citing national security risks linked to foreign-sourced mining equipment. The Committee on Foreign Investment in the United States (CFIUS) said the presence of foreign mining devices near sensitive facilities could facilitate surveillance and espionage.
Bitmain has repeatedly stated it complies with US law and has no ties to the Chinese government. It also denied awareness of “Operation Red Sunset” or any import-related investigations.
The Commerce Department blacklisted Bitmain’s AI affiliate, Sophgo Technologies, in January 2025 over alleged dealings with Huawei, further raising concerns about the company’s ties to Beijing.
The investigation intersects with the Trump family’s crypto ventures. Eric and Donald Trump Jr. invested in American Bitcoin, a company that recently acquired 16,000 Bitmain devices for $314 million, paid in Bitcoin, per Bloomberg.
The startup plans to operate 76,000 mining machines across the US and Canada. American Bitcoin insists its operations follow strict security standards and that Bitmain hardware poses no credible risk to the US power grid or national security.
The issue has drawn bipartisan attention. A July 2025 Senate Intelligence Committee report highlighted “disturbing vulnerabilities” in Bitmain devices and warned that facilities using them near power plants or military installations present “an unacceptable risk.”
GOP Representative Zach Nunn also requested CFIUS review specialized chips in foreign mining hardware to assess broader policy implications.
As the US continues to monitor foreign crypto technology, the case underscores the tension between rapidly expanding digital asset industries and national security concerns, especially when high-profile political figures are involved.

Bitcoin Miner TeraWulf (WULF) Stock Jumps 25% on Positive AI News
Shares of TeraWulf (NASDAQ: WULF) jumped more than 25% Tuesday morning after the company announced a pivot to AI.
TeraWulf, one of the largest publicly traded bitcoin miners, is accelerating its shift into artificial intelligence infrastructure through a new joint venture with AI cloud provider Fluidstack.
The companies plan to build 168 megawatts (MW) of high-performance computing capacity at TeraWulf’s Abernathy, Texas, campus under a 25-year hosting agreement valued at roughly $9.5 billion in contracted revenue.
TeraWulf will hold a 51% stake in the venture and retain exclusive rights to participate in Fluidstack’s next ~168 MW project on similar terms. Construction is expected to be completed in the second half of 2026, with the total project costing $8 million to $10 million per MW, the company announced.
To support project financing, Google has committed to back about $1.3 billion of Fluidstack’s long-term lease obligations, improving the credit profile of the joint venture’s debt structure.
No equity issuance or warrants were included as part of the deal.
The announcement expands TeraWulf’s contracted high-performance compute pipeline to more than 510 MW and supports an updated growth strategy targeting 250 MW to 500 MW of new contracted capacity annually.
The company, best known for its bitcoin mining operations, has increasingly leaned into AI-focused data center development amid a market shift toward GPU-based compute demand.
“Securing more than 510 MW of critical IT load in the past 10 months provides a direct proof-point of our growth strategy,” CEO Paul Prager said.
Alongside the expansion, TeraWulf reported preliminary third-quarter revenue of $48 million to $52 million — up roughly 84% from a year earlier — and adjusted EBITDA of $15 million to $19 million.
Leading Bitcoin mining companies are switching over to AI on top of their mining efforts. Firms like Marathon Digital, Riot Platforms, and CleanSpark are seeing strong stock gains but are also pivoting toward Artificial Intelligence and High-Performance Computing (HPC), leveraging their large-scale energy and data infrastructure.
This transition positions miners as emerging technology players beyond cryptocurrency, attracting investor interest.
Other companies, including Core Scientific, Bitdeer, and Hut 8, are following suit — Bitcoin miners are becoming key contributors to the AI-driven digital economy while maintaining exposure to Bitcoin.
According to their website, TeraWulf is a U.S.-based digital asset technology company that owns and operates sustainable data centers for high-performance computing (HPC) and bitcoin mining.
