Overview
- Trump wrote on Truth Social that building a New York Stock Exchange presence in Dallas is “unbelievably bad” for New York and a “big test” for Mayor Zohran Mamdani.
- NYSE Texas operates out of Dallas as a fully electronic market that evolved from the former Chicago Stock Exchange and began trading in 2025, attracting several dual listings.
- Intercontinental Exchange and the NYSE say the move is meant to broaden their footprint to serve companies in the South and Southwest rather than replace New York operations.
- Oversight of U.S. stock exchanges rests with the Securities and Exchange Commission, meaning New York City’s mayor has no authority over the expansion.
- Dallas Mayor Eric Johnson welcomed the development, and ICE notes Texas hosts more NYSE-listed companies than any other state, representing over $3.7 trillion in market value.
