Cerebras Systems is preparing to raise up to US$4 billion in an initial public offering, targeting a valuation of about US$40 billion, in what could become one of the largest AI chip listings to date.

Samsung Electronics and SK Hynix are both riding a historic memory upcycle, but a profit gap of about KRW15 trillion (approx. US$10 billion) has opened between the two Korean chipmakers, driven largely by commodity DRAM rather than high-bandwidth memory (HBM), according to Sedaily.
