AI-focused miners surge in 2025 as IREN leads; Bitdeer lags
Public bitcoin miners diverged sharply in 2025 as companies pivoting to AI and high-performance computing (HPC) substantially outperformed pure-play BTC miners. IREN led the sector with roughly +300% year-to-date gains driven by major GPU cloud deals and Microsoft backing. Cipher Mining rose about +230% via expanded AI hosting partnerships, and Hut 8 gained ~+139% after announcing a $7 billion, 15-year AI data-center lease (245 MW) at its River Bend site. By contrast, large BTC-holding pure miners underperformed: Marathon (53,250 BTC) fell ~44% YTD, CleanSpark (13,011 BTC) rose ~16%, Riot Platforms (19,324 BTC) rose ~32%, and Core Scientific was up ~9% after rejecting an acquisition. Bitdeer was the biggest laggard, down ~50% following a disappointing Q3, wider net loss and delays to its ASIC chip that cloud its AI expansion plans. The takeaway for traders: diversification into AI/HPC—GPU cloud deals, hyperscaler partnerships and long-term data-center contracts—drove share-price outperformance this year, while BTC holdings alone were insufficient to guarantee gains amid earnings shortfalls and execution risks.
Neutral
The news signals a sector rotation within mining equities rather than a clear directional cue for the broader crypto market. For equities: companies that secured AI/HPC deals show strong fundamentals tied to recurring revenue (leases, cloud contracts) and strategic partnerships, which is bullish for those stocks. Conversely, pure-play miners with large BTC treasuries but weak earnings or execution issues (e.g., Bitdeer, Marathon) have underperformed, a bearish signal for those tickers. For spot crypto (BTC): the article notes BTC was down ~7% YTD, but the drivers described are company-specific corporate strategy shifts rather than macro catalysts for bitcoin price — so the direct impact on BTC price is limited. Short-term implications: traders may rotate capital into AI-focused miner stocks and sell or short underperforming pure miners, increasing volatility in mining equities. Long-term implications: sustained AI demand and long-term leases could re-rate select miners to higher valuations, while continued execution failures or delayed tech (ASIC) could permanently impair laggards. Historical parallels: similar re-ratings occurred when miners diversified into hosting/cloud services during past capex cycles — those that secured recurring contracts tended to outperform. Overall market stability for crypto assets should remain largely unchanged unless AI pivots trigger substantial balance-sheet changes (asset sales, leverage) or material shifts in mining hash rate economics that feed into BTC macro dynamics.
