Elon Musk said SpaceX could potentially reach a $1 quadrillion valuation and indicated a 65% likelihood of a merger with Tesla before 2028, rekindling speculation over the relationship between his two companies. SpaceX, which trades under $SPCX following its 2026 IPO, was valued at approximately $2.15 trillion in the latest account, far below Musk's long-term target. Market odds of a Tesla-SpaceX merger by January 1, 2028 rose to 59.5% YES, though neither company has confirmed merger plans through formal announcements or filings. Musk has previously cited potential synergies between Tesla and SpaceX, while presenting Starship as a platform for future markets including asteroid mining, in-orbit manufacturing and Mars transport.
