The world’s largest Bitcoin mining hub is about to get even bigger. A U.S.-based company has placed an order for 50,000 Avalon A15 Pro rigs from Canaan Inc., marking the manufacturer’s biggest sale in more than three years.
The client’s identity remains undisclosed, but the scale of the purchase underscores how institutional miners are doubling down despite record network difficulty.
Founded in Beijing in 2013, Canaan has become a central supplier of mining hardware to industrial operators. CEO Nangeng Zhang called the deal a show of confidence in Bitcoin’s long-term trajectory, stressing that efficiency gains are now essential to remain competitive.
Difficulty Surges to New Highs
Bitcoin mining has never been tougher. The network’s difficulty – which adjusts roughly every two weeks to reflect the combined computing power of miners – reached 150.84 trillion on Thursday, climbing sharply from 127.6 trillion in August and 134.7 trillion in early September. This makes each block harder to win, squeezing smaller participants and raising the bar for profitability.
The United States currently commands around 36% of the global Bitcoin hashrate, according to the Hashrate Index, cementing its position as the epicenter of mining. With demand for cutting-edge rigs accelerating, Canaan’s massive order reflects the arms race underway among U.S. operators.
Industry in Transition
Not all miners have been able to keep pace. In June, Bit Digital announced it would shut down its Bitcoin operations and pivot toward building an Ethereum treasury. Its CEO warned that another halving – the programmed event that cuts block rewards in half every four years – could make traditional mining unsustainable for many.
At the same time, concentration of mining power is increasing. The Miner Mag reported that four publicly traded firms – Marathon Digital, Iris Energy, Cango, and CleanSpark – together captured just over 19% of all block rewards in July. That consolidation shows how scale has become the key advantage in an industry once defined by hobbyists and small collectives.
Solo Miners Still Find Openings
Yet even in an environment dominated by corporate giants, individual players occasionally beat the odds. One solo miner managed to secure block 903,883 in July, walking away with nearly $350,000 in rewards and fees – a rare reminder that decentralization still has teeth.
For large-scale operators, though, the game is about horsepower and efficiency. Canaan’s latest sale suggests that the biggest players aren’t retreating from Bitcoin’s escalating challenges – they’re preparing for the next cycle by expanding capacity at a historic pace.
