Insights

Data center & crypto operations analyst

CleanSpark reports solid October mining output and meaningful AI/HPC infrastructure moves, combining cash generation with new capacity commitments.

Bitcoin production remained material with 612 coins in October and year-to-date production of 6,537, supported by an Operational Hashrate of 50 EH/s and an average operating hashrate of 46.6 EH/s. The company holds 13,033 BTC (with 5,444 posted as collateral/receivable), and disclosed total USD proceeds from BTC sales of $64,921,047 at an average sale price of $110,057 per bitcoin, which demonstrates active monetization of mined inventory while retaining a sizeable treasury.

Concurrently, CleanSpark announced tangible steps into AI/HPC: hiring an AI data center lead, selecting Submer as an infrastructure partner, acquiring 271 acres and securing 285 MW of long-term power near Houston, and reporting 808 utilized MW with 1.31 GW under contract. Those items show capital deployment and supply agreements that link operational cashflow from mining to data-center expansion, but their ultimate returns depend on execution, build timelines, and the pace of data-center commercialization.

Watch near-term milestones: construction permits, power delivery timelines for the 285 MW Houston site, integration milestones with Submer, and monthly hashrate/production trends through Q1 2026. Those items will confirm whether cash from mining sustains the stated AI/HPC expansion and whether utilisation of contracted GW rises beyond the current 808 MW level.

Monthly bitcoin production of 612, contracted power grows 28%

First month of FY26 includes business evolution with key AI and HPC announcements

LAS VEGAS, Nov. 4, 2025 /PRNewswire/ -- CleanSpark, Inc. (Nasdaq: CLSK), America's Bitcoin Miner® (the "Company"), today released its unaudited Bitcoin mining and operations update for the month ended October 31, 2025.
