How much will US democracy weaken under Trump?

**Stage 1 — Blind analysis (ignore market price):**

The Economist Intelligence Unit (EIU) Democracy Index is a composite of five subindices (electoral process and pluralism; functioning of government; political participation; political culture; civil liberties). Historically the U.S. has been in the high 7s/low 8s; falling under 7.60 within a 3–4 year window requires either concentrated, large declines in one or two subindices or smaller declines across multiple categories. Given the recent documented spike in policy uncertainty after January 2025 and sustained elevated volatility into 2026, there is a plausible pathway for measurable erosion — most notably in "functioning of government" and "civil liberties" — but not an automatic or inevitable slide.

Arguments that make a drop below 7.60 plausible include: aggressive executive actions that undermine independent institutions (e.g., politicized removals, curbs on administrative independence), repeated delegitimization of electoral opponents and election officials, legal and regulatory actions that restrict press freedom or protests, and synchronized policy shocks that lower perceived government effectiveness. The 2025 uncertainty spike (index ~495 in January 2025) and later elevated readings around 395 by March 2026 indicate sustained governance stress; combined with an unfavourable economic backdrop (OECD slower growth projections) this raises the political stakes and incentives for confrontational measures.

Countervailing forces are significant. U.S. institutional complexity — federalism, multiple centers of authority, professional civil service, state election administration, independent courts (including an ideologically mixed ecosystem of state and some federal judges), a competitive media ecosystem, business and civil-society pushback — provides friction against rapid, large declines in EIU scores. The EIU scoring process is evidence- and indicator-driven and tends to incorporate multiple years of behavior; therefore isolated episodes of volatility or rhetoric do not automatically translate into large point decreases. The judiciary and state governments have in practice constrained executive overreach in several high-profile episodes since 2020, and similar dynamics could limit sustained institutional capture.

Weighing these factors, I assess the probability that the U.S. falls below 7.60 between 2025 and 2028 at **64%**. This reflects a view that erosion is more likely than not given current political trajectories (escalating executive assertiveness, high polarization, concentrated efforts to delegitimize opponents), but not near-certain because of institutional resilience, legal constraints, and political backlash risks that moderate and slow changes in the EIU's measured democracy score.

**Stage 2 — Market calibration (considering current market price Yes = 0.901):**

The market price (≈90% Yes) is substantially higher than my independent estimate (64%). Several plausible explanations for this gap:

- *Recency and narrative bias*: Traders may overweight high-salience events (the January 2025 policy shock, repeated inflammatory rhetoric) and conflate short-term volatility with durable institutional damage. The policy uncertainty spike provides vivid evidence that traders often use heuristics rather than the multi-indicator approach the EIU uses.

- *Risk aversion and tail-focus*: Many market participants focus on tail risk and regime-change scenarios and are willing to pay to hedge against catastrophic declines in democratic quality. That bidding pressure can push Yes prices above a fully rational aggregated mean probability.

- *Information asymmetry / event-driven bets*: Some traders may be acting on private or specialized information (e.g., expectations about specific executive orders, classified policy moves, or coordinated state-level actions) that the public news summary does not reflect. That can legitimately justify a higher market price, though it also increases variance.

- *Liquidity and momentum effects*: With >109k contracts traded, momentum and trend-following strategies may have amplified a directional price move once Yes began to dominate.

Why the market might be mispriced (overstating the chance): the EIU index is not a single high-frequency "sentiment" gauge; it aggregates multiple domains and often lags immediate political shocks. The market price seems to assume fast, substantive changes to legal and civic norms across multiple domains, whereas plausible paths often produce slower, incremental declines that may not sum to a >0.4–0.5 point fall before 2028. Additionally, the U.S. has many veto points and plural power centers — states, courts, private sector — that historically blunt abrupt democratic backsliding.

Why the market could be correctly high: if multiple risk vectors materialize together — sustained attack on election administration (including criminalization or mass decertification attempts), broad restrictions on press and protest, systemic non-compliance by courts or enforcement agencies, and state-level collusion to suppress opposition — then cumulative downshifts across several EIU subindices could plausibly breach 7.60. Market participants may be pricing in a non-linear cascade rather than a slow linear decline.

Bottom line: the market's ~90% yes reflects strong conviction and tail-focused risk pricing. My independent assessment (64%) places substantial probability on a drop below 7.60 but views the market as likely overstating near-term inevitability, albeit not impossibly so. Traders should consider whether they are pricing a realistic aggregation of indicators or overweighting singular high-salience events.
