According to @charliebilello, Microsoft, Amazon, Google and Meta will collectively allocate about $400 billion to capital expenditures in 2025, roughly four times 2020 levels, underscoring an unprecedented AI infrastructure build-out (source: @charliebilello, X post on Nov 7, 2025; referenced YouTube video). For trading, the $400 billion figure provides a concrete top-down benchmark for positioning in mega-cap AI beneficiaries and related themes, with the 4x 2020 multiple highlighting the acceleration in spend to monitor across earnings, guidance, and data-center supply chains (source: @charliebilello for the spending figures). Crypto market participants can track AI-related sentiment using this CapEx signal as a reference input when evaluating risk appetite in AI-adjacent narratives, while anchoring expectations to the verified $400 billion number rather than speculation (source: @charliebilello for the spending figures).
