Semiconductor and memory chip manufacturers saw massive share price surges in the first half of 2026 as AI-driven hardware demand outpaced supply. Major players like SK Hynix and Sandisk recorded triple-digit gains, while investors shifted capital away from large software companies and hyperscalers like Microsoft.
Why are chip stocks outperforming software companies?
Investors are rotating capital out of software and into the hardware that powers artificial intelligence. This shift has left many “hyperscalers”—the large companies rolling out AI services—struggling to maintain their valuations. For example, Microsoft’s share price fell 24% during 2026, hitting a one-year low last week.
The movement suggests a change in investor sentiment regarding the cost of AI implementation. Some investors are expressing concern over the massive spending plans announced by leading AI firms. According to market analysis, these heavy investments require higher borrowing, which increases capital intensity and could eventually impact corporate cashflow.
When investors move from software to hardware, they are often betting on the “picks and shovels” of a new industry—the essential components required to build the technology, rather than the end-user applications.
How much have semiconductor shares grown in 2026?
The growth in the semiconductor sector has been described by Dan Coatsworth, head of markets at AJ Bell, as “the kind of gains in six months you might normally expect over decades.” This surge is largely attributed to a combination of high demand and constrained supply, which has driven up memory chip prices.

Data from the London Stock Exchange Group highlights the scale of this movement, particularly in the Asia Pacific region. South Korea’s Kospi index rose 125% this year, marking its strongest first half since at least 1990. This performance was fueled by two major electronics groups:
- SK Hynix: Share price rose 310% since the start of January.
- Samsung: Share price increased 183% so far this year.
U.S.-based chipmakers have seen even more extreme volatility and growth. According to recent analysis, Sandisk shares rose 780% in 2026, following a 4,510% increase over the last 12 months. Other significant U.S. performers include Micron, up 296%, and Western Digital, which gained 240% this year.
| Company | 2026 YTD Gain (Approx.) |
|---|---|
| Sandisk | 780% |
| SK Hynix | 310% |
| Micron | 296% |
| Western Digital | 240% |
What is the impact of rising chip costs on consumer electronics?
The surge in demand for AI-capable hardware is directly affecting the cost of consumer goods. Apple recently attributed a rise in iPad and MacBook prices to the increasing cost of memory chips. This demonstrates how the semiconductor boom moves beyond the stock market and into the pockets of everyday consumers.
Geopolitical tensions are also complicating the supply chain. Apple is reportedly seeking clearance from the Trump administration to purchase memory chips from CXMT, a Chinese firm currently blacklisted by the Pentagon. This highlights the friction between the urgent need for hardware and international trade restrictions.
The Kospi index’s 125% jump is its most significant first-half performance in over three decades, driven almost entirely by the electronics sector.
Will the AI-driven market rally continue?
While the first half of the year has been bullish, some analysts suggest the momentum may be hitting a ceiling. Chris Beauchamp, chief market analyst at IG, noted that investors who entered the market in late March are now looking to protect their profits. He described the current mood as one where investors “sell first and ask questions later.”
Despite this caution, some institutional analysts remain optimistic about the broader U.S. market. Mark Haefele, chief investment officer at UBS Global Wealth Management, predicts the S&P 500 could reach 8,200 points by June 2027. Haefele cites continued strength in AI capital expenditure and a resilient U.S. economy as the primary drivers for this projected growth.
Global Market Snapshot
The semiconductor boom hasn’t been the only story in global finance this year. While tech has dominated, other sectors have seen notable movement:

- Japan: The Nikkei climbed 38% in the first half of the year.
- United Kingdom: The FTSE 100 gained 5.8%, supported by various takeover offers.
- Commodities: Brent crude oil ended June approximately $12 higher than its January start, following a spike to over $120 in April due to supply concerns in the strait of Hormuz.
Frequently Asked Questions
Why are chip stocks rising so quickly?
Demand for chips to power AI datacenters is currently exceeding the available supply, leading to higher selling prices and explosive earnings growth for manufacturers.
How is AI affecting consumer prices?
Increased demand for memory chips has raised manufacturing costs, which companies like Apple have passed on to consumers through higher prices for devices like MacBooks and iPads.
Is the tech boom slowing down?
Some analysts report that investors are beginning to rotate out of tech and into other sectors to protect the profits they gained during the initial AI surge.
