Lyten said it secured more than $200 million in additional equity investment on July 28, 2025, bringing total capital raised to over $625 million. The company said the new money supports recent acquisitions and broader expansion plans.
Stellantis Ventures invested in Lyten to accelerate commercialization of Lyten 3D Graphene applications, including the LytCell lithium-sulfur EV battery, lightweighting composites, and on-board sensing. Stellantis said lithium-sulfur batteries can deliver more than twice the energy density of lithium-ion and avoid nickel, manganese, and cobalt cathodes.
Lyten says its lithium-sulfur battery offers an alternative non-nickel-manganese-cobalt cathode solution for EV manufacturing, where traditional battery materials are in critically short supply. The company is initially producing batteries, composites, and sensors on a 145,000-square-foot campus in Silicon Valley.

Pre-IPO investments carry significant risks. Lyten shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. The investment is speculative in nature, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.
In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.
There are two primary exit paths for pre-IPO holdings: selling your shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.
The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. Investors only pay transaction-related fees when they complete an investment.

This estimate is not investment advice and may differ substantially from the price at which shares actually trade.
