S&P Dow Jones Indices Expands Eligible Exchanges List

On May 27, 2026, S&P Dow Jones Indices (often referred to as S&P DJI) announced significant updates to its methodology regarding the list of eligible exchanges for the S&P U.S. Indices. The most noteworthy addition is the Texas Stock Exchange (TXSE), which is set to commence continuous trading on July 6, 2026.

This move is primarily driven by the goal of accurately measuring the market performance of stocks that are both U.S.-domiciled and trading on U.S. exchanges. With the integration of TXSE, the S&P U.S. Indices will now include stocks listed on this exchange alongside the previously established exchanges. This is expected to contribute positively to the overall landscape of U.S. equities, although initially, no immediate impact on the indices is anticipated.

Methodology Overview

The S&P U.S. Indices aim to reflect the performance of the U.S. equity market, and to achieve this, they have specific criteria that mirror the sectors and stocks traded across various platforms. Under the updated methodology, the eligibility criteria will now acknowledge listings on both traditional exchanges and TXSE.

Previous Criteria:

• - Must be listed on one of the following:

- NYSE
- NYSE Arca
- NYSE American
- Nasdaq Global Select Market
- Nasdaq Global Market
- Nasdaq Capital Market
- Cboe BZX
- Cboe BYX
- Cboe EDGA
- Cboe EDGX

Updated Criteria:

• - Must be listed on one of the following including the new addition:

- NYSE
- NYSE Arca
- NYSE American
- Nasdaq Global Select Market
- Nasdaq Global Market
- Nasdaq Capital Market
- Cboe BZX

- Texas Stock Exchange (TXSE)

Impacted Indices

The expansion will directly affect several key indices, including:

• - S&P 500
• - S&P MidCap 400
• - S&P SmallCap 600
• - S&P Composite 1500
• - S&P Total Market Index
• - S&P Completion Index

This update will also be applicable to indices that derive their framework from these main indices, impacting a wide range of size, sector, style, factor, and sustainability indices. Stakeholders and investors should refer to individual index methodologies for more detailed information.

Looking Forward

As Texas Stock Exchange prepares for its launch, S&P DJI is keen on ensuring that the indices remain robust and representative of market trends. The effectiveness of this change will take place automatically with the commencement of TXSE's continuous trading.

For those interested in further details or updates, the S&P U.S. Indices Methodology is readily accessible on the S&P DJI website, where all procedural changes and criteria will be distinctly outlined. For those wanting a comprehensive view of market trends and financial metrics, the S&P U.S. Indices remain a prime resource.

With the addition of TXSE, the S&P U.S. Indices evolve to better capture the dynamics of the American equity marketplace. Stakeholders are encouraged to keep abreast of further announcements as this transition approaches.
