U.S. Supreme Court to hear challenge on California emission rule waiver
The U.S. Supreme Court is set to hear a challenge from fuel companies against California’s ability to create its own emissions rules, in a case that could set a major precedent for how states handle making their own standards in efforts to lower greenhouse gas emissions through electric vehicle (EV) adoption.
After the Environmental Protection Agency (EPA) granted California an exemption from federal air pollution laws in 2022, effectively letting the state set its own vehicle emissions rules, the U.S. Supreme Court last week agreed to listen to a bid from a Valero Energy subsidiary and other fuel groups to challenge the exemption (via Reuters).
Valero’s Diamond Alternative Energy and other associated fuel business lobby groups argue that the waiver oversteps the power of the EPA under the Clean Air Act, under which the federal rules are set. The groups also argued that such a decision would lower demand for their liquid fuels, ultimately inflicting harm on their bottom line.

In the appeal, the groups also said that California was overstepping its power, acting as a “junior-varsity EPA” by making regulatory decisions to combat climate change and force the adoption of EVs upon consumers—choices the group says the state does not have the right to make.
The decision also comes after the EPA was backed by the U.S. Court of Appeals for the District of Columbia in April, with the court throwing out a legal challenge against the waiver from a group of 17 Republican-run states. In that appeal, backers also argued that California’s ability to set its own emissions rules gave the state unconstitutional regulatory power, which they said isn’t available to other states.
The waiver has long been a point of contention, originally dating back to a 2013 decision to offer California the waiver. In 2019, the Trump administration rescinded that waiver, before the EPA was given power to reinstate it under the Biden administration in 2022.
California has also been a leader in pushing EV adoption through massive incentives, and an official ruling later in 2022 to ban the sale of new gas cars beginning in 2035. That ruling has since been followed by a handful of other states, including New Jersey, New York, Oregon, and Washington.
Last year, California’s battery-electric vehicle (BEV) sales also made up around one-third of all U.S. BEV sales, as led by Tesla.
Passed by the California Air Resources Board (CARB), the California ban also includes a gradual phase-out of gas vehicles set to begin in 2026, for which the state also required an EPA waiver. California has gained over 75 separate waivers since 1967, through which it has been able to lodge increasingly strict rules surrounding vehicle emissions performance and EV sales.
In February, the EPA actually loosened federal standards requiring automakers to sell a certain ratio of EVs by 2032. Previously, the agency required that automakers make 60 percent of sales come from BEVs and plugin hybrids by 2030, increasing that to 68 percent by 2032. Now, the agency mandates that manufacturers make 50 percent of their overall sales either plugin hybrids or BEVs by 2030.

16:30 CT – Elon makes his opening statement and explains why Tesla changed its mission to “Amazing Abundance.” “With the continued growth of AI and robotics, I think we’re headed towards a future of universal high income,” Musk said, adding that along the way, Tesla will still be improving its products while keeping the environment safe and healthy.
16:34 CT – Elon noted that the first steps for this future are happening this year, thanks to Tesla’s autonomy and robotics programs, which will be launching and ramping this year. He also highlighted that Tesla will be making major investments this year, though the company will be very strategic when it comes to its funding. “I think it makes a ton of strategic sense,” Musk said.
16:36 CT – Elon also announces the end of the Model S and Model X programs “with an honorable discharge.” If you’re interested in buying a Model S or X, it’s best to do it now, Musk said. The Model S and Model X factory in Fremont will be replaced by an Optimus line. “It’s slightly sad, but it is time to bring the S and X program to an end. It’s part of our overall shift to an autonomous future,” Musk said.
16:38 CT – Elon discusses how Unsupervised FSD is now starting for the Robotaxi service. He noted that these Unsupervised Robotaxis don’t have any chase cars as of yesterday.

Tesla announces massive investment into xAI
“On January 16, 2026, Tesla entered into an agreement to invest approximately $2 billion to acquire shares of Series E Preferred Stock of xAI as part of their recent publicly-disclosed financing round,” it said.
Tesla has announced a major development in its ventures outside of electric vehicles, as it confirmed today that it invested $2 billion into xAI on January 16.
The move is significant, as it marks the acquisition of shares of Series E Preferred Stock, executed on market terms alongside other investors. The company officially announced it in its Q4 2025 Shareholder Deck, which was released at market close on Wednesday.
The investment follows shareholder approval in 2025 for potential equity stakes in xAI and echoes SpaceX’s earlier $2 billion contribution to xAI’s $10 billion fundraising round.
Tesla said that, earlier this month, it entered an agreement to invest $2 billion to acquire shares of Series E Preferred Stock of xAI:

CEO Elon Musk, who is behind both companies, is now weaving what appears to be an even tighter ecosystem among his ventures, blending Tesla’s hardware prowess with xAI’s cutting-edge AI models, like Grok.
Tesla confirmed the investment in a statement in its Shareholder Deck:
“On January 16, 2026, Tesla entered into an agreement to invest approximately $2 billion to acquire shares of Series E Preferred Stock of xAI as part of their recent publicly-disclosed financing round. Tesla’s investment was made on market terms consistent with those previously agreed to by other investors in the financing round. As set forth in Master Plan Part IV, Tesla is building products and services that bring AI into the physical world. Meanwhile, xAI is developing leading digital AI products and services, such as its large language model (Grok).”
It continued:
“In that context, and as part of Tesla’s broader strategy under Master Plan Part IV, Tesla and xAI also entered into a framework agreement in connection with the investment. Among other things, the framework agreement builds upon the existing relationship between Tesla and xAI by providing a framework for evaluating potential AI collaborations between the companies. Together, the investment and the related framework agreement are intended to enhance Tesla’s ability to develop and deploy AI products and services into the physical world at scale. This investment is subject to customary regulatory conditions with the expectation to close in Q1’2026.”
The history of the partnership traces back to xAI’s founding in July 2023, as Musk launched the company as a counterweight to dominant AI players like OpenAI and Google.
xAI aimed to “understand the true nature of the universe” through unbiased, truth-seeking AI. Tesla, meanwhile, has long invested in AI for its Full Self-Driving (FSD) software and Optimus robots, training models on vast datasets from its vehicle fleet.
The investment holds profound significance for both companies.
For Tesla, it accelerates its Master Plan Part IV, which envisions AI-driven autonomy in vehicles and humanoid robots. xAI’s Grok could enhance Tesla’s real-world AI applications, from optimizing battery management to predictive maintenance, potentially giving Tesla an edge over its biggest rivals, like Waymo.
Investors, on the other hand, stand to gain from this symbiosis. Tesla Shareholders may see boosted stock value through AI innovations, with analysts projecting enhanced margins and significant future growth in robotics. xAI’s valuation could soar, attracting more capital.
