- xAI bought $269 million of Tesla Megapacks in April 2026, pushing its total Megapack spend to roughly $1 billion since 2024.
- xAI had spent $191 million in 2024 and $506 million in 2025 on Tesla Megapacks, plus $34 million in Q1 2026.
- xAI’s Colossus supercomputer in Memphis uses the Megapacks for grid‑scale battery storage, targeting about 1 GWh of buffering capacity to support its 2 GW compute goal.
- Tesla recognized $573 million in revenue from SpaceX and xAI in 2025, about 4.5 % of its total energy‑division sales.
- xAI runs nearly 50 natural‑gas turbines at its Mississippi data center and plans a 41‑turbine gas plant, potentially emitting over 6 million tons of CO₂ per year.
- xAI also bought $131 million of Cybertrucks in 2025 and $147 million of other Tesla goods and services that year, showing broader inter‑company transactions.
Why it matters: Tesla’s energy division gains $573 million—about 4.5% of its 2025 energy revenue—from xAI’s Megapack orders, while xAI’s reliance on natural‑gas turbines for its 2 GW compute push threatens Tesla’s clean‑energy narrative and could boost xAI’s carbon footprint unless renewable power is added.
