Cipher Mining Starts BTC Production at Its 300-Megawatt Black Pearl Data Center

Cipher Mining Launches Bitcoin Production at Texas Black Pearl Facility, Targets 23 EH/s Capacity

Cipher Mining (NASDAQ: CIFR) has begun bitcoin production at its 300-megawatt (MW) Black Pearl data center in Texas, marking a significant expansion of the firm’s mining operations. The New York-based miner announced the launch on Monday, adding Black Pearl as its fifth active site.

Currently, Phase I of the facility is operating at 150 MW and delivering a hashrate of 2.5 exahashes per second (EH/s). Cipher expects output to climb sharply to 9.6 EH/s by the end of the third quarter as it deploys newer, more efficient mining rigs. Ultimately, the company projects its total self-mining capacity will reach 23.1 EH/s when all phases are complete.

Construction of Black Pearl took 16 months. Cipher highlighted careful execution as the key to maintaining lower costs in a volatile mining environment.

“We’re proud to be mining bitcoin ahead of schedule,” said CEO Tyler Page in a statement.

Looking beyond mining, Cipher plans to build out a 2.6-gigawatt (GW) pipeline capable of supporting both bitcoin mining and high-performance computing (HPC) workloads, positioning itself to tap into emerging digital infrastructure opportunities.

Cipher’s expansion comes as public miners compete to grow capacity and remain profitable in the post-halving era, where block rewards are lower and operational efficiency is more critical than ever.

Shares of CIFR fell 6.9% during regular trading on Monday but recovered slightly, posting a 1.9% gain in after-hours trading.
