Recent reports have suggested that Tesla and Samsung SDI are in talks over a potential partnership to supply batteries for large-scale energy storage systems (ESS). 

The update was related by industry sources and initially reported by South Korean news outlets. 

ESS batteries to be built at Samsung’s Indiana plant

As noted in a report from Korea JoongAng Daily, the demand for energy storage systems has been growing rapidly in North America, thanks in no small part to the surge in AI investments across numerous companies. With this in mind, Tesla has reportedly approached Samsung SDI about a potential battery supply deal.

The deal is reportedly worth over 3 trillion Korean won (approximately $2.11 billion) and will span three years, according to The Korea Global Economic Daily. A battery supply deal with Samsung SDI could make sense for Tesla as the company already has a grid-scale battery, the Megapack, which is perfect for industrial use. Samsung SDI could simply supply cells for the EV maker.

Production of the batteries would reportedly take place at Samsung SDI’s joint venture factory with Stellantis in Indiana, which is currently under construction. Samsung SDI recently announced plans to use part of that plant’s EV lines to produce cells for ESS, with a targeted capacity of 30 GWh by the end of next year.

Tesla and Samsung’s partnership

At present, only a handful of manufacturers, including Korea’s LG Energy Solution, Samsung SDI, SK On, and Japan’s Panasonic, are capable of producing energy storage-scale batteries domestically in the United States. A Samsung SDI official issued a comment about the matter, stating, “Nothing has been finalized regarding cooperation with Tesla.”

The possible energy storage system deal adds another layer to Tesla’s growing collaboration with Samsung, which is already in line as a partner in the upcoming production of Tesla’s AI5 and AI6 chips. Early sample manufacturing of the AI6 is expected to begin in South Korea, with mass production slated for Samsung’s Texas-based Taylor foundry when it starts operations.

The AI6 chip will power Tesla’s next wave of high-volume projects, including the Optimus humanoid robot and the autonomous Cybercab service. Musk has called the partnership with Samsung a “real collaboration,” adding that he personally plans to “walk the line” at the Taylor facility to speed up progress.

Elon Musk recently revealed new details about Tesla’s next-generation AI5 chip while hinting at even more advanced iterations of its custom silicon. 

Based on the CEO’s post, it appears that Tesla is already exploring generations as far ahead as AI8.

Elon Musk teases Tesla’s chip development

In his X post, Musk stated that he had just completed a design review with Tesla’s chip engineers in California and Texas for the company’s upcoming AI5 chip. This was not surprising at all, considering that Musk has been discussing AI5 for quite some time now. What was surprising, however, were his comments that followed.

“And AI6 and AI7 will follow in fast succession. AI8 will be out of this world,” he wrote in his post, adding in a follow-up that his chip design review would be continuing the next day, followed by an Optimus demo review.

Considering that Tesla is currently rolling out a Robotaxi service using cars that are equipped with AI4 chips, some industry watchers have expressed interest in why the company is developing several generations’ worth of silicon for the company’s products. Inasmuch as AI4 might be enough for FSD and the Robotaxi rollout today, however, products such as Optimus might benefit from a more advanced chip. 

Even AI5 will already be insanely impressive

During Tesla’s Q3 2025 earnings call, Musk described AI5 as “an amazing design” that represents a full evolution from the AI4 chip currently used in its vehicles and data centers. The new hardware, which will be manufactured by both Samsung in Texas and TSMC in Arizona, is expected to deliver up to 40x performance gains compared to its predecessor.

Tesla’s in-house engineering team redesigned the chip from the ground up, removing traditional components such as GPUs and image signal processors to improve efficiency and power måanagement. Musk said the chip now fits within a half-reticle design, calling it “a beautiful chip” into which he’s “poured so much life energy.”

Musk confirmed Tesla’s plan to create an oversupply of AI5 chips that could power not only vehicles but also humanoid robots and data centers. He emphasized that Tesla’s vertically integrated approach, designing both hardware and software, gives it a unique edge in scaling AI applications.

Tesla will soon offer a gifting program for its Full Self-Driving (Supervised) suite, allowing people to gift a subscription to the semi-autonomous driving software for a variety of timeframes.

The idea would allow people to gift Full Self-Driving as a trial, potentially shifting them to subscribe or even buy the software outright if they find it useful.

Tesla is overhauling its Full Self-Driving subscription for easier access

FSD is a pretty difficult thing to not use once you have it, and while you still have to pay attention, and it has its shortcomings, it takes a lot of the stressors out of driving.

Tesla executive Raj Jegannathan said the company would be shipping the gifting program out before the holidays, making a great gift for owners just in time for Christmas.

Will have it ready before holidays!

Full Self-Driving is Tesla’s semi-autonomous driving platform that is currently among the most robust options on the market. As a personal user, I find it to be an extremely beneficial feature that I use on a daily basis.

While Tesla does offer gift cards, this would be a great option to choose the present you’re giving to a family member or friend.

Tesla offers a subscription to Full Self-Driving in the United States for $99 per month; it gives people an opportunity to try the suite for a month and is more affordable in the short term for those who cannot swing the current $8,000 fee to purchase it outright.

CEO Elon Musk has advised every Tesla owner to purchase the suite outright. In 2020, he confirmed that a subscription program would be released, but he said, “It will be economically better to have bought FSD.”

He continued in 2021, stating that “buying FSD will still be a better long-term deal than subscription.

He has also said that the monthly subscription price could rise as FSD goes to wide release, but that has yet to happen. In fact, it was originally $199 a month, but Tesla decreased the price to $99. We’re hopeful it doesn’t get more expensive.
