Tesla Profits Plunge 61% as Musk Bets Company's Future on AI and Robots

Massive Earnings Drop Shakes Tesla's Financial Foundation

Tesla's fourth-quarter net income plunged 61% to $840 million, or 24 cents per share, from $2.1 billion, or 60 cents per share, a year earlier, as operating expenses jumped 39%. For the full year 2025, profits plummeted a whopping 46% year-over-year, from $7.1 billion to $3.8 billion. This marks the first time on record the company has recorded an annual revenue decline.

Tesla said some of the increase in costs was "driven by AI and other R&D projects." The company warned that 2026 capital expenditures will exceed $20 billion as it funds new factories, expands battery production, builds AI compute infrastructure, and ramps up manufacturing for Cybercab, Semi, Megapack, and Optimus. This represents Tesla's weakest annual performance since the depths of the pandemic.

Despite the financial hit, Tesla's stock rose modestly in after-hours trading, suggesting investors remain optimistic about the company's ambitious pivot away from traditional automaking.

Auto Sales Decline as Competition Intensifies

Tesla delivered 418,227 vehicles in the quarter, down ~16% year-over-year, bringing the full-year 2025 total to 1.63 million. This marks the second consecutive year of declining volume, driven by intense competition in China and subsidy withdrawals in key markets like the US and Europe. Revenue in the fourth quarter slid 3% from $25.7 billion a year earlier, with the auto segment falling 11% to $17.7 billion from $19.8 billion.

Tesla, once the undisputed global leader in electric vehicle sales, has lost that crown as its brand reputation has soured and competition — particularly from China — has grown more intense. Tesla's 2025 auto sales fell nine percent, reflecting increased competition from rivals and blowback to Musk's embrace of Trump and far-right political figures.

The company's automotive gross margins remain under intense pressure from price cuts implemented to maintain market share in an increasingly crowded EV landscape.

$2 Billion Bet on AI Through xAI Investment

Tesla said that on Jan. 16, it entered into an agreement to invest about $2 billion in Musk's AI startup, xAI, "as part of their recent publicly-disclosed financing round." The xAI investment, along with a partnership with the company, is "intended to enhance Tesla's ability to develop and deploy AI products and services into the physical world at scale."

There's no better symbol of Tesla's strategic shift than one piece of news that Musk dropped on Tesla's earnings call: The automaker is discontinuing the Model S and Model X to make more room to build Optimus robots. Production of the Model S and X is to wind down next quarter, with their Fremont factory space handed over to Optimus. Musk described the move as "slightly sad," while sketching a future where the site produces up to a million humanoid robots a year instead.

The High-Stakes Transformation

The company describes itself as in "transition from a hardware-centric business to a physical AI company." Musk used the earnings call to roll out a freshly polished mission statement built around "amazing abundance," arguing that advances in AI and robotics will reshape society – and, in his telling, deliver "universal high income" rather than basic income.

For Tesla, the warning lights are on. Revenue is shrinking, profits are under pressure, and the car business is losing momentum. Musk's answer is to proclaim that "the future is autonomous," and the market appears to have bought the story. Whether this massive bet on AI and robotics will pay off remains to be seen, but Tesla is clearly wagering its entire future on technologies that are still years away from mass market reality.
