Shares of Tesla (TSLA) experienced a 3.57% decline Monday following a weekend announcement from OpenAI CEO Sam Altman revealing his company’s entry into the robotics sector. By midday Monday, the stock was trading at $420.23.

Via a post on X, Altman revealed that OpenAI is actively recruiting talent to develop OpenAI Robotics, concentrating on hardware engineering, control systems, integration, and machine learning applications for humanoid robots. His stated objective: deploy robots to assist skilled labor on infrastructure initiatives initially, followed by eventual consumer-level personal robots.

This strategic direction places OpenAI squarely in competition with Tesla’s existing efforts.

Tesla has been restructuring its Fremont manufacturing operations to prioritize Optimus. The company discontinued Model S and Model X production in early May 2026 to reallocate that assembly capacity for humanoid robots. This factory conversion is projected to conclude in late July or August, with Fremont aiming for annual manufacturing capacity approaching 1 million units.

Elon Musk has consistently characterized Optimus as the vehicle for Tesla achieving a multitrillion-dollar market capitalization. However, before mass production even commences, the program now confronts a well-capitalized AI-focused competitor.

This marks another chapter in the ongoing tension between Musk and Altman. Musk previously initiated legal proceedings against Altman regarding OpenAI’s structural transformation from nonprofit to for-profit status. A jury ruled in Altman’s favor last month.

Optimus Development Schedule Faces New Dynamics

Tesla currently operates several Optimus Gen 3 prototypes within its facilities—including Gigafactory Texas and Fremont—where they perform repetitive operations such as battery component assembly. However, volume production remains pending.

The Gen 3 public unveiling is scheduled for late July through early August, consistent with Musk’s timeline provided during Tesla’s Q1 earnings discussion. The installation of Optimus production equipment at Fremont was announced for Q2, with full-scale manufacturing commencing later this year.

OpenAI’s market entry at this juncture creates a perception challenge for Tesla: Optimus no longer stands as the sole credible AI-powered robotics investment opportunity in the market.

SpaceX Public Offering Complicates Musk’s Narrative

Musk currently manages multiple significant initiatives. SpaceX is preparing for a Nasdaq listing under ticker SPCX in mid-June, pursuing a valuation between $1.75 trillion and $2 trillion while raising up to $75 billion—potentially establishing it as the largest IPO on record. Musk maintains approximately 42% equity ownership and 85% voting control.

Tesla’s Q1 regulatory filing disclosed a $2 billion equity position in SpaceX. The companies are jointly developing a semiconductor fabrication facility in Texas, designated Terafab, and collaborating on orbital data center infrastructure.

Wedbush analyst Dan Ives has assigned an 80% likelihood to a Tesla-SpaceX merger occurring in 2027.

Tesla’s Q1 documentation confirmed the $2 billion SpaceX investment. The Fremont Optimus production line transition is scheduled for completion in late July or August.
