Oracle Corp. is facing a proposed class-action lawsuit from bondholders who claim they suffered financial losses after the company allegedly failed to disclose its plans to issue substantial additional debt to fund its artificial intelligence infrastructure.

The suit, filed Wednesday in a New York state court in Manhattan, was brought on behalf of investors who purchased $18 billion of notes and bonds issued by Oracle in September. The lawsuit names Oracle CEO Larry Ellison, as well as the banks involved in the debt offering, as defendants.

According to the complaint, plaintiffs allege that Oracle’s nondisclosure prevented them from fully understanding the company’s financial strategy and exposure, potentially impacting the value of their investments. The case underscores growing scrutiny over corporate transparency in tech companies investing heavily in AI and other high-cost initiatives.

No comment has yet been issued by Oracle or its executives regarding the lawsuit.
