Bitcoin Mining Stocks Decline Amid Microsoft's AI Data Center Withdrawal

According to Cointelegraph, Bitcoin mining stocks have experienced a downturn following reports that Microsoft has decided to halt its plans for new artificial intelligence data centers in the United States and Europe. This decision, attributed to concerns over a potential oversupply, was reported by Bloomberg and supported by data from Google Finance. The shares of several cryptocurrency mining companies, including Bitfarms, CleanSpark, Core Scientific, Hut 8, Marathon Digital, and Riot, saw declines ranging from 4% to 12% in response to the news. The retrenchment in stock prices underscores the growing reliance of cryptocurrency miners on business from artificial intelligence models, particularly after the Bitcoin network's halving in April 2024, which reduced mining revenues. Coin Metrics highlighted in a March report that miners are diversifying into AI data-center hosting to expand revenue and repurpose existing infrastructure for high-performance computing. Core Scientific, for instance, committed 200 megawatts of hardware capacity in June 2024 to support CoreWeave's AI workloads. Additionally, asset manager VanEck projected in August 2024 that Bitcoin mining stocks could collectively see a significant increase in market capitalizations, estimated at around $37 billion, if they invest heavily in AI support. Despite these potential gains, miners have faced challenges this year due to declining cryptocurrency prices, which have exacerbated pressures on businesses already affected by the April halving, as noted by JPMorgan in March. The diminishing demand for AI data centers could further strain these companies. Analysts at TD Cowen reported on March 26 that Microsoft had abandoned plans to construct several new data centers, which would have generated approximately 2 gigawatts of power, according to Bloomberg. This decision was attributed to a perceived oversupply of computing capacity for AI models and Microsoft's choice to forgo certain planned collaborations with OpenAI, the maker of ChatGPT. Over the past six months, Microsoft has canceled various data center leases and postponed plans to increase capacity, as reported by Bloomberg. The tech giant's investments in data centers are anticipated to slow further in the latter half of 2025 as it completes $80 billion in planned buildouts and shifts focus to equipping existing centers with hardware and equipment. This strategic pivot reflects Microsoft's adaptation to changing market conditions and its reassessment of AI infrastructure needs.
