Musk Expands Lawsuit Against OpenAI and Adds Microsoft as Defendant

Elon Musk, the billionaire entrepreneur, has significantly expanded his lawsuit against OpenAI, the company behind ChatGPT, by adding Microsoft as a defendant and introducing federal antitrust claims. The amended lawsuit, filed on Thursday night in federal court in Oakland, California, alleges that Microsoft and OpenAI have illegally sought to monopolize the market for generative artificial intelligence and sideline competitors 123.

Key Allegations and Demands

The expanded lawsuit accuses OpenAI and its CEO, Samuel Altman, of violating contract provisions by prioritizing profits over the public good in their pursuit of AI advancement. Musk's complaint states, "Never before has a corporation gone from tax-exempt charity to a $157 billion for-profit, market-paralyzing gorgon -- and in just eight years" 123.

The lawsuit seeks to:

  1. Void OpenAI's license agreement with Microsoft
  2. Force both companies to divest what it calls "ill-gotten" gains
  3. Address alleged antitrust violations in the AI market 123

Antitrust Claims and Competitive Practices

Musk's legal team argues that OpenAI and Microsoft have violated antitrust laws by:

  1. Conditioning investment opportunities on agreements not to deal with rival companies
  2. Engaging in an exclusive licensing agreement that allegedly amounts to a merger without proper regulatory approvals 23

The lawsuit also claims that the partnership between OpenAI and Microsoft has allowed them to exchange "competitively sensitive information" 4.

OpenAI and Microsoft's Response

OpenAI has dismissed the expanded lawsuit, stating that it is "even more baseless and overreaching than the previous ones" 123. Microsoft has declined to comment on the allegations 13.

Background and Context

Musk, who co-founded OpenAI, has long opposed the company's current direction. The startup has become a leader in generative AI, largely due to billions of dollars in funding from Microsoft 123. This lawsuit is part of an ongoing legal battle, with Musk's original complaint filed in August 2024 12.

The expanded lawsuit now includes additional defendants:

  • LinkedIn co-founder Reid Hoffman
  • Microsoft VP Dee Templeton, who previously served on OpenAI's board 4

Musk's AI Ventures and Political Connections

While pursuing this lawsuit, Musk has been developing his own AI initiatives. In July 2024, his xAI startup opened a large supercomputing facility in Memphis, Tennessee, to train the AI chatbot Grok 4.

Interestingly, the lawsuit mentions Musk's increased prominence in the incoming Trump administration, noting his appointment to a role focused on reducing government waste 235.

Industry Implications

This legal battle highlights the intense competition and high stakes in the rapidly evolving AI industry. As major tech companies and startups vie for dominance in generative AI, the outcome of this lawsuit could have significant implications for market dynamics, partnerships, and regulatory scrutiny in the sector 12345.
