Quick answer
- MW4 Steam player count right now: 70,518 concurrent players on Steam app 1938090, sampled 2026-10-20 14:30 UTC. This app covers the combined Call of Duty Steam install, including Warzone, so it is an upper bound for MW4 alone.
- MW4 Steam 24-hour peak: 75,855 players. Currently 93% of that peak.
- MW4 Steam 7-day average: 68,692 players over 2026-10-16 15:00 UTC → 2026-10-20 14:00 UTC (a 4-day window, not a full week of complete days).
- MW4 Twitch viewers right now: 44,588 viewers across 533 live channels, sampled 2026-10-20 14:30 UTC. 24-hour Twitch peak: 44,588.
- MW4 across PC, PlayStation and Xbox: no official total exists. Steam is the only platform with a public concurrent count; console counts are not published.

What the Steam figure actually measures
Steam app 1938090 is the combined Call of Duty Steam application. It covers Modern Warfare 4 but also Warzone and other Call of Duty titles and modes that ship under the same app, so the figure is an upper bound for MW4 alone, not an MW4-only count.
Twitch viewers are viewers: people watching streams in the Modern Warfare 4 category. They are not players and Twitch category metrics do not measure total active players.
Trend
Is the MW4 player count rising or falling?
Week over week, complete days only
Across the 3 complete UTC days in this sample (2026-10-17 → 2026-10-19), the daily Steam average moved from 85,952 to 56,657: -29,295 (-34.1%), a decline.
Method: average every 15-minute sample inside each UTC day, keep only days with at least 90% of the expected hourly points and exclude today, then compare the first and last complete day.
Daily average and peak (UTC)

| 2026-10-20 | 49,808 | 70,518 | partial (15) |
Partial days are shown but never compared: they hold fewer samples than a full day because tracking started mid-day or the day is still running.

Steam players vs Twitch viewers
Over 2026-10-13 14:00 UTC → 2026-10-20 14:00 UTC there were about 18 Twitch viewers per 100 Steam concurrent players. The 24-hour average was 20,219 viewers against 68,692 average Steam players on the 7-day window.
This is an attention ratio. Viewers are people watching a stream; players are concurrent game sessions in a combined Call of Duty app. The two numbers are never added together on this page.
Twitch by hour (UTC, 7 days)
Busiest window averages 21,576 viewers around 19:00 UTC; quietest averages 4,188 around 07:00 UTC.
Twitch viewers are viewers: people watching streams in the Modern Warfare 4 category. They are not players and Twitch category metrics do not measure total active players.

Methodology
Where these MW4 numbers come from
How the data is collected
- A GitHub Action calls the public Steam player API for app 1938090 and the Twitch category API for Call of Duty: Modern Warfare 4 every 15 minutes.
- Each run writes src/data/live/population.json, commits it, and rebuilds this static site, so every figure here is in the crawlable HTML rather than drawn by JavaScript.
- Steam 24-hour peak is the maximum sampled value in the trailing 24 hours. The 7-day average is the mean of the hourly series that the collector downsamples for the daily tables.
- A UTC day is labelled partial when it has fewer than 90% of the expected 15-minute samples, and partial days are excluded from the week-over-week comparison.
- If the collector fails, population.json keeps the last successful timestamp and this page prints it, flags the data as stale, and refuses to call it live.

Sources you can check yourself
- Steam app 1938090 on SteamDB — Independent third party; shows the same combined Call of Duty app.
- Steam store page for app 1938090 — First-party listing for the combined app.
- Twitch directory: Call of Duty: Modern Warfare 4 — First-party category the viewer count is sampled from.
- Activision newsroom — No player-count reports have been published here for MW4.
API limits: the Steam player endpoint reports a single global concurrent count for one app, with no platform breakdown. The Twitch endpoint reports category viewers and live channels only. Neither is an official publisher statistic.
Questions
MW4 player count questions
- How many people are playing MW4 right now?
- The latest sample, taken 2026-10-20 14:30 UTC, shows 70,518 concurrent players on Steam app 1938090 and 44,588 viewers on Twitch. Steam counts the combined Call of Duty install, so the real MW4-only number is lower; console players are not counted at all.
- What is the current MW4 player count on Steam?
- 70,518 concurrent players, sampled 2026-10-20 14:30 UTC. The 24-hour peak is 75,855 and the 7-day average is 68,692 over 2026-10-16 15:00 UTC → 2026-10-20 14:00 UTC. Steam app 1938090 is the combined Call of Duty app, so it also includes Warzone and other Call of Duty titles and modes.
- How many people are watching MW4 on Twitch right now?
- 44,588 viewers across 533 live channels, sampled 2026-10-20 14:30 UTC. The 24-hour Twitch peak was 44,588 and the sampled all-time peak is 232,790. Viewers are not players.
- What is the 24-hour peak player count for MW4?
- 75,855 concurrent players on Steam in the trailing 24 hours, taken from 15-minute samples of app 1938090. On Twitch the 24-hour viewer peak is 44,588.
- Is MW4 player count going up or down this week?
- Down or up depends on the window you use, so here is the raw comparison. Across the 3 complete UTC days in this sample (2026-10-17 → 2026-10-19), the daily average went from 85,952 to 56,657, a change of -29,295 (-34.1%). That is a decline.
- What is the average MW4 Steam player count over the last 7 days?
- 68,692 players, averaged over 2026-10-16 15:00 UTC → 2026-10-20 14:00 UTC. That window is 4 days long because sampling started when the tracker went live, so it should be read as a rolling figure that becomes a true 7-day average once a week of data exists.
- How many people play MW4 across PC, PlayStation and Xbox?
- No official cross-platform total exists. Activision does not publish Xbox, PlayStation, Battle.net or Switch player counts, and no first-party API exposes them. Steam concurrency (70,518 at 2026-10-20 14:30 UTC) and Twitch viewership (44,588 viewers) are the only public measurements on this page.
- Where can I find a live MW4 player count tracker?
- This page is one: it samples Steam app 1938090 and the Twitch Modern Warfare 4 category every 15 minutes and publishes the numbers in the HTML. For a Steam-only second opinion, SteamDB's chart for app 1938090 shows the same combined application.
- What are the most reliable sources for MW4 population statistics?
- First-party: Activision has published no MW4 player counts. Directly measurable: the Steam Web API for app 1938090 and the Twitch category API. SteamDB reports the same Steam app. Console and Battle.net counts have no public source, so any figure claiming a cross-platform total is an estimate.
- How does MW4 Twitch viewership compare with its Steam player count?
- Over the last 7 days there have been about 18 Twitch viewers per 100 Steam concurrent players. Viewers are not players and Twitch counts only people watching streams in the Modern Warfare 4 category, so the ratio describes attention, not the player base.
