Planner reasoning

This is a low-probability political arrest market; the key anchor is the current Polymarket price plus any concrete legal developments (DOJ investigations, grand juries, statute of limitations on Fauci's congressional testimony, Rand Paul referral). Base rate for arrests of former senior US officials absent an active indictment is very low. I'll pull the direct market price, cross-venue signals, and news on any DOJ/grand jury activity involving Fauci, plus the preemptive pardon issue.

# Current state Fauci has not been arrested, charged, or indicted as of the latest research (late Aug 2026). He faces a Senate contempt-of-Congress referral (Aug 2026) after invoking the Fifth Amendment 100+ times, active state-level AG investigative subpoenas (FL/WV/LA), and persistent perjury exposure tied to his Fifth Amendment testimony — but no arrest, grand jury indictment, or formal charge has occurred. The resolution mechanism requires an actual arrest/detention (not indictment, subpoena, contempt vote, or warrant issuance) by Dec 31, 2026. # Timeline of key events - 2025-01-19 (confirmed): Biden issues preemptive pardon covering Fauci's actions Jan 1, 2014–Jan 19, 2025 (Wikipedia; multiple outlets). - 2026-06 (confirmed): Fauci aide David Morens indicted for concealing federal records; arrested by armed agents (Science/AAAS). Fauci himself not charged. - 2026-06-23 (reported): Fauci subpoenaed after refusing to testify on COVID origins (Daily Mail). - 2026-07-13 (reported): Senator demands special counsel probe of Fauci over COVID-19 origins (NY Post). - 2026-07-29 to 2026-08-10 (confirmed): Florida AG Uthmeier subpoenas Fauci; teams with WV and LA AGs on "self-dealing" investigation; documents due Aug 31, 2026 (My Florida Legal, The Hill). - 2026-08-01 (confirmed): Fauci invokes Fifth Amendment 100+ times in Senate hearing (Fox News). - 2026-08-06 (confirmed): Senate Homeland Security Committee votes 8-7 to hold Fauci in contempt of Congress; Rand Paul says he'll ask DOJ to prosecute (multiple outlets). - 2026-08-06/07 (confirmed): DOJ says it "seriously reviews" referrals; no commitment made (Lawfare, AP-syndicated). - 2026-08-19/20 (confirmed): Fauci aide Morens pleads guilty to concealing COVID records (NPR); Fauci not charged. - 2026-08-23 (reported): Fauci launches legal defense fund amid ongoing investigations (KATU). # Event Will Anthony Fauci be arrested (physically taken into custody, booked, surrendered on warrant, or placed under house arrest/monitoring) before Jan 1, 2027? # Outcomes to forecast Yes / No # Kalshi market anchor No Kalshi-direct data returned (0 related markets found via kalshi_related search for "Fauci"/"arrested"/"indicted"). No Kalshi YES price available — must rely on Polymarket as cross-market anchor. # Sub-question answers 1. **Polymarket YES price/trend** — Current 10.75%; 7-day change -0.90%, 30-day change +4.80%; range 5.5%-23% over 90 days; volume $157,440 (polymarket_direct). 2. **Active federal/state investigation or indictment?** — No federal indictment or grand jury confirmed against Fauci himself. State-level: FL/WV/LA AGs issued subpoenas (self-dealing probe, docs due Aug 31, 2026); no state charges filed yet (claude_news, myfloridalegal.com). 3. **Does Biden pardon bar prosecution?** — Pardon covers federal conduct Jan 1, 2014–Jan 19, 2025, including Coronavirus Task Force work; does NOT cover post-pardon conduct (e.g., recent perjury in testimony) or state-level charges (claude_news, Wikipedia, CBS12). 4. **Rand Paul referral status** — Senate committee voted 8-7 (Aug 6, 2026) to hold Fauci in contempt; Paul hand-delivered resolution to AG/Pirro; DOJ has only said it "reviews" referrals, no charging decision or grand jury confirmed as of research date (Lawfare, The Hill). 5. **Base rate for arrest of former senior officials in ~14mo window** — code_execution model: 0.7%-4.1% via hazard-rate approach; pardon-adjusted low estimate ~0.28%; recommended central estimate ~1-3%. 6. **Calibration vs. other figures in same event** — No data retrieved (polymarket_related found 0 matches); comparison set unavailable. # Key facts (high-confidence, factual) 1. [Wikipedia] Biden pardoned Fauci preemptively for conduct 2014-01-01 to 2025-01-19. 2. [claude_news/AAAS] Aide David Morens indicted and later pled guilty (Aug 2026); arrested with armed tactical agents — shows DOJ aggressiveness toward associates, not Fauci directly. 3. [claude_news] Senate committee voted along party lines (8-7) to refer Fauci for contempt (Aug 6, 2026); no conviction, no criminal charge resulted. 4. [myfloridalegal.com/The Hill] FL, WV, LA AGs issued subpoenas to Fauci in COVID self-dealing probe; document deadline Aug 31, 2026. 5. [claude_news] Legal experts (Barbara McQuade) view prosecution as difficult given Fifth Amendment protections and pardon scope. # Cross-market signals - Kalshi related: none found. - Polymarket: 10.75% YES, slight downward 7-day drift but positive 30-day momentum (+4.8pp), suggesting recent news (contempt vote, subpoenas) modestly raised perceived risk. - Sportsbook implied: N/A. # Analyst opinions and speculation - Rep. Anna Paulina Luna urging governors/AGs (FL, TX, WV, AR) to pursue state cases; no confirmed Texas action (claude_news). - Florida AG Uthmeier suggested probe "could uncover grounds for criminal liability despite pardon" (Yahoo/AG office). - Commentators (Townhall) argue pardon effectively shields Fauci ("already cashed his get-out-of-jail-free card"). - DOJ described as facing "competing pressures" (WaPo) — no clear signal of imminent action. # Directional lean per outcome - **Yes**: Active contempt referral, multi-state AG subpoenas, perjury exposure outside pardon window, political pressure (Paul, Luna) — but none have yet produced an indictment or arrest; Fifth Amendment defense seen as strong. - **No**: Federal pardon covers most plausible conduct; no grand jury/indictment confirmed; legal experts skeptical of successful prosecution; Fauci's age/health; historical base rate for arrest of former senior officials is very low; only ~4 months remain in window after August 2026 news cutoff. # Gaps / unknowns - No Kalshi price data at all for calibration. - Outcome of Aug 31, 2026 state AG document deadline unknown. - Whether DOJ will convene grand jury on contempt referral unknown. - No comparison data for other "arrested before 2027" event entrants. - Unclear how much time remains between research cutoff (~Aug 2026) and Dec 31, 2026 resolution deadline (~4 months). # Calibration anchors - Polymarket YES: 10.75% (only external market price available; treat as rough anchor, likely elevated by recent news salience rather than fundamentals). - Base-rate/hazard model (code_execution): ~1-4%, central ~2%. - Historical precedent: no former senior US federal health official has been arrested in modern era for pandemic-response conduct; closest comparator (aide Morens) was arrested/indicted but pled guilty — Fauci himself remains uncharged.

1. Both forecasters anchor heavily on Polymarket (10.75%) and land at 5-7%, but neither seriously grapples with why the "hazard-rate base rate" (~1-4%, central ~2%) should be weighted more heavily than a thin, news-salience-driven prediction market with only $157k volume — they split the difference rather than justifying it. 2. Neither forecast explicitly addresses the resolution mechanism's inclusion of "surrender on warrant" — even a contempt-of-Congress criminal referral resulting in an actual DOJ charge could trigger a technical "arrest" via routine self-surrender, which is a a plausible low-probability pathway distinct from a dramatic FBI arrest; this pathway deserves more explicit modeling given the active 8-7 contempt vote and Rand Paul's DOJ referral. 3. Both cite "only ~4 months remain" but neither notes the Aug 31, 2026 AG document deadline is imminent relative to the forecast horizon — if that probe surfaces incriminating material, it could accelerate state-level charges before Dec 31, and neither forecaster scenario-tests this near-term catalyst. 3. Both forecasts converge suspiciously close (5% vs 7%) despite claiming independent reasoning, and neither explores the tail scenario where state AGs (unconstrained by the federal pardon) move faster than expected given Uthmeier's public claim that the probe "could uncover grounds for criminal liability despite pardon." 4. Neither forecaster discusses Fauci's age/health as a mitigating factor explicitly listed in the brief's "No" case, nor do they consider whether DOJ's demonstrated willingness to prosecute an aide (Morens) but not the principal actually signals a deliberate strategy to build a case against Fauci via cooperating witnesses — a scenario that could raise, not lower, medium-term arrest risk beyond the 4-month window (though outside this question's scope, it's underweighted as a signal of DOJ intent). 5. Both estimates (5%, 7%) sit above the model's own stated pardon-adjusted low estimate (~0.28%) and above the central hazard-rate estimate (~1-3%), essentially fully deferring to the Polymarket anchor without justifying why the market's illiquid, salience-driven price should dominate the more rigorous base-rate model.

5% (70% confidence)

Yes: 5% No: 95%

Fauci remains uncharged as of late Aug 2026, with only ~4 months left in the window; the federal pardon covers the 2014–Jan 2025 conduct that underpins most plausible charges, and the contempt referral has yielded only a non-committal DOJ 'reviews referrals' statement. Even the 'self-surrender on warrant' pathway requires a DOJ charging decision or state indictment that has not begun (no grand jury confirmed), and state AG probes are still at the document-production stage. The hazard-rate base rate (~1-3%) is more rigorous than a thin, salience-driven $157k Polymarket price at 10.75%, so I sit meaningfully below the market while preserving some weight for the genuine post-pardon perjury/state-charge tail and demonstrated DOJ aggressiveness (Morens). Final: ~5% Yes, consistent with both forecasters but grounded in the base rate rather than pure market deference.
