Poolin, once ranked as one of the world's largest Bitcoin mining pools, has filed for Chapter 11 bankruptcy in the United States, capping a slide that began with a 2022 liquidity crisis and never reversed. The Poolin bankruptcy places a former pillar of Bitcoin's mining infrastructure into a court-supervised wind-down.
Poolin Technology PTE. LTD filed a voluntary Chapter 11 asset case in the U.S. Bankruptcy Court for the District of New Jersey on July 22, 2026, under case number 3:26-bk-18325, according to the public court docket.

The filing matters because Poolin was not a marginal operator. By September 2019 the company, founded in November 2017, was regarded as the world's largest cryptocurrency mining pool, a restructuring case summary noted.

The case listing names related debtor cases for Lonestar Taproot LLC and Lonestar Dream, Inc., with first-day matters scheduled for July 27, 2026. The proceeding belongs squarely in the Bitcoin category: Poolin's business was coordinating hash power for Bitcoin miners, a core piece of network infrastructure rather than a consumer app.
From the Top of the Mining League to Insolvency
Poolin's decline traces to the fall of 2022. Poolin Wallet announced on September 5, 2022 that it would pause withdrawals, flash trades, and internal transfers to preserve assets and stabilize liquidity, in an official statement.
That freeze left a lasting overhang. The bankruptcy paperwork shows unsecured Wallet Holder IOUs totaling exactly $163,723,500, the legacy liability owed to users caught in the 2022 suspension.
The distress unfolded against a backdrop of structural pressure on mining, including China's May 2021 Bitcoin mining ban, which the debtors' case summary cites as a major precursor to Poolin's collapse. Sovereign moves have since reshaped where hash power lives, with jurisdictions such as Kazakhstan formalizing state-level mining frameworks.
Poolin's fall stands in contrast to a Bitcoin market that has held up. Bitcoin was priced at $65,447, up 0.07% over 24 hours on roughly $25.9 billion in daily volume, meaning the pool failed even as the asset it served traded above $65,000.
Broader sentiment, however, was cautious. The Fear & Greed Index read 28, in Fear territory, even as prices consolidated during a period when Bitcoin held a tight range through July.
What Miners and Creditors Watch Next
The immediate question is asset recovery. Thor CALAP offered separate stalking-horse bids of $15 million for the Pyote assets and $37 million for the Tarbush assets, or $52 million in aggregate, according to the case summary, setting a floor for a court-run sale process.
Set against the IOU liability, that aggregate bid underscores the recovery gap creditors face and explains why counterparties will track the New Jersey docket, the sale hearings, and any competing offers that emerge before confirmation.
For miners, the practical concern is where payout and pool services migrate. Pool instability tends to push hash power toward operators perceived as solvent, a dynamic visible as exchanges expand offerings like KuCoin's KuPool mining service.
The wider signal is measured, not sweeping. Poolin's insolvency reflects damage done in 2022 rather than fresh weakness in Bitcoin itself, but it is a reminder that mining-sector infrastructure can fail even when the underlying network and price remain healthy.
