Wall Street anticipated a muted open Tuesday after the S&P 500 and Nasdaq saw gains for two consecutive sessions, driven by tech stocks, particularly Nvidia, which hit a record close. At CES, CEO Jensen Huang showcased new AI applications, including a real-world foundation model called Cosmos and an AI-driven video game chip, potentially igniting the AI PC movement. He also highlighted Nvidia's partnership with Toyota for self-driving technology, boosting shares of both companies, while Aurora Innovation surged over 35% following its collaboration with Nvidia.
