Nvidia CEO Jensen Huang is expected to attend a Tuesday White House meeting with President Donald Trump, House Speaker Mike Johnson and other artificial-intelligence executives. Dubbed the “Golden Age” gathering, the event will focus on AI policy and marks Huang’s second White House appearance in less than a week. Nvidia has pledged $500 billion in investments tied to favorable U.S. policies on AI and semiconductor exports. The company’s advanced chips power much of the latest AI training, while export controls (government limits on technology sales) have restricted which products Nvidia can sell to Chinese buyers. Huang has argued that overly aggressive controls could encourage Chinese companies to develop competing technology and weaken America’s lead. Nvidia has been designing modified chips to comply with existing rules while retaining access to China, making policy changes important for potential revenue. High-level policy events can also cause short-term volatility in semiconductor stocks even without an announced rule change.
