U.S. contract mining firm Core Scientific announced on June 29 an agreement to buy 17,600 next-generation Bitcoin miners from Chinese hardware maker Bitmain Technologies. The Antminer S19 units will be fully installed at Core Scientific's data centers in the United States over the next four months.
Deal Size and Value
Core Scientific did not disclose the exact cost, but based on Bitmain's current pricing – $1,785 per S19 and $2,407 per S19 Pro – the total package likely ranges between $30 million and $42 million. The company said the purchase is for both its own use and on behalf of institutional clients, claiming it is the largest single acquisition of S19 Bitcoin miners by a blockchain hosting firm.
Machine Performance and Profitability
The Antminer S19 series uses Bitmain's latest SHA256 ASIC chips. The standard S19 delivers 95 TH/s with a power efficiency of 37.5 J/TH, while the S19 Pro achieves 110 TH/s (±3%) and 29.5 J/TH. According to mining pool F2pool, at an average electricity cost of $0.05/kWh, the S19 generates about $3.03 profit per day and the S19 Pro earns $4.12 per day. Core Scientific President and CEO Kevin Turner stated that the firm has already received and begun testing the first units, seeing material success in increasing existing hashrate.
Post-Halving Context and Strategic Importance
The purchase comes after Bitcoin's third halving on May 11, which slashed block rewards from 12.5 to 6.25 BTC, cutting miner revenue by 50%. Miners globally are under pressure to upgrade to more efficient hardware to remain profitable. Core Scientific's large-scale order underscores the United States' growing role in Bitcoin mining, as companies invest heavily in next-generation equipment. Bitmain confirmed the deal in a blog post, highlighting the S19 series' superior energy efficiency compared to earlier models.
