NEW YORK, July 17, 2026 – MARA Holdings, Inc. (NASDAQ:MARA) closed at $10.69 on Friday, down 6.4% on the day and 15.2% over the past five trading sessions. The sharp decline far outpaced the Nasdaq Composite's weekly loss of roughly 1.4%, and came despite a 0.5% gain in Bitcoin over the same period, suggesting company-specific factors are at play.
Diverging fortunes: MARA vs. CleanSpark
The most telling contrast came from peer CleanSpark Inc. (NASDAQ:CLSK), whose shares rose 1.4% this week after announcing a signed 20-year data-center lease. The five-day return gap between the two stocks widened to 16.6 percentage points. CleanSpark committed 175 megawatts of capacity to a global technology tenant, while MARA's recent Texas announcement cited only tenant interest, not a signed contract.
This divergence offers investors a live test of the market's preference for contracted economics versus potential power. CleanSpark's lease is expected to generate $6.6 billion in total value, with an estimated average annual net operating income (NOI) of about $330 million. That annual NOI represents roughly 10% of CleanSpark's $3.31 billion market capitalization. However, the company estimates landlord costs of $1.75 billion to $2.10 billion, or 53% to 63% of its current market value, underscoring the capital-intensive nature of these deals.
MARA's Texas ambitions remain unsecured
MARA has outlined ambitious plans for its Texas site, expecting up to 1 gigawatt of capacity by October 2027 and up to 2 gigawatts by April 2028. Full energization could lift the company's potential portfolio capacity to roughly 4.8 gigawatts, including the anticipated Long Ridge acquisition. CEO Fred Thiel noted that "sites with access to reliable, scalable power will become increasingly valuable." However, the company still must build and lease the Texas campus, and construction requires regulatory approvals. Tenant interest is not contracted revenue.
The comparison between MARA and CleanSpark is commercial, not physical. MARA's 4.8-gigawatt figure covers potential portfolio capacity, while CleanSpark's 175 megawatts represent one contracted site. The market's reaction suggests investors are demanding signed tenants before assigning value to power access.
Analyst downgrade and broader market context
Piper Sandler analyst Patrick Moley cut his price target on MARA to $13 from $16 on Friday, though he maintained an Overweight rating. The revised target still implies roughly 22% upside from Friday's close. Moley noted that "underlying demand for AI data center tenancy remains largely unchanged," but attributed part of the decline to weaker sentiment around crypto and AI-linked stocks.
Friday also saw a broad technology selloff, with the Nasdaq falling 1.4% as chip stocks slid and oil prices rose. Investors are questioning rich valuations and the sustainability of AI spending growth. Next week, Alphabet Inc. (NASDAQ:GOOGL) reports earnings on Wednesday, July 22. Its prior 2026 capital-spending plan of $175 billion to $185 billion will be closely watched, as any change could reset expectations for data-center demand.
Bitcoin and near-term catalysts
Bitcoin remains the nearer catalyst for MARA and other miners. The cryptocurrency traded near $64,100 after the stock market closed on Friday. Weekend volatility could quickly shift sentiment toward mining stocks, which remain highly correlated with crypto prices.
The week's divergence between MARA and CleanSpark leaves one clear valuation test: turning power access into signed revenue. Until MARA can convert its Texas potential into contracted tenants, the market is likely to remain skeptical.
