Leadership marked the milestone in Dallas with a bell ceremony at TXSE headquartersDALLAS, July 31, 2026 — The Texas Stock Exchange commemorated the successful launch of production trading with a bell ceremony at its Dallas headquarters, marking the completion of a phased rollout of all National Market System symbols on its platform. In just 18 months, TXSE built a custom order-matching engine and delivered a fully integrated exchange — trading and listings together — something no prior entrant has done. With more than 50 member firms, TXSE opens full production trading with the broadest day-one participation of any exchange launch in a half century. Today’s milestone sets up the exchange to introduce auctions to support listings later this year and bring to market innovative new trading solutions.
