Musk says Tesla, Samsung sign $16.5 billion chip supply deal
Samsung's shares jumped as much as 6.8 per cent to their highest since September last year after news of the deal.
Musk said Samsung's new chip factory in Taylor, Texas will make Tesla's next-generation AI6 chip, potentially re-energizing the project that has faced long delays amid Samsung's difficulties in retaining and attracting major clients.
"Samsung agreed to allow Tesla to assist in maximizing manufacturing efficiency. This is a critical point, as I will walk the line personally to accelerate the pace of progress. And the fab is conveniently located not far from my house," Musk said in a post on X on Monday.
"The $16.5B number is just the bare minimum. Actual output is likely to be several times higher," he said in another post.
According to a senior analyst at NH Investment & Securities, Ryu Young-ho, Samsung's Taylor fab "so far had virtually no customers, so this order is quite meaningful".
In October, Reuters reported that Samsung had postponed taking deliveries of ASML chipmaking equipment for its Texas factory as it had not yet won any major customers for the project. It has already delayed the plant's operational start to 2026.
POTENTIAL PRODUCTION TIMELINE
While no timeline was provided for AI6 chip production, Musk has previously said that next-generation A15 chips will be produced at the end of 2026, suggesting A16 would follow.
Lee Dong-ju, an analyst at SK Securities, expects production in 2027 or 2028, but Tesla has a history of missing its targets.
Samsung currently makes Tesla's A14 chips, which power its Full Self-Driving driver assistant system, while TSMC is slated to make the AI5, initially in Taiwan and then Arizona, Musk has said.
Samsung, the world's top memory chip maker, also produces logic chips designed by customers through its foundry business. The Texas project is central to Samsung Chairman Jay Y. Lee's strategy to expand beyond its bread-and-butter memory chips into contract chip manufacturing.
Samsung currently holds just 8 per cent of the global foundry market, far behind industry leader TSMC, which has a 67 per cent share, data from market researcher Trendforce show.
Samsung had earlier announced the $16.5 billion chip supply deal without naming the client, saying the customer had requested confidentiality about the details of the deal, which will run through the end of 2033.
Three sources briefed about the matter told Reuters that Tesla was the customer for the deal.
HELP SAMSUNG'S FOUNDRY BUSINESS
The deal with Tesla comes as Samsung, which is due to report its earnings on Thursday, faces mounting pressure in the race to produce artificial intelligence chips, where it trails rivals such as TSMC and SK Hynix. This lag has weighed heavily on its profits and share price.
Pak Yuak, an analyst at Kiwoom Securities, said the deal would help reduce losses at Samsung's foundry business, which he estimates exceeded 5 trillion won ($3.6 billion) in the first half of the year.
Analysts say Samsung has struggled to retain key clients, with many defecting to TSMC for advanced chips, underscoring technological challenges the firm faces in the race to stay relevant in the capital intensive business.
TSMC counts Apple, Nvidia and Qualcomm among its customers.
It is not clear whether the Samsung-Tesla deal is related to ongoing trade talks between South Korea and the United States. Seoul is seeking U.S. partnerships in chips and shipbuilding amid last-ditch efforts to reach a trade deal to eliminate or reduce potential 25 per cent U.S. tariffs.

LG Innotek to take stake in lidar maker Aeva as part of $50 million deal
SAN FRANCISCO :Aeva Technologies said on Tuesday that South Korean camera module maker LG Innotek will take an equity stake in Aeva as part of a $50 million strategic collaboration. Aeva makes lidar sensors that help vehicles and industrial equipment gain a detailed three-dimensional view of their environment and detect how fast surrounding objects are moving. It supplies sensors to vehicle firms such as Daimler Truck and industrial equipment makers such as Nikon. As part of the deal, LG Innotek will make a $32 million equity investment in Aeva for a "single-digit percentage ownership" in the company, Aeva CEO Soroush Salehian told Reuters in an interview. The remainder of the deal will go toward building production capacity for sensors that can go into robotics and consumer devices, in addition to Aeva's existing markets of vehicles and industrial equipment. 'The ultimate goal of this partnership is for LG Innotek and Aeva to grow together as key players leading the next-generation lidar market through a long-term technology partnership that goes beyond the supply of products,' the South Korean electronics supplier's CEO, Hyuksoo Moon, said in a statement. Salehian told Reuters that Aeva is working to integrate its entire sensor into a single chip whose price can be driven low enough to make it viable in consumer electronics such as augmented reality headsets. "The roadmap that we're going towards is double-digit dollars," Salehian told Reuters. "We are already working towards the next generation that will allow for a very low-cost solution, which we think will be a game changer for mass adoption of what we call precision sensing."

Bank of Korea board members saw more interest rate cuts necessary, minutes show
SEOUL :Board members of South Korea's central bank said there was a need to lower interest rates, citing downward economic pressure from U.S. tariffs, at their latest meeting on July 10, minutes showed on Tuesday. The Bank of Korea kept its benchmark interest rate unchanged at 2.50 per cent at the meeting, but a majority of board members signalled another rate cut in the next three months and warned of "significant" economic uncertainty from U.S. tariffs.

Alphabet's Waymo to launch autonomous ride-hailing service in Dallas in 2026
ALPHABET'S Waymo will roll out its autonomous ride-hailing service in Dallas in 2026, accelerating its US expansion as electric vehicle maker Tesla pushes to grow its recently launched robotaxi business. After years of cautious growth, Waymo has recently increased its pace, launching in new cities through partnerships with ride-hailing platforms and fleet operators. In Dallas – a city in the north of Texas – Waymo will operate through a new multi-year partnership with car rental company Avis Budget Group, which will manage fleet operations, including maintenance and depot infrastructure, Waymo said in a blog post on Monday (Jul 28). Waymo currently serves more than 250,000 paid trips every week with about 1,500 vehicles in major US cities such as Phoenix, San Francisco, Los Angeles and Austin. This year, Waymo began its service in Austin exclusively on the Uber platform, months before Tesla started a limited robotaxi trial in the city with about a dozen Model Y SUVs and a human safety monitor in the front passenger seat. Tesla chief executive officer Elon Musk has said the company will rapidly expand its robotaxi services to other US cities and is seeking regulatory approval from the states of California, Nevada, Florida and Arizona.

Sign Up Sign Up Commercialising autonomous vehicles has been challenging, with several companies such as GM's Cruise shutting down after collisions, recalls and federal investigations. Amazon-backed Zoox is among the few still operating and is preparing to launch commercial services later this year. Until Tesla's Austin trial, Waymo was the only company to operate paid driverless taxis in the US. Rides will be available through the Waymo app. The company is also planning launches in Miami and Washington, DC in 2026 as part of its broader rollout across the US. The collaboration is part of Avis' broader strategy to evolve from a traditional rental car company into a mobility services provider. REUTERS
