TAIPEI (Reuters) -TSMC, the world’s largest manufacturer of advanced artificial intelligence chips, is set to post a 28% jump in third-quarter profit to reach a record high due to surging demand for AI infrastructure, though U.S. tariffs may complicate its outlook. Taiwan Semiconductor Manufacturing Co, the world’s biggest contract chipmaker and a key supplier to Nvidia and Apple, is likely to report a net profit of T$415.4 billion ($13.59 billion) for the three months through September 30, showed an LSEG SmartEstimate compiled from 20 analysts. TSMC has already flagged a market-forecast-beating rise in third-quarter revenue of 30%.
