Poolin Files for Chapter 11 as $52M Plan Moves Ahead for Texas Mining Sites

Poolin, the Singapore-based Bitcoin mining pool operator, and two US affiliates have filed for Chapter 11 bankruptcy in New Jersey, according to a court filing reviewed via PACER Monitor. The move arrives as mining businesses continue to grapple with cost pressures—particularly electricity—while some operators look for new revenue streams beyond block production.
Alongside the restructuring process, Poolin is asking the court for permission to sell two West Texas mining sites to Thor CALAP LLC through a proposed stalking-horse bid valued at $52 million. A court-supervised auction would follow, with a bid deadline set for Sept. 8 under the proposed procedures.
Key takeaways

Poolin and two US affiliates filed for Chapter 11 bankruptcy in New Jersey, with liabilities estimated between $100 million and $500 million.
The company is pursuing a $52 million stalking-horse sale of two West Texas mining sites to Thor CALAP LLC.
Under the proposed terms, $37 million would cover Tarbush assets (including assumed liabilities) and $15 million would cover the Pyote site (including power rights and equipment).
The filing suggests a highly constrained balance sheet for a once-dominant pool, now operating at a much smaller share of network hashrate.
The restructuring fits a broader trend: miners seeking survival via liquidation or diversification into AI/data-center infrastructure.

Chapter 11 filing outlines Poolin’s financial position
Poolin’s Chapter 11 court filing, available through PACER Monitor, provides a snapshot of the company’s estimated financial scale. The petition estimates liabilities in the range of $100 million to $500 million, while assets are estimated between $1 million and $10 million. The filing also lists 10,001 to 25,000 creditors.
For investors and industry observers, the wide liability and asset bands underscore the uncertainty that often accompanies mining restructurings—especially for operators with volatile operating expenses, variable energy costs, and exposure to the economics of mining difficulty and Bitcoin prices. While the filing does not provide a definitive balance sheet, the magnitude difference between liabilities and assets signals that creditors may be evaluating a realistic path toward partial recoveries, rather than a straightforward reorganization.
A proposed sale of West Texas capacity is central to the process
Poolin’s bankruptcy filing also centers on a targeted asset sale designed to preserve value while the case proceeds. The company is seeking court approval to sell two mining sites in West Texas to Thor CALAP LLC as a stalking-horse bid totaling $52 million.
The proposed transaction breaks down as follows:

Tarbush assets: $37 million, including assumed liabilities.
Pyote site: $15 million, including power rights, equipment, and other assets tied to the mining facilities.

As proposed, the sale would be subject to a court-supervised auction, with a bid deadline of Sept. 8 under the bidding procedures. For parties watching the case, the auction step is crucial: it can reveal whether other bidders are willing to pay more than the stalking-horse floor, particularly for assets that may include power arrangements and installed infrastructure.
From top pool to smaller hashrate share
Poolin was once described as the world’s largest Bitcoin mining pool. In 2019, it held that position, but the filing-era context reflects a significant shift in the industry landscape. According to Hashrate Index, Poolin currently ranks as the 17th largest mining pool operator by hashrate, with a 0.2% market share.
This matters because a pool operator’s economics are closely linked to volume—both in terms of how much hashing power it attracts and the ability to retain miners during periods of margin compression. When network conditions and operating costs become unfavorable, smaller pools can lose market share faster, which in turn can pressure revenue tied to pooled mining participation.
Restructuring and an AI pivot reshape the mining playbook
Poolin’s filing sits within a wider pattern in the Bitcoin mining sector. Rising electricity costs have pressured mining operations, pushing some companies to shut down and others to seek restructuring to reduce obligations or reallocate resources.
Earlier this year, NFN8 Group and two affiliates filed for Chapter 11 bankruptcy in the Western District of Texas in February, according to a separate report linked in the original coverage. That case illustrates how energy expenses and fixed infrastructure commitments can become difficult to sustain—particularly when mining economics deteriorate.
At the same time, some publicly traded miners have attempted a different approach: converting their power, facilities, and data-center experience into AI- and high-performance computing-oriented ventures. The original reporting noted that in November 2025, Bitfarms initiated a full wind-down of its Bitcoin mining operations as it pivoted toward AI and high-performance computing data centers.
More recently, deals tied to AI infrastructure were highlighted across the sector. Hut 8 and IREN announced large-scale AI infrastructure plans, with Hut 8 moving forward on a 15-year lease for an AI data center campus and IREN disclosing $2.8 billion in cloud services contracts with AI developers. Earlier coverage also pointed to MARA Holdings pursuing plans to acquire a Texas site with up to 2 gigawatts of capacity to expand AI and digital infrastructure.
Industry observers have framed these shifts around a key constraint: the challenge of securing compute resources and the infrastructure needed to support them. In the coverage referenced, Bernstein reportedly said that deals with third-party providers—including Bitcoin miners—will be necessary for AI companies seeking to address computing power limits at AI data centers.
What comes next for creditors and miners watching the auction
Poolin’s Chapter 11 process and proposed West Texas sale will likely become a bellwether for how much value is still attached to mining infrastructure, especially when assets are paired with power rights and installed equipment. Readers should watch the court-approved bidding process leading up to the Sept. 8 deadline and look for updates on whether the auction produces competing offers that change the valuation outlook for Poolin’s remaining operations.
