Microsoft, Amazon, and Alphabet saw their combined market capitalization soar by nearly $1.5 trillion this past week, a move that adds the economic size of Spain to their collective value.

Alphabet now hovers around a $4.3 trillion valuation, Microsoft approaches $2.8 trillion, and Amazon sits close to $2.5 trillion. This surge highlights how aggressively investors are betting on AI infrastructure growth.

The big four hyperscalers, including Meta, plan to pour $725 billion into capital expenditures for 2026, marking a 77% rise from last year. This massive spending spree underpins the recent rally but hasn’t been without turbulence.

Earlier this year in February, these companies together shed over $1 trillion post-earnings amid fears that AI investments were outpacing revenue. Despite that, their combined market cap now exceeds the GDP of every country aside from the US and China.

Such bullish sentiment tends to lift riskier assets too, with crypto markets often moving in step with these tech giants. A sharp reversal in AI stocks could quickly send ripple effects across Bitcoin and other digital assets given their documented correlation with Nasdaq during selloffs.

Investors tracking AI-related crypto tokens should note the stark mismatch between the massive hyperscaler budgets and the nascent earnings from decentralized AI projects. Tokens currently fueled by hype may soon need solid financials to sustain valuations.
