Meta vs Alphabet: Billion-Dollar Bet on AI Infrastructure

The comparison between Meta (META) and Alphabet (GOOGL), two of the largest players in advertising and AI infrastructure, continues to generate attention. TradingKey's report, 'Meta vs. Google: Which Is the Better Long-Term Investment?', highlights their Q2 2026 earnings, capital spending, and market valuations.

As of September 25, 2026, Meta shares sit at $751.66, carrying a $1.91 trillion market cap, while Alphabet closed at $343.92 with a market cap of $4.21 trillion. The gap between their market caps is over $2.3 trillion.

Meta's Q2 2026 earnings showed revenue of $60.8 billion, up 28% year-over-year, driven by a 14% rise in ad impressions and a 12% increase in the average price per ad. Alphabet's Q2 2026 earnings were larger in absolute dollars, with total revenue reaching $119.8 billion, up 24% year-over-year.

Both companies are spending heavily on AI infrastructure, with Meta's capex at $31.08 billion and Alphabet's at $44.9 billion in Q2 2026. Their full-year 2026 capex outlooks are also significant: Meta expects $130 billion to $145 billion, while Alphabet aims for $195 billion to $205 billion.

The difference in scale is clear, but so is the potential payoff. Alphabet's Google Cloud revenue grew 82% year-over-year, with an operating margin of 35.6%. Meta's Reality Labs division remains a drag on margins, despite the ad side accelerating.
