Tesla reported a significant 61% drop in profit for the fourth quarter, signaling challenges in maintaining its position as the leading electric vehicle manufacturer. The company announced plans to invest $2 billion in Elon Musk's artificial intelligence startup, xAI, despite mixed reactions from shareholders. In a prior vote, shareholders had rejected a proposal for this investment, indicating some reluctance about Musk's AI ambitions. In a shift in product strategy, Tesla will end production of its high-end Model S and Model X vehicles due to sluggish sales. Instead, the company plans to repurpose the manufacturing space in Fremont, California, for its new Optimus robots. This move reflects a broader pivot as Tesla seeks to diversify its offerings beyond electric vehicles and into robotics, aligning with Musk's long-term vision for AI integration.
