SpaceX Spends $329M on Tesla Megapacks for xAI Data Centers
In the second quarter, SpaceX significantly increased its investment in Tesla's Megapack battery storage systems, spending $295 million, and totaling $329 million for the year, according to Tesla's earnings report. This underscores the synergy between Elon Musk's enterprises, given that he serves as CEO and is the primary shareholder of both companies. In 2025, Musk's AI initiative, xAI, took over the social media platform X, and earlier this year, SpaceX acquired xAI. Previously, xAI's data centers had invested $430 million in Megapacks, with an additional $34 million spent in Q1. Furthermore, as of December 2025, SpaceX purchased $131 million worth of Tesla Cybertrucks. Megapacks are essential for providing backup power to meet the variable demands of AI data centers, helping to reduce expenses and maintain reliable operations.
