Cerebras Systems, a leader in AI chipmaking, has postponed its IPO yet again due to ongoing national security reviews. Initially filed in September 2024, the company anticipated a smoother process with the incoming Trump administration. However, key positions in the White House remain unfilled, including the assistant Treasury secretary for investment security, which oversees such reviews. The IPO's scrutiny stems from a significant $335 million investment from Abu Dhabi's G42, which has connections to Huawei. TechCrunch is waiting for a response from Cerebras regarding these developments.
