Poolin Files for Chapter 11 Bankruptcy: What Happens Next

Singapore-based Bitcoin mining pool Poolin and two of its US affiliates filed for Chapter 11 bankruptcy in a New Jersey court. It marks the end of an era for a company that was the world's largest Bitcoin pool back in 2019 and now controls just 0.2% of the network's hashrate. For participants who pointed their hashrate at the pool, the case means becoming a creditor in a court proceeding.

What Happened to Poolin?

On Wednesday, Poolin and two of its US subsidiaries filed for creditor protection under Chapter 11 of the bankruptcy code. Court filings estimate the company's liabilities at between $100 million and $500 million, while assets total only $1 million to $10 million. The number of creditors in the case ranges from 10,001 to 25,000.

The company was founded in 2014 and spent years as one of the industry's largest pool operators alongside Antpool and F2Pool. Its market share had been shrinking gradually over the past several years before hitting its current low.

At the same time, the company filed a motion to sell two mining sites in West Texas to Thor CALAP LLC. This is a so-called stalking-horse sale, where a pre-agreed bid sets the floor price for a court-supervised auction that follows.

How Does Chapter 11 Work in This Case?

Chapter 11 doesn't mean immediate liquidation. It gives a debtor time to restructure under court protection while it looks for a buyer for its assets or works out a repayment plan for creditors. For Poolin, that plan centers on selling two sites. Tarbush was valued at $37 million including assumed liabilities, and Pyote, with its power rights and equipment, at $15 million.

Under this kind of deal, the initial bidder usually gets a small payout if someone else outbids them at auction and takes the assets instead. That gives an owner an incentive to step forward first, while still protecting creditors, since the real market price of the sites gets tested through open bidding rather than a private deal.

Why Did a Former Leader Fall So Far?

Poolin topped the Bitcoin mining pool rankings back in 2019. Today, according to analytics services, the company ranks just 17th, with a market share of roughly 0.2%. That decline stems from years of rising electricity costs, which have squeezed mining companies and pushed some to shut down or look for new revenue streams. The April 2024 halving played a role too, cutting the block reward in half and immediately raising production costs for operators running older or less efficient hardware. Pools that hadn't upgraded their ASIC fleets before the network's next difficulty cycle ended up in the weakest position.

Poolin isn't alone in facing these pressures. In February, NFN8 Group and its affiliates also filed for Chapter 11 in Texas. Other operators are taking a different route. Bitfarms wound down its Bitcoin mining entirely to pivot to AI infrastructure, while Hut 8 signed a 15-year, $9.8 billion lease for an AI data center.

What Happens to the Assets and Creditors?

That large creditor count comes down to the nature of the business. Thousands of small and mid-sized miners around the world had joined the pool, and the company owed them regular payouts of their share of mined coins. All of them are now formally creditors in the bankruptcy case.

Lawyers who handle similar cases usually advise pool participants to move their hashrate to another service ahead of time rather than wait for a court ruling. That won't guarantee recovery of payouts already owed, but it at least protects future earnings from further delays.

From here, the process should follow a fairly standard playbook for a US bankruptcy involving assets of this type.

• Point: the court will approve the auction procedure and set a deadline for competing bids on the Texas sites.
• Creditors will file their claims, and the court will determine the order of payouts based on their status.
• If the auction succeeds, proceeds from the sale will go toward partially repaying the company's debts.
• The gap between total liabilities and expected sale proceeds means smaller creditors are unlikely to be made whole.

Mining companies typically sell part of their coin output through centralized exchanges, so a large pool exiting the market also shifts the supply of Bitcoin that miners route through crypto exchanges.

What This Means for the Mining Industry

Poolin's story shows how quickly even a former market leader's position can unravel. Rising electricity costs and tougher competition for hardware are making traditional Bitcoin mining less profitable for operators who haven't upgraded their equipment or diversified their business.

For the industry, it's another signal that some companies will be forced to consolidate with larger players, or, like Bitfarms and Hut 8, look for revenue beyond pure Bitcoin mining. Mining stopped being just a story about cheap power and strong hardware a while ago; the operators who survive now are the ones able to shift their business model quickly.

The coming months will show whether Poolin finds a buyer for its Texas assets or whether the court ends up deciding the outcome alone. For the thousands of small miners who trusted the company with their hashrate, the main question is how much of what they're owed they'll actually get back.
