These Were the Hottest S&P 500 Stocks of the Year
AI winners lead the list of the S&P 500's top 25 stocks of 2025, but some of the names might surprise you.
The top 25 stocks in the S&P 500 this year might be dominated by tech names taking off on the AI trade, but big-time market beaters can be found in the industrials and materials sectors, too.
First, a quick recap: A volatile spring sell-off (sparked by the "Liberation Day" tariff shock in April) couldn't stop the bull market from stampeding through 2025. Indeed, thanks to a strong outlook for corporate earnings and the continued frenzy over AI infrastructure spending, equities are set to end the year at record levels.
With just a few days left of 2025, the S&P 500 has delivered a price gain of nearly 18% year to date, with Magnificent 7 stalwarts such as Alphabet (GOOGL) and Nvidia (NVDA) backstopping the cap-weighted benchmark's returns.

It should come as no surprise, then, that the information technology and communication services sectors were the primary outperformers this year, rising 26% and 22%, respectively. The industrials sector, up 19%, also managed to beat the broader market.
A closer look at the individual names in the S&P 500 reveals that 12 of the 25 hottest stocks of 2025 were tech-related. However, the rally has broadened significantly; five of the best-performing equities hail from the industrial stock sector, while financial stocks, materials stocks, health care stocks, utility stocks, consumer discretionary and consumer staples are all represented, too.

What the hottest stocks of 2025 tell us
An interesting takeaway from this list is that the biggest beneficiaries of the AI trade weren't the hyperscalers. Instead, it was a collection of tech companies that design and manufacture the computer memory and storage products that live inside servers.
The ongoing build-out of AI data centers isn't just creating massive demand for specialized chips; it's also fueling a run on flash memory and high-capacity hard disk drives. That's why shares in SanDisk (SNDK), Western Digital (WDC) and Micron Technology (MU) posted the market's most explosive gains this year.
For example, SanDisk is the S&P 500 leader for 2025 with nearly a sixfold price gain. The company, which specializes in flash storage, was spun off from Western Digital in February 2025 and subsequently added to the S&P 500 in November. Investors are bullish because higher-than-expected demand from AI data centers has allowed SNDK to raise prices and expand its profit margins.
The aforementioned Western Digital comes in second in price appreciation, as shares nearly quadrupled this year. By spinning off SanDisk to concentrate on its core competency in hard disk drives, the company became a "pure-play" favorite for investors. The market rewarded the move, viewing hard drives as a relatively stable, high-margin business compared to the more volatile and cyclical flash memory market.
Meanwhile, hyperscalers such as Amazon.com (AMZN), Alphabet (GOOGL) and Microsoft (MSFT) have a seemingly insatiable demand for WDC's high-capacity drives. As a pure-play hard drive manufacturer at the center of the AI boom, it's no wonder WDC had a fantastic year.
Which brings us to Micron Technology. One of the world's biggest memory chipmakers pivoted in 2025 to become a specialized provider for AI infrastructure. The market applauded rapturously, sending MU stock up almost 240%.
A company whose biggest customers include nearly every member of the Mag 7 – plus Advanced Micro Devices (AMD), among many others – is in an enviable position as an AI play. Like its peers, Micron enjoys significant pricing power due to overwhelming demand, allowing the company to post record-breaking revenue in its most recent quarter.
