Will Trump invoke the Insurrection Act?
Trump invoking the Insurrection Act is plausible but still a low-probability event. I estimate a meaningfully higher chance than the market, around 26%, because his public posture and incentives make a domestic-emergency invocation more likely than for a typical president.
Analysis
The baseline against a Yes outcome is strong: the Insurrection Act is an extraordinary legal tool, and presidents usually avoid it because it is politically explosive, legally contested, and often unnecessary when other federal authorities or state actions can address unrest. The fact that the event window extends through a full presidential term matters, though, because the probability accumulates over time; even a low annual chance can become nontrivial across several years. Trump’s prior behavior suggests he is more willing than most presidents to consider aggressive domestic enforcement measures, particularly if he frames a situation as lawlessness, border-related chaos, or a breakdown of local control.
Arguments for Yes are driven by incentive structure rather than routine governance. Trump has repeatedly signaled interest in using the military or federal force more expansively at home, and the Insurrection Act is one of the few legal pathways that could align with that instinct. A major protest wave, widespread civil disorder, clashes around immigration enforcement, or a politically salient security crisis could all create a moment where invoking the Act looks attractive to him as both a power tool and a symbolic demonstration of authority.
Arguments against Yes remain substantial because invoking the Act would trigger intense institutional resistance, litigation, and likely political backlash even from some allies. Trump can often achieve much of the same rhetorical effect by threatening action, deploying National Guard forces through other channels, or leaning on existing federal law without crossing the threshold into an Insurrection Act declaration. That makes the true decision point dependent on a serious crisis, not just hardline rhetoric, and such crises are uncertain. Still, compared with the current market price of 18%, I think the market is a bit too dismissive of the tail risk created by Trump’s style, past statements, and the long horizon available for an unexpected domestic emergency to occur.
Arguments
For
- Trump has strong incentives to frame domestic disorder as an emergency warranting extraordinary measures.
- A single major protest, immigration, or public-order crisis could be enough to make invocation politically attractive.
Against
- Presidents rarely invoke the Insurrection Act because the legal and political blowback is severe.
- Trump may prefer to threaten extraordinary action without actually crossing the invocation threshold.
Key drivers
- Trump has a demonstrated preference for forceful domestic authority and may be more willing than prior presidents to test the limits of executive power.
- The long time horizon through 2029 increases the cumulative chance that a qualifying crisis or unrest event will occur.
Risk factors
- The Insurrection Act is politically and legally costly, making it more likely Trump chooses less extreme alternatives first.
- Many potential unrest scenarios can be managed with National Guard deployments, federal law enforcement, or emergency rhetoric without invoking the Act.
Scenarios
Best case
A large-scale domestic unrest or border-related crisis gives Trump a clear pretext, and he formally invokes the Insurrection Act as part of a broad federal response.
Most likely
Trump repeatedly signals willingness to use the Act, but the presidency never reaches the combination of crisis, legality, and political calculation needed to actually invoke it.
Worst case
No sufficiently severe crisis emerges, and Trump relies on alternative tools such as National Guard activation, federal law enforcement, or aggressive rhetoric instead.

When will Greg Schiano leave Rutgers?
AI28%MKT93%Edge-65HypedI think Greg Schiano is much more likely to remain Rutgers coach through Feb. 1, 2027 than the market suggests. The current record has created pressure, but there is no concrete departure signal yet, and the price appears to be extrapolating hot-seat chatter far beyond the evidence.

Will 3 mg THC beverages qualify as hemp under federal law?
AI28%MKT92%Edge-64HypedMy estimate is that 3 mg THC beverages will probably not qualify as hemp under federal law on Nov. 13, 2026. The reported container-based THC cap is far below 3 mg, and the main uncertainty is timing rather than substance.

How many more Millennium Prize Problems will AI solve in 2026?
AI28%MKT69%Edge-41HypedI think there is a low chance that AI ends 2026 having solved zero additional Millennium Prize Problems, because there is already a public claim from an eligible lab that it solved Navier-Stokes. The main uncertainty is whether that claim ultimately counts under the market’s exact wording, but absent a major reversal, the zero-outcome looks weaker than the market price implies.
