This market resolves Yes if the Trump administration deploys any military assets such as the National Guard or the Marine Corps to the city of Baltimore, Maryland before November 4th 2026. Although there is no legal process for federalizing the police outside of Washington, DC, if the Trump administration for example successfully commandeers the Baltimore PD, this will also be considered sufficient for a Yes as the spirit of the market is about armed federal takeovers of US cities.

Normal logistical movement of the military throughout the country does not count. Active service members must be in the streets, on camera, or otherwise uncontroversially described by a major news outlet as deployed in Baltimore in excess of what is normal, ie. a small military presence at a major airport on Christmas in line with past Homeland Security activity would not be sufficient.

It is likely that Trump will be loudly and clearly declaring any such actions, so this market will probably have a clear resolution. Feel free to ask clarifying questions in the comments.
