Summary

On-chain analysis suggests that SpaceX and other mega IPOs could weigh on U.S. stock performance for years. Rob Arnott of Research Affiliates noted that these listings may drain hundreds of billions from existing stocks. The dilution effect could persist as index inclusion lags. On-chain data shows market shifts as new listings gain traction. Arnott emphasized that the drag will continue as these firms gradually enter major indices.

ME AI message, Rob Arnott, founder of Research Affiliates, stated that mega-IPOs such as SpaceX, Anthropic PBC, and OpenAI could exert a multi-year drag on the broader stock market by diverting hundreds of billions of dollars away from existing equities. This diversion effect may take time to materialize after S&P Dow Jones Indices decided not to rapidly include these large new listings in their indexes. However, according to Arnott, the impact would naturally take longer to spread through the market as these companies gradually gain weight in the indexes. Arnott, a pioneer in smart beta investing whose firm’s strategies are adopted by institutions such as Pimco and Invesco, said: “This will disrupt capital markets, and it already is disrupting capital markets.” He is known for his research on fundamental indexing, an approach that determines index component weights based on metrics such as earnings and cash flow.
