Summary of Key Points
The World Semiconductor Trade Statistics Organization (WSTS) has significantly raised its forecast for the global semiconductor market growth rate in 2026 from 26.3% to 89.9%, primarily driven by the soaring demand in the memory sector (expected to grow by 249.5%). However, the author believes that the 26.6% growth forecast for 2027 may be overly optimistic, as the extreme price increases in the memory market are unlikely to sustain, and there is even a possibility of negative growth in 2027, which could drag down the overall market.
1. The Memory Market Soars by 249%: Not Due to Higher Sales Volume, but Exorbitant Price Increases
The memory market (such as DRAM and NAND flash memory) has been the main driver of this growth, with a forecasted increase of 249.5% in 2026, more than six times the previous estimate of 39.4%. Why such a sharp rise?
- It's Not About Higher Shipments, but Exponential Price Increases: The actual number of chips sold for both DRAM and NAND has not increased significantly; instead, prices have skyrocketed. For example, DRAM faced shortages since September 2025, with sales increasing by 359% year-on-year in April 2026. NAND prices surged due to the sudden demand for high-speed SSDs (with SK Hynix launching new products), but supply could not keep up.
- Differences Between DRAM and NAND: The three major DRAM manufacturers (Samsung, SK Hynix, Micron) have invested record amounts in capacity expansion, which may ease supply-demand imbalances by 2026. For NAND, however, since manufacturers prioritized DRAM production, the development of high-speed products is lagging, and supply-demand balance is not expected until the second half of 2027.
- Concerns: These price increases are largely speculative; many companies have stockpiled goods in anticipation of further price hikes (creating artificial demand). Once supply and demand stabilize, these hoarders will likely stop buying, leading to a potential price crash. The author predicts that DRAM prices will cool down in 2027, while NAND prices may stabilize by 2028.
2. Performance of Other Semiconductor Segments Varies
Apart from the memory market, other segments have shown mixed results:
- Discrete Devices (e.g., Power Transistors): Forecasted growth of 8.9% (a slight upward revision), but the price of power transistors (IGBTs and MOSFETs) has been declining, which could result in weaker growth if prices continue to fall.
- Optical Semiconductors (e.g., Image Sensors): Forecasted growth of 2.7% (downward revision) due to the impact of rising memory costs on smartphone production, leading to decreased demand for image sensors (with the first negative growth in April 2026).
- Analog ICs: Forecasted growth of 10.2% (upward revision); ADI's price increases drove market growth, with actual sales increasing by 15.4% from January to April. The author believes the forecast is conservative and expects growth to be closer to 10% in 2027.
- Microprocessors: Forecasted growth of 19.8% (upward revision), supported by demand for servers (MPUs) and automotive applications (MCUs). Actual sales from January to April were 20.6%, and the market is expected to maintain around 20% growth in 2027 if data center demand remains stable.
- Logic ICs: Forecasted growth of 37.3% (upward revision), largely driven by NVIDIA's AI GPUs, which account for over 70% of the logic IC market. With over $1 trillion in unsold orders, the author expects a growth rate of over 40% in 2026 and a more modest 27.1% forecast for 2027.
3. The Reason for the Revised 2026 Forecast: Real Data Drives the Change
Why did WSTS raise its forecast from 26.3% to 89.9%? Actual market data was much stronger than expected:
- As of April 2026, semiconductor shipments had increased by 87.1% year-on-year, approaching the new forecast of 89.9%, making the revision inevitable.
- The memory market contributed the largest portion to overall growth, and combined with positive trends in other segments, the overall forecast was raised accordingly.
4. Divergent Views on 2027 Growth
While WSTS predicts a 26.6% increase for 2027, the author disagrees:
- Memory as a Critical Factor: If the memory market experiences negative growth (as predicted), it will significantly dampen overall market performance. Given the large contribution of memory to total sales in 2026, any decline in this segment would have a significant impact on the entire market.
- Risks: The extreme price increases in DRAM are abnormal and cannot persist indefinitely. Any improvement in supply-demand conditions will lead to a contraction in artificial demand and a sharp drop in prices, potentially causing a dramatic slowdown in the memory market.
- Author's Conclusion: The author believes that overall semiconductor market growth in 2027 could be very low or even negative, although few are willing to admit this possibility at present.
5. The Risks of Over-reliance on the Memory Market
The current growth of the semiconductor industry is heavily dependent on the memory sector, similar to a building supported by a single pillar:
- If the memory market cools down, the entire industry will be affected. For example, despite a 249% increase in 2026, a negative growth in 2027 would have a detrimental impact.
- Although other segments may grow, their scale and growth rates are far lower than those of the memory market, making it difficult for them to compensate for any decline in the memory sector.
In summary, the semiconductor market will benefit from the surging demand for memory in 2026, but 2027 poses significant uncertainties. Consumers may not notice these changes, but companies (especially those that purchase semiconductors) face a dilemma: stockpiling now could lead to losses, while avoiding purchases may result in shortages. The industry's over-reliance on memory-driven growth is unsustainable and could lead to long-term issues.
