Bitcoin miner Poolin files Chapter 11

TLDR

Poolin Technology, once one of Bitcoins largest mining pools, has filed for Chapter 11 bankruptcy in the US to wind down and sell its remaining mining assets.

1. Poolin is seeking court?supervised Chapter 11 protection, listing around $173 million in debt against less than $10 million in assets and a $52 million Texas asset sale plan.
2. The collapse stems from a leveraged mining and lending model hit by Chinas mining ban and the 2022 crypto crash, leaving $163.7 million in unpaid IOUs to about 11,700 wallet users.
3. Direct impact on Bitcoins network is limited, but the case underscores ongoing stress in the mining sector and the risks of using custodial wallet products tied to operators.

Deep Dive

1. Filing Details And Creditor Recovery

Singapore?based Poolin Technology and two US affiliates filed for Chapter 11 in the US Bankruptcy Court for the District of New Jersey, aiming to liquidate remaining assets and cease operations, with liabilities between $100 million and $500 million and total prepetition obligations around $173.1 million. Poolin plans to auction two West Texas mining sites under a $52 million stalking?horse bid from Thor CALAP LLC for its Pyote and Tarbush facilities, subject to court approval and competing bids, as described in its Chapter 11 asset sale plan.

The largest liability block is Poolin Wallet IOUs: roughly $163.7 million owed to about 11,700 users with balances over $100 following the suspension of withdrawals in 2022, according to bankruptcy summaries of wallet IOU obligations. Even if the Texas auction clears above the stalking?horse bid, the estates asset value is far below total claims, so unsecured creditors face partial and slow recoveries.

2. How Poolin Reached Bankruptcy

Poolin was founded in China in 2017 by former Bitmain staff and at its peak controlled nearly 20 percent of global Bitcoin hashrate, before being hit by Chinas 2021 mining ban and forced to migrate operations to the US, particularly Texas, as noted in coverage of its rise and decline in hashrate share.

To grow, Poolin layered a lending and wallet business on top of mining, borrowing against customer crypto and offering interest?bearing deposits. When Bitcoin prices fell sharply in 2022, collateral values dropped, margin calls were triggered, and lenders liquidated pledged assets, leaving Poolin unable to honor withdrawals and forcing it to issue IOU tokens. Operational missteps in Texas (over?ordered equipment, lower?than?expected power allocations) added tens of millions of dollars in losses, culminating in the shutdown of Texas mining operations on 10 July 2026 and the current wind?down strategy.

3. Impact On Bitcoin And What To Watch

Poolins hashrate share had already shrunk before the filing, so its formal bankruptcy changes little at the protocol level: Bitcoins network continues to function, and other pools can absorb any remaining hashrate. The main impact is reputational and structural, highlighting that mining businesses tied to debt, high energy costs, and lending products can be fragile when prices and funding conditions turn.

Observers are watching three things: the final auction price for Poolins power and data?center assets, whether AI and high?performance computing buyers outbid traditional miners, changes in global mining difficulty and hashrate distribution as capacity shifts, and how courts treat the frozen wallet IOUs relative to other creditors.

Conclusion

Poolins Chapter 11 filing marks the formal end of a former top Bitcoin mining pool and crystallizes losses tied to an aggressive, leveraged mining and lending model. The case is unlikely to disrupt Bitcoin itself, but it reinforces that mining economics, debt, and custodial products are tightly linked and can fail together in stressed markets.

Confidence: high multiple court and media reports from 2425 July 2026 align on the filing, liabilities, asset sale plan, and IOU obligations.
