Her cryptic answer is not new, as ever since her Vogue announcement she has continued to drop similar indications she may one day return.
In August, she told US TV show Today, "You never know. I've learned in my career, never say never," when asked whether she will play another Grand Slam event. She has also pointed to Tom Brady's u-turn on retirement as starting an "amazing trend".
Williams remains one major title short of Margaret Court's overall record of 24, but said that her ambitions to expand her family had driven her "evolution" away from the court.
In reality, that evolution has been ongoing for the last year at least. The US Open was one of only four singles events Williams competed in in 2022, including Wimbledon where she crashed out in the first round.
Before that, she had spent almost a year out of competitive action due to injury and had turned her focus to numerous successful business ventures, including producing Oscar-winning film King Richard, based on her family's lives, and investing in women's football club Angel City.
When her longtime coach Patrick Mouratoglou left her camp in April, there had been mounting speculation around when her retirement would come, so her eventual goodbye in New York did not come as much of a shock.
If she were to return to the court, she would join sister Venus, 42, who remains sporadically active on the tour.
