The statement is substantively true. Multiple credible sources (Reuters, Yahoo Finance) explicitly report that an investment consortium, which includes both BlackRock and Nvidia, will acquire Aligned Data Centers in a deal valued at $40 billion. While the statement simplifies the matter by not mentioning other consortium members like xAI and Microsoft, the core claim that BlackRock and Nvidia are involved in a $40 billion data center acquisition is directly supported and corroborated by the evidence.
