Apple and Intel have reportedly reached a preliminary agreement that would see Intel produce some chips for Apple devices.

If completed, the deal would be the most notable vote of confidence yet for Intel’s once-struggling chip foundry business.

Apple currently relies on Taiwan Semiconductor to build all the most advanced chips for its devices.

Apple and Intel are reportedly closing in on a deal that would see Intel produce some of the chips for the iPhone maker’s devices, marking a major shift in the chipmaking landscape.

Talks between the two companies have been brewing for more than a year, with a preliminary agreement reached in recent months, the Wall Street Journal reported Friday, citing the public familiar with the matter.

Intel shares soared nearly 14% on Friday. Apple shares added 2%. Both companies declined to comment. This also touches on aspects of bull market.

“I 100% believe this is going to happen. I don’t know when,” chip analyst Ben Bajarin of Creative Strategies stated in an interview.

If it comes to fruition, the deal would be the most notable vote of confidence yet for Intel’s once-struggling chip foundry business. Intel shares are up more than 200% this year.

For Apple, it would be the end of era. The iPhone maker currently relies solely on Taiwan Semiconductor Manufacturing Co. to generate all the most advanced chips for its devices.

But TSMC’s wafer capacity can only go so far, amid soaring demand for AI chips that has sent every major tech enterprise into a semiconductor frenzy. Apple is no exception, ramping up its in-house silicon program in recent years to construct nearly all the core chips in iPhones, Macs and more. Apple is TSMC’s second-largest customer, topped only by Nvidia, according to Bajarin.

“Intel is the only place that can scale up capacity as a viable second source,” Bajarin commented.

Intel is indeed ramping up capacity quickly, with a latest chip fabrication plant now in high-volume production in Chandler, Arizona. It’s making chips there on 18A, its most advanced node, or production process, which is meant to rival TSMC’s 2nm node that’s currently only manufactured in Taiwan. TSMC also has multiple novel chip fabs in Arizona, where Apple has committed to making some of its silicon.

Bajarin mentioned Apple is most likely to wait to construct chips on Intel’s next node, called 18A-P, which could scale as soon as next year. He called Intel’s current 18A node “a little bit rough” and stated 18A-P “cleans a lot of stuff up.”

For years, Intel’s foundry business faced delays and low yields that cast doubt on its ability to manufacture chips for others. For now, Intel remains the only major customer of its foundry business, making central processing units and other chips for its own devices.

Bajarin stated those days are over.

“They’ve got through the rough patch and can now be considered validated as a credible second source,” he remarked.

Intel’s only other major external customer commitment for foundry is unlikely to see real results until 2029 or beyond.

Elon Musk commented last month that he plans to rely on Intel’s future 14A chip node at his $119 billion Terafab planned for Austin, Texas, which is meant to create chips for Tesla, SpaceX and SpaceXAI. Intel CEO Lip-Bu Tan remarked in February that 14A will be in volume production in 2029.

Intel already has major customers — such as Amazon and Cisco — for the advanced packaging side of its chipmaking business, in which individual chip dies and memory are bonded together to construct things like a graphics processing unit.

An Apple-Intel deal won’t impact TSMC because “they’re already printing wafers as fast as they can,” Bajarin commented. Still, TSMC shifted its rhetoric last month when President and CEO C.C. Wei called Intel a “formidable competitor.”

“If you’re about to have one of your largest customers probably sign a deal with a competing foundry, that would be the kind of thing you say to perhaps soften the blow,” Bajarin remarked.

Apple executives have also reportedly visited Samsung’s updated chip manufacturing plant under construction in Texas, where CNBC got an early look. Samsung, Intel and TSMC are the only three companies in the globe capable of manufacturing the most advanced chips needed for AI, and “nobody can build fast enough,” Bajarin commented.
