Will Trump invoke the Insurrection Act?
I estimate a meaningfully higher-than-market chance that Trump invokes the Insurrection Act at some point in his presidency, mainly because he has both the incentive and the rhetorical willingness to use domestic military powers in a crisis. Still, this remains an uncommon and politically fraught step, so the probability is well below a coin flip.
Analysis
Trump is one of the few modern presidents who has repeatedly signaled comfort with using extraordinary domestic force, and the Insurrection Act is the clearest legal tool for that kind of move. Over a multi-year horizon, the odds of a trigger event are not trivial: large-scale civil unrest, a border-related emergency, election-related disorder, or a serious security breakdown could all create conditions where he would view invocation as useful or even politically advantageous. The key point is that this is not just a question of abstract willingness; it is a question of whether a sufficiently disruptive event appears before the end of his term, and that risk is substantial over several years.
The main reasons to stay below 50% are that invoking the Act is still an extreme step with real institutional friction. It would almost certainly trigger lawsuits, congressional backlash, and resistance from parts of the Pentagon or Justice Department if the factual predicate looked weak. Trump also did not invoke it in 2020, despite intense unrest and pressure from advisers, which shows that even for him the political and operational hurdles are real. Many situations that might motivate him can instead be handled through National Guard deployments, federal law enforcement, or emergency powers short of the Insurrection Act.
Compared with the current market price of 20%, I think the market is somewhat too low if the question truly spans the full presidency through January 2029. A 32% estimate still respects how rare formal invocation is, but it gives more weight to Trump-specific behavior and the longer time window, both of which increase cumulative odds. The market looks more defensible only if traders are implicitly pricing a shorter effective horizon or assuming that political and legal guardrails will keep him from crossing the line.
Arguments
For
- Trump has repeatedly framed domestic unrest, immigration, and law-and-order issues in apocalyptic terms that make extraordinary measures more plausible.
- A serious protest wave, election disorder, or border emergency during his term could provide the kind of catalyst that turns rhetoric into action.
Against
- The Insurrection Act is a drastic and historically rare measure, so the default outcome is still no invocation.
- Trump passed on using it in 2020, suggesting that even when he is tempted, practical and institutional barriers can stop him.
Key drivers
- Trump has a demonstrated preference for using aggressive executive authority in domestic security situations.
- A multi-year presidency creates a non-trivial chance of a crisis severe enough to make invocation politically attractive.
- The Insurrection Act is broad enough that a determined president can find a plausible justification if unrest is widespread.
Risk factors
- Invocation would generate major political, legal, and military pushback that could deter even a willing president.
- Trump may prefer other tools, such as federal law enforcement or National Guard deployments, that achieve similar aims with less escalation.
Scenarios
Best case
A major domestic crisis erupts and Trump concludes that only a formal Insurrection Act invocation can restore order, making the answer Yes.
Most likely
Trump continues to threaten or discuss extraordinary domestic force, but the crisis threshold is never quite met, or he uses other authorities instead of formally invoking the Insurrection Act.
Worst case
No sufficiently severe unrest occurs, or advisers and institutions steer him toward less controversial options, so the Act is never invoked.

"Spider-Man: Brand New Day" total domestic gross by August 31? (Higher Strikes)
AI25%MKT84%Edge-59HypedMy read is that Spider-Man: Brand New Day is more likely to finish above 900M domestically by August 31 than below it. I put the chance of less than 900M at about 25%, because the film is already so far along that only an unusually sharp slowdown would keep it under the line.
