According to its IPO prospectus, the company plans to sell 555.6 million shares at $135 each, raising $75 billion and valuing the company at $1.77 trillion. On a fully diluted basis, the valuation exceeds $1.8 trillion. The offering is scheduled to price on June 11, with shares expected to begin trading the next day.<\/p>\n<p class=\"yf-1fy9kyt\">However, the sector also received a boost from SpaceX&#8217;s IPO filing, which described its opportunity as the &#8220;largest actionable total addressable market in human history&#8221; and estimated a $28.5 trillion market spanning launch services, Starlink connectivity, direct-to-cell communications, and AI infrastructure.<\/p>\n<p>      <strong>SpaceX&#8217;s S&amp;P 500 Setback<\/strong>    <\/p>\n<p class=\"yf-1fy9kyt\">S&amp;P Dow Jones Indices said on Thursday that \u201cno changes\u201d would be made to the eligibility criteria for the S&amp;P 500, S&amp;P MidCap 400 and S&amp;P SmallCap 600 after its consultation on the treatment of newly listed megacap firms. The index provider said that financial viability requirements, IPO seasoning periods, and minimum investable weight-factor rules would remain unchanged.<\/p>\n<p class=\"yf-1fy9kyt\">S&amp;P said, &#8220;exceptions to the financial viability, seasoning, and IWF requirements should not be granted solely based on market capitalization.&#8221; The ruling is a hurdle for SpaceX, which posted a $4.94 billion net loss in 2025. S&amp;P 500 constituents must generate positive GAAP earnings in both the latest quarter and the trailing four quarters to qualify for inclusion.<\/p>\n<p>    Story Continues  <\/p>\n<p class=\"yf-1fy9kyt\">While S&amp;P rejected proposals that could have accelerated SpaceX&#8217;s entry into the S&amp;P 500, S&amp;P MidCap 400, and S&amp;P SmallCap 600, it did approve changes for its broader S&amp;P Total Market Index, S&amp;P Completion Index, and Dow Jones U.S. Total Stock Market Index. Under the revised rules, certain large IPOs can qualify for fast-track inclusion if they meet updated float-adjusted market cap requirements, allowing them to be added with five business days&#8217; notice.<\/p>\n<p>       <strong>SpaceX&#8217;s Passive-Buying Thesis Takes A Hit<\/strong>   <\/p>\n<p class=\"yf-1fy9kyt\">The consultation drew attention from investors as a rule change could have accelerated SpaceX&#8217;s entry into the S&amp;P 500, potentially forcing trillions of dollars in passive index funds to purchase shares shortly after the company&#8217;s debut. Tesla influencer Alexandra Merz, CEO of L&amp;F Investor Services, had previously laid out a scenario in which accelerated index inclusion and SpaceX&#8217;s relatively limited public float could compress the traditional IPO demand cycle.<\/p>\n<p class=\"yf-1fy9kyt\">Posting on X under the handle TeslaBoomerMama, Merz had estimated <a href=\"https:\/\/stocktwits.com\/news-articles\/markets\/equity\/spacex-ipo-etf-demand-vanguard-qqq-tesla-influencer\/cZQMjCvRe7r\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:last month;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;last month&quot;}\" class=\"link \">last month<\/a> that Nasdaq-100 index funds could eventually be required to purchase between $8 billion and $12 billion worth of SpaceX stock. She also projected that FTSE Russell indexes could contribute another $10 billion to $15 billion in demand, while CRSP benchmarks tracked by Vanguard funds could add between $15 billion and $25 billion in demand, based on float-adjusted market cap.<\/p>\n<p class=\"yf-1fy9kyt\">After S&amp;P\u2019s late Thursday announcement, Merz criticized S&amp;P&#8217;s decision: &#8220;S&amp;P will regret this,&#8221; she said on X. &#8220;I am certain that many investors will want index funds that have SpaceX, Anthropic and OpenAI in them. Well, they will move to Nasdaq 100 rather than S&amp;P index funds.&#8221; She added that &#8220;S&amp;P has never been friendly with Elon&#8217;s company, that&#8217;s not news.&#8221;<\/p>\n<p>     <strong>SpaceX Still Has Index Paths<\/strong>   <\/p>\n<p class=\"yf-1fy9kyt\">Nasdaq has already modified its rules to make it easier for newly listed megacap companies such as SpaceX, Anthropic, and OpenAI to join the Nasdaq-100. Under the revised rules, some of the largest IPOs can become eligible after as few as 15 trading days.<\/p>\n<p class=\"yf-1fy9kyt\">Nasdaq-100 index funds would then be required to purchase a sizable portion of publicly available shares of SpaceX. SpaceX has also become eligible for inclusion in FTSE Russell benchmarks under newly adopted fast-entry rules.<\/p>\n<p>     <strong>How Do Retail Traders Feel About Space Stocks?<\/strong>   <\/p>\n<p class=\"yf-1fy9kyt\">On Stocktwits, SpaceX drew &#8216;extremely bullish&#8217; sentiment amid &#8216;extremely high&#8217; message volume. Retail sentiment for ASTS was &#8216;bearish&#8217; and on RKLB was &#8216;neutral&#8217;, both amid &#8216;low&#8217; message volume. RDW carried &#8216;extremely bullish&#8217; sentiment with &#8216;high&#8217; message volume, while SIDU remained &#8216;bullish&#8217; amid &#8216;normal&#8217; message volume.<\/p>\n<p class=\"yf-1fy9kyt\">Over the past year, RKLB has surged 346%, ASTS has gained 274%, SIDU has advanced 218%, while RDW is up 26%.<\/p>\n<p class=\"yf-1fy9kyt\">For updates and corrections, email newsroom[at]stocktwits[dot]com.<\/p>\n<p class=\"yf-1fy9kyt\">Read Next: <a href=\"https:\/\/stocktwits.com\/news-articles\/markets\/equity\/gilead-merck-eli-lilly-lead-106-billion-takeover-wave-in-2026\/cZ0FblYRezX\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:Gilead, Merck, Eli Lilly Lead $106B Biopharma Takeover Wave In 2026;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;Gilead, Merck, Eli Lilly Lead $106B Biopharma Takeover Wave In 2026&quot;}\" class=\"link \">Gilead, Merck, Eli Lilly Lead $106B Biopharma Takeover Wave In 2026 <\/a><\/p>\n<p class=\"yf-1fy9kyt\">Deepti Sri has no position in any of the stocks mentioned in this article.
