Poolin and affiliated companies filed for Chapter 11 bankruptcy on July 22, 2026, after the pool had held the world's largest position in 2019. The filing also proposed a sale of two West Texas sites, anchored by an opening bid of $52 million.

A former leader enters Chapter 11

Poolin's 2019 ranking shows the scale it once achieved in Bitcoin mining. Seven years later, the bankruptcy filing placed the company and its affiliates under court protection while they pursued a sale of physical mining assets. The two West Texas sites and the opening bid give the process a specific asset base and a starting valuation. They do not describe a completed sale of $52 million.

In a bankruptcy sale, a stalking horse sets the initial offer that rival bidders must beat. The verified reporting supports a proposed sale process built around that $52 million opening bid.

Poolin's 2019 leadership and its position in 17th place on July 24 show a wide swing in the pool's ranking. That earlier position described computing power coordinated through Poolin in 2019. The Chapter 11 filing and the proposed sale of two West Texas sites are separate facts about Poolin and its affiliates in July 2026.

A dated snapshot shows how rankings moved

Hashrate Index placed Poolin 17th with 0.2% of hashrate in a July 24 snapshot. That is a dated measurement. It is not a permanent or current ranking. Next to Poolin's position as the world's largest pool in 2019, the snapshot shows how much a pool's share can move.

Mining pools coordinate work and payouts for participating miners. Miners, in turn, can point their machines to a different pool. Poolin's decline fits a market where hashrate can move, though the bankruptcy filing by itself does not prove why every miner changed pools. What it does show is that an early lead did not protect Poolin's later position.

Concentration still deserves attention, because pool operators influence block construction for the hashrate directed to them. A leaderboard is a snapshot, though, not a fixed map of ownership. Even the operator on top has to keep competing for participation, or the ranking moves again.

Why It Matters

Poolin was the world's largest Bitcoin mining pool in 2019, yet Poolin and its affiliates filed Chapter 11 in July 2026 and proposed selling two West Texas sites through a process anchored by a $52 million bid. A July 24 snapshot then placed the pool 17th, with 0.2% of hashrate. Those facts separate past coordination power from permanent control. A leading pool can lose share, and corporate assets can still end up in bankruptcy court. Bitcoin users should watch concentration without treating any single day's dominant intermediary as untouchable.
