Tommy Haas, director of the combined ATP and WTA event, called it an "honour" to offer the first wildcard invitation of 2026 to the US tennis icon, who received entry to both singles and doubles and is scheduled to appear in the California desert for the first time since 2024.
“I’m so excited to be heading back to Indian Wells and can’t wait to return home to play in California," Williams said in a statement.
"I’m grateful to the tournament for having me back and giving me the opportunity to compete in both singles and doubles."
In January, Williams made history as the oldest woman ever to play at the Australian Open, accepting a wildcard invitation and pushing 24-year-old Serbian Olga Danilovic all the way before falling in three sets in the first round.
Williams has played only sporadically in recent years. She returned from a 16-month hiatus at the DC Open last July.
