- Blocksbridge Consulting analysis of 25 AI and HPC deals from June 2024 to August 2026 found average announcement-day stock pops fell from roughly 24% to about 10%, with median gains roughly halving over the same period
- Early AI hosting deals drew outsized investor rewards: Core Scientific's CoreWeave agreement sent shares up more than 40%, Applied Digital's CoreWeave lease gained nearly 49%, and TeraWulf's first Fluidstack deal surged almost 60%
- Recent mega-deals drew muted responses: TeraWulf's 401-megawatt lease with Anthropic lifted shares only ~5%, CleanSpark's $6.6 billion AI hosting agreement gained ~9%, and Bitdeer's Tydal contract spiked ~12% before fading by market close
- Annualized revenue per contracted megawatt has edged higher over time, meaning AI hosting agreements are becoming more lucrative per unit of capacity even as they move markets less
- The TEM AI Infrastructure Growth Index is down roughly 28.5% from its June peak, and the Philadelphia Semiconductor Index has fallen nearly 17% from its July high, reflecting a broader pullback in AI infrastructure stocks
Why it matters: Bitcoin miners pivoting to AI face a higher bar: investors are no longer rewarding the announcement, only the execution. With deal sizes growing (TeraWulf's 401 MW with Anthropic, CleanSpark's $6.6B) but stock pops shrinking to single digits, the sector's path to re-rating now depends on delivering revenue, not signing headlines.
