争议焦点不只在规模，也在治理与定价。若以 1.8 兆美元市值计算，SpaceX 的股价/销售比约为 93 倍，约是 Nasdaq 100 平均值的 15 倍；同时，Musk 拟把最多 30% 的配售留给散户，约 225 亿美元，改写传统 IPO 由机构先拿货、散户后追价的流程。反对者担心低流通量、投票权与市场完整性被弱化，而支持者则认为指数应立刻反映巨型企业的真实市场地位。
更深层看，SpaceX 代表的是「火箭公司」与「AI 基础设施公司」的双重叙事：Starlink 仍是主要营收来源，去年占销售逾一半，但 Anthropic 的近 450 亿美元云端合作、以及太空资料中心构想，都在强化其科技股属性。市场上已有超过 20 档 SpaceX 相关 ETF 申请，私人市场也涌现 pre-IPO 产品；然而学者与部分资金管理人警告，若故事无法兑现，这场 mega-IPO 可能重创后续 OpenAI、Anthropic 等公司上市，也可能让整体资本市场承受失败溢出风险。
SpaceX may become the largest IPO ever, targeting $75 billion in proceeds at a valuation of at least $1.8 trillion, more than twice the size of any prior listing. Its arrival is already reshaping market infrastructure: Nasdaq, FTSE Russell, and potentially S&P Dow Jones Indices are rewriting fast-entry rules so mega-caps can join major benchmarks within 15 trading days, or even five, creating as much as nearly $20 billion of passive demand, about one quarter of the offering.
The controversy is not only about size but also governance and valuation. At a $1.8 trillion market cap, SpaceX would trade at about 93 times sales, roughly 15 times the Nasdaq 100 average; Musk is also considering reserving up to 30% of the deal, or about $22.5 billion, for retail buyers, upending the traditional IPO pattern in which institutions lead and retail follows. Critics worry that low float, voting-right concessions, and market-integrity standards are being bent, while supporters argue indexes should immediately reflect companies of this magnitude.
The deeper story is SpaceX’s dual identity as both a rocket maker and an AI infrastructure play: Starlink remains the main revenue engine, accounting for more than half of sales last year, yet an Anthropic cloud-services deal that could approach $45 billion and the idea of data centers in space are pushing the company toward a technology classification. More than 20 SpaceX-linked ETFs have already been filed, and private-market vehicles are booming, but academics and some managers warn that if the narrative fails to deliver, the IPO could hurt future mega-listings such as OpenAI and Anthropic and raise broader questions about capital-market resilience.
