Tesla (TSLA) is disclosing a massive investment in Elon Musk’s AI startup xAI as the automaker pushes deeper into AI-driven products linked to the physical world.
In its latest quarterly update report, Tesla confirms the xAI investment, which focuses on bringing artificial intelligence into real-world, physical applications across Tesla’s product lineup.
“On January 16, 2026, Tesla entered into an agreement to invest approximately $2 billion to acquire shares of Series E Preferred Stock of xAI as part of their recent publicly-disclosed financing round. As set forth in Master Plan Part IV, Tesla is building products and services that bring AI into the physical world. Meanwhile, xAI is developing leading digital AI products and services, such as its large language model (Grok).”
Tesla says the investment is paired with a framework agreement designed to formalize and expand cooperation between the two companies, particularly around evaluating future AI collaborations. The electric vehicle maker says it expects to seal the investment in the coming months.
“In that context, and as part of Tesla’s broader strategy under Master Plan Part IV, Tesla and xAI also entered into a framework agreement in connection with the investment. Together, the investment and the related framework agreement are intended to enhance Tesla’s ability to develop and deploy AI products and services into the physical world at scale. This investment is subject to customary regulatory conditions with the expectation to close in Q1’2026.”
The disclosure comes alongside a solid Q4 earnings report, where Tesla beat consensus expectations across the board.
Tesla posted revenue of $24.9 billion, slightly above estimates of $24.8 billion, while adjusted earnings per share came in at $0.50 versus expectations of $0.45.
Gross margin reached 20%, significantly ahead of the 17% analysts had forecast, and operating income totaled $1.4 billion, topping estimates of $1.3 billion.
TSLA is up over 3% in after-hours trading following news of the earnings beat.
