Apple's first foldable phone sold out before most shoppers finished their morning coffee. Pre-orders for the iPhone Duo opened at 8 a.m. Eastern on Friday, and within minutes the company's online store began quoting delivery dates in the new year, a stunning iPhone Duo sellout that surprised even seasoned Apple watchers. The $1,999 device, which folds shut like a wallet and opens into a small tablet, exhausted its launch-day allocation so quickly that customers who had only waited a few minutes found themselves facing ship dates in late January of next year. In a statement, Apple described the pre-order demand as "nothing short of extraordinary" and said it is working to get the device into customers' hands as quickly as possible.

The Duo is the first iPhone with a folding display: a 5.4-inch outer screen that opens like a book onto a 7.6-inch inner panel, wrapped in a titanium frame and sold in two colors, Night Sky and Star White. Apple showed it off at a keynote last month, the first major hardware event under new chief executive John Ternus, who took over from Tim Cook earlier this year. Cook remains at the company as executive chairman. Two middle configurations sit between the entry price and the $3,199 top tier, which pairs the largest storage option with the same folding hardware, a pricing ladder that did nothing to slow the iPhone Duo sellout.

Pre-orders vanish in minutes

By midmorning, the iPhone Duo sellout had become the story. According to the New York Post, shoppers who hesitated for even a few minutes after sales began saw their delivery estimates jump from the planned in-store launch into the winter. Screenshots of order confirmations with January ship dates circulated on social media alongside complaints from customers who had set alarms to buy the moment pre-orders opened. The publication noted that launch-day pickup inventory, the stock Apple normally holds for walk-in and click-and-collect buyers, sold out as well.

A resale market appears overnight

Where the iPhone Duo sellout left empty shelves, eBay filled the gap. MacDailyNews reported that dozens of listings for confirmed pre-orders sold at steep premiums, including a top-tier Night Sky model that changed hands for $4,999.99, roughly $1,800 more than its retail price, and a one-terabyte model that sold for $4,400. With no physical devices in buyers' hands yet, nearly every listing is a pre-order transfer, which carries the usual risks of scams and platform fees that push the practical break-even well above retail. Active asking prices clustered between $2,800 and $3,750, with some listings higher still.

The resale rush is not new to Apple launches, but the scale of the markups suggests the Duo landed with unusual hype. Foldable phones remain a niche: IDC data cited by CNBC puts folding phones at just over two percent of global shipments and nearly seven percent of industry revenue, a high-margin corner of the market Apple watched Samsung and Google build alone for years before deciding to enter it. The iPhone Duo sellout suggests that patience paid off. CNBC quoted IDC analyst Nabila Popal, who noted that the technology itself is not new, since Android foldables have existed for years, but what is new is Apple bringing the form factor to its enormous base of existing users.

What Apple is betting on

For the company, the iPhone Duo sellout is the first real test of Ternus's leadership of its most important product. Yorkville analyst Dan Ives told CBS News he expects Apple to sell roughly ten million units in the coming quarters, a figure that would make the Duo one of the fastest-selling premium phones Apple has ever shipped. The new chief executive unveiled the phone at his first keynote last month, pairing the folding hardware with software that splits the screen to run two apps side by side, a layout closer to an iPad than to a standard phone. The pitch is that longtime iPhone owners who skipped recent upgrades will pay a premium for a form factor that feels genuinely new.

Whether the demand holds past the opening weekend is the open question. Apple said it will keep accepting online orders, and stores are expected to get fresh stock with the in-store launch next week, which could cool the resale market quickly. The iPhone Duo sellout has already made one thing clear: for Apple's most eager customers, the price of folding glass was never the obstacle.
