    Hyperscaler AI Capex Reaches $600B; Alphabet Backlog Hits $514B

    Question

    Hyperscaler AI Capex Reaches $600B; Alphabet Backlog Hits $514B

    Direct answer

    The scale of AI infrastructure spending is unprecedented, with three firms alone approaching $600 billion in capex. Alphabet's $514 billion backlog provides a critical fundamental offset to concerns regarding the 'payback period' of these investments. Microsoft's Azure performance ($100B annual run rate) suggests that cloud-based AI services are scaling rapidly, sustaining the demand for high-end compute and specialized memory.
