AWS says it added more data center capacity
AWS announced it added more data center capacity than any other company in 2025, including 12 gigawatts in the fourth quarter alone, highlighting its continued dominance in cloud infrastructure expansion.
Background
- AWS (Amazon Web Services) is the world's largest cloud computing provider, renting out computing power and storage to companies and governments.
- A gigawatt (GW) of data center capacity is an enormous amount — enough to power roughly 750,000 average homes (and datacenters draw power 24/7). The 12 GW added in Q4 2025 alone is roughly equivalent to building 12 large nuclear reactors' worth of power-hungry computing infrastructure in just three months.
- This expansion reflects an infrastructure arms race among cloud giants (AWS, Microsoft Azure, Google Cloud) driven by the insatiable power and compute demands of AI workloads like training large language models.
- AWS's claim to have added "more capacity than any other company" in 2025 signals its determination to maintain leadership against Microsoft (which has made large deals like reviving Three Mile Island to power its datacenters) and Google in the AI era.
