MW4 Open Matchmaking Explained: How Does It Actually Work?
MW4 Open Matchmaking is a separate playlist, called Open Moshpit in the beta, that barely factors in skill when it builds lobbies. It runs next to a default Quick Play queue that still uses skill. Here is what's confirmed, what isn't, and what Activision's own data says.
MW4 Open Matchmaking is a separate playlist type, called Open Moshpit in the beta, where skill is only "minimally considered" when lobbies are built. It runs alongside the default Quick Play queue, which still weighs your skill together with your connection and other factors. Activision has not confirmed whether Open playlists will be in the full game at launch on October 23. That's the short answer. The rest of this guide covers the details, the data and the caveats.
There is no SBMM on/off switch in the settings menu. You choose your lobbies by choosing a playlist. The other routes to softer matches are private matches against bots or a paid option like MW4 bot lobbiesfrom $4.99 for sessions spent purely on grinding. Each has trade-offs, which we cover below.
Quick-start checklist
- Read the playlist name. In the beta, only the tile labelled Open Moshpit used Open Matchmaking. Standard Quick Play did not.
- Know the mode pool. Open Moshpit carried just four modes: Team Deathmatch, Domination, Hardpoint and Kill Confirmed. It had no Search & Destroy and no Hardcore variant.
- Stop looking for a toggle. It doesn't exist.
- Expect swings. Open lobbies mean more one-sided matches, and you'll be on the losing end of some of them.
- Check the launch playlists on October 23. Nothing about Open's future is official yet.
MW4 Open Matchmaking Explained: The Two Systems
Verdict: there are two queues, and one of them turns skill weighting way down.
The setup is inherited from Black Ops 7. BO7 launched with Open playlists that Activision described as using only minimal skill consideration. Then in July 2026, with BO7 Season 5, Activision moved Quick Play, Black Ops Classic and Party Games onto a new system it says was "inspired by" the original Black Ops and Black Ops II. Its official pitch for that system covers smarter team balancing, a wide variety of matches, fewer half-empty lobbies and a better experience for parties with mixed skill levels.
The MW4 beta ran both systems side by side. Early Access was August 21–25 and the Open Beta was August 28 to September 1, extended to 10 PM PT. Activision said it kept Open available so it could learn from both.
| Quick Play (new system) | Open Moshpit (Open Matchmaking) | |
|---|---|---|
| Skill weighting | One factor among connection, location, platform and player population | Minimal |
| Beta modes | TDM, Dom, Hardpoint, KC, S&D, Inflation, Hijack | TDM, Dom, Hardpoint, KC |
| Match feel | Tuned for balanced, closer games | Wider skill spread, more blowouts both ways |
| Activision's position | Says data shows "strong improvements" | Kept as a comparison test |
| Launch status | Beta default; final launch setup not published | Unconfirmed |
Why Activision Isn't Making Open the Default
Verdict: Activision's own published numbers work against it.
On August 19, the official Call of Duty account posted BO7 data from launch through Season 4. It says that for 80% of players, Open lobbies compared with Standard showed:
- 32.7% higher quit rates
- 14.4% fewer kills per minute
- 5.3% lower win rates
- 59.2% more "Not Fun" ratings
Activision also says quit rates have fallen across every skill group since Season 5 began, by 41% for more than half of players. It also reports shorter search times and better average ping.
Those are Activision's figures and nobody has independently checked them. A community note on the post pointed to player-made benchmarks claiming search times had actually gone up. The reaction was loud: creators and players criticised the decision, and a Change.org petition asks for Open to become the default for casual 6v6.
The honest status as of September 30, 2026: Open Matchmaking existed in the MW4 beta, and nothing official says it will be there at launch. Anyone claiming either way is guessing.
One more thing worth knowing: some community voices noticed that the BO7 beta had several Open playlists, while the MW4 beta had exactly one. Many read that as a bad sign. It's a fair read, but it's still only a read. Infinity Ward also didn't mention matchmaking changes in its Weekend Two update, even though matchmaking was one of the biggest complaints from Early Access.
Does Open Mean No SBMM?
Verdict: no. Minimal skill weighting is still some skill weighting.
Activision has never said Open removes skill from matchmaking entirely. In Open, skill counts for much less, and the matchmaker accepts a much wider range of players into one lobby. That means some matches will feel like 2012 and some will feel like being dropped into a pro scrim. Meanwhile, the new default system is not the strict SBMM from Modern Warfare (2019) to MW3 either. Infinity Ward has said MW4 will not return to the pre-Black Ops 7 setup. The options aren't "sweaty vs. casual". They're "balanced but tuned" vs. "loose and random".
Related Questions
Can you turn off SBMM in MW4? No. MW4 has no in-game toggle for skill-based matchmaking. The closest you can get is picking a playlist, such as Open Moshpit if it ships at launch, or playing Private Matches against bots. Private Matches don't have the same progression value as public games.
Is Open Moshpit good for camo grinding? It's inconsistent. Open lobbies swing both ways, so you can't predict how much progress a session will get you, and the four-mode pool limits which challenges fit. If you want realistic time estimates for each mastery tier, our MW4 camo grind guide goes through them.
Do bot lobbies get around matchmaking entirely? Yes. A bot lobby never goes through public matchmaking, so SBMM isn't involved at all. Setups, limits and risks vary, and we cover them in MW4 bot lobbies explained.
Is the new default system better for parties? Activision says it gives parties with mixed skill levels a better experience than the old approach. That's the official claim. The only public evidence so far is the beta, and there player feedback was split.
The Bottom Line
Open Matchmaking in MW4 is real, it was tested in the beta, and its launch status is still unconfirmed. Queue Open Moshpit if it's there on October 23, and expect Quick Play to feel balanced rather than relaxed. Relying on playlist choice for a long weapon grind is a gamble either way. If you'd rather skip that gamble for grinding sessions, MW4 bot lobbiesfrom $4.99 are one option: no public queue and no SBMM, just steady progress.
