Tesla has struck a US$4.3 billion supply deal with LG Energy Solution for lithium iron phosphate (LFP) batteries. These batteries will be used in Tesla’s U.S. energy storage systems, but not in vehicles, with production beginning in August 2027 at LG’s U.S. facilities.
This deal marks Tesla’s second major partnership with a South Korean firm this month. Earlier, Tesla signed a US$16.5 billion semiconductor agreement with Samsung Electronics. LG, without naming Tesla, had revealed a 5.9 trillion won overseas LFP contract which allows for a contract extension by up to seven years and potential increases in supply.
The agreement supports LG Energy’s plan to enhance its energy storage market presence in the U.S. as competition with Chinese battery producers grows. Additionally, LG has commenced LFP battery production at its Michigan plant, with plans for further expansion through its joint venture facility with General Motors in Tennessee.
This news secures a critical part of Tesla’s supply chain for its energy division, but with production not starting until 2027, the direct financial impact is distant. We saw Tesla’s energy storage deployments hit a record 5.4 GWh in the second quarter of 2025, so locking in this future supply is a significant de-risking event. For traders in the coming weeks, this suggests any initial spike in Tesla’s stock price might be an opportunity to sell short-dated call options, as implied volatility could decrease once the long-term nature of the deal is fully priced in.
For LG Energy Solution, this agreement validates its strategy to expand in the U.S. and directly challenges Chinese competitors. This deal helps LG meaningfully compete with CATL, which held over 35% of the global EV and energy storage battery market at the end of 2024. Given that the deal leverages the Inflation Reduction Act’s tax credits, we might look at bullish option strategies on LG, anticipating sustained investor confidence in its North American growth plan.
This move, combined with the recent Samsung semiconductor deal, shows a clear pattern of securing supply chains with U.S. allies. We are looking at this as a long-term trend, especially after the volatility in lithium prices we observed back in 2023 and 2024 which highlighted supply chain vulnerabilities. A potential strategy could be a pair trade, going long on U.S. and South Korean suppliers benefiting from these partnerships while considering short positions on competitors who are being locked out of these key agreements.
