AI Infrastructure Trade Fractures as Investors Reprice GPU Longevity

A visible bifurcation has opened inside the AI infrastructure complex. Nebius' surge toward $255 and CoreWeave's continued spike demonstrate that capital remains aggressively willing to fund compute capacity at premium multiples, while at the other end of the spectrum AMD is being re-rated on improving valuation but persistent industry risk, and Super Micro's strong quarter and outlook still carries an overhang of margin and disclosure concerns. The more consequential debate is analytical rather than directional: Wall Street has largely capitalized Nvidia accelerators as multi-year cash-flow engines, and commentary this session — including Jim Cramer's framing of GPUs as 'more like fine jewelry' than depreciating vehicles — has forced the depreciation schedule question into the open. If useful-life assumptions compress, the return-on-invested-capital math across every leveraged compute buildout tightens simultaneously. That risk is driving rotation toward what MarketWatch labels 'HALO' exposures — hard assets with low obsolescence, including power, cooling, electrical infrastructure and engineering services. Legence's 111% revenue surge with record backlog, despite an EPS miss and margin pressure, is the archetype: demand is unambiguous, but the market is now demanding evidence that revenue growth converts to durable returns. Meanwhile AppLovin's slide to a 52-week low shows that the AI-adjacent software cohort no longer receives automatic credit. Positioning is shifting from thematic beta toward asset-quality discrimination.
