Shares of Blackstone's newly minted investment vehicle opened flat in their market debut on Thursday, after the company raised $1.75 billion in its U.S. initial public offering with plans to buy data center assets. New York-based Blackstone Digital Infrastructure Trust's stock opened at $20 per share, the same price at which it had sold 87.5 million shares in its IPO. Artificial intelligence-linked companies have taken center stage in the U.S. IPO market this week with three billion-dollar offerings, including chipmaker Cerebras and Fervo Energy.
