Michael Saylor wants SpaceX in the 'Mag 8' and says its Bitcoin holdings are why
Michael Saylor has put SpaceX inside Wall Street’s top technology group after the rocket company joined public markets at a value above $2 trillion. The Strategy (NASDAQ: MSTR) executive chairman posted on X after the June 12, 2026 listing and used the name “Mag8.”
Saylor wrote, “Congratulations @ElonMusk and $SPCX on a historic IPO. Thanks to you, 25% of the Mag8 now holds Bitcoin on the balance sheet.”
The SpaceX ($SPCX) offering became the largest IPO ever completed in the United States. Its opening valuation placed the company ahead of Tesla (NASDAQ: TSLA) and Meta Platforms (NASDAQ: META). Both were already included in the Magnificent Seven. That left investors with a simple problem. A company worth more than two members of the group was sitting outside the name. OpenAI and Anthropic are also possible IPO candidates, so the old label could become outdated quickly.
SpaceX forces Wall Street to rethink the name of its biggest stock group
Shay Boloor, chief market strategist at Futurum Equities, said Mag7 no longer gives investors the full picture. “It becomes very hard to keep using Mag 7 as the clean shorthand for market leadership because one of the most important companies in the world would immediately be outside the label,” he said.
These names are not official stock market categories. Banks, traders, investors, and financial media create them to describe companies receiving the most attention at a particular time. Wall Street has used this habit for decades. The “Nifty 50” covered popular large companies during the 1960s and 1970s. The “Four Horsemen” became a common term for major technology stocks during the late 1990s dot-com boom.
The SpaceX listing has now started another naming contest. One option spreading on X is “MANGOS.” One version includes Meta (NASDAQ: META), Anthropic, Nvidia (NASDAQ: NVDA), Alphabet (NASDAQ: GOOGL), OpenAI, and SpaceX. Some investors use Apple (NASDAQ: AAPL) for the letter A instead of Anthropic. Apple is currently the third-largest U.S.-listed company by market value.
Aga Kuplinska, senior vice president of product development at Tidal Financial Group, said the term is already being used inside the industry. “We are already referring to it internally and the industry is picking up on it as well,” she said. Tidal works with asset managers that want to launch exchange-traded funds.
Dan Boardman-Weston, chief executive of BRI Wealth Management, suggested another option. He called it “Magna Atoms.” His version would combine the current seven companies with SpaceX, OpenAI, and Anthropic.
Bitcoin and AI reshape the list of companies controlling market weight
Michael Hartnett, chief investment strategist at BofA Global Research, created the Magnificent Seven name in late 2023. The group included Nvidia (NASDAQ: NVDA), Apple (NASDAQ: AAPL), Amazon (NASDAQ: AMZN), Alphabet (NASDAQ: GOOGL), Meta (NASDAQ: META), Tesla (NASDAQ: TSLA), and Microsoft (NASDAQ: MSFT).
Earlier versions had already changed several times. FANG included Facebook, Amazon, Netflix (NASDAQ: NFLX), and Google. FAANG later added Apple. The Magnificent Seven removed Netflix and brought in Microsoft, Nvidia, and Tesla.
BofA expanded the idea again in a May 22 note, creating an “AI Big 10” by adding Broadcom (NASDAQ: AVGO), Micron Technology (NASDAQ: MU), and Advanced Micro Devices (NASDAQ: AMD) to the original seven. As of press time, LSEG data placed those ten companies at more than 40% of the S&P 500 by weight.
Saylor’s post also drew attention to the Bitcoin treasury disclosed by SpaceX in its SEC S-1 filing. The company reported 18,712 BTC worth about $1.18 billion at current prices. That total made SpaceX the eighth-largest publicly traded corporate holder of Bitcoin after its IPO.
Strategy remains the largest institutional Bitcoin holder. The company added more than 90,000 BTC during the first quarter of 2026 and passed BlackRock’s iShares Bitcoin Trust (NASDAQ: IBIT). It also sold 32 BTC for about $2.5 million in late May to cover required quarterly dividends on preferred shares. That transaction was Strategy’s first Bitcoin sale since 2022.
Strategy records its Bitcoin at fair market value. That accounting method can cause major changes in reported profit and company valuation whenever Bitcoin’s market price rises or falls.
