TLDR
- Tesla commits $2 billion to Elon Musk’s xAI through Series E Preferred Stock agreement signed January 16
- Company plans to cease Model S sedan and Model X SUV production, redirecting factory capacity to humanoid robots
- Cybercab robotaxi production timeline maintained for 2026 despite history of missed autonomous vehicle targets
- Fourth-quarter energy storage business generated record $3.84 billion, exceeding analyst projections by $380 million
- Annual capital spending projected to surpass $20 billion in 2026, jumping from $8.5 billion previous year
Tesla announced a $2 billion stake in xAI, officially connecting the EV maker with Musk’s artificial intelligence venture. The deal closed January 16, 2026, with Tesla purchasing xAI Series E Preferred Stock.
The partnership formalizes what investors anticipated for months. Tesla gets access to xAI’s advanced AI models while xAI benefits from Tesla’s resources and data. Both companies plan to collaborate on AI development.
This investment underscores Tesla’s transformation from electric vehicle manufacturer to AI-focused technology company. The company’s valuation of roughly $1.5 trillion depends heavily on this strategic shift succeeding.
Tesla confirmed Cybercab robotaxi production continues as planned for 2026. Musk projects fully autonomous vehicles operating in one-quarter to one-half of U.S. states by year-end.
The company currently operates limited robotaxi service in Austin, Texas. Previous predictions about nationwide rollouts haven’t materialized on schedule. Musk originally targeted half the U.S. population by end of 2025, later adjusting to eight to ten major metro areas.
Vehicle Lineup Gets Pruned
The Model S and Model X will be discontinued. These premium vehicles established Tesla’s reputation but now generate minimal revenue compared to Model 3 and Model Y sales. Freed-up production lines will manufacture Optimus humanoid robots instead.
Tesla reported its first annual revenue drop in company history. Full-year 2025 revenue declined 3% to approximately $94.83 billion. The automotive business struggles against competitors offering newer vehicles at aggressive prices.
The federal EV tax credit expired. Musk’s political involvement has turned off some potential buyers. Tesla responded with discounting strategies and cheaper vehicle variants to maintain sales volume.
Analysts project 1.77 million vehicle deliveries in 2026, representing 8.2% growth.
Stronger Margins, Weaker Profits
Fourth-quarter adjusted earnings hit 50 cents per share, topping the 45-cent consensus estimate. Net income dropped 61% to $840 million for the quarter.
Automotive gross margin excluding regulatory credits improved to 17.9% from 13.6% one year prior. This crushed expectations of 14.3%. The margin expansion happened despite falling sales and aggressive discounting.
Energy storage delivered standout performance. The division generated $3.84 billion in Q4 revenue, up 25.5% year-over-year. Analyst estimates called for $3.46 billion. Grid-scale battery demand remains strong as utilities add renewable energy capacity.
CFO Vaibhav Taneja said 2026 capital expenditures will top $20 billion. That’s 2.4 times the $8.5 billion invested in 2025. Money will fund Cybercab factories, robot production lines, Semi truck facilities, and Roadster development.
Shares jumped 3.5% after-hours before retreating to 1.8% gains once spending plans became clear.
Musk raised concerns about memory chip availability. He suggested Tesla might build its own semiconductor fabrication plant. Tech companies building AI infrastructure have consumed available chip supply, driving prices higher.
Optimus robot production won’t reach volume levels until late 2026. Cybercab faces regulatory challenges since federal safety standards mandate steering wheels and pedals.
Musk hasn’t specified when Full Self-Driving will receive regulatory approval for unsupervised operation. He’s predicted rapid autonomous driving progress for nearly ten years.
Tesla stock gained 11% during 2025. Musk’s $878 billion compensation package, linked to performance targets, reassured investors about his focus on Tesla versus other ventures.
