S&P Dow Jones is considering rule modifications that could fast-track unprofitable giant IPOs like SpaceX into major indexes
With approximately $20 trillion tied to S&P 500 benchmarks, index funds may face mandatory SpaceX purchases regardless of fundamentals

Elon Musk’s SpaceX is preparing for its market debut on the Nasdaq exchange this June 12, trading under ticker symbol SPCX with a targeted market capitalization approaching $2 trillion. This positioning would establish it as the most valuable company to ever launch an initial public offering in American financial history.

SpaceX filed its amended IPO filing (S-1/A) today.

The aerospace manufacturer submitted its S-1 registration documentation on May 20, following confidential filing submissions to the Securities and Exchange Commission back in April.

Financial Performance Shows Decelerating Momentum

SpaceX operates through three primary business divisions: space operations, connectivity services, and artificial intelligence. Currently, the connectivity division generates the largest portion of revenues, driven primarily by its Starlink satellite broadband network.

Throughout 2025, the company achieved $18.6 billion in revenue, representing 33% year-over-year expansion—down from the previous year’s 35% growth rate. Despite this revenue performance, SpaceX recorded a $4.9 billion operating deficit for the period.

The most recent quarter (Q1 2026) revealed further deceleration, with revenue advancing only 15% while operating losses expanded to $1.9 billion. These figures reflect aggressive capital deployment into rocket development and AI computing infrastructure.

A significant revenue opportunity emerged in May when Anthropic committed to a three-year contract worth $1.25 billion monthly for access to SpaceX’s Colossus supercomputing systems. This arrangement could substantially enhance AI division revenues starting in the latter half of 2026.

SpaceX’s artificial intelligence operations launched following its acquisition of xAI earlier this year. The AI segment now encompasses cloud infrastructure services, Colossus supercomputer access, and the Grok family of AI language models.

Unprecedented Valuation Metrics Raise Concerns

At its anticipated IPO pricing, SpaceX trades at approximately 103 times trailing sales. By comparison, Palantir currently commands the S&P 500’s highest price-to-sales multiple at 72x. SpaceX would enter the market priced 40% higher on this metric.

An examination of over 100 technology companies identified only eight instances where stocks traded above 100 times sales. Every single case resulted in severe subsequent declines, with drops spanning 32% to 90% and averaging a 75% drawdown from peak valuations.

Historical IPO performance data adds another layer of caution. While newly public stocks have averaged 30% first-day gains since 2020, the ten largest U.S. IPOs on record have collectively underperformed the S&P 500 by an average of 127 percentage points from their listing dates.

Proposed Index Revisions Could Trigger Forced Institutional Buying

S&P Dow Jones Indices initiated a public consultation on April 30 regarding potential modifications to inclusion criteria for major companies. The proposals include reducing the required seasoning period from twelve months to six, eliminating profitability requirements for mega-capitalization stocks, and potentially relaxing float standards.

The comment period for this consultation concluded May 28. Should S&P adopt these changes, implementation would begin June 8—merely four days prior to SpaceX’s trading debut.

Current expectations suggest SpaceX will float approximately 5% of total shares outstanding. This limited availability presents complications for index-tracking funds, which could face requirements to purchase shares in a $2 trillion enterprise with minimal tradable supply.

Goldman Sachs research estimates that Nasdaq’s expedited entry rule modifications alone might generate up to $60 billion in mandatory purchasing activity within just the Nasdaq-100. The S&P 500 commands significantly larger tracking capital—approximately $20 trillion in assets either indexed or benchmarked to it.

Nell Minow, a recognized authority on corporate governance, told Fortune that these rule adjustments contradict fundamental index principles. She anticipates major institutional investors may advocate for alternative benchmark indexes that exclude companies entering under these modified standards.
