CleanSpark and MARA Drop as Bitcoin Mining Equities Lag Behind the Underlying Asset

Bitcoin mining stocks experienced notable declines in morning trading, lagging behind the cryptocurrency they produce. CleanSpark dropped 7% to $10.72, while MARA Holdings fell 5% to $9.89. In comparison, the iShares Bitcoin Trust ETF slipped 1% to $46.54, Strategy declined 1% to $151.76, and the broad-market SPDR S&P 500 ETF Trust eased 0.3% to $775.01.

The divergence reflects a broader annual pattern. Over the past year, CleanSpark has declined 40% and MARA has dropped 51%, whereas the iShares Bitcoin Trust ETF registered a 33% decline over the same timeframe. Operational expenses—such as rising electricity costs, financing requirements, and share dilution—have weighed directly on miner profitability, with CleanSpark's latest reported quarter showing lower year-over-year revenue and a swing from profit to loss.

Unlike pure-play holding entities such as Strategy, which primarily keeps Bitcoin on its balance sheet without direct operating layers, miners bear heavy capital expenditures and equipment depreciation. Both CleanSpark and MARA have also been deploying capital toward artificial intelligence and data center hosting infrastructure to diversify revenue, requiring substantial initial spending.
