Intel shares rose 6% in premarket trading after Reuters reported that Taiwan Semiconductor Manufacturing, or TSMC, had approached US chip designers Nvidia, Advanced Micro Devices, and Broadcom about taking stakes in a joint venture that would operate the struggling chipmaker's factories.

Four sources told Reuters that the Taiwanese chipmaking giant would run Intel's foundry division under the new proposal, producing chips tailored to customer requirements but not owning more than 50%. The sources added that Qualcomm has also been approached about the venture. 

The sources noted that the Trump administration is exploring ways to revive Intel and strengthen US manufacturing under the 'America First' agenda. They added that TSMC's joint venture pitch to chip designers took place before the company, alongside President Trump, announced plans last month to invest $100 billion in semiconductor manufacturing in the US, building on its existing $65 billion investment in its Phoenix, Arizona, factories.
