SpaceX has bought $329M worth of Tesla Megapacks so far this year

SpaceX has significantly increased its purchases of Tesla Megapack battery storage systems, spending $295 million in the second quarter and $329 million so far in 2026, as disclosed in its earnings report. The large-scale batteries are likely being deployed at data centers now operated under SpaceX after its acquisition of xAI, which previously bought $430 million worth of Megapacks for its AI infrastructure. The purchases highlight the interconnected nature of Elon Musk's businesses, as Musk leads both SpaceX and Tesla, while xAI's merger with SpaceX earlier this year consolidated resources. The Megapacks provide critical backup power that can respond in less than a second and help smooth out fluctuating power demands from AI training and inference, reducing costs and ensuring operational stability at data centers.
