TeraWulf Peer Core Scientific Signs 12-Year AI Hosting Deal

What happened

Core Scientific announced a 12-year AI compute hosting contract with CoreWeave, marking one of the sector's most concrete examples of infrastructure repurposing. The deal allows Core Scientific to monetize power capacity, facilities, and cooling systems for high-performance computing workloads rather than solely Bitcoin mining. Across the sector, public miners collectively sold 32,000 BTC in Q1 2026 to fund similar transformations-exceeding total miner sales for all of 2025 and surpassing the roughly 20,000 BTC dumped during the 2022 Terra-Luna collapse. Riot Platforms alone offloaded 3,778 BTC for $289.5 million during the period, more than double the 1,473 BTC it actually mined. These sales funded data center expansions and GPU infrastructure buildouts, converting Bitcoin holdings into AI-adjacent capacity.

Why it matters

For TeraWulf and peers, the Core Scientific deal validates a critical strategic shift: mining infrastructure can generate revenue streams independent of Bitcoin price volatility and halving cycles. A 12-year contract provides the kind of revenue visibility that capital-intensive businesses need, especially when Bitcoin mining margins face pressure from the 2024 halving, rising network difficulty, and electricity costs that sometimes exceed $78,000 per coin at current prices. However, the pivot fundamentally changed how mining stocks trade. Since April 2026, Riot's shares have tracked the semiconductor SOX ETF almost move-for-move, meaning miner valuations now respond to AI sentiment, chip supply chains, and data center demand rather than Bitcoin's price action. Mining stocks fell roughly 20% in early July 2026 when AI enthusiasm cooled, even as Bitcoin held steady near $63,000. This represents an unprecedented divergence: year-to-date through early July, Bitcoin declined about 29%, yet RIOT gained around 80% and MARA rose roughly 44%.

Bigger picture

Public miners have collectively announced over $70 billion in AI and high-performance computing contracts, according to CoinShares. Companies furthest along in AI diversification-Core Scientific, Cipher Mining, IREN, and Hut 8-have captured valuation premiums, trading at higher enterprise-value-to-sales multiples than pure-play Bitcoin miners. A VanEck analysis valued these firms as AI infrastructure based on energized power capacity, with operators holding secured leases commanding multiples above 10 times gross energized power, while those still marketing pipelines traded between 2 and 6 times. The framework also highlighted a roughly $50 billion funding gap industrywide for full build-out, underscoring delivery risk and capital intensity. The transformation means investors seeking pure Bitcoin exposure might prefer holding the asset directly, while those betting on miners are now exposed to semiconductor cycles, hyperscaler budgets, and data center demand-factors once irrelevant to the mining thesis.

What to watch

Monitor whether AI hosting contracts deliver the promised margins and whether miners' aggressive Bitcoin sales-used to fund infrastructure pivots-prove justified if AI buildout slows or compute pricing compresses. Track how mining stocks respond to semiconductor earnings and AI sentiment shifts rather than Bitcoin price moves. Watch for further long-term hosting agreements among peers, which would signal deeper sector transformation. Also observe Bitcoin network difficulty adjustments and whether miners' power reallocations toward AI affect overall hashrate stability. Finally, keep an eye on whether companies like TeraWulf announce similar AI hosting deals, as those without secured contracts may trade at significant valuation discounts.
