# Microsoft, Amazon, and Google add $1.5T in market cap in a single week > Source: > Published: 2026-07-31 20:14:38+00:00 Via news.microsoft.com # Microsoft, Amazon, and Google add $1.5T in market cap in a single week The three tech giants collectively gained nearly $1.5 trillion in valuation, underscoring just how much capital is chasing the AI infrastructure trade. Three companies added the GDP of Spain to their valuations in five trading days. Microsoft, Amazon, and Alphabet (Google’s parent company) collectively tacked on nearly $1.5 trillion in market capitalization this week. The surge puts Alphabet at roughly $4.3 trillion in market cap, with Microsoft sitting around $2.8 trillion and Amazon near $2.5 trillion. ## The AI spending machine behind the rally The four largest hyperscalers, which include Meta alongside this week’s three big winners, have guided for a combined $725 billion in capital expenditures for 2026. That’s a 77% increase compared to the prior year. ## A volatile road to get here Back in February 2026, Alphabet, Microsoft, Amazon, and Meta collectively lost over $1 trillion in market cap following their earnings releases. That earlier selloff was driven by concerns that AI spending was getting ahead of actual revenue generation. The combined market cap of these three companies, roughly $9.6 trillion, exceeds the GDP of every country on Earth except the US and China. ## What this means for crypto and digital asset investors When risk appetite is strong enough to add $1.5 trillion to three stocks in a week, that same appetite tends to spill over into other risk assets, including Bitcoin and the broader crypto market. If the AI trade reverses sharply, as it briefly did in February, the resulting risk-off environment would likely drag crypto down with it. Bitcoin’s correlation with Nasdaq during major selloffs has been well documented. For investors in AI-adjacent crypto tokens, the gap between hyperscaler capex and decentralized AI network revenue remains enormous, and tokens trading on narrative alone will eventually need fundamentals to match. **Disclosure:** This article was edited by Editorial Team.
