IREN, Nebius, Nvidia and Coherent are backed by signed contracts in a $602 billion hyperscaler capex cycle, 75% of it for AI, already committed through contracts, bonds and supply deals. Nvidia's $2 billion stakes in Coherent, Nebius and Marvell lock in its supply chain for a decade. Nebius has $46 billion of commitments from Meta and Microsoft, and IREN targets 140,000 GPUs and 85% EBITDA margins by end-2026. Valuation is the risk, with some sales multiples near 2000-bubble levels. x.comÂ
