Texas officially joined the SEC on July 1, 2024.

Quick Scoop

  • The University of Texas Longhorns left the Big 12 and became a full SEC member starting July 1, 2024.
  • Oklahoma moved on the same timeline, so both Texas and OU entered the league together for the 2024–25 athletic year.
  • The original plan was for them to join in 2025, but an agreement between the Big 12, Texas, Oklahoma, and the SEC allowed an early exit to 2024.

How this unfolded

  • In 2021, Texas and Oklahoma requested and were granted SEC membership starting July 1, 2025.
  • Subsequent negotiations led to a revised deal so they could leave the Big 12 one year earlier, aligning their move with upcoming changes like expanded playoffs.

In short: if you’re asking “when does Texas join the SEC,” the answer is that Texas already joined as of July 1, 2024.

TL;DR: Texas joined the SEC on July 1, 2024, one year earlier than the originally targeted 2025 date.
