This report analyzes five market trends that will shape the fourth quarter of 2026 and demonstrates that weekly sales data by brand is the only indicator capable of accurately identifying these trends. From the fierce annual battle for the top spot between Samsung and Apple to Apple's launch of its first foldable phone, and Samsung's price hike on an older model just seven months after its release, the direction of all these stories will be determined on a weekly basis, not a quarterly one.
