Shares in China’s Contemporary Amperex Technology (CATL), the world’s largest electric vehicle battery maker, have surged as much as 18% on its first day of trading in Hong Kong, shrugging off geopolitical uncertainties.

Contemporary Amperex Technology Co., the world’s largest maker of electric batteries, saw its shares rise as much as 18% on Tuesday after raising $4.6 billion in the top initial public offering of the year — and it mostly excluded Americans from participating.

CATL is foraying into global markets amid growing trade tensions between the U.S. and China, which have sent markets careening over the past several weeks.

Shares of Contemporary Amperex Technology Co., or CATL, soared more than 16% in their Hong Kong trading debut Tuesday after the Chinese electric vehicle battery maker raised more than $4.5 billion in the world's largest listing this year.

With total assets of $53.7 billion, FWD Group has launched its fourth IPO attempt in Hong Kong, tapping into surging investor interest following battery giant CATL’s landmark listing.

China’s CATL supplies about one in three electric cars, with Tesla, Ford, Volkswagen, and others among its clients.

The company secured offtake agreements from Europe and the United States but did not specify which firms were looking to procure the EV batteries produced through theproject.

The world’s biggest IPO this year excludes U.S. onshore investors. The decision reduces geopolitical risks that loom over Chinese battery maker Contemporary Amperex Technology's $4 billion Hong Kong debut.
