Big Tech,Attributed to multiple references: also known as the tech giantsAttributed to multiple references: or tech titans,Attributed to multiple references: are the largest and most powerful technology companies in the world. It most commonly refers to the five dominant companies in the U.S. technology industry—Microsoft, Apple, Alphabet (Google), Amazon, and Meta (Facebook)—which are also some of the largest companies in the world by market capitalization, making up about a quarter of the S&P 500.Attributed to multiple references: Other large technology companies, such as Netflix, Nvidia, Tesla, and SpaceX, are sometimes included but usually referred to separately. The term Big Tech is similar to terms for other powerful industries, such as Big Media, Big Oil, Big Pharma, and Big Tobacco. Careers in Big Tech, particularly in technical fields such as software engineering and product management, are considered highly competitive.
History In the late 20th century, IBM, Microsoft, and Apple dominated the worldwide information technology industry. After the dot-com bubble wiped out most of the Nasdaq Composite stock market index, surviving tech startups expanded their market share and became dominant in their markets. The term Big Tech began to appear around 2013, when some economists speculated that a lack of regulation could lead to concentrated market power. The concept of Big Tech is similar to how the largest oil companies were called Big Oil following the 1970s energy crisis, and the largest cigarette producers were called Big Tobacco, as Congress attempted to regulate those industries. It is also similar to how, at the beginning of the 21st century, the mainstream media became dominated by a small number of corporations called Big Media or the media giants.
Nicknames Acronyms Acronyms including FANG, FAANG, GAFA, GAFAM, MAGA, and MAMAA have been used to refer to Big Tech companies. Alphabet (formerly Google) may be represented by G, and Meta (formerly Facebook), may be represented by F. In 2026, due to the AI boom, Jim Cramer referred to Meta, Anthropic, Nvidia, Google, OpenAI, and SpaceX as MANGOS.
Jim Cramer coined the acronym FANG in 2013, referring to Facebook, Amazon, Netflix, and Google. Cramer called them "totally dominant in their markets." Cramer stated that the four companies were poised to "take a bite out of" the declining market, giving a double meaning to the acronym, according to Cramer's colleague at RealMoney.com, Bob Lang. Cramer expanded FANG to FAANG in 2017, adding Apple to the list because its revenue made it a potential Fortune 500 company.
Following Facebook's name change to Meta Platforms in October 2021, as well as the 2015 creation of Google holding company Alphabet, Cramer suggested replacing FAANG with MAMAA, replacing Netflix with Microsoft because Netflix's valuation had fallen behind the other companies. With Microsoft, these companies were each valued at over compared to Netflix's . In November 2021, The Motley Fool suggested MANAMANA (a reference to the 1968 song "Mah Nà Mah Nà") as an acronym for Microsoft, Apple, Netflix, Alphabet, Meta, Amazon, Nvidia, and Adobe.
Internationally, Baidu, Alibaba, Tencent, and Xiaomi, collectively referred to as BATX, are considered Chinese competitors to Big Tech. In 2019, Amy Webb referred to the Big Five, IBM, Alibaba, Baidu, and Tencent as G-MAFIA BAT.
Big Four
In the early 2010s, Alphabet, Amazon, Apple, and Meta were referred to as the Big Four, The Four, the Gang of Four, and the Four Horsemen. Eric Schmidt, Phil Simon, and Scott Galloway grouped the Big Four together based on their ability to create social change. They serve billions of users, and are able to influence user behavior and control large amounts of user data. As such, they have been criticized for creating a new economic order called surveillance capitalism. According to Simon and Galloway, this distinguishes them from other Big Tech companies such as Microsoft and IBM.
In 2011, Google executive chair Eric Schmidt excluded Microsoft from the group, stating, "Microsoft is not driving the consumer revolution in the minds of the consumers." In the late 2010s, Microsoft changed its business strategy, causing its market value to increase, leading to its widespread inclusion in Big Tech and creating the term Big Five.
Big Five
Alphabet, Amazon, Apple, Meta, and Microsoft are referred to as the Big Five. They are among the most valuable public companies. In 2020, the Big Five were the second through sixth most valuable public companies in the world, behind Saudi Aramco. In August 2020, the Big Five accounted for nearly a quarter of the S&P 500. In March 2023, Apple and Microsoft accounted for 13% of the S&P 500. The Big Five are among the most prestigious employers in the world.
In the 21st century, the Big Five surpassed the market capitalization of the Big Oil companies BP, Chevron, ExxonMobil, and Shell. In 2019, Jason Whittaker stated that they also outpaced Big Media companies such as Comcast, Disney, and Warner Bros. Discovery by a factor of 10. In 2017, the Big Five had a combined value of over $3.3 trillion, and made up almost half of the Nasdaq-100.
Magnificent Seven A group referred to as the Magnificent Seven adds Nvidia and Tesla to the Big Five based on their contributions to the S&P 500. In 2023, the Magnificent Seven accounted for approximately two-thirds of the S&P 500's gains. Over the course of the year, the Magnificent Seven delivered a groundbreaking 107% return on investment, which analysts credited to the AI boom and expected interest rate cuts by the Federal Reserve. By May 30 of that year, all of the Magnificent Seven had seen peak market caps of at least $1 trillion.
By January 2024, the Magnificent Seven accounted for 29% of the S&P 500. In February 2024, as the Magnificent Seven approached a combined valuation of $13 trillion, Deutsche Bank stated that the group exceeded the valuation of the total stock market in every country in the world except Japan, China, and the United States.
By mid-2024, Morgan Stanley stated that the Magnificent Seven accounted for 31% of the S&P 500. Some analysts expressed concern that the group's extreme concentration could trigger a downturn similar to the dot-com crash or the crash of 1929. Others argued that the companies could continue to outperform the broader market. On August 5, 2024, the Magnificent Seven briefly lost $1 trillion before quickly recovering, with the drop attributed to disappointing economic reports and growing concerns of AI overinvestment. In May 2025, FTSE Russell launched a Russell Magnificent 7 Index. In July 2026, S&P Dow Jones Indices launched an S&P 500 Magnificent 7 Index.
The nickname Magnificent Seven was coined in May 2023 by Bank of America analyst Michael Hartnett as a reference to the 1960 film of the same name, and popularized by Jim Cramer on Mad Money.
Noble Nine The Noble Nine adds Broadcom and SpaceX to the Magnificent Seven. Broadcom surpassed both Meta and Tesla in early 2026 in terms of market capitalization, and the initial public offering of SpaceX on June 11, 2026 placed SpaceX above Broadcom, at a valuation of around $2.1 trillion.
