As we move through 2025, the stock market continues to reward companies positioned at the intersection of technological innovation and essential infrastructure. While headline-grabbing names like NVIDIA and Microsoft have delivered solid returns, some lesser-known players have crushed the market with triple-digit gains.

This analysis focuses on the standout performers among S&P 500 companies with market capitalizations exceeding $10 billion. These aren’t speculative penny stocks or volatile small-caps – they’re substantial businesses that have managed to capture investor imagination while delivering real operational results. From artificial intelligence enablers to energy infrastructure plays, the top performers tell a fascinating story about where smart money is flowing in the evolving market landscape of 2025.

How These Top Performing Stocks Were Chosen

The methodology for identifying these market leaders is straightforward but selective. I screened all S&P 500 constituents with market capitalizations above $10 billion as of July 2025, then ranked them by year-to-date percentage returns. This market capitalization threshold ensures that we’re examining established companies with meaningful institutional ownership and trading liquidity, rather than smaller, speculative plays.

The $10 billion cutoff eliminates the volatility often associated with smaller companies while focusing on businesses large enough to impact portfolios and broader market indices meaningfully. These companies have demonstrated their staying power and represent sectors that institutional investors consider to have sustainable competitive advantages in today’s rapidly evolving economic environment.

The 5 Best Performing Stocks of 2025 So Far

1. Palantir Technologies (PLTR)

Why Palantir Technologies Is A Top Performer

Palantir’s stunning 113% gain represents the single best performance among large-cap S&P 500 stocks in 2025. The data analytics and software company has successfully transitioned from a government-focused contractor to a diversified enterprise software provider, with commercial revenue growing at an explosive pace. The company’s Foundry platform has gained significant traction among Fortune 500 companies seeking to harness artificial intelligence for operational efficiency.

What sets Palantir apart is its unique positioning in the AI value chain. Rather than competing directly with model developers like OpenAI, Palantir focuses on implementation and deployment, helping organizations utilize AI to solve real business problems. This practical approach has resonated strongly with enterprise customers who need more than just access to large language models.

The company’s government contracts continue providing stability, while commercial expansion drives growth acceleration. With a market cap now approaching $56 billion, Palantir has evolved from a niche defense contractor into a legitimate enterprise software powerhouse, justifying investor enthusiasm despite the stock’s remarkable run.

2. GE Vernova (GEV)

Why GE Vernova Is A Top Performer

GE Vernova’s 90% surge reflects the market’s recognition of the critical role energy infrastructure plays in supporting AI and data center expansion. As the spun-off energy division of General Electric, Vernova combines traditional power generation expertise with cutting-edge grid modernization and renewable energy solutions. The company benefits from massive infrastructure spending driven by AI’s voracious energy appetite.

Data centers supporting artificial intelligence workloads consume exponentially more electricity than traditional computing facilities, creating unprecedented demand for reliable power generation and distribution equipment. Vernova’s portfolio encompasses gas turbines, wind turbines, grid solutions and energy storage, positioning it as a comprehensive infrastructure partner for utilities and large technology companies.

The company’s backlog continues growing as utilities rush to upgrade aging infrastructure while adding capacity for AI-driven demand. With governments worldwide prioritizing grid resilience and clean energy transitions, Vernova sits at the center of multiple powerful secular trends that should support growth well beyond 2025.

3. NRG Energy (NRG)

Why NRG Energy Is A Top Performer

NRG Energy’s 78% gain demonstrates how traditional utilities can thrive in the new energy landscape. The Texas-based power generator and retailer has benefited from favorable commodity pricing, extreme weather events that boost electricity demand, and strategic positioning in high-growth markets. The company’s integrated model – owning generation assets while selling directly to consumers – provides natural hedging against market volatility.

Texas continues experiencing rapid population and economic growth, driving consistent demand increases for NRG’s services. The state’s deregulated electricity market allows NRG to capture value both as a generator and retailer, creating multiple revenue streams that traditional regulated utilities cannot access. Additionally, the company has made strategic investments in battery storage and renewable generation to complement its existing assets.

NRG’s focus on cash generation and shareholder returns has attracted income-focused investors seeking exposure to the energy transition. The company maintains a disciplined approach to capital allocation while benefiting from structural tailwinds in electricity demand, particularly from industrial customers and data center operators establishing facilities in Texas.

4. Howmet Aerospace (HWM)

Why Howmet Aerospace Is A Top Performer

Howmet Aerospace’s 70% appreciation reflects the aerospace industry’s robust recovery and the company’s specialized positioning in advanced materials and components. As a leading supplier of engineered products for aerospace and defense applications, Howmet benefits from both the return to growth in commercial aviation and increased defense spending driven by global security concerns.

The company’s advanced manufacturing capabilities in titanium, aluminum and nickel-based superalloys make it indispensable to aircraft manufacturers such as Boeing and Airbus. These materials require sophisticated processing techniques that create significant barriers to entry, allowing Howmet to maintain strong margins even as the industry scales up production. Long-term contracts with original equipment manufacturers provide revenue visibility and pricing power.

Defense applications represent another growth driver, with governments worldwide modernizing their military aircraft fleets. Howmet’s components are critical for next-generation fighter jets and defense systems, creating a stable revenue base that complements cyclical demand in the commercial aerospace sector. The company’s technical expertise and manufacturing scale position it well for continued outperformance.

5. Seagate Technology (STX)

Why Seagate Technology Is A Top Performer

Seagate’s 67% rally reflects the transformation of the data storage industry, driven by the growing demands of artificial intelligence and cloud computing. While solid-state drives have captured consumer mindshare, traditional hard disk drives remain essential for hyperscale data centers requiring massive storage capacity at reasonable costs. AI training and inference generate enormous data sets that must be stored efficiently and accessed reliably.

The company has successfully repositioned itself from a consumer-focused commodity manufacturer to a provider of enterprise infrastructure. Cloud service providers, such as Amazon, Microsoft and Google, require petabytes of storage capacity, and Seagate’s high-capacity drives offer the most cost-effective solution for “cold” data storage. This market dynamic has significantly improved pricing power and margins.

Seagate’s investments in advanced recording technologies, including heat-assisted magnetic recording (HAMR), enable higher storage densities that maintain the company’s competitive edge. As data generation accelerates across industries, Seagate benefits from structural demand growth that is expected to persist regardless of broader economic conditions.

Honorable Mentions

While NVIDIA’s 25% gain might seem modest compared to our top five, the chip giant’s massive $4 trillion market cap makes percentage moves more challenging to achieve. Similarly, Microsoft’s 12.2% and Meta’s 18.5% returns represent solid performance for megacap technology stocks, though they were outpaced by more specialized players positioned in high-growth niches.

Bottom Line

The 2025 market leaders share common themes: exposure to artificial intelligence infrastructure, energy transition dynamics and specialized market positions that create competitive moats. These aren’t momentum plays or speculative bets – they’re established companies benefiting from powerful secular trends reshaping the global economy. While past performance doesn’t guarantee future results, these standout performers demonstrate how identifying the right structural trends can generate exceptional returns even among large, established companies.
