Elon Musk is pushing for deep integration among his companies Tesla, SpaceX, and xAI. Tesla has already invested approximately $2 billion in xAI, while SpaceX plans to acquire xAI for $250 billion, aiming to break down barriers between space technology, artificial intelligence, new energy, and robotics. Tesla recently halted production of the Model S and Model X to shift focus toward manufacturing its Optimus humanoid robot, underscoring its commitment to transforming into a "physical AI company." Deutsche Bank forecasts that Tesla’s capital expenditures will exceed $20 billion by 2026, with major investments directed toward AI chips, autonomous driving, and mass production of robots. Musk stated that if the integration succeeds, Tesla could reach a market valuation of $100 trillion, though it must overcome significant challenges including regulatory hurdles, technological obstacles, and massive capital requirements. Tesla’s current market cap stands at approximately $1.54 trillion, leaving a 65-fold growth gap to reach Musk’s ambitious target.
