Investors: This Might Be the Easiest Way to Buy SpaceX, OpenAI, and Anthropic After Their IPOs

SpaceX is targeting what could be the largest IPO in market history, with OpenAI and Anthropic also expected to come public in the near future. The article argues that investors may be better off gaining exposure through broad ETFs such as VOO or VTI rather than trying to buy these names on day one, especially since blockbuster IPOs have historically underperformed early. It also notes that S&P 500 inclusion would likely take at least 12 months, while Nasdaq-100 and Russell 1000 rules could admit IPOs faster.

Analysis

The immediate market impact is less about the IPOs themselves and more about the indexing pipeline they create. The bigger second-order winner is passive AUM: once a mega-private becomes eligible for broad benchmarks, forced buying from indexers can overwhelm fundamental valuation discipline, especially in the first rebalance window. That argues for a temporary mispricing regime where price discovery is dominated by flows rather than earnings power.

The closest public-market beneficiaries are not necessarily the issuers, but the platforms and enablers that capture trading, custody, and financing activity around the listing cycle. Higher attention to AI-private-market leaders also tends to re-rate public AI infrastructure names on sympathy trades, particularly where investors want liquid exposure before the IPOs are actually tradable. For the names in scope, the most interesting knock-on is that a successful listing binge could extend the duration of AI capex enthusiasm, but it also raises the probability of capital rotation out of the highest-multiple public winners once the new issues absorb incremental risk appetite.

The contrarian risk is that blockbuster IPOs often arrive when sentiment is already maxed and volatility is underpriced. If post-listing performance disappoints, broad benchmarks get the exposure anyway while late entrants into the story wear valuation compression. That makes the first 1-3 months after any inclusion event a poor time to chase; the better window is either pre-inclusion via proxies or after the initial lockup/first earnings reset, when supply meets reality.

Key Decisions for Investors

• Prefer a basketed proxy over single-name IPO chasing: accumulate broad index exposure via VTI/VOO on any post-listing pullback; expected return is lower but drawdown risk is materially better than buying new issues in the first 30-90 days.
• Trade the inclusion lag: go long NDAQ versus short a broad beta proxy around confirmed index-addition dates; index reconstitution flows should support exchange economics while the broad ETF leg buffers market risk.
• Use public AI infrastructure as the cleaner expression of the theme rather than the IPOs themselves: long NVDA on weakness, but size modestly and use 6-12 month horizon because the trade depends on AI capex staying elevated after the IPO cycle.
• Sell upside volatility in the hot-IPO complex through call spreads or defined-risk short gamma once listing dates are set; implied vol should stay rich into debut, but history favors mean reversion after initial enthusiasm fades.
• Do not short the issuers directly on day 1; if the story breaks, it will likely be via index-flow exhaustion and lockup overhang after several weeks, not immediate collapse. Reassess for short opportunities only after the first earnings print or inclusion event.
