AI infrastructure build-out opportunities

What happened: AI infrastructure stocks surged in late March 2026, driven by significant developments. CoreWeave secured an $8.5 billion loan to expand its AI cloud platform, while Nebius announced plans to build a 310MW AI factory in Finland and a $10 billion data center in Europe. Applied Digital reported progress towards increased data center capacity. Meanwhile, Bitfarms announced a rebrand to Keel Infrastructure, pivoting from Bitcoin mining to AI data centers. Amazon.com maintained strong analyst support as an AI infrastructure stock.

Market impact: The AI infrastructure sector is booming, with companies like CoreWeave, Nebius, Applied Digital, and Keel Infrastructure expanding capacity to meet surging demand. This trend is expected to continue, with Statista predicting AI infrastructure spending to reach $902 billion by 2029. Nvidia and Iren are well-positioned due to their roles in GPU and data center power supply, respectively. However, the sector's growth may also attract competition, potentially impacting valuations.

What to watch next: Investors should monitor Q1 2026 earnings from AI infrastructure stocks, with Nvidia reporting on May 24. Additionally, the commencement of Nebius' AI factory operations in Finland in 2027 will be a key milestone to watch. Lastly, regulatory decisions regarding data center siting and power allocation could impact the sector's growth trajectory.
