Korean stocks set a fresh record high Wednesday on hopes for the Seoul-Washington summit and a potential supply deal with Nvidia. The local currency was trading higher against the U.S. dollar.

Foreigners sold a net 227.3 billion won worth of local shares, and individuals offloaded a net 4361.8 billion won. Institutions bought a net 641.1 billion won.

Investors scooped up tech shares amid reports Samsung Electronics and SK Group may forge deeper ties with Nvidia in the AI sector.

Nvidia CEO Jensen Huang, who will attend the Asia-Pacific Economic Cooperation APEC CEO Summit this week, is widely anticipated to meet business leaders during his stay.

"The market focused on reports that Nvidia may sign an AI chip supply deal with Samsung Electronics, SK Group and Hyundai Motor Group," said Seo Sang-young, an analyst at Mirae Asset & Securities.

President Lee Jae Myung also met U.S. President Donald Trump on Wednesday in the southeastern city of Gyeongju, North Gyeongsang, with the tariff issue as one of the major agenda items.

Detailed outcomes from the summit were not immediately known.
