The four tech giants, Microsoft, Alphabet, Meta, and Amazon, have reaffirmed their plans to spend billions on AI infrastructure, with a combined market capitalization of approximately $12 trillion. According to a Bridgewater Associates analysis, these companies are expected to spend around $650 billion on AI infrastructure in 2026. Although most of them did not provide a detailed breakdown of their AI spending in their latest earnings reports, they appear to be on track to meet their targets. This investment has significant implications for the digital asset sector, particularly for bitcoin miners who are diversifying their revenue streams by hosting AI computers.
The miners already have the necessary data centers and are leveraging them to support AI computing. Stocks with exposure to AI-linked bitcoin mining and hyperscaler infrastructure deals include IREN, TeraWulf, and Cipher Digital.
The earnings reports from these tech giants have also led to fluctuations in their stock prices, with Microsoft down 2.4%, Alphabet up 6%, Meta down 6.6%, and Amazon down 3.7% in after-hours trading. The next major test of market sentiment will be when chipmaker Nvidia reports its earnings on May 20. The tech giants' earnings reports and statements from their CEOs highlight the importance of AI in driving their growth and investments. Microsoft reported fiscal Q3 2026 revenue of $82.9 billion, with its AI business generating $37 billion, up 123% year-over-year.
Alphabet reported Q1 2026 revenue of $109.9 billion, with Google Cloud revenue rising 63% to $20 billion, driven by AI-driven demand. Amazon reported Q1 2026 revenue of $181.5 billion, with a significant increase in infrastructure spending, primarily driven by AI investments. Meta reported Q1 2026 revenue of $56.31 billion, with rising AI infrastructure costs driving its spending, and CEO Mark Zuckerberg framing the push as a 'milestone quarter' tied to AI progress.
