SpaceX IPO Marks Shift in Tech Market Leadership, Sparks Search for 'Magnificent Seven' Successor

Elon Musk's SpaceX launched on the Nasdaq on June 12, 2026, under ticker symbol SPCX, marking a major milestone in the aerospace and technology sectors. By June 16, the stock had surged 12%, reaching a market capitalization of $285 billion, enabling SpaceX to overtake three members of the "Magnificent Seven" — Tesla, Meta, and Amazon. Since its IPO, SpaceX shares have climbed 35%, underscoring strong investor appetite for the company.

The SpaceX debut has prompted Wall Street to reconsider the "Magnificent Seven" designation, which traditionally comprises Nvidia, Apple, Alphabet, Microsoft, Amazon, Meta, and Tesla. Market observers and financial institutions are now debating replacement frameworks that better reflect the current landscape of artificial intelligence and big technology companies.

Two prominent candidates have emerged. Vanda Research proposed "FAB 10" (Frontier AI & Big Tech 10), which adds SpaceX, OpenAI, and Anthropic to the original seven. A competing term, "MANGOS" (Meta, Anthropic, Nvidia, Google, OpenAI, SpaceX), gained rapid traction after a developer's social media post garnered millions of views in June. MANGOS notably replaces traditional consumer internet companies—Apple, Microsoft, Amazon, and Tesla—with AI-focused entities. Corgi Funds submitted a prospectus for a MANGOS-branded ETF this week, though critics have noted the irony that two of the six constituent companies, Anthropic and OpenAI, remain unlisted.

Both Anthropic and OpenAI, which pursue IPOs later in 2026, filed confidential regulatory documents in June and could each achieve valuations exceeding $1 trillion at public listing. Their continued private status creates a structural challenge for any index or fund attempting to track the proposed new groupings, as most investors cannot fully replicate the composition.

Meanwhile, the traditional Magnificent Seven has faced headwinds. The Roundhill Magnificent Seven ETF (MAGS) declined approximately 4.7% over the past month, with Microsoft shares down 17% year-to-date and Meta and Tesla shares each down roughly 8%. These declines reflect broader market reallocation toward artificial intelligence and aerospace technologies exemplified by SpaceX's strong performance.
