Hitachi Shares Soar on Partnership With OpenAI
By Ronnie Harui
Shares of Hitachi surged after the Japanese electronics and industrial giant formed a partnership with OpenAI, one of several commitments the AI startup made as part of Sam Altman's dealmaking trip to Asia.
Hitachi's stock climbed as much as 9.9% to 4,285 yen in Tokyo trading. The gain, if sustained, would be its largest intraday jump in nearly six months. Japan's benchmark Nikkei Stock Average was recently 1.5% higher on Friday.
The advance came a day after OpenAI signed a preliminary deal with Hitachi during a meeting in Tokyo between the chief executives of both companies.
Under the agreement, the Japanese conglomerate will support OpenAI in developing AI infrastructure, including providing power transmission and distribution equipment to the U.S. startup's data centers, The Wall Street Journal reported, citing people familiar with the matter. OpenAI, meanwhile, will provide its models and other technologies to Hitachi.
Hitachi said in a post on X that the two companies signed a memorandum of understanding to collaborate on sustainable and plentiful energy to power the growth of artificial intelligence.
The agreement followed initial deals OpenAI struck with Samsung Electronics and SK Hynix earlier this week for its Stargate infrastructure project. Shares of Samsung and SK Hynix surged on Thursday.
News Corp, owner of The Wall Street Journal and Dow Jones Newswires, has a content-licensing partnership with OpenAI.
