The Texas Stallion Stakes Series features four sets of races, each split into two divisions (colts/geldings and fillies) for a purse of $125,000 per division. Each division has been named after a great Texas horse of the past.

The Stallion Stakes schedule begins in July with the Staunch Avenger and Pan Zareta divisions for 2-year-olds, going 5 1/2 furlongs at Lone Star Park. The next race in the series is at Retama Park in the fall, with the My Dandy and Darby's Daughter divisions at six furlongs. In January or February, 3-year-olds compete in the Jim's Oribt and Two Altazano divisions at one mile at Sam Houston Race Park. The series concludes at Lone Star Park with the Stymie and Got Koko divisions at 1 1/16 miles.

Eligible foals must be nominated to the Stallion Stakes to participate. Foal owners can nominate for $100 by December 31 of the weanling year, or $500 by December 31 of the yearling year. After that, there is no other opportunity to nominate. Once nominated, the foal is eligible to run in all four stakes in the Series for a $500 entry and $1,000 start fee per race. There are no late nominations, supplemental entries or sustaining payments.
