Trump on Wednesday said he would impose roughly 100% tariffs on all chips coming into the U.S., but exempt technology companies that have promised to manufacture domestically. TSMC receiving an exemption would make sense, as it has pledged a total of $165 billion in U.S. investment, including building three new chip plants.

Samsung is boosting its US chip investments to as much as $50 billion, aiming to compete with TSMC and avoid steep tariffs on imported chips.

Officials in Taiwan and South Korea say they don't expect Trump's 100% tariff on foreign chips to affect TSMC or Samsung, likely due to their factory investments in the US.
