Tesla in talks with Brazil-based startup to access lithium supply for EV batteries
Tesla is reportedly looking to strike a deal with Sigma Lithium Resources Group, a Brazilian startup company that can supply Tesla with lithium, a key ingredient of electric car batteries.
Sigma was granted a license to begin mining lithium by the Environmental Authority of the State of Minas Gerais, the Council of Environmental Policy on June 11, 2019. The license will allow Sigma to mine hard rock lithium, a crucial piece of automotive-grade lithium-ion batteries, for six-years, making the company an extremely valuable asset for automakers pursuing electric mobility.
It should be noted that Brazil was ranked No.7 among countries with the highest concentration of lithium. A large percentage of the metal, used primarily for the production of glass and batteries, is available in the Minas Gerais area.
Sigma has previously met with Tesla’s current lithium supplier, Ganfeng Lithium, a Chinese-based company that is currently the country’s largest supplier of the material. Tesla reportedly organized the meeting between both parties that unfortunately did not end in a deal. Sigma CEO Calvyn Gardner cited the Brazilian startup company could not meet the financial or production needs that Ganfeng requested.
“There’s a bunch of other things that they [Ganfeng] need, not just prices, but other demands which are a little more complicated that sort of restricts Sigma to almost supplying purely into China. It’s not really what we think we should be doing over the long term,” Gardner remarked at a mining conference in Brazil.
Gardner, who calls himself a “fan” of Tesla, was interested in purchasing a Model 3 for himself but ran into roadblocks as Tesla does not have a sales office in the South American country. After import taxes would have more than doubled the cost of the Model 3, he decided to hold off.
Striking a deal with Tesla would directly benefit both companies. Tesla currently uses Gigafactory partner Panasonic as its battery supplier but appears to be seeking to expand it lineup of partners, especially after the Japanese electronics conglomerate has cut its profit outlook due to China’s trade war with the US. Tesla’s acquisition of Maxwell Technologies, an ultracapacitor producer, also hinted at the electric car maker’s plans to pursue battery technology beyond its Panasonic partnership.
It would be beneficial for both Tesla and Sigma to strike a deal directly, with the Brazilian company shipping the lithium to the electric car maker. Unfortunately, this could only happen once makers of cathodes, another primary component of batteries, set up facilities in the United States.
Other large automakers that are bursting into the electric transportation market, such as Volkswagen and BMW, have held talks with Sigma already. Gardner, a graduate of the University of South Africa, is optimistic over the talks with both German automakers. “Having options to get lithium from other jurisdictions and that you can supply over the long term,” he said. “That’s what all of them are interested in and we think Sigma can do that.”
There is no shortage of money or optimism in the lithium mining industry. Sigma has recently received a $30 million loan from Japanese trading group Mitsui, according to Reuters. The money is planned to be used in building Sigma facilities, and will be repaid in a big way: a third of Sigma’s planned output of lithium from its Minas Gerais mining facility.

Tesla to improve one of its best features, coding shows
According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.
The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.
Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.
There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.
Tesla’s revolutionary Matrix headlights are coming to the U.S.
This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

xAI’s Grok approved for Pentagon classified systems: report
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.
Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.
Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards.
Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD.
Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible.
The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper
“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.
Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.
In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.
“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”
The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.
In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide.
Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.
Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.
In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.
