Sub-questions (Fermi decomposition)

Planner reasoning

This is a Polymarket question about whether Trump and Putin will fail to meet in person before Dec 31, 2026. The key drivers are the state of US-Russia diplomacy/Ukraine peace negotiations, any announced summit plans (e.g., Budapest, which was called off in Oct 2025), and the base rate of leader summits materializing. Market price on Polymarket is the primary anchor, supplemented by news search and cross-venue triangulation.

# Current state No second Trump-Putin in-person meeting has occurred since the August 15, 2025 Alaska summit; a follow-up Budapest summit was agreed then cancelled in October 2025. As of the latest reporting (July 2026), diplomacy continues via envoys (Witkoff/Kushner) and a Trump-Putin phone call, but no in-person leaders' meeting is scheduled. A possible G20 Miami encounter (Dec 14-15, 2026) is floated but Trump himself doubts Putin will attend. # Timeline of key events - 2025-08-15: Trump-Putin summit at Joint Base Elmendorf-Richardson, Anchorage, Alaska — confirmed (Wikipedia, CNBC). Ended without ceasefire deal. - 2025-10-16: Trump and Putin agree by phone to a second summit in Budapest, Hungary — confirmed (Tribune India). - 2025-10-31: Budapest summit cancelled after Russia's Foreign Ministry reiterated hardline territorial demands; Trump says he personally called it off — confirmed (Moscow Times/FT, CBS News). - 2025-11-25: Trump signals he'll meet Putin (and Zelensky) only in "final stages" of a peace deal — reported (Axios). - 2026-01-23/late Jan: Witkoff/Kushner hold marathon overnight talks with Putin in Moscow; Kremlin insists territorial issue must be resolved first — confirmed (Euronews, ABC News). - 2026-04-24: White House to invite Putin to G20 Miami summit (Dec 14-15, 2026 at Trump National Doral); Trump doubts he'll accept — reported (Moscow Times). - 2026-05 (week after Trump-Xi summit): Putin invited to China; Putin-Xi meeting occurs, overshadowing US-Russia leader diplomacy — reported (The Diplomat). - 2026-07-03: "Spirit of Anchorage" declared dead by both Trump and Putin amid Ukrainian fuel-crisis strikes and Putin's rejection of Zelensky peace proposal — reported (Meduza). - 2026-07-05: ~90-minute Trump-Putin phone call; Putin reiterates open invitation to Moscow; no in-person meeting set; Zelensky's call for one-on-one meeting refused by Putin — confirmed (Moscow Times, Al Jazeera). - 2026-07-23/24: Rubio-Lavrov meeting dampens peace hopes; Trump-Zelensky meeting planned in Washington — reported (JPost, Arab News). - 2026-08-14/15: One-year retrospectives on Alaska summit note "goodwill is gone," no second meeting held — reported (National Post, RTE). # Event Will Trump and Putin NOT meet (in person) between market creation and Dec 31, 2026? # Outcomes to forecast - Yes (no meeting occurs by Dec 31, 2026) - No (a qualifying meeting occurs) # Kalshi market anchor No direct Kalshi price was returned for this specific ticker in the research. Closest Kalshi proxy: "Where will Trump and Putin next meet? — Hungary" priced at 7% (down 7pts in 7 days, 30d flat), suggesting low confidence in any near-term specific-venue meeting. Polymarket (same event, cross-platform) currently prices "No meeting" (Yes on this question) at 63.5%, down from a 76.5% high, -3% (7d) and -6.5% (30d), on $86K volume — trending toward more likely a meeting occurs than earlier in the period, but still favoring "No meeting." # Sub-question answers 1. **Polymarket price/trend** — 63.5% currently (Yes = no meeting), down 6.5pts over 30 days and 3pts over 7 days; range 47-76.5% over 81 days, indicating volatility tied to news cycles (Polymarket direct). 2. **Scheduled/floated summit** — No confirmed date/venue currently scheduled. Budapest was agreed then cancelled (Oct 2025). G20 Miami (Dec 14-15, 2026) is a floated venue where Putin is invited, but Trump doubts attendance (Moscow Times, Apr 2026); Kalshi's Hungary-specific contract sits at just 7%. 3. **Peace plan/Witkoff-Dmitriev status** — Talks ongoing but unresolved; Jan 2026 Witkoff/Kushner-Putin Moscow talks "frank, constructive" but no deal; Kremlin insists territorial issues must be resolved first (Euronews, ABC News). No agreement yet that would necessitate a summit; July 2026 "Spirit of Anchorage" declared dead (Meduza). 4. **Prior cancelled summits** — Yes: Budapest summit (agreed Oct 16, 2025) cancelled Oct 31, 2025 after Russia's Foreign Ministry repeated maximalist demands (territory cession, troop reduction, no-NATO pledge); Trump says he called it off (CBS, Moscow Times/FT). 5. **Multilateral 2026 events** — G20 Miami, Dec 14-15, 2026 (US-hosted, Doral resort) is the key candidate where both could be present; Putin invited but attendance uncertain. Putin-Xi meeting in China (May 2026) did not include Trump. No other multilateral overlap explicitly identified in research. 6. **Other market signals** — Kalshi "Hungary" location contract at 7% (falling); no Kalshi Ukraine-ceasefire market found beyond a Ukraine election contract at 2% (down sharply). No relevant Polymarket-related matches found via keyword scan (0 markets), suggesting this may be a fairly isolated/niche contract. # Key facts (high-confidence, factual) 1. [Wikipedia] Only Trump-Putin meeting since 2019 occurred Aug 15, 2025, Anchorage, Alaska; ended without agreement. 2. [Moscow Times/CBS] Budapest summit agreed Oct 16, 2025, cancelled Oct 31, 2025 by Trump due to Russian hardline demands. 3. [Euronews/ABC] Jan 2026 Witkoff/Kushner-Putin Moscow talks produced no deal; territorial issue unresolved. 4. [Moscow Times] G20 Miami (Dec 14-15, 2026) invitation to Putin issued; Trump doubts acceptance. 5. [Al Jazeera/Moscow Times] July 5, 2026 Trump-Putin phone call — no in-person meeting scheduled; Putin refused Zelensky's one-on-one meeting request. 6. [Meduza] By July 2026, both sides acknowledge post-Alaska diplomatic momentum has collapsed. # Cross-market signals - Kalshi related: "Hungary" specific-venue contract at 7%, falling; no direct Kalshi price captured for this Yes/No ticker. - Polymarket: 63.5% Yes ("no meeting"), trending down (toward more meeting-likely) over 7d/30d but still net favoring no meeting. - Sportsbook implied: none found. # Analyst opinions and speculation - Rubio (per Newsweek): any future summit requires "real chance to get something positive," implying no meeting absent probable deal progress. - Trump has suggested he'd only meet Putin (possibly with Zelensky) in "final stages" of a deal (Axios), implying meeting is conditional on unresolved territorial disputes being settled first. - Analysts note G20 Miami as most plausible 2026 encounter, but Trump's own stated doubt undercuts this. # Directional lean per outcome - **Yes (no meeting)**: Supported by repeated stalling (Budapest cancellation), unresolved territorial impasse, envoy-only diplomacy through mid-2026, Trump's stated conditions, and Kalshi's low (7%) Hungary-specific pricing. Polymarket at 63.5% still favors this outcome. - **No (meeting occurs)**: Supported by open Moscow invitation to Trump, floated G20 Miami in December 2026, historical precedent of quick pivots (Budapest was arranged in one phone call), and Polymarket's declining trend (down from 76.5% high) suggesting increasing meeting probability as year progresses. # Gaps / unknowns - No direct Kalshi YES price for this exact ticker was retrieved — reliance on Polymarket and a related Kalshi venue-specific contract as proxies. - Uncertain whether G20 Miami (Dec 14-15, 2026) falls within window and whether Putin will actually attend given ICC warrant and Trump's own doubts. - No clarity on whether a Ukraine peace deal will be reached before Dec 31, 2026, which is the main plausible catalyst for a summit. # Calibration anchors - Polymarket current price: 63.5% Yes (no meeting), high 76.5%, low 47% over 81 days. - Kalshi related Hungary-venue contract: 7% (proxy, not this ticker). - Precedent: a summit was arranged and cancelled within two weeks in Oct 2025, showing volatility/fast reversals are plausible before year-end.

1. Both forecasters anchor almost entirely on Polymarket's 63.5% "no meeting" price without addressing the key caveat in the brief that Polymarket volume is only $86K and "no relevant Polymarket-related matches found via keyword scan," meaning the cross-platform proxy itself may be thin/unreliable — neither discusses this liquidity/confidence caveat before leaning above it. 2. Neither forecast explicitly reconciles the discrepancy between the Kalshi Hungary-venue proxy (7%, implying ~93% chance the *next* meeting is NOT in Hungary) and their own "No" (meeting occurs) probabilities of 28-34%; since G20 Miami is the only other plausible venue and Trump himself doubts Putin's attendance there, the arithmetic implies "meeting occurs anywhere" should probably be pushed lower than both forecasts allow, unless they think a Moscow visit by Trump is a live alternative — this isn't addressed. 3. Both treat the Budapest "arranged-then-cancelled in two weeks" precedent as symmetric evidence for quick reversals, but arguably it's stronger evidence for the "Yes" (no meeting) case, since it demonstrates that even when a summit is scheduled, it doesn't survive Russian hardline demands — this asymmetry is underweighted in both calibration toward "No." 4. Neither forecast seriously engages with the ICC arrest warrant issue for Putin, which is a major logistical/legal constraint on any US-hosted meeting (G20 Miami) and could suppress the "No" probability further than either forecaster's number suggests; this is flagged only briefly in "Gaps/unknowns" but not integrated into either rationale. 5. Both forecasts landed close together (0.72 vs 0.66) despite one explicitly citing "post-July collapse in momentum" (Forecast 1) as justification for being further above the anchor — but neither considers the possibility of a rapid diplomatic breakthrough triggered by battlefield developments or a Ukraine ceasefire before December, which historically (per the brief's own Budapest example) can materialize within weeks and thus deserves fatter tail-risk treatment on the "No" side than a static ~30% allows. 6. Neither forecaster addresses whether an accidental/incidental encounter (e.g., both attending G20 without a bilateral) would count as "meeting" under the question's resolution criteria, which could materially shift probabilities if the definition is ambiguous — this ambiguity in the outcome specification is not flagged by either.

73% (60% confidence)

Yes: 73% No: 27%

As of the latest reporting (mid-August 2026), no second Trump-Putin meeting has occurred, none is scheduled, and both sides have declared the post-Alaska 'Spirit of Anchorage' dead, leaving roughly 4.5 months for a summit that Trump has conditioned on being in the 'final stages' of a peace deal that remains far off (Kremlin territorial preconditions unresolved). The only plausible venue, G20 Miami (Dec 14-15), carries Trump's own stated doubt about Putin's attendance plus ICC-warrant and logistical friction, and the Kalshi Hungary-venue proxy at 7% and falling corroborates weak near-term summit expectations. The Budapest episode cuts more toward 'no meeting' than both forecasters allowed: even a scheduled summit collapsed within two weeks under Russian maximalism. I therefore sit modestly above the thin ($86K volume) Polymarket anchor of 63.5%, at ~73%, while preserving a non-trivial 27% for the genuine possibility of a rapid, phone-call-driven pivot or a ceasefire breakthrough — and for ambiguity over whether an incidental G20 encounter would resolve as a meeting.
