*aerospace · news · 2026-05-26 · Benzinga*

## Key points

- 納斯達克規則變更允許像 SpaceX 這樣的新上市公司在 15 天內加入指數。
- 納斯達克 100 指數的 10% 自由流通股要求已被取消。
- 由於這些變更，強制指數基金買盤可能引發對 SpaceX 220 億至 270 億美元的 ETF 資金流入。
- SpaceX 現可在 IPO 後六個月內有潛力加入標普 500 指數，而非 12 個月。

As SpaceX gears up for its blockbuster IPO, Nasdaq could face lawsuits from index funds as the Nasdaq 100 rule changes trigger investments into the commercial space flight giant. Analyst Says Nasdaq Could Be Sued On Monday, economist and co-founder of the Center for Economic and Policy Research, Dean Baker, quoted a post by user @blockchainchick who criticized the SpaceX IPO as “the most brazen retail fleecing in modern market history,” pointing to rule changes by the Nasdaq that would force investments into the IPO. “I assume SpaceX shareholders, especially the accidental ones in index funds (good time to get out), could sue NASDAQ for these rule changes,” Baker said in the post. Nasdaq 100, S&P 500 Rule Changes The rule changes adopted by the Nasdaq would help expedite SpaceX’s entry into the index, as the new rules would add new companies to the index within 15 days of their public listing if the enterprise’s "entire market capitalization ranks within the top 40 current constituents in the index." The new rules also eliminate the clause that states companies traded on the index must maintain a 10% free-float, which means that companies on the index would no longer need to maintain 10% shares available to be traded publicly. Analysts estimate the rule changes could trigger roughly $22 billion to $27 billion in forced ETF buying from physically backed index funds alone SpaceX could also be fast-tracked into the S&P 500 index, as the rule changes would allow companies to enter the index six months after their debut on an eligible index instead of 12 months.
