Cook steps down, Apple gets a new CEO: Behind OpenAI's bulk purchase of Mac minis lies Apple's ticket to the new AI era
- Core takeaway: Apple's CEO transition to hardware chief Ternus signals a strategic shift from an operations-driven era to a product innovation era, with the core competitive focus being the establishment of a new advantage in AI hardware built on its unified memory chip architecture.
- Key factors:
- OpenAI has purchased tens of thousands of Mac minis and Mac Studios for AI agent training, while Anthropic has massively rented Mac computing power through AWS, validating the commercial value of Apple silicon in AI inference scenarios.
- Apple's unified memory architecture can directly load models with hundreds of billions of parameters, reducing data movement between VRAM and system memory compared to Nvidia GPUs, significantly lowering the cost of running large models.
- Mac revenue grew 29% year-over-year to $10.3 billion in the latest quarter, making it Apple's fastest-growing hardware line, with enterprise AI demand directly boosting performance.
- Nvidia regards Apple as its biggest competitor in the local AI market, and its DGX Spark product resembles the Mac mini in form factor, which indirectly confirms Apple's threat in the AI hardware space.
- Ternus-led fall product pipeline includes a foldable iPhone and a smart display device capable of recognizing speakers, seen as key moves in Apple's AI hardware strategy.
- Cook remains as executive chairman, ensuring a smooth transition of power with limited short-term stock impact; over the next 3–5 years, Apple's valuation growth will depend on the actual performance of the "AI + chips + new hardware entry points" combination.
On September 1, Apple marked a highly momentous day: Tim Cook's 15-year tenure as CEO officially came to an end, with hardware chief John Ternus taking over the reins the same day.
In this era of AI frenzy, the core challenge Ternus faces after taking office is hardly a surprise — how to lead this consumer electronics giant built on hardware to re-establish its competitive edge in the age of AI.
1. Apple's Lukewarm Stance Suddenly Gets a Boost from OpenAI
Throughout this wave of AI, Apple's performance has been steady but unremarkable — not exactly falling behind, yet far from being a protagonist.
However, a newly revealed piece of news may hand Apple a ticket back to the AI table: OpenAI has already purchased tens of thousands of screenless, keyboardless Mac mini and Mac Studio machines for reinforcement learning training and the development of "computer-use" AI agents; Anthropic has also been renting Mac computing power on a large scale via AWS.
Why are AI companies flocking to Mac? The answer lies in Apple's chip architecture. Apple silicon adopts a unified memory architecture that can directly load quantized models with tens of billions or even over a hundred billion parameters — no need to shuttle data back and forth between VRAM and system memory like Nvidia GPUs. For those running large models, this saves not just time, but also hard cash on costs.
2. The Financials Already Show It: Mac Becomes Apple's Fastest-Growing Hardware
The influx of enterprise demand has been directly reflected in the financial statements. Mac's latest quarterly revenue grew nearly 29% year-over-year to $10.3 billion, making it Apple's fastest-growing hardware product line.
An even more compelling signal comes from a competitor: Nvidia has internally identified Apple as its biggest rival in the on-device AI market. Nvidia's previously launched DGX Spark even resembles the Mac mini in form factor — being "honored" with a tribute by Nvidia is itself a form of status recognition.
3. The New Chief Ternus: A Product-Focused Leader Who Rose from Mac Engineer
So, at this critical juncture, who exactly is Apple's new successor, Ternus? Ternus has actually been at Apple for 25 years, starting as a Mac engineer and working his way up to lead iPad, AirPods, and iPhone development, eventually overseeing the entire hardware engineering system — widely recognized as Apple's in-house hardware expert.
The tests have already lined up from day one: the September iPhone launch event and the full-scale rollout of the new Siri AI.
And the new product pipeline he oversees is nothing short of ambitious: this fall, Apple is set to release a foldable iPhone and a smart display device capable of recognizing speakers and delivering personalized content accordingly. Whether these products deliver on their promises will directly determine whether Apple can hold its ground in the AI hardware arena.
4. The Subtext from the Board: Apple's Gap Isn't Money, It's the Next Product Innovation
Looking back at this leadership transition, the choice itself sends a message.
Over the past decade-plus, Apple's strengths have been operations, supply chain, ecosystem, and profitability. But in the AI era, what Apple truly lacks is neither money nor users — it's "the next product innovation." That's why the board didn't pick a finance-focused CEO, but instead handed the reins to a product-driven leader with a mechanical engineering background and 25 years of deep hardware expertise.
In the short term, the CEO change will have limited impact on the stock price, since Cook will remain as executive chairman, so there will be no power vacuum at Apple. What truly determines Apple's future valuation isn't whether the next iPhone sells a few million more units — it's whether Apple can find a new gateway in the AI era. Over the next 3 to 5 years, Apple's biggest bet may no longer be the iPhone, but rather the combination of "AI + chips + new hardware gateways."
5. Final Thoughts
Fifteen years ago, Cook took over Apple from Jobs and drove the company to the pinnacle of global market value with operations and supply chain expertise. Fifteen years later, the board has handed the baton to a hardware engineer — a public acknowledgment that the dividends of the "operations era" have run their course, and Apple must return to the "product innovation era."
The signals — OpenAI stockpiling Mac minis, Nvidia naming Apple its top on-device AI rival — suggest that Apple has actually been holding a ticket to the AI era all along: chips with unified memory architecture. What it lacked was the product vision to put that ticket to use.
Whether Ternus can bridge that gap will become apparent at the fall launch event, and the next three to five years will continue to reveal the truth.
