On 28 July, Samsung Electronics announced in a filing submitted to regulatory authorities that it had signed a chip manufacturing agreement worth 22.8 trillion won (approximately 118.172 billion yuan or 16.5 billion US dollars at current exchange rates) with a global major company, but did not disclose the specific client's name.

According to sources from Reuters and Bloomberg, Tesla is the client in question, and the company already has existing business ties with Samsung's contract chip manufacturing division.

Bloomberg reported that Samsung Electronics will produce semiconductors for Tesla under the newly reached 16.5 billion USD agreement, which is expected to provide a boost to its underperforming wafer foundry division. 

The contract period for this collaboration runs from 24 July 2025 to 31 December 2033.

In response, Tesla CEO Elon Musk confirmed the collaboration, stating that Samsung's newly constructed massive factory in Texas will be dedicated to producing Tesla's next-generation AI6 chips (note: Tesla's autonomous driving chips), and remarked, ‘Its strategic importance is undeniable.’

Musk also mentioned that Samsung is currently producing AI4 chips. TSMC will first produce the newly designed AI5 chips in Taiwan, followed by production in Arizona, United States.

According to a report by The Motley Fool in June this year, TSMC holds a 67% market share in the global third-party wafer foundry market, while Samsung, ranked second, accounts for only 11%.

A source from BusinessKorea reported that Samsung Electronics' foundry division received no bonuses in the first half of 2025.

South Korean media outlet Chosu cited supply chain sources on 22 July, reporting that Samsung has launched a ‘select and focus’ strategy, concentrating resources to improve the yield rate of its 2nm process, aiming to challenge TSMC through production volume and cost advantages.
