October 18, 2026 — On the evening of October 16, Apple opened pre-orders for the iPhone Duo. What happened next was unlike anything seen in recent years: Apple's official website crashed, e-commerce platforms sold out in seconds, and resale prices on the secondary market spiked by thousands of yuan.

This was not just a successful product launch. It was a market signal that validated a shift Apple made weeks ago — and it tells us exactly who is buying the foldable, and who is being left behind.

iPhone Duo Pre-orders: The "Crazy Data" of One Night

The scale of the pre-order event was unprecedented for a non-standard iPhone release.

• The servers crashed: Apple customer service stated that the traffic during the Duo pre-order exceeded the volume seen during the iPhone 18 Pro series launch.
• One-minute sellout: Major platforms like JD.com and Tmall saw all models and storage configurations sell out within 60 seconds.
• The reseller frenzy: On secondary markets like Xianyu, listings appeared instantly with premiums of RMB 6,000 to 10,000 above retail price. Some sellers offered "proxy buying" services for a fee of RMB 299 to 1,000.

By the end of the week, reports indicated that Apple's smartphone sales share in the Chinese market had surged past 37% — a remarkably high figure driven almost entirely by the Duo's launch momentum.

Validation: Our Prediction from 10 Days Ago

This outcome did not happen by accident. It is the direct result of a supply chain adjustment Apple made weeks ago.

On October 12, we reported that Apple had structurally adjusted its fall order book: iPhone Duo orders were increased by 30%, iPhone 18 Pro orders were cut by 10–15%, and Pro Max orders were increased by 10–15%. The total volume for the Pro series remained unchanged.

At the time, the analysis was that Apple was shifting production toward higher-value products to offset rising memory costs. The standard Pro model was being squeezed from both sides: users who wanted the ultimate slab experience bought the Pro Max, while users who wanted to show off new technology bought the Duo.

The pre-order data has proven this logic to be exactly right. The massive demand for the Duo has completely absorbed the budget that would have gone to high-end Pro users. The standard Pro is no longer the default choice for "I want the best iPhone" — the Duo and Pro Max have taken that role.

What 37% Market Share Actually Means

Seeing "37% market share" sounds impressive, but it is important to understand the structural shift behind the number.

Furthermore, this proves that foldables are no longer a niche. For years, Android manufacturers struggled to make foldables mainstream. Apple's entry proves that if the ecosystem and brand power are strong enough, high-end users are willing to pay a premium for the folding form factor.

Is the 6,000-10,000 RMB Premium Reasonable?

For consumers, the most important question is whether to pay the reseller premium. The short answer is: absolutely not.

The Hidden Risk: Yield and Supply Chain

While the demand is a massive win for Apple, the supply chain is under extreme pressure. The 30% order increase is a heavy burden on manufacturing.

As we noted previously, the initial manufacturing yield for the iPhone Duo was reported to be around 60% to 65%, with the complex hinge and flexible display being the primary bottlenecks. The fact that the servers crashed and stock sold out instantly shows that Apple simply did not have enough units ready for the initial wave.

If production cannot ramp up quickly, or if the early units suffer from quality control issues due to the rushed production, the excitement could quickly turn into frustration. Apple needs to ensure that the phones arriving in users' hands in late October and November meet the premium expectations set by that RMB 15,999 price tag.
