Intel just had the kind of day most companies dream about. Shares of the chipmaker surged between 10% and 19% on May 8, 2026, after reports surfaced that Intel Foundry had reached a preliminary agreement to manufacture processors for Apple devices.

The rally wasn’t contained to a single ticker. Intel’s explosive move helped push both the S&P 500 and Nasdaq to fresh record highs, with robust earnings from AI chip makers providing additional fuel for the broader market’s climb.

The deal that changed everything (maybe)

This isn’t a done deal in the traditional sense. The agreement between Intel and Apple reportedly followed more than a year of negotiations, and there are no specifics yet on which chip types will be manufactured, what volumes are expected, or when production might actually begin. Pre-2027 shipments appear unlikely based on the current timeline.

The motivation on Apple’s side is straightforward. The company has been looking to diversify its chip supply chain away from heavy reliance on TSMC, the Taiwanese semiconductor giant that fabricates the vast majority of the world’s most advanced chips. Ongoing chip shortages have made single-source dependency increasingly uncomfortable for a company that ships hundreds of millions of devices annually.

Both Bloomberg and Reuters have previously reported on Apple exploring manufacturing options with Intel and Samsung as potential alternatives to TSMC. This preliminary agreement suggests those explorations have progressed beyond the tire-kicking phase.

Intel’s foundry bet gets its biggest endorsement

For Intel, landing Apple as a foundry client would be the crown jewel in a turnaround strategy that has been equal parts ambitious and questioned. The company has been aggressively courting major technology firms to use its manufacturing capabilities, with existing foundry clients reportedly including Microsoft, Amazon, Tesla, and the US Government.

Intel’s foundry division is projected to reach break-even by 2027. Adding Apple to the client roster makes that target look considerably more achievable.

Intel spent years watching its manufacturing edge erode while TSMC and Samsung pulled ahead. Under CEO Pat Gelsinger’s ‘IDM 2.0’ strategy initiated in 2021, Intel aimed to attract external clients to compensate for over $7 billion in lost foundry revenue by 2025.

The broader market context amplified Intel’s impact. Strong earnings reports from companies in the AI chip sector created a tailwind that was already pushing indices higher, contributing to record highs in both the S&P 500 and Nasdaq.

What this means for investors

The Intel-Apple agreement is preliminary. No chip types have been specified. No volumes have been committed. No timelines have been set.

The semiconductor supply chain diversification trend is real and durable regardless of this specific deal’s outcome. Apple’s willingness to explore alternatives to TSMC reflects a structural shift that benefits any company with advanced fabrication capabilities. Intel, Samsung, and emerging players in the foundry space all stand to gain as major tech companies reduce concentration risk.
