The S&P 500, one of the most widely followed stock market indexes, recently blocked the inclusion of several high-profile tech and AI companies: SpaceX, OpenAI, and Anthropic. This decision highlights a crucial aspect of how major indexes are constructed: they prioritize consistent profitability over even immense private valuations or future potential. For everyday investors, this means that while these companies are making headlines, they won't yet be part of many retirement funds or broad market portfolios that track the S&P 500.
The S&P 500 is a stock market index that tracks the performance of 500 of the largest publicly traded companies in the United States. Inclusion in this index is a big deal for a company because it often leads to a significant bump in stock price. That's because countless investment funds, from passive index funds to active mutual funds, are designed to mirror the S&P 500's composition. When a company joins, these funds automatically buy its stock, creating instant demand.
The core issue for SpaceX, OpenAI, and Anthropic is the S&P 500's strict profitability rule. To be eligible, a company must have positive earnings for at least the most recent quarter, and its total earnings over the past four consecutive quarters must also be positive. While these companies boast staggering valuations in the private markets (SpaceX is valued over $200 billion, OpenAI and Anthropic are in the tens of billions), they haven't consistently turned a profit. OpenAI and Anthropic, for instance, are still heavily investing in research and development for their LLMs (large language models, the sophisticated AI behind chatbots like ChatGPT), which often means burning through cash in the short term.
This situation underscores a broader tension in today's tech landscape. Many of the most innovative and impactful companies, particularly in AI, are still in a growth-at-all-costs phase, prioritizing market share and technological advancement over immediate profits. The S&P 500's decision serves as a reminder that traditional financial metrics still hold significant weight in the public markets, even as private valuations soar based on future potential.
What to watch next: This isn't a permanent ban, but it means these companies will need to demonstrate sustained profitability before they can join the S&P 500. For investors, it's a signal to look beyond the hype and consider the underlying financial health of these private tech giants. We'll be watching for any signs of these companies shifting their focus towards profitability, a move that would be necessary for eventual S&P 500 inclusion.
