The launch of Call of Duty: Modern Warfare 4 successfully lifted player engagement across ecosystems, according to new figures from Circana's Mat Piscatella. Data covering the week ending October 24, 2026, shows that the shooter climbed to 3rd place on Xbox worldwide player standings, leapfrogging NBA 2K27.

Quick Facts

  • Platforms: Xbox Series X|S, PlayStation 4, PlayStation 5, Steam
  • Data Source: Circana Player Engagement Tracker (Top 10 Titles by Weekly Active Users)
  • Key Date: Week ending October 24, 2026 (Modern Warfare 4 launch week)

Platform Performance Breakdown

Circana tracks games based on weekly active users rather than concurrent players. On Sony hardware, Call of Duty climbed two places to capture the 2nd spot in the weekly active user rankings. Meanwhile, Steam's US charts saw the most dramatic movement for the franchise, with Call of Duty rocketing from 32nd place up to 6th following the release.

Despite the post-launch surge, Modern Warfare 4's overall ecosystem impact fell short of the numbers recorded during the launch of Call of Duty: Black Ops 7 in late 2025. During Black Ops 7's opening week (ending November 15, 2025), Call of Duty made up 23% of active US PlayStation players, 29% of worldwide Xbox players, and 1.5% of US Steam players.

By comparison, Modern Warfare 4's launch week figures reached 19% on US PlayStation, 17% on worldwide Xbox, and 4.2% on US Steam.

Why the Difference in Player Impact?

Circana's data highlights a lower percentage of active players on Xbox during the Modern Warfare 4 launch window compared to the previous year. Two primary factors explain the shift: Black Ops 7 launched as a day-one title on Xbox Game Pass in 2025, providing a significantly larger initial player pool to draw from. Additionally, Modern Warfare 4 utilized a staggered release schedule, offering early access to campaign and DMZ modes prior to the full game launch on October 23, 2026.
