Will Trump invoke the Insurrection Act?
I assess a roughly one-in-three chance that President Trump will invoke the Insurrection Act by Jan 1, 2027 — plausible given low statutory triggers and a DOJ unlikely to block him, but constrained by high political, legal, and institutional costs.
Analysis
**Stage 1 — Blind analysis (ignore market prices):**
The statutory test to invoke the Insurrection Act is *broad* and fact-specific: a governor request, an insurrection against state government, or circumstances that make enforcement of federal law impracticable. Experts describe those triggers as "fairly soft," and historically the Act has not been litigated to a definitive Supreme Court resolution on many of its edges. Practically, therefore, the legal bar is not insurmountable if the White House and DOJ decide to treat a given set of events as satisfying the statute.
Empirically, the Trump administration has shown a willingness to use military forces domestically: deployments to California and to D.C.-area streets occurred without formal Insurrection Act invocation, and litigation (Newsom v. Trump and Judge Breyer's injunction) demonstrates both the White House's willingness and the judicial willingness to push back. The key change since 2020 is institutional alignment: the Department of Justice under this administration appears less likely to oppose invocation, removing one major check that stopped a prior administration. That materially raises the plausibility that the president would choose the Act when politically expedient.
However, strong countervailing forces remain. Invoking the Act is an escalatory, highly visible constitutional move that invites immediate litigation, political condemnation, and possibly institutional resistance from military and state actors. Governors—especially those of large states like California—are unlikely to request federalization except under extreme circumstances; and if a governor refuses, invoking the Act without that request (or on the §252/§253 theories) produces a much stiffer political and legal fight. Military leaders historically resist orders that they judge unlawful or that would degrade military apolitical norms; that resistance could be decisive. Finally, the most plausible trigger window in the short run is the 2026 midterms (November 2026), where election-related unrest is conceivable but not inevitable.
Balancing these elements, I judge invocation by Jan 1, 2027 to be plausible but not the most likely outcome. The combination of lower institutional obstacles (DOJ alignment, prior domestic deployments) pushes probability up; the political, legal, and practical costs push it down. My independent, blind estimate: 30%.
**Stage 2 — Market calibration (look at market prices):**
Current market: Yes 21%, No 79%. My independent estimate (30%) is meaningfully higher than the market price. Possible reasons for the market's lower probability:
- Market participants may overweight the political costs and potential backlash while underweighting the changed institutional landscape (notably DOJ alignment and prior non-Act deployments as a behavioral precedent). - Traders may be anchoring to 2020 experience when DOJ resisted and DoD leadership pushed back, assuming similar brakes remain in place; if they underappreciate turnover in senior DOJ/DoD personnel and differing incentives, they underprice the chance. - Liquidity and crowd psychology: given the binary, visceral nature of invocation, markets might be risk-averse and discount low-probability/high-impact political shocks (like sudden outbreaks of intense, state-level unrest that could justify invocation).
Alternatively, the market may be correctly discounting practical realities I emphasized: governors' reluctance to request federal troops, the real possibility of rapid injunctive relief from courts, and the military's informal institutional constraints. Those countervailing forces are powerful and could justify a lower market probability.
Net calibration: the market appears to underweight the administration's ability and willingness to frame events to meet the Act's triggers, but it may correctly price the high costs and resistance that make invocation a nontrivial gamble. I therefore view the market as somewhat conservative; the gap (30% vs 21%) reflects my assessment that DOJ alignment and behavioral precedent elevate the chance modestly above market-implied odds.
Arguments
For
- The statutory triggers in the Insurrection Act are broad and fact-dependent — prosecutors and the White House could plausibly interpret electoral violence, large-scale riots, or obstruction of federal laws as meeting the test.
- This administration has already deployed forces domestically without using the Act, showing a willingness to use military options; that behavioral precedent makes formal invocation more credible if conditions escalate.
- DOJ in the current administration is less likely to oppose invocation compared with 2020, removing a major internal check and increasing practical likelihood if the White House desires it.
- Midterm elections create a predictable risk window (Nov 2026) when localized violence or claims of lawlessness could be framed as justifying an Insurrection Act response.
Against
- Invoking the Act is a highly escalatory, politically explosive move that would trigger near-immediate nationwide condemnation, litigation, and potential mobilization against the administration — a strong deterrent.
- Governors (especially from opposition parties) are unlikely to request federal troops; invoking the Act without a request under §252/§253 is far more legally and politically fraught.
- Judicial remedies (temporary restraining orders, injunctions) are likely to be rapid and could block deployments, reducing utility and increasing costs to the president.
- The U.S. military and senior DoD officials historically resist orders they view as politically dangerous or unlawful; even with compliant civilian leadership, practical execution could be delayed or limited.
Key drivers
- Occurrence and intensity of large-scale civil unrest or violence in a U.S. state (particularly around November 2026 midterms)
- Whether a state governor or legislature requests federal military assistance under §251
- Department of Justice stance and willingness to endorse presidential invocation
- U.S. military/DoD operational and legal willingness to carry out domestic orders
Risk factors
- Immediate legal injunctions and court rulings (Posse Comitatus/constitutional challenges) that could block or reverse invocation
- Refusal or public pushback from state governors, eroding any pretext for invocation and provoking political backlash
- Institutional resistance inside the military or DoD leadership that slows or prevents effective execution
- Severe domestic political fallout that damages the presidency and complicates subsequent governance or electoral prospects
Scenarios
Best case
A state experiences intense, organized violent unrest that either overwhelms state capacity or leads the governor to request federal assistance. The White House and DOJ quickly conclude statutory conditions are met, the president invokes the Insurrection Act, DoD executes the order with limited delay, federal troops restore order, and courts either decline to enjoin or litigation is slow enough that the deployment achieves its immediate objectives.
Most likely
Through Jan 1, 2027, there are threats, planning, and public discussions of invoking the Act — including executive orders, contingency planning, or threats to federalize forces — but no formal, sustained invocation. The administration uses other levers (federalizing the National Guard under mutual-aid compacts, DOJ interventions, federal law enforcement deployments) instead of invoking the Insurrection Act.
Worst case
The president attempts invocation absent a governor's request or on a tenuous legal theory; state officials sue immediately, federal judges issue injunctions within days, national media and political opponents mount massive challenges, key military leaders publicly resist, and the administration suffers heavy political and operational losses — the deployment is blocked and the presidency is weakened.

What will the average number of measles cases be during Trump's term?
AI72%MKT28%Edge+44Hidden GemI assess a 72% independent probability that the average annual number of US measles cases across 2025–2028 will meet or exceed ~3,000 per year (i.e., the 'Yes' outcome). This reflects the strong acceleration in 2026, weak policy response, and high-risk pockets that make a sustained multi-year elevated average more likely than not.
