CoreWeave (CRWV) has seen its market value drop by $33 billion over the past six weeks amid concerns about AI data center construction delays and mixed messaging from its CEO Michael Intrator, The Wall Street Journal reported Tuesday.

CoreWeave shares fell 5% in morning trading.

The company's 46% share price decline has also come as investors have grown increasingly concerned about a potential AI bubble, the report said.

The report noted that over the summer, heavy rain and wind caused a roughly 60-day delay at the Denton, Texas construction site where Core Scientific (CORZ) is building an AI data-center for CoreWeave. The delay pushed back the completion of the data-center cluster, consisting of about 260 megawatts of computing power that CoreWeave plans to lease to OpenAI, by several months, according to the report. There were additional delays caused by revisions to design plans for some of the data centers a partner is building for CoreWeave in Texas and elsewhere, the report said.

The Journal report added that CEO Intrator made mixed comments regarding the delays and their potential impact that further contributed to the stock's decline.

CoreWeave did not immediately respond to requests for comment from MT Newswires.
