Based on: Ongoing Event
Kalshi prices the probability of the Republican candidate winning Iowa's 2026 Senate race at approximately 61%; Polymarket confirms a similar assessment. Incumbent Joni Ernst (Republican, senator since 2015) is running for her third term in Iowa. Iowa ranks among the most structurally Republican-leaning swing states of recent election cycles: Donald Trump carried Iowa by ~13 points in 2024. Even in a national Democratic Midterm wave scenario (Polymarket: 'Democratic Sweep' = 53%), Iowa remains extremely costly and logistically challenging terrain for Democrats. Crucially, Democrats can win the Senate majority without Iowa — by flipping Ohio (52% Democratic, Kalshi) and Texas (51% Democratic, Kalshi) — drawing resources away from Iowa. Ernst's moderate profile on farm subsidies and veterans' issues shields her from significant intra-state backlash.
Data basis for this prediction
- Kalshi: Republikanischer Kandidat gewinnt Iowa Senate 2026 = ~61 % (Stand 14.09.2026)
- Polymarket: Midterm Balance of Power – Democrats Sweep = 53 %; Senate = ~51 % D (Stand 14.09.2026)
- Iowa Präsidentschaftsergebnis 2024: Trump +13 % (Iowa Secretary of State, November 2024)
Verdict: Miss
Die Vorhersage ist klar gescheitert – aus zwei Gründen: (1) Joni Ernst trat nicht zur Wiederwahl an; sie kündigte an, 2026 nicht mehr zu kandidieren (Quelle: Fox News). (2) Der republikanische Kandidat – Repräsentantin Ashley Hinson – verlor das Rennen gegen den Demokraten Josh Turek (50,5 % vs. 46,4 %). Turek gewann damit den Sitz für die Demokraten und beendete über ein Jahrzehnt republikanische Kontrolle beider Iowa-Senatsmandate. NBC News und NPR bestätigten den Sieg Tureks am Wahlabend (3. November 2026). Die Grundannahme der Vorhersage – dass Ernst antritt und als Amtsinhaberin einen Amtsbonus genießt – war schlicht falsch.

Democrats won both chambers historically at the November 3, 2026 midterms (Senate 54:44, House 258 seats — largest majority since 1993). Trump's disapproval rating stands at 62% (FiveThirtyEight, Nov 2026). Based on documented behavioral pattern: after the 2020 presidential election, Trump posted voter fraud claims within 48 hours; after the 2022 midterms, challenges followed within a week. Metaculus community places >70% probability on public contesting after major GOP losses. A public statement via Truth Social, press release, or confirmed media interview by November 15, 2026 counts as verification (Reuters or AP).

Ukrainian, US, and Russian negotiators convene November 10–11 in Abu Dhabi. Russia conducted large-scale long-range strikes on Ukrainian energy infrastructure and logistics hubs on November 3–4; Ukraine responded with drone strikes on the Ryazan refinery. Positions on territory and security guarantees remain far apart. No Polymarket or Kalshi market covers this specific event; historical base rate for failure of comparable trilateral talks: >80%.

Spain holds a general election on 29 November 2026. Polymarket prices Feijóo as next PM at 85%, Kalshi at 82% — both serve as anchors. A separate Polymarket market gives PP+Vox a 92% probability of a joint majority (>176/350 seats). Current polls (Sondaxe) show PP at 29.2% narrowly ahead of PSOE (26.9%); Vox is tracking slightly higher. Feijóo failed to form a government in 2023, but market odds reflect the lesson learned: PP+Vox is now seen as stable enough. No deviation from market anchor warranted.
