Bitcoin mining stocks rallied Tuesday as Wall Street’s semiconductor boom extended into the crypto sector, with investors betting that miners’ power-heavy infrastructure can serve the emerging AI infrastructure market.
TeraWulf (WULF) jumped as much as 17% on news of a Kentucky data center acquisition. Hut 8 (HUT), IREN (IREN), and Riot Platforms (RIOT) each closed more than 5% higher. The S&P 500 hit fresh record highs above 7,500, while the Philadelphia Semiconductor Index surged 5.6% on the day and is up nearly 77% year-to-date.
The rally reflects a structural shift in how Wall Street views Bitcoin mining companies. Rather than betting solely on Bitcoin price appreciation, investors are now pricing in a secondary revenue stream: selling electricity and data center capacity to hyperscalers and AI companies building out high-performance computing infrastructure.
Bernstein research identified the bottleneck driving this pivot. Access to reliable electricity, not semiconductors, is emerging as the primary constraint for scaling AI infrastructure. That positioning gives Bitcoin miners a strategic advantage. Eleven publicly traded Bitcoin miners control a current and projected power portfolio of roughly 27 gigawatts, according to Bernstein analysis.
IREN exemplifies the trend. The large-scale miner recently agreed with Microsoft on an AI cloud infrastructure partnership. Bernstein estimates the deal represents a $3.7 billion annualized revenue run rate for IREN’s AI cloud infrastructure business.
The shift reflects deeper economics. Bitcoin mining operations require massive, reliable power supplies and cooling infrastructure. Those same assets can support AI training, inference, and other compute-intensive workloads. Rather than stranding assets during Bitcoin price downturns, miners are now monetizing their infrastructure across both use cases.
The semiconductor-driven market surge on Tuesday extended naturally into this thesis. If chip supply is constrained but power capacity is available, miners holding gigawatts of capacity become essential infrastructure partners rather than cyclical commodity producers.
Whether this pivot sustains depends on execution. Miners must successfully transition operational expertise from Bitcoin validation to AI workload management. The Microsoft deal with IREN suggests at least one hyperscaler views the transition as viable. Broader adoption by other cloud providers would validate the sector’s new positioning.
