Tesla invests $2 billion in xAI as Cybercab production target stays on track

Summary
- Tesla to invest $2 billion in Elon Musk’s AI venture xAI
- Company says Cybercab robotaxi production will begin this year
- Energy storage division delivers record quarterly revenue
- Capital spending set to more than double in 2026
Tesla is doubling down on artificial intelligence, announcing a $2 billion investment in xAI, Elon Musk’s AI startup, while reaffirming that production of its long-promised Cybercab robotaxi remains on schedule for this year. The move underscores Musk’s broader effort to reposition Tesla from a traditional electric vehicle maker into a company centered on AI, robotics and autonomous mobility.
The investment aligns with a strategy that investors increasingly view as central to supporting Tesla’s roughly $1.5 trillion valuation. At the same time, delivering on Cybercab production is seen as critical for rebuilding credibility after several missed timelines tied to autonomous driving initiatives.
Heavy spending signals transition phase
Tesla’s ambitions come with a steep price tag. Chief Financial Officer Vaibhav Taneja said capital expenditures would exceed $20 billion this year, more than double 2025’s spending, as Tesla ramps up factory investments for Cybercabs, humanoid robots, the Semi truck and the next-generation Roadster.
Shares initially rose in after-hours trading before paring gains as investors digested the higher spending outlook.
Analysts say Tesla is entering a transition phase, asking markets to value future revenue from self-driving software and robotaxi services even as its core EV business faces slowing growth. Musk said fully autonomous driving capability would gradually expand across large parts of the United States, though previous rollout targets have frequently slipped.
Core auto business under pressure
Tesla’s traditional vehicle business continues to face intensifying competition and pricing pressure worldwide. The company confirmed it will discontinue the Model S and Model X — once its flagship models — freeing factory capacity for robotics-related production.
Annual revenue declined about 3% in 2025, marking Tesla’s first yearly sales drop. To support volumes, the automaker leaned on discounts and introduced lower-priced trims. Analysts expect deliveries to rebound modestly in 2026.
Fourth-quarter adjusted earnings came in at 50 cents per share, beating expectations, while automotive gross margins (excluding regulatory credits) improved to 17.9%, pointing to cost efficiencies despite softer demand. However, quarterly net income fell sharply from a year earlier.
Energy business shines
A key bright spot was Tesla’s energy generation and storage division, which continues to benefit from global demand for grid-scale battery systems supporting renewable energy infrastructure.
Revenue in the segment surged 25.5% to a record $3.84 billion in the fourth quarter, well above market expectations.
AI push brings both promise and risk
Investors remain focused on Tesla’s AI and robotics roadmap. Musk said production of the Optimus humanoid robot would scale gradually, with meaningful volumes likely only toward the end of 2026.
He also warned of potential memory-chip shortages, suggesting Tesla may eventually need to invest in chip manufacturing to secure long-term supply.
Regulatory hurdles remain a major unknown for the Cybercab, which Musk envisions operating without a steering wheel or pedals — a design that would require approvals beyond current U.S. vehicle standards.
Still, enthusiasm around Tesla’s AI direction has supported its share price, with strong gains over the past year as investors weigh long-term autonomy and robotics opportunities against near-term execution risks.
Why This Matters
- Tesla is no longer pitching itself as just an EV company — it is asking markets to value it as an AI, robotics and autonomous services platform
- The $2 billion xAI investment tightens Musk’s AI ecosystem, linking model development directly to Tesla’s self-driving and robotics ambitions
- Cybercab delivery is a credibility test after years of delayed autonomy promises
- Rising capital spending raises execution risk, even as EV margins remain under pressure
- Energy storage is emerging as a powerful second growth engine alongside AI and autonomy
Together, these shifts will determine whether Tesla evolves into a dominant AI-driven mobility company — or struggles under the weight of massive spending and regulatory uncertainty.
