Bitcoin Miners vs Hyperscalers: The 4 Stocks Solving AI's $600B Photonics Crisis

April 17. We posted a thread. Three names from it have moved since — $POET +114%, $AEHR +36%, $IREN +29%. Pre-permitted Bitcoin mining sites can host AI in 6–9 months. Hyperscaler greenfield builds take 2–3 years. Four public names sit on top of that timeline gap most of Wall Street is still missing. This is not a hyperscaler-capex story. It's not an Nvidia story. It's a 12-minute walk through the AI photonics supply chain — three chokepoints decided upstream, and the four operators publicly reporting they've solved them. The three chokepoints: The Materials — Indium Phosphide. Every AI-data-center laser starts as an InP wafer. Reported supply deficit already over 70%. Indium and phosphorus reportedly stuck in 18-month allocation queues. China's gallium export suspension expires November 27, 2026. The Power — Harmonic distortion. AI GPU clusters reportedly generate 3–5x more harmonic distortion than Bitcoin ASICs. Existing miner substations need active filters and STATCOMs to clear NERC compliance before a single GPU goes live. The Foundry — Photonic PDK access. TSMC and GlobalFoundries reportedly hoarding advanced photonic PDK slots for ecosystem partners. 12–18 month waitlists for everyone else. The four public names: $CORZ (Core Scientific). Per its 8-K, retrofits on 300 MW blocks plus hyperscaler-backed InP supply plus TSMC PDK access via partners. CoreWeave deal reported at $10.2B over 12 years. Reportedly declined a $9B buyout in early 2026. $IREN (IREN Ltd). Per its Q1 2026 update, the only miner with secured non-China indium allocation. 200 MW AI block targeting Q3 2026 with full photonics integration. $ETN (Eaton Corp). The active-harmonic-filter and STATCOM layer hyperscalers are reportedly funding directly via hosting deals — paid whether the miner pivot delivers or not. $AXTI (AXT Inc). The InP wafer substrate maker every laser supplier (Lumentum, Coherent) depends on — the same suppliers NVIDIA reportedly committed $4B to in March 2026. Per Q3 2025, InP revenue grew roughly 250% sequentially.
