Bitcoin hovers near $80,000. Miners face a squeeze. The 2024 halving slashed block rewards from 6.25 to 3.125 BTC per block, gutting revenues. Hashprices plunged to $29 per petahash-second in 2025's darkest days. Average production costs hit $79,995 per coin last quarter, per CoinShares data. At current prices, that's a $19,000 loss per bitcoin mined.
Public miners carry over $4 billion in liabilities. Core Scientific dumped $175 million in BTC in March alone. But a shift brews. AI hosting. High-performance computing. Four pure-play miners—Core Scientific, TeraWulf, Hut 8, Cipher Mining—have locked in more than $30 billion in contracts. Industry-wide, public firms boast over $70 billion in AI deals, according to Yahoo Finance.
Miners built the infrastructure. Vast power contracts. Cooling systems. Substations. Data centers primed for power-hungry AI workloads. AI generates up to three times the revenue per megawatt versus mining, CoinShares reports. No more boom-bust cycles tied to BTC price swings. Steady leases instead.
Leaders Seize the Power Play
Core Scientific leads. A $10.2 billion, 12-year pact with CoreWeave anchors its pivot. Mining revenue? Down to $42.2 million in Q4 2025 from $79.9 million a year prior. Colocation? Up to $31.3 million from $8.5 million. The firm plans to sell most BTC holdings in 2026 to fund expansion, as noted by The Block.
TeraWulf solidified HPC as its growth engine. Over $12.8 billion in long-term contracts. Q4 2025: $26.1 million from digital assets, $9.7 million from HPC leases. Year-end BTC stash? Just three coins after mining 1,496 and selling 1,500. Full-year 2025 revenue climbed 20.3% to $168.5 million, though losses widened amid the buildout, per The Block.
Hut 8 nailed a 15-year, 245-megawatt AI lease at River Bend, Louisiana, worth $7 billion total. Cipher inked multi-billion deals with Fluidstack, plus 600 megawatts for HPC tenants. IREN secured a $9.7 billion, 10-year Microsoft contract, fueling a $3.6 billion credit facility. CleanSpark posted $181 million Q1 revenue, grabbing up to 890 megawatts in Texas and Georgia for AI sites.
Riot Platforms doubled down. Q1 2026 brought $33.2 million in data center revenue—its first from AI hosting—via an expanded AMD deal at Rockdale, Texas. Total revenue: $167.2 million, up from $161.4 million year-over-year, Decrypt reports. Shares jumped 8% on the news. Activist Starboard Value pegs Riot's AI potential at up to $21 billion in equity value.
And Bitfarms? CEO Ben Gagnon eyes steady cash from HPC: "The contracts associated with HPC/AI customers provide long-term, steady cash flows and earnings streams, while our bitcoin mining operations will continue to monetize bitcoin’s flexible upside potential," he said, per Yahoo Finance.
Projections stun. Mining could shrink to 30% of revenue in two to three years, from 90% now. Capriole Investments' Charles Edwards warns of the shift on X, noting stocks targeting 80%+ AI revenue surged 500% on average. Cointelegraph echoes: Miners on track to earn more from AI than Bitcoin by year-end.
Debt piles up. Convertible notes and bonds hit records—up to $6 billion in Q3 2025—to finance buildouts. Core Scientific tapped $3.3 billion in junk bonds. TeraWulf raised $900 million via shares. Risks mount: dilution, interest costs, execution delays.
Q1 Scorecard Looms—and Bitcoin's Backbone Shifts
Earnings week hits May 5-8. MicroStrategy, Cipher, Hut 8, Core Scientific, Coinbase, Block, TeraWulf report. Investors watch: Does AI offset post-halving pain? Hashrate pressure eases as big players divert power. Difficulty down 6% in 90 days. Smaller miners gain—more BTC for them.
But concerns linger. Charles Edwards on X: "The energy and commitment to Bitcoin is under significant threat… the backbone of its security is leaving the industry." Public firms sell BTC treasuries—MARA $1 billion recently—to fund the flip. IREN liquidates daily mined coins, holds none.
AI demand surges. Data center bottlenecks: eight-year build times, permitting wars. Miners arbitrage with ready sites. VanEck's Matt Sigel: They're "sitting on a gold mine." Morgan Stanley's Stephen Byrd sees TeraWulf and Cipher doubling, powered by Google and Amazon pipelines.
Hybrid models emerge. Mining for upside, AI for baseload. Power arbitrage: curtail miners during peaks, run AI steady. Yet quantum threats loom, hashpower wanes. Miners evolve from BTC prospectors to compute kings. Q1 results will show if the lifeline holds.
