The two South Korean chipmakers signed letters of intent on Wednesday with OpenAI Chief Executive Sam Altman to supply high-bandwidth memory (HBM) semiconductors for the US start-up’s so-called Stargate initiative, a program to construct a network of hyperscale AI data centers around the world by 2029.
The San Francisco-based company, the creator of generative AI ChatGPT, has requested volumes equivalent to as many as 900,000 wafers a month,
more than twice the current global production capacity.
Analysts estimate the commitment amounts to more than 100 trillion won ($72 billion) of incremental demand for the Korean chipmakers over the next four years.
