S&P Dow Jones Indices has declined to modify its entry requirements for the S&P 500 index, effectively delaying the inclusion of SpaceX following its planned initial public offering.

S&P Dow Jones Indices 拒絕修改 S&P 500 指數的入選要求，有效地推遲了 SpaceX 在計劃首次公開發行後的納入時間。

The decision by S&P Dow Jones Indices follows a month-long consultation regarding the potential relaxation of standards for 'MegaCap' entities. Specifically, the index provider considered reducing the mandatory twelve-month seasoning period to six months, waiving the requirement for a ten percent investable weight factor (IWF), and suspending the necessity for demonstrated GAAP profitability. S&P Dow Jones Indices ultimately determined that market capitalization alone does not justify exceptions to these financial viability and liquidity screens. Consequently, SpaceX—which targets a valuation of $1.75 trillion but reported a net loss of $4.94 billion in 2025 and maintains a public float of approximately 3-4%—remains ineligible for entry until at least June 2027, contingent upon achieving profitability and increasing its public share availability.

S&P Dow Jones Indices 的這項決定是在針對「超大型」實體放寬標準進行為期一個月的諮詢後做出的。具體而言，指數提供商考慮將強制性的十二個月緩衝期縮短至六個月，豁免百分之十的可投資權重因子 (IWF) 要求，並暫停對 GAAP 獲利能力的證明要求。S&P Dow Jones Indices 最終認定，單憑市值不足以成為豁免這些財務可行性與流動性篩選的理由。因此，SpaceX——儘管目標估值為 1.75 兆美元，但 2025 年報告淨虧損 49.4 億美元，且公眾持股比例約為 3-4%——在至少 2027 年 6 月之前仍不符合入選資格，前提是需實現獲利並增加公眾持股比例。

This institutional rigidity contrasts with the strategic rapprochement observed at other index providers. The Nasdaq and FTSE Russell have implemented expedited entry protocols, allowing large-scale IPOs to enter the Nasdaq-100 and Russell Top 500 indexes within significantly shorter timeframes. Such divergent methodologies create a disparity in passive capital inflows; while S&P 500 inclusion could have triggered an estimated $10 billion to $14 billion in automatic purchases, SpaceX will instead rely on the accelerated pathways provided by other benchmarks. Furthermore, S&P Dow Jones Indices granted a limited concession by modifying IWF rules for lower-profile benchmarks, such as the S&P Total Market Index.

這種制度上的僵化與其他指數提供商所採取的策略性接洽形成對比。Nasdaq 與 FTSE Russell 已實施快速入選協議，允許大規模 IPO 在顯著較短的時間內進入 Nasdaq-100 與 Russell Top 500 指數。這種截然不同的方法造成了被動資本流入的差異；雖然納入 S&P 500 可能會觸發估計 100 億至 140 億美元的自動買入，但 SpaceX 將轉而依賴其他基準指數提供的加速路徑。此外，S&P Dow Jones Indices 透過修改低知名度基準（如 S&P 全市場指數）的 IWF 規則，做出了一定程度的讓步。

Parallel to these developments, the broader equity market continues to integrate AI-centric infrastructure firms. Marvell Technology is scheduled for inclusion in the S&P 500 on June 22, having satisfied the requisite profitability hurdles. This addition, alongside the inclusion of Flex, underscores a systemic shift toward semiconductor and data-center entities. Simultaneously, J.P. Morgan has adjusted its valuation of Tesla to 'neutral,' attributing this shift to the company's vertical integration of robotics and autonomous systems, which may decouple its market value from immediate earnings performance.

與這些發展平行，更廣泛的股票市場繼續整合以 AI 為中心的基礎設施公司。Marvell Technology 因滿足了獲利門檻，預計將於 6 月 22 日納入 S&P 500。此次納入連同 Flex 的加入，凸顯了向半導體與數據中心實體轉移的系統性趨勢。同時，J.P. Morgan 將 Tesla 的估值調整為「中立」，將此轉變歸因於該公司在機器人與自動化系統的垂直整合，這可能會使其市場價值與即時盈利表現脫鉤。

While SpaceX will achieve public listing and entry into several major indexes, the S&P 500 maintains its stringent profitability and seasoning requirements, forestalling immediate passive fund inflows.

雖然 SpaceX 將實現公開上市並進入數個主要指數，但 S&P 500 維持其嚴格的獲利與緩衝期要求，阻礙了即時被動基金的資本流入。
