IDC: Apple closes in on Samsung as global smartphone shipments see record decline in Q3

Global smartphone shipments fell 22% year over year in Q3 2026, according to IDC’s preliminary data. The decline marked a record downturn for the industry. It reflects pressure from a memory shortage and sharply higher component costs. Lower-priced phone makers were especially affected.

Samsung remained the market leader, shipping 57.8 million smartphones. Its shipments fell 5.8% from the same quarter in 2025, leaving it with a 22.6% worldwide share. Apple ranked second with 57.3 million shipments. The difference between the companies was only 500,000 units, or 0.2 percentage points in share.

Apple’s shipments still declined, but only 4% year over year. Because that drop was much smaller than the overall market decline, Apple’s relative share increased 23.1%. IDC warned that conditions could worsen before recovery, with memory costs still elevated and other component expenses adding pressure.

Smartphone market share is the percentage of total smartphone shipments credited to one company. It shows how large a brand’s shipment presence is compared with its competitors. A company can therefore lose shipments while gaining share if the overall market, or rival shipments, falls more sharply.

Apple provides a clear example. Its iPhone shipments declined 4% year over year in Q3 2026. IDC reported that global smartphone shipments fell 22%. Since Apple’s decline was much smaller than the market’s decline, Apple represented a larger portion of the remaining shipments. Its share increased 23.1% compared with the year-ago period.

The same pattern appears in Apple’s race with Samsung. Samsung shipped 57.8 million phones, compared with Apple’s 57.3 million, but Samsung’s shipments dropped 5.8%. Apple was therefore only 500,000 units behind and narrowed the shipment-share gap to 0.2 percentage points.

IDC’s preliminary figures show global smartphone shipments dropped 22% in Q3 2026 compared with Q3 2025. The report describes this as a record decline for the industry. The fall is important because it affected the worldwide market, not just one country or region. IDC linked the downturn to the ongoing memory shortage and rising component costs.

Samsung shipped 57.8 million smartphones and held a 22.6% worldwide shipment share. Apple shipped 57.3 million units. That left Samsung ahead by just 500,000 phones. The companies’ shipment shares differed by only 0.2 percentage points, making the top of the ranking unusually close during a sharply shrinking market.

Apple’s 4% year-over-year decline was the smallest among the top five brands listed. Samsung fell 5.8%, while OPPO recorded a much steeper 34.5% drop. IDC also warned that the market may not yet have reached its bottom.

The main cause identified in the report is an ongoing shortage of memory components. That shortage has sent component costs soaring. Smartphone makers must manage those higher costs while trying to keep devices competitive. The pressure is especially strong for companies focused on lower-end markets, where there is less room to absorb expensive parts.

IDC said memory costs had surged approximately 350% since the previous year. Costs for other critical components also remained elevated. The combination created what IDC described as a substantial squeeze on vendor margins and shipments. The resulting pressure contributed to the industry’s 22% year-over-year shipment decline in Q3 2026.

Memory inflation was beginning to slow, but costs were still rising. IDC reported a low double-digit sequential increase in Q3, compared with roughly 50% to 100% growth in earlier quarters. It warned that the market had not yet reached its bottom.

Apple’s shipments declined less than those of the other leading brands because its 4% drop was smaller than the market’s 22% contraction. That relative resilience allowed Apple to increase its worldwide shipment share by 23.1%. It also brought Apple within 500,000 units of Samsung, despite Samsung remaining number one.

The report gives OPPO’s result clearly: its shipments fell 34.5% year over year, the largest decline among the top five companies. Samsung declined 5.8%. The article names Xiaomi and vivo among the remaining leaders but does not provide their shipment declines. It also does not identify a specific product or strategy that explains Apple’s result.

What the report does establish is the broader mechanism. Rising memory and component costs squeezed vendors, especially in lower-end markets. Apple’s smaller decline shows it was less affected than the listed rivals, but the article does not prove why. IDC still expects conditions to worsen before they improve.

Rising memory and component costs make each smartphone more expensive to build. Manufacturers then face a difficult choice. They can absorb the extra expense, reduce their profit margin, raise prices, or produce fewer devices. The article specifically reports pressure on vendor margins and shipments, but it does not report actual retail price changes.

The scale of the pressure was substantial. IDC said memory costs had increased approximately 350% since the previous year. Other critical component costs also remained elevated. For lower-end manufacturers, these increases are especially difficult because their products compete in price-sensitive markets. Higher costs can therefore weaken profitability and make production plans harder to sustain.

Memory inflation was slowing, but it had not stopped. Costs rose at a low double-digit sequential rate in Q3, compared with roughly 50% to 100% in earlier quarters. IDC said the market had not reached its bottom, suggesting continued risks for margins, prices, and shipment volumes.

Semiconductor memory is a group of electronic chips that store information in digital form. Smartphones use working memory to hold data temporarily while apps and systems operate. They also use nonvolatile memory to retain software, photos, messages, and other files when the phone is turned off. The source article does not define these memory types; this explanation uses established technical knowledge.

Memory is essential because a smartphone must both run its operating system and store user content. If memory components are unavailable, manufacturers may be unable to complete as many devices. If the parts become expensive, the cost of building each phone rises. These effects connect memory supply directly to production and profitability.

IDC reported that memory costs surged approximately 350% from the previous year. It said the shortage squeezed manufacturers, particularly those serving lower-end markets. Memory inflation had begun slowing, but costs remained elevated, and IDC warned that the smartphone market might decline further before recovering.
