Tesla shares jumped about 5% on Friday after reports suggested that Elon Musk is considering bringing his companies closer together through a possible merger involving SpaceX, Tesla, and artificial intelligence startup xAI. The news helped reverse losses from the previous session, when the stock slid following the company’s earnings report.

According to people familiar with the discussions, SpaceX has been evaluating different ways to combine parts of Musk’s business portfolio ahead of a potential public offering. One option involves a tie-up with Tesla, while another centers on xAI. These talks are still preliminary, and no agreement has been reached, but investors welcomed the possibility of deeper cooperation across the group.

The market reaction was swift. After falling to its lowest level in two months on Thursday, Tesla rebounded strongly in early Friday trading. The rally lifted the company’s valuation back toward $1.65 trillion, signaling renewed confidence in Musk’s long-term strategy despite recent financial pressures.

Much of that optimism reflects the potential overlap between the companies’ ambitions. Musk has repeatedly floated the idea of using SpaceX technology to support large-scale computing in orbit, which could benefit xAI’s push to expand its artificial intelligence systems. Tesla, meanwhile, could contribute through its battery, energy storage, and manufacturing operations, creating a tightly linked ecosystem spanning transportation, robotics, space, and AI.

Financial ties between the firms have already been growing. Tesla recently committed $2 billion to xAI, matching a similar investment made earlier by SpaceX. In a shareholder letter, Tesla said, “As set forth in Master Plan Part IV, Tesla is building products and services that bring AI into the physical world. Meanwhile, xAI is developing leading digital AI products and services, such as its large language model (Grok).”

Musk reinforced that view during the earnings call, arguing that collaboration is central to Tesla’s future. “But if there are things xAI can help accelerate our progress, then why should we not do that?” he said. “And that is the reason why we’ve gone ahead with such an investment. Because this is part of the strategic initiative.” The company has also highlighted links between AI development, its Optimus robots, and autonomous driving systems.

Still, significant uncertainty surrounds any potential deal. People close to the matter say the companies may ultimately decide against merging, and any transaction could complicate SpaceX’s plans for a major stock market debut later this year. That offering, if it moves forward as expected, could be one of the largest in history.

The surge in Tesla’s share price also comes as the company faces near-term challenges. Recent earnings showed weaker profitability, and management has warned that heavy spending is coming as it ramps up investments in autonomy and robotics.

Musk acknowledged the scale of those plans, saying, “This year for Tesla is the first major steps as we increase vehicle autonomy and begin to produce Optimus robots at scale — we’re making very, very big investments.” For now, investors appear to be focused less on short-term risks and more on the possibility that Musk’s interconnected vision could unlock new sources of growth.
