Will Trump invoke the Insurrection Act?

The core reason this is not a low-probability event is that Trump has already placed the Insurrection Act in the policy conversation and shown a willingness to use other emergency authorities first. The Jan. 20, 2025 border emergency, the directive to report back on whether the Act should be invoked, and the use of alternative military-support authorities all suggest a real pathway exists if he decides ordinary law enforcement is inadequate or politically insufficient. Repeated later threats in other domestic contexts further increase the odds that this is not just rhetorical posturing.

Against that, the Insurrection Act is still a major escalation. It carries obvious legal, operational, and political risks, and history suggests presidents usually avoid it unless there is a clear, visible breakdown of civil order or a hard-to-manage enforcement crisis. Internal resistance matters too: prior Trump-era officials publicly opposed domestic troop deployment in protest contexts, which implies that even if Trump wants it, advisers may steer him toward narrower tools that achieve similar ends with less blowback.

Compared with the current market price of 20% yes, I think the market is a bit too skeptical. A 20% price implies invocation is a fairly remote tail event, but the combination of Trump’s prior behavior, his public threats, and the administration’s explicit planning makes this meaningfully more plausible than a generic low-frequency event. Still, 30% is not a strong yes; the most likely outcome remains no because the threshold for invocation is high and there are several easier alternatives he can use first.
