Comparing CleanSpark and MicroStrategy: Two Bitcoin-Linked Investment Options
For investors keen on gaining Bitcoin-related exposure without owning the cryptocurrency directly, CleanSpark (CLSK) and MicroStrategy (MSTR) are two noteworthy choices. While both stocks are sensitive to Bitcoin price changes, their operational focus is quite distinct. CleanSpark is primarily a Bitcoin mining entity, whereas MicroStrategy functions primarily as a substantial holder of Bitcoin, underpinned by its software operations.
Let’s delve into their fundamentals, growth prospects, and the challenges they face in the market to see which might present a more appealing investment opportunity.
CleanSpark specializes in Bitcoin mining, utilizing energy-efficient data centers. The company’s recent performance highlights a boost in its Bitcoin output. In fiscal 2025, CleanSpark mined 7,873 Bitcoins, marking a 10.9% increase compared to the previous year. The average return per Bitcoin approached $98,000, reflecting a significant 55% rise year over year. Consequently, CleanSpark’s financial performance for the fiscal year continued to be strong, with revenues soaring by 102.2% to $766.3 million. Their profit of $1.12 stands in stark contrast to the loss of 69 cents reported in 2024.
The firm has been ramping up its hashrate by expanding its facilities, upgrading to better machinery, and enhancing its energy sourcing. With more than 1.3 gigawatts of power and land across various states including Georgia, Mississippi, Tennessee, New York, and Texas, CleanSpark’s average hashrate reached 45.6 exahash/second as of September 30, 2025, a notable increase from 27.6 EH/s a year earlier.
That being said, the capital-intensive nature of Bitcoin mining is a considerable concern. CleanSpark needs to continually invest in equipment, infrastructure, and energy to maintain growth in its hashrate. This often necessitates issuing new shares or accruing debt, which could dilute the value for existing shareholders. In early November 2025, the company raised $1.15 billion via a convertible bond issue, sparking fears about potential stock dilution.
Nevertheless, CleanSpark is shifting from being solely a Bitcoin miner to diversifying into digital infrastructure and artificial intelligence (AI) data centers. By leveraging its existing assets, such as power resources and land, the company is setting up advanced data centers aimed at the fast-growing AI and HPC sectors.
This transition appears quite strategic, allowing CleanSpark to tap into long-term growth avenues that aren’t solely reliant on Bitcoin price fluctuations. With a dual focus on Bitcoin mining and AI infrastructure, CleanSpark aims for more stable growth in the long run, thus reducing the risk for future revenue streams.
On the other hand, MicroStrategy has evolved from a software analytics company into a major player in Bitcoin holdings. Their long-term vision centers on a strong Bitcoin treasury and a disciplined approach to accumulation. As of October 26, 2025, MicroStrategy possessed around 640,808 Bitcoins, which amounts to about $71 billion, positioning it among the largest corporate Bitcoin holders globally.
This strategy has yielded a 26% BTC return year-to-date, contributing around $12.9 billion to their profits, underscoring the efficacy of their financial strategy. With an anticipated BTC yield target of 30% for 2025, the company remains committed to creating long-term value.
The uptick in MicroStrategy’s Bitcoin reserves is bolstering its financial output. In its third-quarter results for 2025, year-over-year sales increased by 11% to $128.7 million, and earnings per share jumped to $8.42, a considerable recovery from last year’s loss of $1.72.
MicroStrategy’s software segment is showing consistent growth, providing a sound foundation for its Bitcoin strategy. The company’s Q3 2025 double-digit revenue growth was mainly fueled by the rising demand for analytics solutions and expanding customer adoption.
Moreover, subscription services saw a remarkable 65% year-over-year increase, indicating a successful shift toward higher-margin recurring revenue and reducing dependence on one-time sales.
By enhancing its software offerings along with its Bitcoin strategy, MicroStrategy is solidifying its long-term value. This growth not only diversifies revenue streams but also helps mitigate the volatility typically associated with digital asset holdings.
According to the Zacks Consensus Estimate, CleanSpark appears to have a brighter sales outlook compared to MicroStrategy in the near future. The consensus for CleanSpark’s fiscal 2026 revenue stands at $1 billion, indicating a potential growth of 30.8% year over year.
Conversely, revenue projections for MicroStrategy are estimated to be $473.1 million and $496.1 million for 2025 and 2026, respectively. This suggests minimal year-over-year growth of just 2.1% for 2025 and 4.9% for 2026.
Year-to-date, CleanSpark’s stock has surged by 47.9%, contrasting sharply with MicroStrategy’s 39.2% decline.
When it comes to valuations, CleanSpark’s trailing 12-month price-to-sales (P/S) ratio stands at 3.47x—a stark contrast to MicroStrategy’s 100.19x.
Both companies provide strong exposure to Bitcoin, but CleanSpark seems to offer faster growth prospects, more appealing valuations, and a clearer strategy for diversification through AI and HPC initiatives. MicroStrategy’s slowing sales growth and hefty valuation make it less attractive by comparison. Overall, CleanSpark appears to have more upside potential in the long run when weighing risks and current valuations.
Presently, both CleanSpark and MicroStrategy hold a Zacks Rank of #3 (Hold).
