AI Hosting Deals Fail to Spark Stock Surges as Market Sentiment Cools

Woofun AI reports that the strategic pivot of Bitcoin miners into artificial intelligence and high-performance computing (HPC) has triggered a discernible shift in investor sentiment, moving from euphoric reception to cautious scrutiny. This transition affects key industry players including Core Scientific, CoreWeave, Applied Digital, TeraWulf, Fluidstack, Anthropic, CleanSpark, Bitdeer, and Tydal, while broader market indicators such as TheEnergyMag’s TEM AI Infrastructure Growth Index and the Philadelphia Semiconductor Index reflect the cooling enthusiasm.

Historical market reactions to early AI hosting deals demonstrated significant volatility driven by headline announcements. Core Scientific’s initial hosting agreement with CoreWeave propelled its shares up more than 40%, while Applied Digital’s first CoreWeave lease gained nearly 49%. Similarly, TeraWulf’s first Fluidstack deal surged almost 60%, illustrating how early-stage contracts were rewarded with substantial equity premiums regardless of immediate profitability metrics.

Woofun AI data shows that, in contrast, recent mega-deals have elicited markedly muted responses, signaling a maturation in valuation criteria. TeraWulf’s 401-megawatt lease with Anthropic lifted its shares by about 5%, while CleanSpark’s $6.6 billion AI hosting agreement gained nearly 9%. Bitdeer’s new Tydal contract briefly pushed the stock up roughly 12% before those gains evaporated by market close, even as annualized revenue per contracted megawatt continues to edge higher, indicating that investors now prioritize execution and financing over raw contract size.

Broader market indices further underscore this retreat from speculative fervor. TheEnergyMag’s TEM AI Infrastructure Growth Index, which tracks publicly traded companies developing AI data center and digital infrastructure businesses, is down roughly 28.5% from its June peak. This decline mirrors a broader pullback in the sector, with the Philadelphia Semiconductor Index falling nearly 17% from its July peak, suggesting that sustained infrastructure demand no longer guarantees equity appreciation.
