Planner reasoning

This is a long-shot political novelty market resolving only if an executive action or enacted law directs Trump's likeness be added to Mt. Rushmore before Jan 21, 2029. A bill (e.g., Rep. Anna Paulina Luna's) has been introduced but enactment is extremely unlikely; the key questions are legislative status, any executive action signals, and feasibility objections from the NPS/engineers. The Kalshi price is the primary anchor, cross-checked against Polymarket and related markets.

# Current state No executive action or bill has been enacted directing Trump's likeness be carved into Mt. Rushmore. Rep. Anna Paulina Luna's bill (introduced Jan 2025) remains stalled in committee as of July 2026; NPS maintains Rushmore is a "completed work" with no room, and engineers/geologists say a fifth face is not physically feasible. Kalshi prices this at 12% YES. # Timeline of key events - 2025-01-28: Rep. Anna Paulina Luna (R-FL) introduces bill directing Trump's carving into Mt. Rushmore (confirmed, luna.house.gov). - 2026 (date unspecified, pre-April): Interior Secretary Doug Burgum states there is "certainly" room for Trump's face (confirmed statement, but contradicts NPS official position) (NBC News/CNN). - 2026-04-01: Viral hoax claims sculptors are actively carving Trump's face — confirmed to be an April Fools' fabrication by Daily Mail (Snopes/Yahoo). - 2026-06: Trump posts AI-generated image of himself on Rushmore to Truth Social; no textual policy statement attached (confirmed post, LegalClarity). - 2026-07-03/05: Trump visits Mount Rushmore for America's 250th anniversary celebration; does not explicitly call for his own addition in public remarks; CNN reports Luna's bill "stalled" and her office declined comment on renewed push (confirmed, CNN/WaPo). - 2026-07 to 08: Multiple opinion pieces ("Perish the thought") published opposing the idea — reflects continued media/political debate, not policy movement (reported, Duluth News Tribune, Citizens' Voice). # Event Will an executive action or enacted law direct Trump's likeness be sculpted into Mt. Rushmore before Jan 21, 2029 (KXMTRUSHMORE-29)? # Outcomes to forecast - Yes - No # Kalshi market anchor Current YES price: **12%**. 7-day change +1pt, 30-day change +1pt. Price range over 60 days: 6%-17%. Average daily volume ~201 contracts — modest but active. Trend is slightly upward but rangebound near the low teens. # Sub-question answers 1. **Luna's bill status** — Introduced Jan 28, 2025; remains stalled in committee as of July 2026, with no floor votes or advancement reported (CNN). 2. **Executive/White House signals** — No formal EO or memorandum issued. Interior Sec. Burgum voiced informal support ("certainly have room"), but this contradicts NPS's official stance; White House called Trump "a great addition" per WaPo headline but no directive issued (CNN, NBC, WaPo). 3. **NPS/engineering feasibility** — NPS calls Rushmore a "completed work of art" with "no viable locations left." Geologists/engineers (e.g., Paul Nelson, former monitoring engineer) and original sculptor Borglum's own 1936 writings state the rock structurally cannot support a fifth head (NBC, CNN, LegalClarity). 4. **Base rate / legislative calendar** — No congressional bills tool found any matching legislation beyond Luna's (0 results in congress_bills search, suggesting stalled/inactive status). Symbolic long-shot bills of this type historically almost never become law absent leadership backing; no signal of GOP leadership prioritization. 5. **Cross-market prices** — Polymarket has zero matching markets (no cross-check available). Kalshi is the sole quantified signal at 12%. 6. **Recent momentum (last 90 days)** — Trump's July 2026 Rushmore visit generated speculation but no explicit personal call for his own carving; AI-image posting is symbolic/social media activity, not policy action. Legal experts flag NEPA/NHPA review and potential tribal/environmental lawsuits as additional barriers even if political will existed (Northeastern, Snopes). # Key facts (high-confidence, factual) 1. [CNN] Luna's bill introduced Jan 2025, stalled in committee as of July 2026. 2. [NBC/CNN] NPS official position: Rushmore is "completed," no room for additional carving. 3. [NBC/CNN] Engineering/geological experts, including original sculptor Borglum (1936), say a fifth face is not feasible given rock composition. 4. [LegalClarity] Even with legislative and executive support, NEPA/NHPA reviews and potential tribal/environmental litigation would be required. 5. [Kalshi] YES price 12%, up modestly over 30 days, range 6-17% over past 60 days. # Cross-market signals - Kalshi related: "Trump bring back manufacturing" (14.2%) and other Trump-term markets show similarly low probabilities for ambitious/symbolic Trump-era outcomes — consistent base rate pattern. - Polymarket: No matching markets found — no cross-market confirmation available. - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - Legal scholar Jeremy Paul (Northeastern) — congressional approval would likely be required plus expects litigation from tribal nations/environmental groups even if political will existed. - Media commentary (Duluth News Tribune, Citizens' Voice, mid-2026) — largely skeptical/opposed op-eds, reflecting no momentum toward actual policy action. - WaPo framing: "White House says Trump would make great addition" — rhetorical support only, not policy commitment. # Directional lean per outcome - **Yes**: Some political tailwinds (Trump's visible interest via AI-image posts, Burgum's supportive comments, Luna's bill exists, ~2.3 years remain until close) — but no structural progress on any front. - **No**: NPS institutional resistance, geological/engineering infeasibility per independent experts, stalled legislation with no floor movement, added legal/regulatory hurdles (NEPA/NHPA, tribal claims), lack of Polymarket interest suggesting low broader speculative appetite. Weight of evidence strongly favors No. # Gaps / unknowns - No visibility into whether Luna's bill could be revived with leadership support before 2029. - Unclear whether Trump might attempt a symbolic/non-binding EO that could arguably satisfy resolution criteria without going through Congress. - No Polymarket data for cross-market triangulation. - No polling/base-rate data specifically on how often symbolic monument bills historically pass. # Calibration anchors - Kalshi current YES price: 12% (primary anchor). - Related Kalshi Trump-term ambitious/symbolic outcome markets trade in similar low-teens range (e.g., manufacturing share 14.2%), suggesting market consistently discounts high-profile Trump symbolic goals. - Historical precedent: No prior president has been added to Rushmore since original 1941 completion despite decades of similar proposals (e.g., for Reagan, others) — none advanced past discussion stage.

1. **Resolution-criteria mismatch**: The event resolves on "executive action or enacted law direct[ing]" the carving — not on actual completion or feasibility. Both forecasters spend most of their rationale on geological infeasibility (Borglum's 1936 writings, NPS "completed work") and legal hurdles (NEPA/NHPA, tribal litigation), which are largely irrelevant to whether Trump signs a symbolic/unenforceable EO — a much lower bar he has cleared for other legacy-branding actions (e.g., renaming initiatives). This "cheap symbolic EO" pathway is flagged as the "main residual risk" by Forecast 1 but not quantified separately, and the brief's own gap note — "Unclear whether Trump might attempt a symbolic/non-binding EO that could arguably satisfy resolution criteria" — is underweighted by both. 2. **Anchoring with minimal independent adjustment**: Both forecasts land within 2 points of the 12% Kalshi price (10% and 12%), essentially replicating the market rather than stress-testing it. Given the brief notes only ~201 average daily contracts and a wide 6–17% 60-day range, this is a thin, potentially noisy market — neither forecaster discusses whether the anchor itself deserves a wider confidence interval or whether their point estimate should differ meaningfully from it. 3. **2026 midterms not modeled**: Luna's bill's fate depends on committee/leadership prioritization, yet neither forecast discusses how the 2026 midterm elections (occurring within the forecast window) could flip House control or leadership priorities, either killing the bill entirely or (less likely) reviving it with a friendlier committee chair. This is a concrete, dated catalyst that should shift probability mass over time, not just a static "18+ months stalled" observation. 4. **Time-varying probability not addressed**: With ~2.3 years of runway remaining and Trump's demonstrated pattern of escalating symbolic gestures (AI image, Rushmore visit, Burgum's comments) as his term progresses, there's a plausible late-term "legacy push" scenario (e.g., final-year executive actions before leaving office) that neither forecast explicitly weighs — both treat the probability as roughly static rather than considering whether risk is front- or back-loaded within the window. 5. **Overconfidence convergence without divergent reasoning**: Confidence levels (0.62 and 0.74) are reported without underlying uncertainty ranges, and both forecasters reach nearly identical point estimates through similar reasoning chains — this convergence could reflect correlated blind spots (e.g., both dismissing the EO-only pathway similarly) rather than independent confirmation of the 12% anchor. 6. **No engagement with historical base rate on symbolic monument bills**: The brief flags "No polling/base-rate data specifically on how often symbolic monument bills historically pass" as a gap, yet neither forecaster attempts a reference-class estimate (e.g., rate at which single-sponsor symbolic bills without leadership backing become law) to sanity-check the 10-12% figure against a broader prior.

11% (68% confidence)

Yes: 11% No: 89%

Both forecasts converge near the 12% Kalshi anchor, and the red-team critique correctly notes that resolution likely hinges on a cheap symbolic executive order rather than actual carving feasibility — meaning the geological/NPS objections are less decisive than the rationales suggest. However, that EO-optionality is plausibly what the market's 12% already prices: Trump has passed multiple high-salience trigger points (250th anniversary Rushmore visit, AI-image post) without issuing any directive, which is mild evidence against the legacy-push scenario materializing. Luna's bill remains stalled with zero leadership backing, and the reference class of single-sponsor symbolic monument bills becoming law is near zero. I land at 11% YES — essentially the market anchor with a slight shade down for repeated non-action at natural catalysts, while keeping meaningful probability for a late-term symbolic EO over the remaining ~2.3 years.
