Key Takeaways
- Poolin filed Chapter 11 bankruptcy in New Jersey with estimated liabilities ranging from $100 million to $500 million.
- The mining pool operator seeks court approval to sell two Texas sites for $52 million under a stalking-horse bid, with an auction possible.

- Rising electricity costs and financial pressure are forcing Bitcoin miners to restructure or pivot toward AI infrastructure.
What Happened
Poolin, once the world's largest Bitcoin mining pool, filed for Chapter 11 bankruptcy in a New Jersey court. The Singapore-based operator declared liabilities of up to $500 million against assets of just $1 million to $10 million. The company now seeks court permission to sell two West Texas mining facilities under a $52 million stalking-horse bid from Thor CALAP LLC. If approved, an auction will follow, with a bid deadline of September 8. The filing marks a stunning reversal for a pool that dominated Bitcoin mining in 2019, now reduced to a 0.2% hashrate share and a 17th-place ranking.
The Numbers
Poolin's bankruptcy filing reveals a massive gap between obligations and resources. The stalking-horse bid breaks down as $37 million for the Tarbush assets—including assumed liabilities—and $15 million for the Pyote site, covering power rights, equipment, and related assets. The pool's current hashrate stands at a negligible 0.2% of the Bitcoin network, a steep decline from its peak. With between 10,001 and 25,000 creditors, the bankruptcy process is likely to be complex and contested.
Why It Happened
Rising electricity costs and shrinking mining margins have battered Bitcoin miners globally. Poolin's collapse is part of a broader industry shakeout. In February, NFN8 Group also filed for Chapter 11, while other miners have pivoted to AI and high-performance computing to survive. Bitfarms wound down its Bitcoin mining operations entirely in November 2025, and Hut 8 and IREN recently announced multibillion-dollar AI data center deals. The pressure on traditional mining models has forced once-dominant players to restructure or exit entirely.
Broader Impact
Poolin's bankruptcy signals deepening stress in the Bitcoin mining sector and may accelerate consolidation. Distressed assets like the Texas sites could be snapped up by larger, well-capitalized rivals or AI-focused entities, reshaping the mining landscape. The shift toward AI infrastructure blurs the lines between crypto mining and high-performance computing, raising questions about the future of dedicated mining pools and network security if hashrate concentrates further.
What to Watch Next
- Court approval of the $52 million stalking-horse bid and a potential auction with a September 8 deadline for competing offers.
- Whether other mid-sized mining pools follow Poolin into restructuring or pivot to AI, following the path of Bitfarms and Hut 8.
- Bitcoin network hashrate distribution shifts and their impact on decentralization if consolidation accelerates.
