The Bitcoin mining industry is undergoing a paradigm shift in 2026. While BTC has declined approximately 12% year-to-date, the top ten publicly listed mining firms have seen their stock prices surge between 25% and 73%. The leader, Terawulf (NASDAQ: WULF), soared 73.58%. This outperformance is not from mining Bitcoin, but from pivoting to AI and high-performance computing (HPC) infrastructure.
Terawulf Sets the Benchmark with $12.8B AI Deal
Terawulf secured over $12.8 billion in HPC contract revenue through long-term leases with Google-backed Fluidstack and Core42. The firm now has more than 1GW of available power across its Kentucky and Maryland facilities, with HPC contributing over half of its annual revenue. This strategic shift has rewarded Terawulf with the highest stock gain among its peers.
Hut 8, Core Scientific, and Others Follow Suit
Hut 8 (NASDAQ: HUT) signed a $7 billion, 15-year lease with Anthropic and Fluidstack, with a total pipeline of 8.5GW. Core Scientific (NASDAQ: CORZ) booked $10–12 billion in contract revenue via its Coreweave partnership, with analysts expecting 70% of 2026 revenue from HPC. Applied Digital (NASDAQ: APLD) secured $11 billion in agreements, and IREN targets 71% HPC revenue by year-end through a partnership with Microsoft. Cipher Digital (NASDAQ: CIFR) has completely exited Bitcoin mining, pivoting to a $9.3 billion HPC backlog including AWS and Google contracts.
The AI Race Among Mining Firms
Not all miners have fully transitioned. MARA Holdings and Riot Platforms gained 29.56% and 47.04% respectively, both pursuing AI expansion. Bitdeer (NASDAQ: BTDR) lagged with a 7.62% gain, while Cleanspark (NASDAQ: CLSK) rose 25.88%. The market now values miners based on their HPC contract backlog, delivery timelines, and counterparty credibility rather than hash rate. Firms like Terawulf, Hut 8, and Core Scientific are being re-rated as data center operators, decoupling from Bitcoin’s price. In the coming quarters, AI infrastructure will likely determine which miners thrive, making BTC’s trajectory a secondary factor.
