The Xbox One outsold the PlayStation 4 during September, according to a games analyst.
Michael Pachter estimates that Microsoft sold 325,000 new Xbox Ones at U.S. retailers last month, while Sony sold 250,000 PS4s.
If accurate, it would be the second time the Xbox One has achieved more sales over its main rival since the two consoles launched in November 2014.
According to Pachter, the feat is largely down to a Microsoft promotion offering a free game with the purchase of a new Xbox One console during the week in which Destiny was released.
Industry-tracking firm The NPD Group will reveal the official sales data for September later this month.
