Klement: The Impossible Maths of the AI Boom
Klement's FT op-ed makes the cleanest bear case to date: hyperscaler capex grows 20 percent annually through 2030 against 15 percent revenue growth, and under a zero-cost assumption the implied ROI is highly negative for every hyperscaler except Amazon. Clearing a 10 percent return requires 2 to 5 trillion in additional annual revenue against a current 1.5 trillion base. The methodology is opaque and the Amazon exception goes unexplained, but the piece's real signal is positional: when the bear case migrates from Substack to FT op-ed pages, with Chancellor, Constan, WSJ Heard on the Street, and Munster all aligned within five weeks, the consensus has moved. The contrarian trade is now bull on capex sustainability, contingent on smooth IPO absorption and one quarter of hyperscaler AI revenue acceleration outpacing capex growth.
