Cipher Mining Commences Bitcoin Output at New 300 MW Black Pearl Center

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

Cipher Mining (NASDAQ: CIFR) has started bitcoin production at its newly built 300-megawatt (MW) Black Pearl data center in Texas, marking a significant step forward in its expansion plans.

Announced Monday, the launch brings Cipher’s total operational sites to five. The initial phase of Black Pearl is running at 150 MW, delivering a current hashrate of 2.5 exahashes per second (EH/s). Cipher anticipates ramping this up to 9.6 EH/s by the end of the third quarter as it deploys new, more efficient mining rigs to replace older equipment. Ultimately, the company projects it will reach a total self-mining capacity of 23.1 EH/s once the facility is fully operational.

The Black Pearl site took 16 months to complete, with Cipher crediting its disciplined approach for keeping costs in check despite the challenging environment for miners.

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

Looking beyond bitcoin, Cipher has its sights on high-performance computing (HPC), planning to develop a 2.6-gigawatt (GW) pipeline that could support both mining and emerging AI workloads.

The company’s aggressive expansion comes amid rising competition in the post-halving mining landscape, where efficiency and scale have become critical for maintaining profitability as bitcoin block rewards decline.

Cipher Mining shares closed down 6.9% on Monday but clawed back some losses in after-hours trading, gaining 1.9%.
