PlayStation 5 shipments have begun to ramp up this year. Sony nearly hit 40 million consoles sold earlier this year and tripled the number of consoles it shipped from January to March 2023 at 6.3 million units. At the same time last year, it shipped just 2 million PlayStation 5 consoles.
For comparison, best I could find is Xbox Series X|S selling 21M units. Link. This means Sony outpacing Xbox by a 2:1 ratio, or market share is 66% vs. 33%.
