Bitcoin mining stocks surged as investors view miners as AI infrastructure providers rather than crypto-focused companies.
Hut 8 shares have climbed nearly 600% year-over-year, while TeraWulf has gained around 800%.
IREN led the latest rally with a 13% jump after announcing a $3 billion capital raise.
Bitcoin mining stocks surged sharply this week as investors poured into companies repositioning themselves at the center of the booming artificial intelligence infrastructure market.
Firms once viewed primarily as crypto miners are now being revalued as potential providers of AI and high-performance computing (HPC) infrastructure, driving massive rallies across the sector.
Shares of Hut 8, Cipher Digital, IREN, TeraWulf, and Riot Platforms all posted strong gains during Wednesday’s session, fueled by growing optimism surrounding AI-related data center demand and hyperscale computing expansion.
Hut 8 shares have climbed nearly 600% year-over-year, while TeraWulf has surged roughly 800% annually, as Wall Street increasingly rewards miners shifting away from Bitcoin production toward AI infrastructure.
The rally also coincided with broader strength in US equities, with the S&P 500 reaching fresh record highs and semiconductor stocks continuing their explosive ascent.
The Philadelphia Semiconductor Index has risen nearly 77% this year, reinforcing bullish sentiment around companies tied to AI hardware and cloud infrastructure.
Bitcoin Miners Shift Toward AI and High-Performance Computing
The latest stock surge reflects a broader strategic transformation underway among major Bitcoin mining firms.
Rather than relying solely on crypto mining revenues, many companies are redirecting energy resources, data centers, and capital expenditures toward AI cloud services and hyperscale computing.
IREN led Wednesday’s gains, jumping by 13% to $67.84 after announcing a series of major AI-focused initiatives.
The company recently secured $3 billion in convertible bond financing and partnered with Nvidia to develop a 5-gigawatt AI data center platform.
IREN also completed a $625 million acquisition of software services provider Mirantis, further expanding its cloud infrastructure capabilities.
In another significant development, IREN finalized a $1.6 billion agreement with Dell to supply Nvidia Blackwell AI systems, supporting a cloud contract reportedly valued at $3.4 billion.
Bernstein Research recently highlighted IREN as one of the clearest examples of a Bitcoin miner evolving into an AI infrastructure company.
According to Bernstein analysts, 11 publicly traded Bitcoin mining companies collectively control approximately 27 gigawatts of existing and projected power capacity.
As AI data center demand accelerates globally, analysts believe access to reliable electricity may become even more valuable than semiconductor supply.
This dynamic is positioning miners as strategic infrastructure partners for hyperscalers and AI firms seeking immediate access to power, cooling systems, and operational data centers.
Hut 8 and Cipher Reach Record Highs
Hut 8 and Cipher Digital also extended their bullish momentum on Wall Street, with both companies hitting fresh all-time highs during the trading session.
Cipher Digital shares rose approximately 9.5% to around $25, driven by investor enthusiasm surrounding its long-term hyperscale expansion strategy.
Company filings show Cipher secured several long-term lease agreements with hyperscale customers, including a 15-year partnership with Amazon Web Services.
The firm has also reportedly arranged dedicated financing facilities to support the construction of new AI-focused infrastructure.

Meanwhile, Hut 8 shares climbed nearly 5% to trade close to $118, capping off one of the sector’s strongest annual performances. The company’s stock has gained nearly 600% over the past year as investors increasingly view Hut 8 as an energy infrastructure platform rather than simply a Bitcoin miner.
Hut 8’s transformation has been largely supported by a major AI-focused data center lease agreement with Nvidia. The initial deal is valued at $9.8 billion and could expand to more than $25 billion if renewal options are exercised.
Corporate filings show that Hut 8 is dynamically allocating computing resources between Bitcoin mining and AI workloads based on profitability, reflecting the growing convergence between crypto infrastructure and AI services.
TeraWulf and Riot Expand AI Infrastructure Operations
Other mining companies also benefited from the AI-driven rally. TeraWulf shares gained more than 6% after the company acquired a new site in Kentucky capable of supporting over 1 gigawatt of power dedicated to high-performance computing operations.
Notably, TeraWulf reported that its HPC division generated more quarterly revenue than its traditional Bitcoin mining segment for the first time, underscoring how quickly the company’s business model is evolving.
Riot Platforms rose 3.3% to roughly $27 after reporting $33 million in first-quarter data center revenue, largely driven by its partnership with AMD. The company is expanding its contracted AI infrastructure capacity to 50 megawatts and has partially sold Bitcoin holdings to fund further development.
Despite those sales, Riot still holds approximately $1.2 billion in Bitcoin on its balance sheet. The company’s stock has gained more than 100% year-to-date, even as Bitcoin itself experienced a 13% correction and traded around $75,000 during the same period.
The rapid appreciation in mining stocks suggests investors are increasingly betting that Bitcoin miners could become critical players in the expanding global AI economy, leveraging their massive energy capacity and data center expertise to capture a growing share of the AI infrastructure market.
