SpaceX significantly increased its acquisition of Tesla Megapacks in the second quarter of 2026, investing $295 million in the energy storage systems. These large-scale batteries are being deployed to bolster the power infrastructure for SpaceX’s burgeoning AI data centers, particularly its Colossus facilities located in the Greater Memphis area.

This substantial Q2 investment brings SpaceX’s total expenditure on Tesla Megapacks for the first half of 2026 to $329 million. The Megapacks, designed for utility and commercial applications, are crucial for ensuring stable energy supply. They function by storing energy from various sources, including renewables like solar and wind, and can provide backup power to prevent outages, a critical need for the intensive operations of AI data centers.

The expanded use of these energy storage solutions comes as SpaceX, led by Elon Musk, aims for rapid growth in its artificial intelligence infrastructure. Musk has indicated ambitious targets for power and cooling capacity, aiming for approximately 20 gigawatts online by the end of the following year, with a projected 15 gigawatts at the power plant level even if some projects face delays. This strategic procurement highlights the close operational ties between SpaceX and Tesla, both helmed by Musk, as the former seeks to secure robust energy solutions for its advanced technological pursuits.

In addition to the Megapacks, SpaceX’s data centers in Memphis also utilize natural gas-burning turbines for power generation. However, these turbines have drawn criticism and community opposition due to concerns over emissions, noise, and air pollution, leading to legal challenges. The NAACP has filed a federal lawsuit seeking to halt the use of these turbines without adequate pollution controls or permits.

Key Takeaways

• SpaceX spent $295 million on Tesla Megapacks in Q2 2026 to power its AI data centers.
• The total investment in Megapacks for the first half of 2026 reached $329 million.
• SpaceX aims to significantly expand its AI infrastructure's power and cooling capacity in the coming years.
