Uber's stock rose approximately 5% in early trading on Tuesday after the company expanded its autonomous driving partnership with NVIDIA to deploy self-driving taxis. The ride-hailing firm announced plans to use NVIDIA's software to launch an AI-powered autonomous fleet, with initial deployments expected in major cities followed by a broader global rollout. This move is part of Uber's strategy to scale autonomous mobility without building its own technology stack. The collaboration builds on NVIDIA's DRIVE platform, which provides the computing and software required for Level 4 autonomous driving, meaning vehicles can operate without human intervention under specific conditions. Both companies anticipate starting with supervised systems before progressing to fully autonomous operations. Uber has been leveraging the autonomous driving partner market, collaborating with various technology and automotive companies as competition in the robotaxi sector intensifies. The company increasingly positions itself as a platform connecting passengers with multiple autonomous operators rather than owning its own fleet. Analysts suggest that this broader ecosystem approach may help Uber scale faster, though the timeline for full autonomy will likely depend on regulatory approvals and infrastructure readiness in each market.
