The Report
Bloomberg reported this week that Apple is actively evaluating Intel and Samsung Foundry as backup manufacturers for iPhone processors. The current arrangement: 100% of A-series and M-series chips fabricated by TSMC at their Taiwan and Arizona facilities.
If accurate, this is the most significant supply chain change in Apple's history. The 100% TSMC dependency has been a structural concern for years. The company has now taken concrete steps to address it.
Why TSMC Dependency Was Always the Risk
TSMC produces approximately 60% of all semiconductors made in the world. They produce nearly 100% of the most advanced chips — including every Apple silicon component shipped in iPhones, iPads, and Macs.
The company is headquartered in Taiwan. Approximately 90% of their advanced production capacity is also in Taiwan. China has been increasing military pressure on Taiwan for years. Defense analysts have repeatedly identified a Taiwan crisis as the single largest concentrated risk in the global tech supply chain.
Apple is more exposed to that risk than any other company on Earth. Their entire revenue base depends on TSMC continuing to operate without disruption. Diversifying that dependency has been a strategic priority that finally appears to be moving.
Why Intel Specifically
Intel's 18A and 14A process nodes are reportedly approaching competitive performance with TSMC's comparable nodes. Intel Foundry Services has been actively pursuing major customers and has won deals with Microsoft, Qualcomm, and several defense contractors.
Apple production at Intel's Arizona, Ohio, or Israel facilities would diversify geographic risk away from Taiwan and would benefit from US CHIPS Act subsidies. The political optics — bringing iPhone chip production fully to American soil — would also be enormous.
The challenge: Intel's yield rates are still behind TSMC. Apple cannot ship a product line of 250+ million units annually with chips that fail at higher rates than current parts. Intel has to prove production reliability before they get serious volume.
Why Samsung
Samsung Foundry produces chips for Qualcomm, AMD, and Samsung's own Exynos line. Their advanced nodes are roughly equivalent to Intel's but with different tradeoffs.
Samsung facilities are primarily in South Korea, with growing US capacity in Texas. South Korea is a US treaty ally with significant geopolitical risk of its own (North Korea), but it is a different basket of risk than Taiwan.
Apple has used Samsung in the past — early A-series chips were Samsung-fabricated. The relationship cooled when Samsung became a major iPhone competitor through their Galaxy line. Reviving it would mark a significant strategic shift.
The China-Taiwan Implication
The most important context for this story is what it implies about Apple's assessment of Taiwan risk. Apple has access to the best intelligence in the corporate world. They have invested decades into the TSMC partnership. They are not making this move casually.
If Apple believes the next 5-10 years carry meaningful Taiwan crisis risk, the best book to read on the broader semiconductor war is Chip War by Chris Miller. It is the definitive account of how the global semiconductor industry was built and why Taiwan became the chokepoint that everyone now scrambles to diversify around.
The Investor Translation
For Apple: gradual diversification reduces tail risk and increases supply chain resilience. Short-term: minor margin pressure as multiple foundries means less negotiating leverage. Long-term: dramatically reduced concentration risk.
For Intel: a contract win with Apple would be transformative. Intel Foundry Services has been the laughing stock of the tech industry for years. Landing Apple as a customer would validate the turnaround thesis and likely send INTC stock significantly higher.
For Samsung: strengthens their foundry business, validates the Texas facility investment, but also introduces complexity around competitive dynamics with Apple's iPhone business.
For TSMC: less revenue concentration risk but losing an irreplaceable customer. The implication for TSMC is gradual rather than acute. Apple is not abandoning them. They are diversifying around them.
What Comes Next
Apple has not confirmed the Bloomberg reporting. Confirmation may not come — Apple historically does not telegraph supply chain moves. Watch for:
1. Intel earnings calls for any unusual customer commentary
2. CHIPS Act funding announcements that include Apple-relevant facilities
3. Geographic shifts in Apple's product carbon footprint disclosures
The strategic shift, if real, will play out over years. The first iPhone with Intel-fabricated chips would not ship until 2027 or 2028 at the earliest. But the decision to begin that journey is the news.
