The bank was established on December 18, 1998, by a group of entrepreneurial bankers who were able to raise $80 million in start-up capital, the most for a new financial institution at that time.

[10][11] In October 2022, it expanded its lease at 2000 McKinney Avenue in Uptown Dallas for its headquarters, and the building was renamed Texas Capital Center.

[13] The bank primarily serves clients and operates full-service locations in Austin, Dallas, Fort Worth, Houston, and San Antonio metropolitan areas of Texas.

During this time, Archegos was in communication with Texas Capital management about its rising stake, including with Jody Grant, who founded the Bank in 1998.

Grant's discussions with Hwang's family office were friendly, and it appears Archegos were supportive of Texas Capital Bank's management.

As the stock price rose towards a 2 year high around March 2021, Texas Capital decided to issue 12,000,000 new shares for an aggregate sum of $300 million.
