Resolution criteria
The Mann vs. Machine update was teased to arrive on or around August 27, with a second installment timed for release around October 31st. This market resolves YES when Valve officially adds community-made maps to MvM for the first time since 2013. Resolution will be verified via the official TF2 blog or Steam patch notes.
Background
Valve is planning a new Team Fortress 2 Mann vs. Machine update, more than a decade after the co-op game mode came to the team-based shooter, and is asking TF2's community to make and submit maps and missions. The update to the Mann vs. Machine mode is being split into two parts, with the first half likely including bug fixes and general adjustments to the game mode. As of September 2025, Valve stated they don't have a release date for the update yet but are going through the submissions and working on it.
Considerations
The last major update is generally thought of as 2017's Jungle Inferno, making this Mann vs. Machine update particularly significant after an 8-year gap. Valve is taking an unprecedented approach by actively soliciting community contributions, with a deadline set for Wednesday, August 27th.

1,000For the March–June 2026 outcomes: Valve’s July 16 update says the MvM update was still in development. I also checked the official March 6, March 11, May 22 and May 25 patch notes; none added community MvM maps, and the official archive lists no April or June release. A Scout sound fix is not a map addition under this market’s criterion.

Disclosure: M50 NO on each of March, April, May and June (M200 total). These elapsed outcomes appear to be NO, though I understand settlement may wait for the overall market.
