Tesla has increased its spending plan for the year to $25 billion, with Elon Musk announcing a significant boost in investments for self-driving taxis, trucks, robots, and new chip factories. Previously, Tesla's capital expenditure guidance for 2026 was $20 billion, with the new forecast nearly tripling last year's investment. After the earnings release, Tesla's stock price initially rose and then fell by 1% in after-hours trading. Musk is shifting the company's focus from consumer vehicles to AI-driven businesses. However, the scale of self-driving taxi experiments remains limited, and the launch of Optimus humanoid robot production has been delayed. Tesla achieved growth in both net profit and revenue in the first quarter, with adjusted profit rising by 56% after excluding certain expenses. Although capital expenditures surged this quarter, they still fell short of expectations. There is external speculation that Musk may merge Tesla with SpaceX, and Jefferies analysts believe that Tesla's capital expenditure plan could raise funding concerns, increasing the logic of such a merger.
