Apple's first foldable phone, the iPhone Duo, is in short supply after its launch. Apple has reportedly asked its supply chain to accelerate production and increase orders by 30%, which is beneficial for core suppliers such as Foxconn, TSMC, and Shin-Etsu Chemical. All iPhone Duo models sold out on its launch day, October 23, with the second wave of shipments expected to be delayed until January 22, 2027. On the secondary market, scalper prices once reached $3,068, a premium of about 33% over the lowest entry price of $2,300. Impacted by this, market research firms have revised this year's inventory forecast upwards to 8 million to 10 million units, with 2027 shipments projected to reach 33 million units. Industry experts expect the iPhone Duo to capture about 40% of the global foldable phone market next year.
