Wall Street has embraced a new acronym, “MANGOS,” to describe a group of six companies closely associated with developments in artificial intelligence and poised to influence the stock market. The term refers to Meta, Anthropic, Nvidia, Google, OpenAI, and SpaceX, a cluster investors are increasingly watching amid optimism about the sector’s growth potential.

The emergence of the “MANGOS” label follows a tradition of market nicknames dating back to the mid-20th century, such as the “Seven Sisters” of the oil industry in the 1950s and the tech-focused “FAANG” group in more recent decades. The current cohort includes established technology giants alongside private companies making waves for their cutting-edge AI initiatives.

SpaceX’s recent initial public offering at a valuation exceeding $2 trillion helped propel the group into the spotlight. The company’s IPO, the largest to date, attracted significant interest from retail investors who have put considerable trust in CEO Elon Musk’s vision. This momentum has spurred the creation of more than a dozen mutual funds that seek exposure to MANGOS through various financial instruments, including options, enabling investors to vote for or against the prospects of these firms.

However, the group’s full composition is complicated by the fact that two members—Anthropic and OpenAI—remain privately held. Fund managers aiming to mimic their performance must rely on alternative mechanisms since these companies do not trade on public exchanges.

While the precise origin of the “MANGOS” acronym is unclear, a Bank of America analyst, Vivek Arya, noted having used the term in the past to describe a different set of chip-related stocks, rather than the current AI-associated lineup. Despite this ambiguity, the term has gained traction across business media and social platforms as shorthand for this influential set of companies driving much of the discussion around artificial intelligence’s market impact.

As the AI sector continues to evolve rapidly, the sustainability of the MANGOS group’s prominence remains uncertain. Analysts caution that while these firms may represent the forefront of technological innovation, the volatility inherent in emerging industries could mean their dominance on Wall Street might be short-lived.
