Elon Musk has poured more cold water on speculation that he will fold his two biggest brands together, telling an X user in the early hours of Monday that he does “No” – with a single-word reply – to the idea of merging his year-old artificial-intelligence venture xAI with electric-car maker Tesla. The brisk dismissal followed a weekend flurry of headlines suggesting closer ties were inevitable after Musk floated the possibility of letting Tesla shareholders vote on taking a minority stake in the AI outfit. In the same thread he conceded that such an investment would be “great” but stressed it would have to clear both board and shareholder hurdles at the automaker.
That tension comes as cash from the rest of the Musk empire is already flowing freely into the start-up: the Wall Street Journal first reported, and Fox Business later confirmed, that SpaceX has committed about $2 billion to xAI as the anchor of a planned $5 billion equity round. The infusion could value xAI north of $120 billion – and bankers involved in the talks have bandied numbers as high as $200 billion – handing the fledgling firm one of the richest war-chests in the generative-AI race.
Keeping the companies separate, at least on paper, does not mean their products will stay siloed. Last week Tesla started pushing a software update that drops Grok, xAI’s flagship chatbot, straight into the dashboards of AMD-powered vehicles, giving drivers a voice assistant Musk claims is “the smartest AI in the world.” The move mirrors earlier integrations of Grok into X customer support and Starlink help pages and underscores how Musk can weave together his portfolio without resorting to formal M&A.
Analysts are split on whether that loose federation is enough. Bulls argue that Tesla already commands industry-leading talent in autonomy and custom silicon and gains more strategic flexibility by buying services from xAI rather than absorbing its soaring compute bills. Sceptics counter that rivals ranging from OpenAI’s partnership with Microsoft to Google’s all-in-one Gemini push show the benefits of tight vertical control; they fear Tesla could still wind up paying near-retail prices for cutting-edge models its shareholders effectively underwrite. For now, though, Musk appears content to let xAI chase ever-larger language models and funding rounds while Tesla focuses on shipping its long-promised fully self-driving “CyberCab” next year – an arrangement he has just made abundantly clear he has no intention of changing any time soon.
