New Q3 data from Synergy Research Group shows that the number of large data centers operated by hyperscale providers has climbed to 1,297 worldwide, nearly tripling since early 2018. Over the same period, total operational capacity has increased more than fourfold as average data center size continues to rise. While strong growth has long characterized the hyperscale market, it is particularly notable that since the launch of ChatGPT in late 2022, some of the key metrics have skyrocketed, driven by aggressive AI initiatives. Over the last three years, quarterly hyperscale operator capex has ballooned, growing by almost 180% and reaching $142 billion in Q3 of this year. This has enabled a comparable 170% increase in the amount of operational capacity added each quarter. AI-driven expansion has also seen the US share of worldwide hyperscale operational capacity increase. The US now accounts for 55% of worldwide hyperscale operational capacity, up from 52% three years ago, reinforcing its position as the dominant hub for large-scale data center infrastructure. The research is based on an analysis of the data center footprint of 21 of the world’s major cloud and internet service firms, including the largest operators in SaaS, IaaS, PaaS, search, social media, e-commerce and gaming. The companies with the broadest data center footprint are the leading cloud providers – Amazon, Microsoft, and Google. In addition to a huge data center footprint in their home US market, each also has multiple data centers in many other countries around the world. In aggregate, the three now account for 58% of all hyperscale data center capacity. They are followed in the ranking by Meta, Alibaba, Tencent, Oracle, Apple, ByteDance and then other relatively smaller hyperscale operators. Synergy’s forecast growth numbers are based in large part on its tracking of hyperscale operators’ pipeline of future data centers. Synergy’s known pipeline of future hyperscale data centers currently stands at 770 facilities which are at various stages of being planned, constructed or fitted out.

 

“In Q3 nearly all key hyperscale year-on-year growth metrics increased,” said John Dinsdale, a Chief Analyst at Synergy Research Group. “Growth rates rose for data center openings, megawatts of operational capacity, data center-related capex, company revenues, and cloud-specific revenues. We have also seen a substantial expansion in the known future pipeline. Based on this analysis, Synergy has revised its five-year outlook upward for several core metrics. The firm now expects total hyperscale data center capacity to double in just over twelve quarters, underscoring the scale and speed at which AI-driven infrastructure investment is reshaping global cloud-related markets."
