- S&P Dow Jones Indices conducted a consultation on potential changes to methodology for MegaCap companies but decided to keep eligibility criteria unchanged for S&P 500, S&P MidCap 400, and S&P SmallCap 600.
- No exceptions will be granted to financial viability, seasoning, or minimum Investable Weight Factor requirements based solely on market capitalization to preserve core index principles.
- Changes will be implemented for S&P Total Market Index, S&P Completion Index, and Dow Jones U.S. Total Stock Market Index, including updated Investable Weight Factor rules and IPO fast-track eligibility.
- Float increases after IPO lock-up periods may be implemented gradually at the Index Committee's discretion to reduce market impact and support replicability.
- Methodology changes for the broad market indices will take effect prior to market open on Monday, June 8, 2026.
