Away from Taiwan. Tesla has chosen Korean electronics giant Samsung as its partner for the production of next-generation microprocessors for its future vehicle technology systems. The agreement, worth USD 16.5 billion and valid until 2033, provides for the chips to be manufactured at Samsung's new plant in Taylor, Texas (Tesla is based in Austin), which is nearing completion and has an estimated production start-up date of 2026. The go-ahead had been scheduled for the end of this year, but there have been delays related to the yields of the advanced manufacturing process (state-of-the-art 2-nanometer chips, hyper-miniaturised and with a new, more efficient internal structure) and difficulties in finding high-profile customers. The move, however, pleased the market: Samsung +6.83% in Monday morning's session on the Seoul Stock Exchange. Tesla rallied with a 4.4 per cent top.

Partnership at a delicate time

The agreement comes at a difficult juncture for both companies. Tesla posted a 12 per cent year-on-year decline in revenues and a 16 per cent drop in net profit in the second quarter of the year, squeezing operating margins. Elon Musk spoke openly of 'some difficult quarters on the horizon', confirming that the path to new levels of automation will be longer than expected.

Samsung also finds itself in a complicated phase: the group's operating profit plummeted 56% in the second quarter, due to weakness in the semiconductor sector and delays in the approval of new high-capacity chips. The foundry division - the one that handles contract manufacturing - has been loss-making for several quarters, with plant saturation well below break-even.

Technology reshoring and US incentives

.

The decision to locate the production of the new chips in Texas reflects an established trend: bringing technology-intensive manufacturing activities to US soil. Samsung has benefited from the Chips and Science Act with direct incentives of 4.75 billion and a potential package of more than 9 billion in tax credits and financing.

For the electric car manufacturer, relying on a partner with a plant in the US means reducing exposure to tariffs and supply disruptions, as well as simplifying logistics. 'Samsung,' was Musk's comment on X, 'has agreed to allow Tesla to help maximise production efficiency. This is a critical point, as I will personally follow the line. And the factory is conveniently located not far from my home'. Tesla is based in Austin, Texas.

As for the 16.5 billion, the tycoon added, 'it is the bare minimum. The actual production will probably be several times higher,' he said in another post on the social networking site he owns. According to an analyst at NH Investment & Securities, Samsung's factory in Taylor "had virtually no customers so far, so this order is quite significant."

Competitive Recovery for Samsung

From an industrial point of view, therefore, the deal allows the Korean chaebol to catch up with its Taiwanese competitor TSMC, which now dominates the global market with a share of over 65%. The contract with Tesla, although representing a relatively small share of total revenues, guarantees stable volumes for eight years and can act as leverage to attract other global customers. The division's annual revenues could increase by up to 10 per cent.

Semiconductor Geopolitics

The agreement also fits into the well-known geopolitical context. Tensions between the United States and China, coupled with the fragility of the global chip supply chain, are pushing Washington to reduce its dependence on a risk area such as Taiwan. Samsung thus becomes a key player. The axis between the US and South Korea - already strengthened by agreements in the shipbuilding and battery sectors - now extends to high-end semiconductors.

The contract between Tesla and Samsung does not alone resolve the critical issues that both groups are facing, but it does represent a significant step in redefining the balance in the industry. For Samsung, it is an opportunity to relaunch itself as a credible third-party manufacturer of next-generation chips. For Tesla, it is a building block in its strategy of vertical integration and industrial autonomy. For the American system, it is a further step towards greater resilience of the technology supply chain, in a global context increasingly exposed to political and industrial risks.
