Cap-weighted indices: mechanical, fast and float-driven
Capitalisation-weighted benchmarks are simple rules-based mechanisms, and the rules point in different directions. MSCI has confirmed it will apply its existing fast-track mechanism for large IPOs: if SpaceX meets the relevant requirements after listing, it could join the MSCI World and MSCI ACWI at the close of its tenth trading day, likely in late June 2026. The Nasdaq-100 has a similar fast-entry route, with eligible candidates added after 15 trading days. The S&P 500 will not include SpaceX in the near term: the index requires GAAP profitability, a condition SpaceX does not meet having reported a USD 4.9 billion net loss in 2025.
Where SpaceX does enter, the initial index footprint will be far smaller than the headline valuation suggests. With only around 4–5% of shares freely tradeable at launch, the float-adjusted market value is closer to USD 75–85 billion — implying an initial MSCI World weight of roughly 0.08–0.10%. The more important dynamic is the path: as lock-ups expire and the recognised free float expands, SpaceX's weight will increase in discrete steps, each triggering additional mechanical demand from funds tracking these benchmarks. Cap-weighted investors may therefore own SpaceX quickly, automatically and in growing size — irrespective of its valuation, profitability or risk profile.
Factor indices and risk-optimised strategies: deliberate, slower and model-driven
Factor-based products follow a different logic, selecting and weighting stocks on measured characteristics such as volatility, momentum, value or quality. MSCI's methodology for factor indices states that newly listed securities are considered only at the next semi-annual review, even if they qualify for fast-track entry in the parent index. Moreover, a newly listed company simply lacks the inputs many factor definitions require: a momentum signal conventionally needs around twelve months of returns (excluding the most recent month), while stable beta and volatility estimates are built on multi-year windows.
The same principle applies to OLZ's risk-optimised strategies. Our models require sufficient history to estimate a stock's risk metrics and its relationship with the other stocks in a robust way. Until those data requirements are met SpaceX is not investable for our strategies.
Even beyond the data threshold, SpaceX may not qualify for most factor portfolios: The company is unprofitable, trades at an exceptionally high revenue multiple, and is expected to exhibit elevated idiosyncratic volatility given its thin float and sentiment-driven investor base. A minimum-variance portfolio is unlikely to assign it a meaningful weight; value and quality screens may exclude it outright. The realistic picture is that factor and risk-optimised strategies will hold little or no SpaceX well into 2027 — the mirror image of the cap-weighted experience.
What this means for investors in OLZ funds
The SpaceX IPO illustrates that "passive" is not one single concept. A cap-weighted mandate buys what has become large, as soon as the rules allow. A risk-optimised mandate allocates only when the data history and portfolio contribution justify it. SpaceX — enormous, unprofitable, highly valued, thinly floated and exposed to significant key-person risk — is a natural candidate for rapid cap-weighted inclusion, but not for immediate entry into most factor or risk-based portfolios.
Investors in OLZ funds (including the OLZ Index Optimized strategy) will not board SpaceX at launch. We will remain on the sidelines until its risk characteristics can be assessed with the same discipline applied to every other holding. In that sense, patience is not a view on the company. It is part of the investment process.
