The 'Magnificent Seven' rule the market—but which of these giants are actually worth your money in 2026?

Synopsis

The Magnificent Seven have become so large that their performance can move the entire US stock market. Together, Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta and Tesla accounted for 33.7% of the S&P 500 in November 2026. Their combined market value was reported at $23.6 trillion. Some have delivered strong gains this year, while others have fallen behind the index.

The S&P 500 has 500 companies, but seven stocks now account for more than one-third of its total value. Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta and Tesla had a combined market capitalisation of $23.6 trillion in November 2026. Together, they represented 33.7% of the benchmark index. But there is a gap between their valuations and stock returns.

Apple has gained nearly 29% this year, while Tesla has lost more than 14%. The group has also underperformed the S&P 500 in 2026.

Here is how much each company is worth, its weight in the index and how its shares have performed.

Magnificent Seven stocks: Combined market cap reaches $23.6 trillion

The Magnificent Seven have grown into some of the most influential companies in the US stock market. All seven now have market valuations above $1 trillion. Their combined market capitalisation of $23.6 trillion makes them a major force behind the S&P 500's movements.

The group includes Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta Platforms and Tesla. Although they are commonly grouped as technology stocks, they operate across different sectors, including consumer retail, communication services and automobiles. Their businesses also have significant exposure to artificial intelligence.

Live Events

The concentration is important for investors because movements in these seven stocks can influence the performance of an entire S&P 500 index fund.

Apple stock: $5.1 trillion market cap and 28.49% gains in 2026

Apple is the largest company in the Magnificent Seven, with a market capitalisation of $5.1 trillion. It accounts for 7.3% of the S&P 500, the highest weight among the seven stocks.

Apple shares gained 28.49% in 2026 through November 4. Its one-year return stood at 29.83%. This makes Apple the strongest performer in the group over both periods.

Microsoft stock: $4 trillion valuation and 15.06% YTD returns

Microsoft has a market capitalisation of $4 trillion and represents 5.9% of the S&P 500. Its shares gained 15.06% in 2026 through November 4, while its one-year return was 7.62%.

The company remains one of the biggest contributors to the index. Its position in enterprise software, cloud computing and artificial intelligence makes it an important part of the technology market.

Nvidia stock: $4.3 trillion market cap and 6.9% S&P 500 weight

Nvidia is valued at $4.3 trillion and accounts for 6.9% of the S&P 500. It is the second-largest company in the Magnificent Seven by market capitalisation.

Its shares gained 7.36% in 2026 through November 4 but declined 3.21% over the past year. Its longer-term rise has been much bigger. In 2015, Nvidia represented less than 1% of the group's combined market value. It now contributes around 20%.

Alphabet stock: $3.5 trillion market cap despite a 7.66% decline

Alphabet, Google's parent company, has a market capitalisation of $3.5 trillion and a 5.1% weight in the S&P 500.

Its shares declined 7.66% in 2026 through November 4. However, the stock remained up 1.86% over the trailing year. Despite the recent weakness, Alphabet continues to be one of the largest companies in the index.

Amazon stock: $2.9 trillion valuation and 15.38% stock gains

Amazon has a market capitalisation of $2.9 trillion and represents 4.1% of the S&P 500.

Its shares advanced 15.38% in 2026 through November 4, beating the index's 12.32% gain. However, its one-year return was lower at 4.85%. The difference between these figures shows how its performance has improved during the current year.

Meta stock: $1.6 trillion market cap as shares fall 4.56%

Meta Platforms has a market capitalisation of $1.6 trillion and accounts for 2.3% of the S&P 500.

Its shares fell 4.56% in 2026 through November 4. The one-year return was also negative at 1.22%. Meta remains one of the largest companies in the group, but its stock performance has lagged several of its peers.

Tesla stock: $1.5 trillion valuation but the biggest Magnificent Seven decline

Tesla has a market capitalisation of $1.5 trillion and a 2.2% weight in the S&P 500.

It is the weakest performer among the seven stocks in the supplied return data. Tesla shares declined 14.35% in 2026 through November 4. Its one-year loss was even larger at 17.76%.

Despite these declines, Tesla remains a trillion-dollar company and an important part of the S&P 500.

The Magnificent Seven's combined market value has increased sharply over the past decade. The historical comparison shows their market capitalisation rising from $8.5 trillion in 2020 to $11.8 trillion in 2021. It then stood at $6.9 trillion in 2022, before recovering to $12 trillion in 2023, $17.6 trillion in 2024 and $21.2 trillion in 2025.

Their growing size has also increased their influence over index funds. Investors buying an S&P 500 fund are indirectly putting a significant portion of their money into these seven companies.

However, their 2026 performance shows the risk of this concentration. The Magnificent Seven gained 9.61% through November 4, compared with a 12.32% rise in the S&P 500. Their combined one-year return was 8.76%, while the index delivered 13.54%.
