    GPT-5.4 generated $1B in net-new ARR within a single week — the fastest revenue ramp in AI history — while Big Tech quietly accumulated $700B+ in off-balance-sheet infrastructure commitments and Meta's margins compress from 48% to 35%.

    GPT-5.4 proved AI monetizes ($1B ARR in one week), but $700B in hidden off-balance-sheet infrastructure commitments — led by Oracle's $260B and Meta's $131B commitment quadrupling — creates stranded-a…
