Today's Focus
Topics
AI Supply Chain Daily Focus — 31 July
Microsoft's 43% cloud growth and Amazon's 37% AWS acceleration reset the AI-capex debate in one session — chips ripped higher (Lam +20%, AMD/Intel +13%, CRWV +24%) and the market rewarded rather than punished record capex. The offsetting story: Apple named memory pricing a "hundred year flood" and guided September below consensus on supply constraints.
The Fed Holds: A Hawkish Pause That Outsources Tightening to the Market
The July FOMC held the range at 3.50%–3.75% as expected, but three dissents wanted 25bp now. The bigger shift is a quieter forward-guidance stance that lets market rates do the tightening — at the cost of policy clarity.
The AI Capex Supercycle: Where the Money Is Actually Going
Hyperscaler capex guidance keeps beating estimates, but the mix has shifted hard toward power, land and interconnect. A look at which parts of the chain are absorbing the incremental dollar.
The Memory Supercycle: How HBM Reallocation Is Squeezing Conventional DRAM
HBM's share of DRAM wafer output has roughly doubled in eighteen months. That reallocation, not new demand alone, is what's driving conventional DRAM pricing power.
Neocloud IPO Watch: Reading Through the Unit Economics
A wave of GPU-rental neoclouds is heading toward public markets. The pitch is straightforward; the unit economics — utilisation, depreciation schedules, contract duration — are where the real debate is.
