Tesla Signs Historic $4.3 Billion Contract with LG

The mystery is solved, Tesla is indeed behind the $4.3 billion mega-contract for 100% USA batteries.
Officially confirmed by the U.S. Department of the Interior during the Indo-Pacific Energy Security Summit, this deal puts an end to months of speculation that had been stirring the industry since July 2025.
From August 2027, LG Energy Solution (LGES) will produce LFP (lithium fer phosphate) units at its plant in Lansing, Michigan, a former joint venture with General Motors which LGES fully acquired in May 2025. The target capacity is 50 GWh/year. These batteries will exclusively power the Megapack 3, Tesla’s giant storage systems assembled in Houston, which currently have a total capacity of 47 GWh.
China is bad, Korea is good!
Why did everyone guess Tesla since the summer of 2025? LGES had announced a record contract of $4.3 billion with an anonymous “foreign client” for USA-made LFP. Reuters and Korean sources immediately pointed to Tesla, known as the world’s largest consumer of LFP for home and industrial storage. Until then, Tesla had been heavily dependent on the Chinese giant CATL, but the high tariffs on Chinese imports reinforced under the Trump administration made this dependence costly and risky. LGES, the only major player able to quickly ramp up production in the United States, ticked all the boxes thanks to its South Korean passport, which is highly regarded in Uncle Donald’s country. The timing aligned perfectly, and all that was left was to sign the contracts.

This three-year contract (August 2027 to July 2030) includes options for extension up to seven years and volume increases. For Tesla, it is a strategic security measure for its rapidly growing Energy division. For the United States, it is a giant step towards independence: viable domestic production at scale, a resilient supply chain against tariff shocks, better price stability, and the availability of grid-scale storage. A historic turning point that strengthens American energy sovereignty.
