Is the US stock market's 'Big Seven' getting a new name: 'MANGOS' ? With SpaceX hitting the US stock market at a valuation of over $2 trillion, it has surpassed Tesla and Meta in market cap. The Mag7 'Big Seven' can no longer contain the luxurious new lineup of 'AI + Aerospace.' SpaceX, OpenAI, and Anthropic are squeezing into Wall Street's group chat. Wall Street has already started giving the next-gen tech giants a nickname, and the hottest one right now is 'MANGOS,' representing Meta, Anthropic, Nvidia, Alphabet, OpenAI, and SpaceX. The name might not change immediately, but the signal is clear: the list of the strongest companies in the US stock market is being rewritten by AI and commercial aerospace.
