Texas Stock Exchange begins operations with test trades, live trading set for Friday

The Texas Stock Exchange officially started operating on July 6, 2026, running test trades through approved broker-dealers, banks, and trading firms. Live trading in a limited set of securities is scheduled to begin on July 10.

The US hasn’t seen a fully integrated national securities exchange get SEC approval in decades. TXSE just did it, and now it’s actually turning on the lights. The exchange, headquartered in Dallas and founded by CEO James H. Lee, is positioning itself as a genuine alternative to the New York-centric financial establishment.

How the rollout works

TXSE is taking a crawl-before-you-sprint approach. The test trades conducted on July 6 involved designated symbols, letting member firms verify their systems and connectivity before real money starts flowing.

The exchange supports trading in equities, exchange-traded products and ETFs, and American Depositary Receipts. Corporate listings are expected to begin in Q4 2026.

TXSE is part of both the UTP and CTA plans, the industry data-sharing frameworks that ensure quotes and trades from different exchanges are consolidated into the national market system. That integration means TXSE-traded securities will show up in the same data feeds that investors and brokers already use.

Breaking a decades-long monopoly structure

The SEC approved TXSE’s Form 1 registration on September 30, 2025. That approval made it the first fully integrated national securities exchange to get the regulatory green light in a generation.

There are technically around 16 registered stock exchanges in the US. But the overwhelming majority of corporate listings and public attention flow to just two: the New York Stock Exchange and Nasdaq.

What this means for investors and markets

For retail investors, the immediate impact is close to zero. Behind the scenes, though, your broker’s routing algorithms may start sending some orders to TXSE if the exchange offers better prices or faster execution.

If TXSE can attract corporate listings starting in Q4 2026, it could fundamentally alter the economics of going public. NYSE and Nasdaq charge listing fees, and a credible third option changes that calculus.

New exchanges face a chicken-and-egg problem: traders go where the volume is, and volume goes where the traders are. TXSE’s strategy of starting with NMS securities that already trade on other exchanges is designed to sidestep this problem initially, since market makers can arbitrage prices across venues.

The exchange doesn’t need to match NYSE’s roughly 25% market share overnight. Even capturing a few percentage points of daily US equity trading volume would represent a meaningful reshuffling of the competitive landscape.
