Key Points
- SpaceX’s projected IPO valuation leaves minimal margin for error.
- Historical data from Jay Ritter indicates that overpriced IPOs frequently underperform the broader market.
- Declining ARPU for Starlink and ongoing operating losses introduce significant risk factors.
SpaceX is positioned to be one of the most anticipated IPOs in Wall Street history. With its Starlink satellite constellation, reusable rocket technology, deep government ties, and strong commercial momentum, the company possesses a rare and credible high-growth narrative.

Reports from Reuters suggest SpaceX is targeting a valuation of $1.75 trillion, which implies a price-to-sales (P/S) ratio nearing 100. At such a premium, public investors would essentially be paying for years of future success before those results are fully realized. While SpaceX is an engineering marvel, the critical question for investors is whether it will be an equally successful financial investment.
A Warning from Historical Data
Jay Ritter, a leading expert on IPO performance, has analyzed U.S. IPO data from 1980 through 2025. His research reveals a sobering trend: among IPOs with more than $100 million in sales and a P/S ratio exceeding 40 at the offer price, 12 out of 14 underperformed the market over the following three years. The only exceptions were Mobileye Global and Astera Labs, proving that fundamentally exceptional companies can defy the odds. However, history suggests that investors buying into such richly valued offerings are often better off waiting or seeking other opportunities.
With an expected P/S ratio of nearly 100, SpaceX would require near-perfect execution and extraordinary growth to justify its price tag.
Critical Risks to Consider
While Starlink’s subscriber base has grown impressively—rising from 2.3 million at the end of fiscal 2023 to 10.3 million by the first quarter of fiscal 2026—the average revenue per user (ARPU) has trended downward. Monthly ARPU fell from $99 in 2023 to $81 in 2025, reaching $66 by the first quarter of 2026. SpaceX attributes this decline to the introduction of lower-priced plans and expansion into international markets. To justify a 100x multiple, Starlink must demonstrate that global scaling can occur without transforming the business into a low-margin telecom provider.
The Starship reusable rocket system is another pivotal catalyst. The 12th test flight since 2023—and the first for the upgraded V3 version—met most of its primary objectives. Success here is vital, as Starship could significantly lower the cost of deploying Starlink satellites and open new markets. However, the system remains unproven; any further technical setbacks or delays could undermine the company’s premium valuation.
Profitability also remains a hurdle. Despite Starlink generating an operating profit in the first quarter, SpaceX reported a total operating loss of $1.94 billion on $4.69 billion in revenue. While the company may be approaching a point of durable cash flow, the current valuation leaves very little room for operational missteps.
This does not mean a SpaceX IPO is destined for failure; the company may indeed be one of the few entities capable of growing into such a massive valuation. However, at nearly 100 times sales, the downside risk for investors is substantial.
