Nebius vs. Digital Realty: Which AI Infrastructure Stock is the Better Buy?

Nebius vs. Digital Realty centers on how both companies are positioning to capitalize on accelerating AI infrastructure demand. Nebius Group N.V. (NBIS) is expanding its AI-native cloud platform by increasing contracted power capacity from above 2 gigawatts in the last three months to over 3.5 gigawatts, and it expects to exceed 4 gigawatts by year-end. It also announced a Pennsylvania data center site targeting 1.2 gigawatts at full build-out, with more than 75% of contracted power owned. Digital Realty Trust, Inc. (DLR) is instead scaling through record leasing activity, hyperscale developments, and expanded connectivity.
