Tesla disclosed a $2 billion investment in Elon Musk's xAI, joining a $20 billion financing round that values the AI startup at $230 billion. The investment proceeds despite an active shareholder lawsuit accusing Musk of breach of fiduciary duty for diverting Tesla's AI resources to his private company. Tesla justifies the move through Master Plan Part IV, claiming AI collaborations will enhance its autonomous driving and robotics ambitions.

The investment comes despite a controversial shareholder vote in November 2025 that technically rejected the measure. While 1.06 billion votes favored the investment and 916.3 million opposed it, abstentions counted as votes against under Tesla's bylaws, resulting in the measure's rejection

1

. Tesla proceeded anyway, justifying the decision through its Master Plan Part IV strategy. The company stated it is "building products and services that bring AI into the physical world" while xAI develops "leading digital AI products and services, such as its large language model" Grok chatbot

Existing Business Ties and AI Collaborations Framework

The $2 billion investment in xAI extends an already substantial business relationship between the companies. Tesla disclosed it sold $430 million worth of Megapack backup batteries to xAI in 2025, accounting for approximately 3.4% of Tesla's energy business revenue, which climbed 27% to $12.8 billion

Tesla and xAI entered into a framework agreement alongside the investment to evaluate potential AI collaborations between the companies

1

. Tesla emphasized that "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"

4

. The company highlighted its focus on physical AI and robotics, including plans for its Optimus humanoid robot, Cybercab robotaxis, and autonomous driving capabilities

Shareholders point to a critical conflict of interest: when Musk left OpenAI's board in 2018, he cited conflicts with Tesla's own AI efforts, then built Tesla's AI team, including the Dojo supercomputer and Full Self-Driving neural networks

.

After Musk's ownership stake in Tesla fell below 20% following his acquisition of Twitter, he incorporated xAI in March 2023 without immediately disclosing it to Tesla shareholders

4

. He revealed xAI publicly in July 2023 as an OpenAI competitor, describing it as a politically incorrect alternative

3

. The lawsuit seeks to force Musk to transfer his xAI ownership to Tesla, with shareholders now questioning whether Tesla should invest in the very company at the center of litigation while corporate governance concerns remain unresolved

.

Regulatory Scrutiny and Business Performance Context

xAI faces mounting regulatory investigations across multiple jurisdictions concerning its Grok chatbot and image generator, which enabled widespread nonconsensual creation and distribution of explicit deepfake images

3

. The European Commission initiated formal probes, as did agencies in California, Australia, India, Ireland, France, Malaysia, and Indonesia, with some countries suspending Grok until the company stops enabling production of content deemed illegal

4

.

Tesla's investment comes as the automaker reported revenue of $24.9 billion for the fourth quarter, beating analyst estimates of $24.79 billion, with adjusted earnings per share of 50 cents topping Wall Street targets of 45 cents

2

. However, profit fell 46% for the year, and total sales declined roughly 3% for the first time on record

3

. Tesla's automotive gross margin excluding regulatory credits reached 17.9%, well above expectations of 14.3%

2

. The investment is subject to customary regulatory conditions and expected to close in the first quarter of 2026
