AWS Loses Ground to Google Cloud as Market Share Gap Widens

AWS still dominates the cloud infrastructure market, but Google Cloud is gaining ground. Synergy Research Group's Q2 2026 tracking shows AWS at 28% of global cloud infrastructure spending, down from 30% a year earlier. Google Cloud climbed to 15%, its highest share on record and up from about 13% in the same period last year.

AWS generates more absolute revenue than Google Cloud by a wide margin: $42.2 billion in revenue with 37% year-over-year growth, while Google Cloud's growth rate hit 82%. This growth differential matters for buyers because it signals where the two companies are investing.

Google Cloud is growing off a smaller base but is converting that growth into faster iteration on newer categories, particularly AI infrastructure, ARM compute, and BigQuery-adjacent analytics tooling. Neither trend is new, but the size of the growth gap in 2026 is the widest it has been since Google Cloud became a reportable Alphabet segment.

AWS still runs the biggest cloud on the planet by a wide margin, but Google Cloud posted 82% year-over-year revenue growth in its most recent quarter against AWS's 37%. The market share gap between the two companies is now 13 percentage points, according to Synergy Research Group's Q2 2026 tracking.
