Altman’s fundraising plans are aimed at solving constraints to OpenAI’s growth, including the scarcity of artificial intelligence (AI) chips required to train large language models behind systems such as ChatGPT, the WSJ reported.
The Semiconductor Industry Association (SIA) has forecast a 13.1% jump in global chip sales to $595.3 billion this year, compared with a drop of about 8% in sales in 2023.
The amounts Altman has discussed are outlandishly large by the standards of corporate fundraising, the report added.
Investors have valued OpenAI at more than $80 billion.
As part of the talks, Altman is pitching a partnership between OpenAI, investors, chip makers and power providers, which together would put up money to build chip foundries that would then be run by chip makers, the report said, adding that much of the effort could be funded by debt and the discussions are in its early stages.
