Amazon, Alphabet, Microsoft Valuations Reveal Clear Weak Link in AI Spending Race

Amazon (NASDAQ:AMZN), Alphabet (NASDAQ:GOOGL), and Microsoft (NASDAQ:MSFT) are leading the artificial intelligence (AI) infrastructure spending race, with a combined total of over $590 billion planned for 2026 alone.

The three hyperscalers have taken on tens of billions in new debt to finance their AI build-outs, with Amazon set to spend around $220 billion, Alphabet guiding $195-205 billion, and Microsoft tracking towards approximately $175 billion.

While investors often group these companies together, their valuations range from 17 times earnings (Alphabet) to 28 times earnings (Microsoft), making it essential to evaluate each company's financial situation before treating them as interchangeable.

Microsoft trades at a premium of around 28x trailing earnings, which has compressed over the past year despite revenue growth of 18% and operating income climbing 31%. In contrast, Alphabet carries a P/E ratio of approximately 17 with positive free cash flow intact.
