1Hyperscalers (Alphabet, Amazon, Microsoft, Meta) convert $145-205B each of 2026 capex into owned GPU/datacenter capacity
2Apple holds FY2025 capex to $12.7B and rents third-party compute, pairing its own chips and servers with partners' infrastructure and models (Siri AI is a ground-up rebuild running on Google's Gemini in beta)
3If AI compute demand keeps tightening capacity and hyperscalers allocate their frontier hardware and models to their own ecosystems, the price and availability of the compute Apple rents deteriorates
4That deterioration pushes Apple toward owning capacity
5If Apple pivots to ownership, its capex and R&D step up and the gap between its spending profile and its cash-rich, buyback-funded balance sheet narrows
6If it keeps renting, it preserves operating margin but stays exposed to partners' pricing and priority
