Modern Warfare 4 SBMM: What We Know and What It Won’t Be

Modern Warfare 4 SBMM: What We Know and What It Won't Be

I walked into a sunlit conference room where creators were still arguing over one line from the demo: “Are you keeping SBMM?” You could feel the question ricochet between chairs. Developers answered carefully, and that pause told me more than their words.

I’m going to tell you what Infinity Ward said, what they didn’t say, and why the silence matters if you care about matchmaking. You’ve probably played through the SBMM fights before, so I’ll be direct: this is less about a full rollback and more about a course correction.

A developer scribbled notes while we asked about matchmaking.

They told us Infinity Ward is studying the data from Black Ops 7’s matchmaking system, and that’s the main headline. I’ve seen this movie before: when studios say they’re “analyzing data,” they’re deciding whether to follow player behavior or course-correct based on metrics.

Per CharlieIntel, the studio made one clear promise: they won’t simply revert to the pre-BO7 SBMM era. That’s meaningful. It means the extreme, hyper-focused matchmaking that made every match feel like a pressure test is unlikely to return.

What is SBMM?

SBMM, or skill-based matchmaking, pairs players by performance metrics so games feel even across teams. You know the effect: wins feel hollow, losses feel like personal calibration—like a scale balancing coins, where every play changes the weight.

Several creators nodded when “open matchmaking” came up.

Developers mentioned they like BO7’s approach. According to YouTuber Tdawgsmitty, Infinity Ward said they enjoy that matchmaking and “are not planning on changing it.”

Practically, that suggests MW4 will default to playlists that prioritize connection and broader pool matches—what many players call “open matchmaking.” But before you celebrate, remember BO7 still kept a “standard matchmaking” playlist that uses traditional SBMM.

Will MW4 use SBMM?

Short answer: yes and no. If Infinity Ward mirrors BO7, SBMM will exist in specific playlists, not as the default across the board. That split gives players a choice: match for fair competition or match for better latency.

This hybrid model behaves like a radio tuning between stations—sometimes you want pure clarity, sometimes a competitive frequency. Which one dominates will depend on the telemetry Activision and Infinity Ward prioritize.

The room wanted deadlines and clarity about release and transparency.

CharlieIntel also reported that Infinity Ward plans to be transparent about matchmaking before MW4 launches on Oct. 23. That’s a rare promise in our space, and it’s worth watching.

Here’s the reality you should prepare for: the final system will be data-driven. If the “standard matchmaking” playlist outperforms open playlists in retention, monetization, or player satisfaction, the default could shift. If open playlists prove healthier for engagement, SBMM will likely stay sidelined by default.

How will matchmaking work in MW4?

We don’t have the full blueprint yet. What we do have is a direction: no wholesale return to extreme SBMM, and an openness to keep BO7’s more permissive default. You’ll probably see multiple playlists, transparency about what each one does, and a final call based on live data.

I’m paying attention to the metrics that matter—playtime swings, queue times, and creator sentiment on platforms like X, YouTube, and Twitch—because those are the levers developers will watch. You should be too if you care about your preferred multiplayer experience.

So where does that leave you? Expect choice, expect a public explanation before launch, and expect a company still testing what players actually want—so which playlist will you be queuing up come Oct. 23?
