Recent earnings reports suggest that Google Cloud is outpacing Amazon and Microsoft in the AI build-out. Alphabet's Google Cloud revenue surged by 63% year over year, surpassing Microsoft Azure's 40% and Amazon AWS's 28% growth. This marks Google Cloud's third consecutive quarter of accelerated growth, with a cloud backlog that nearly doubled in three months, suggesting this lead could widen. Although Google Cloud's $20 billion in revenue still trails AWS and Microsoft's broader cloud segments in terms of size, its growth rate is a key indicator of its potential in this new era. Microsoft's Azure has maintained a consistent growth rate, while AWS has accelerated, but still lags behind Google Cloud. Alphabet has also seen exceptional momentum in its cloud segment's profitability, with operating income climbing significantly and operating margin expanding. Alphabet CEO Sundar Pichai highlighted the company's strong performance during the recent earnings call.
