Tesla stock fell by approximately 3% after Nvidia CEO Jensen Huang unveiled the Alpamayo open-source AI model family at CES 2026. Investors are reassessing Tesla’s AI leadership in self-driving technology as Alpamayo targets the ‘long-tail’ edge cases that have challenged autonomy developers. While Tesla’s Full Self-Driving suite remains proprietary and deeply integrated with its vehicle fleet, analysts note that Nvidia’s platform could be adopted by multiple automakers, potentially narrowing Tesla’s competitive edge. Market participants will be watching Tesla’s upcoming Q4 earnings release on February 12 for any commentary on its AI roadmap and partnerships.

Tesla’s Shanghai Gigafactory achieved a record month in December with 97,171 vehicle deliveries, marking its strongest performance since production began. Despite this year-end surge, full-year shipments from the China plant declined compared to 2024, as sustained price competition from local electric vehicle makers and regulatory incentives faded. Total China deliveries for 2025 fell by an estimated 5%, according to industry group data, raising questions about Tesla’s ability to maintain growth in its largest overseas market. Investors will be monitoring Tesla’s pricing strategy and inventory levels in the coming quarters.

In the UK, Tesla car registrations tumbled by more than 29% in December year-on-year, according to the Society of Motor Manufacturers and Traders. The decline underscores growing pressure from established brands and new entrants offering lower-priced electric models. Tesla’s market share in the UK EV segment slipped by nearly four percentage points over the last quarter. Company executives have signaled plans to adjust incentives and roll out localized software updates to bolster demand, but investors remain cautious about short-term volume trends in Europe.

Tesla announced fourth-quarter deliveries of 418,227 vehicles, down 16% from Q4 2024, extending a two-year slide in annual deliveries. While production efficiencies and cost reductions have improved margins, the company still faces pressure to reignite volume growth. Management reaffirmed its target of 1.8 million vehicle deliveries in 2026, relying on the ramp-up of the Cybertruck and expected enhancements to its Shanghai and Texas factories. For growth investors, the key question is whether Tesla’s next generation of vehicles and unfolding software monetization efforts can offset intensifying competition and plateauing demand in core markets.
