Tesla said on Wednesday it will invest $2 billion in CEO Elon Musk’s artificial-intelligence company xAI and that production plans for its Cybercab robotaxi were on track for this year.
The news supported Musk’s plan to pivot Tesla from an electric vehicle maker to an AI company, which is key to the company’s roughly $1.5 trillion valuation, while reassurance of production plans is critical for investor confidence as Tesla has repeatedly fallen short of promises made by Musk. But Musk’s plan to build Cybercabs as well as humanoid robots, along with Semi trucks and Roadster sports cars, will mean a series of factory investments that will take capital expenditures above $20 billion this year, Chief Financial Officer Vaibhav Taneja said. That is more than twice the $8.5 billion in 2025. Shares rose about 3.5% in after-hours trading, but pared gains following the capex details to trade up 1.8%.
Tesla is “entering a transition phase” where it is asking investors to underwrite potential revenue from self-driving software in its cars and robotaxi business before auto sales recover, said Thomas Monteiro, senior analyst at Investing.com.
“(That) makes rollout metrics – not deliveries – the most important leading indicator from here,” Monteiro said.
Musk, who has made a number of inaccurate forecasts about robotaxi rollout, said he expected to have fully autonomous vehicles in a quarter to half of the United States by the end of this year. He had said robotaxis would reach half of the U.S. population by the end of 2025, before later narrowing that goal to deployment in the top eight to 10 metropolitan areas. The company has since missed those targets with a limited robotaxi service in Austin, Texas. Tesla’s core EV business, which still accounts for most of the company’s current revenue, has been under strain as rivals roll out newer models, often at lower prices. A U.S. tax incentive for electric vehicles has also ended, and Musk’s far-right political rhetoric has alienated some customers.
On Wednesday, Musk told analysts on a conference call that Tesla would stop selling its Model S sedans and Model X SUVs; flagship vehicles that once established the company as a leader in the EV market but have since dwindled to account for a small fraction of revenue. The factory space will be used to build robots.
Tesla’s revenue fell about 3% to roughly $94.83 billion in 2025, marking the company’s first annual decline in revenue.
To defend volumes, Tesla has relied heavily on discounts and incentives, and introduced lower-priced trims of its best sellers. Wall Street expects the company to deliver 1.77 million vehicles in 2026, representing an 8.2% increase, according to Visible Alpha data.
Adjusted earnings per share of 50 cents in the fourth quarter topped Wall Street targets of 45 cents, according to LSEG data. Net income fell 61% to $840 million in the quarter.
Despite the sales drop, the company’s automotive gross margin excluding regulatory credits came in at 17.9%, up from 13.6% a year earlier and well above expectations of about 14.3%, according to Visible Alpha.
Its energy generation and storage business has proven a notable bright spot, benefiting from sustained demand for grid-scale batteries used to support renewable power and stabilize electricity networks.
Revenue from the energy generation and storage segment rose 25.5% to a record $3.84 billion in the December quarter, trouncing analysts’ estimates of $3.46 billion.
Investors have increasingly focused on Musk’s push into self-driving technology and robotics, with many looking for proof that the autonomy story is moving from promise to product.
An investment by Tesla in xAI was long expected. Analysts have said Tesla will benefit from xAI’s advanced models and growing valuation.
“With Tesla’s legacy EV business slowing, Tesla investors can take part in the scorching hot AI boom,” said Andrew Rocco, a stock strategist at Zacks Investment Research.
But Musk warned about a brewing shortage of memory chips that could hamstring Tesla’s plans in the coming years, adding that it should look to build a chip-making plant to protect itself.
“If we don’t do that, we’re just going to be fundamentally limited by supply chain,” he said. “In a worst-case geopolitical situation it would be quite a severe situation.”
The rapid build-out of artificial-intelligence infrastructure by U.S. tech firms has absorbed much of the world’s memory-chip supply, which has lifted prices as manufacturers prioritize components for higher-margin data centers over consumer devices.
Investors have also been looking for signs that Tesla’s Full Self-Driving and robotaxi rollouts are advancing, including updates on regulatory progress and clearer timelines for the purpose-built Cybercab, which is designed without a steering wheel or pedals.
Cybercabs will be added to its robotaxi service that currently relies on Model Y vehicles running a version of Full Self-Driving and will also be available for consumers to buy. Last week, Musk said initial production of the Cybercab robotaxi and the humanoid robot Optimus would be “agonizingly slow” before accelerating over time. On Wednesday, he said Tesla was not expecting significant Optimus production volume until the end of 2026.
There are also regulatory hurdles involved with producing the Cybercab, which Musk has said will have no steering wheel or pedals, contrary to current federal design standards.
He has continued to predict rapid progress for Full Self-Driving, a vision he has outlined for nearly a decade, but has not provided firm dates for regulatory approval or broad unsupervised deployment. Still, Tesla’s shares rose about 11% in 2025. An $878 billion pay package for Musk, pegged to a series of lofty operational and valuation milestones, reassured investors of his commitment to Tesla among his other business and political interests.

Madhu Gottumukkala, Acting Director and Deputy Director of the U.S. Cybersecurity and Infrastructure Security Agency (CISA), reportedly uploaded “sensitive” documents to a public version of ChatGPT in 2025, reported Politico, citing four officials from the Department of Homeland Security.
Details of the incident are still emerging, with the exact timeline of Mr. Gottumukkala’s ChatGPT usage and the results of an internal DHS review not yet confirmed.
However, the media outlet reported that Mr. Gottumukkala uploaded non-classified content that included CISA contracting documents intended for official use only. His activities were flagged in August, triggering a review.
The agency’s policy is to block access to ChatGPT by default unless an exception is granted, reported the outlet. However, one official alleged that Mr. Gottumukkala forced CISA to give him access to ChatGPT.
Public versions of AI chatbots often lack the advanced levels of cybersecurity controls mandated for government employee usage, raising concerns about uploaded content being viewed by AI companies, scraped, used in court proceedings, or even indexed online.
Listed as having over 24 years of experience in information technology per the CISA website, Mr. Gottumukkala “helps lead CISA’s mission to understand, manage, and reduce risk to the cyber and physical infrastructure that the American people rely on every day”.
Mr. Gottumukkala holds a Ph.D. in Information Systems from Dakota State University, an MBA in Engineering and Technology Management from the University of Dallas, an M.S. in Computer Science from the University of Texas at Arlington, and a B.E. in Electronics and Communication Engineering from Andhra University.

DeepSeek shook markets early last year with a set of AI models that rivaled some of the best offerings from the United States [File]

U.S. chipmaker Nvidia helped China’s DeepSeek hone artificial intelligence models that were later used by the Chinese military, the chairman of a U.S. House of Representatives committee said in a letter seen by Reuters on Wednesday.
DeepSeek shook markets early last year with a set of AI models that rivaled some of the best offerings from the United States but were developed with far less computing power, fuelling concerns in Washington that China could catch up with the U.S. in AI despite U.S. restrictions on the sale of high-powered computing chips to China.
In a letter to U.S. Commerce Secretary Howard Lutnick, Representative John Moolenaar, a Michigan Republican who chairs the House Select Committee on China, said documents obtained by the committee from Nvidia showed the achievement came after extensive technical assistance from Nvidia.
“According to NVIDIA records, NVIDIA technology development personnel helped DeepSeek achieve major training efficiency gains through an ‘optimized co-design of algorithms, frameworks, and hardware,’ with internal reporting boasting that ‘DeepSeek-V3 requires only 2.788M H800 GPU hours for its full training’ – less than what U.S. developers typically require for frontier-scale models,” Moolenaar wrote in the letter.
GPU hours are the number of hours an AI chip must run to train an AI model, while frontier-scale models refer to leading models produced by U.S. firms such as OpenAI, Anthropic or Alphabet’s Google.
The documents cover Nvidia activities from 2024. At the time Nvidia provided DeepSeek help, Moolenaar wrote, there was no public indication that DeepSeek’s technology was being used by China’s military.
“Nvidia treated DeepSeek accordingly – as a legitimate commercial partner deserving of standard technical support,” Moolenaar wrote.
Nvidia’s H800 chip was specifically designed for the China market and sold there before H800s were put under U.S. export controls in 2023. Reuters reported last year that U.S. officials believe DeepSeek is aiding China’s military.
“China has more than enough domestic chips for all of its military applications, with millions to spare. Just like it would be nonsensical for the American military to use Chinese technology, it makes no sense for the Chinese military to depend on American technology,” Nvidia said in a statement.
In a statement, Liu Pengyu, a spokesperson for the Chinese Embassy in the U.S., said: “China has all along opposed moves to overstretch the concept of national security or politicize trade and tech issues. We hope the U.S. can take concrete actions to keep global industrial and supply chains stable.”
The U.S. Commerce Department did not immediately respond to a request for comment. DeepSeek did not respond to a request for comment outside of business hours in China. Earlier this month, U.S. President Donald Trump’s administration approved sales of Nvidia’s H200 to China with some restrictions, including that the chips not be sold to entities that assist the Chinese military. The H200 is more powerful than the H800 chips DeepSeek used.
Trump’s decision drew fire from China hawks across the U.S. political spectrum over concerns the chips would supercharge Beijing’s military and erode the U.S. advantage in AI.
“If even the world’s most valuable company cannot rule out the military use of its products when sold to (Chinese) entities, rigorous licensing restrictions and enforcement are essential to prevent such assurances from becoming superficial formalities,” Moolenaar wrote.
“Chips sales to ostensibly non military end users in China will inevitably result in a violation of the military end use restrictions,” he added.

| Photo Credit: Special Arrangement
Food delivery platform Swiggy is now letting users order products with the help of agentic AI workflows. This means users on ChatGPT, Claude, and Google’s Gemini can place orders just by typing what they want into these AI chatbots. Underpinning this connection is the the open-source Model Context Protocol (MCP) that lets AI chatbots work with external services and platforms.
The integration covers Swiggy Food, Dineout, and Instamart, apart from letting users build carts, apply coupons, and track their deliveries directly through conversational AI tools. It will also enable users to get product recommendations, search for restaurants, compare options, add items to a cart, make use of coupons, reservations, and track deliveries.
Swiggy’s Instamart is said to be the first quick-commerce platform globally to adopt MCP.
To start ordering through the chatbots, users must connect the service with Claude, Gemini, ChatGPT, or other AI chatbot through a custom connector service or app, and provide the desired URL for integration.
“Conversational commerce” lets users “to simply express what they want, when they want it, whether it is to book a table at their favourite restaurant or order drinks and snacks for a match-viewing party,” said Madhusudhan Rao, Chief Technology Officer, Swiggy. “By bringing MCP to quick commerce, food delivery, and dining out, we’re removing friction from daily decisions and enabling a level of ease, personalisation, and joy that makes on-demand convenience feel effortless.”
