Nvidia Corp.’s supply of H20 artificial-intelligence chips is unlikely to satisfy rapidly growing demand from Chinese customers, according to a note from Jefferies that warned the current stockpile is insufficient. Trading updates on 29 July show the chipmaker has responded by ordering roughly 300,000 additional H20 units from contract manufacturer Taiwan Semiconductor Manufacturing Co., helping lift Nvidia’s shares about 1.5% in U.S. pre-market dealings. Separately, White House senior adviser Kevin Hassett said the administration wants China to continue purchasing U.S. chips such as the Nvidia H20 and cautioned that Washington does not want Beijing to set the global standard for AI semiconductors.
