final rationale
Mean of 2 draws (0.67, 0.65). (0) Nothing is resolved yet. The election is November 3, 2026, and AP, Fox and NBC have made no call. Alaska's ranked-choice tabulation is scheduled for about November 18, with certification targeted for November 25. That falls far inside the July 31, 2027 backstop, so 'Other' is negligible. (a) About three weeks remain to Election Day. Early voting starts October 19, and resolution could take until late November. (b) If today's polling holds, Peltola wins the final ranked-choice round by roughly 1–3 points. The evidence: RCP average +1.2, DDHQ average +2.5, InsiderAdvantage 50–48 (Oct 11), ASR 51–49, AARP 53–47, NYT/Siena +7. Sabato has moved the race to Lean D, DDHQ gave her just over 60% (Sep 25), and the national environment is about D+8. (c) NO scenario: Alaska's R+13 lean reasserts itself. The Trump rally (Oct 13) and Vance visit drive turnout among older Republicans, the conduct and slur stories erode her support, and polls overstate Democrats as they did in 2024, when Peltola cleared 50% in the primary yet lost the final round by about 2 points. (d) YES scenario: her 49.5% primary share carries into a high-turnout November. As the only Democrat she faces a split Republican field, outraises Sullivan heavily, and the blue national environment lets her win the final round by 2–6 points. The Polymarket anchor is 72.5%, and the Sullivan contract at 28.5% is consistent with it. Models (DDHQ about 60%) and Cook's Toss-up rating sit below the market, and Alaska has a record of polling misses against Democrats, so I shade modestly down to 0.67.

Planner reasoning
This is a Polymarket election question, so polymarket_direct is the price anchor and resolution_source covers the AP/Fox/NBC call. Kalshi and other Polymarket markets on the Alaska Senate race give an independent crowd and cross-market prices to compare against. The Wikipedia race page supplies the candidate field and polling, and Alaska's ranked-choice system matters for how the race resolves.

Research loops, bottom lines
- current state: Peltola has a modest, consistent polling lead (about 1–3 points in the averages, with a few R-leaning polls showing Sullivan ahead) and a favorable shift in ratings, but the race is within the margin of error. Alaska's Republican lean and the Trump/Vance campaigning keep the outcome uncertain. Ranked-choice counting may also delay the AP/Fox/NBC calls, though certification is well before the July 2027 deadline.
- base rate: The outside view is a near coin-flip with a modest Peltola lean. Raters and models (Sabato Lean D, DDHQ about 60%+, Cook Toss-up) and polling averages of about +1 to +2.5 Peltola sit against a strongly Republican base rate (Alaska R+12 to 13 in 2024, no Democratic Senate win since 2008). Peltola's strong primary, the D+8 national environment and her personal-conduct allegations are the key swing factors. Polls in Alaska have a history of error, and resolution may be slow if the race is close.
- yes case: The strongest YES case is a consistent final-round polling lead of about 2 to 6 points from mixed sponsors, a near-50% primary in higher turnout, a favorable ballot structure and money advantage, and Sabato, DDHQ (about 60%+) and Cook (Toss-up, "well-positioned") all treating her as the slight favorite. The YES path is that the primary result carries into November, unlike 2024, with Peltola winning the final ranked-choice round by a few points.
- no case: The strongest NO case rests on Alaska's R+13 baseline, a Peltola lead of only about 1-3 points in most polls, the Trump/Vance push, older-voter turnout, and unresolved conduct allegations; Cook still says Toss-up. Deadline arithmetic gives NO no help: certification is targeted for Nov 25, well before Jul 31, 2027, so a delayed call does not produce "Other" unless there is an extraordinary dispute.

- [2026-10-11] A new InsiderAdvantage poll of likely voters (±2.83) has Peltola 50%, Sullivan 48% after ranked-choice reallocation. https://politicalwire.com/2026/10/11/peltola-leads-sullivan-in-alaska-senate-race-2/ (search snippet only; page could not be fetched)

- [2026-10-07] Alaska Survey Research (Oct 1-3) shows Peltola ahead by 2 points after ranked-choice tallying, down from 3.8 points about four weeks earlier. Its owner, Ivan Moore, has publicly said Sullivan "needs to be voted OUT", and the poll's margin of error is 3%. Moore says the race is "polarized and locked in place" and comes down to turnout. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-10-07] Two other late-September polls cited by the NYT tracker show Sullivan ahead 47-46. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-10-06] Sabato's Crystal Ball moved the race to Leans Democratic from Toss-up. It is the first Democratic-favorable Crystal Ball Alaska Senate rating in 18 years.

- [2026-10-01] The NYT/Siena poll (Sept 22–Oct 1, 504 LV, ±5.1) has Peltola 50%, Sullivan 43%. Quantus (Sept 28–30) has Sullivan 46.1%, Peltola 45.5%. Trafalgar (R, Sept 22–24) and co/efficient (R, Sept 14–17) had Sullivan narrowly ahead. https://political.org/2026-senate-elections/ and https://www.realclearpolling.com/polls/senate/general/2026/alaska/peltola-vs-sullivan
- [2026-10-03] The RealClearPolling average (polls through Oct 3) is Peltola 48.5%, Sullivan 47.3%. https://www.realclearpolling.com/polls/senate/general/2026/alaska/peltola-vs-sullivan
- [2026-10-05] VP Vance rallied for Sullivan in Fairbanks. Inside Elections moved the race to Toss-up on Oct 1. https://political.org/2026-senate-elections/
- [2026-09-23] The NYT reported, citing former aides, that Peltola had angry outbursts at staff. Sabato judged the story may not have "legs". https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-08-18] In the top-four primary, Peltola got 49.5% and Sullivan 41.4%. Two other candidates are also on the general-election ballot: Dan J. Sullivan Jr. (no party affiliation) and Gerald Heikes (R). The general election uses ranked-choice voting. https://en.wikipedia.org/wiki/2026_United_States_Senate_election_in_Alaska
- [2026-09-11] The AARP poll (Fabrizio Ward/Impact, 800 LV) had Peltola 46%, Sullivan 41%, Sullivan Jr. 4%, Heikes 3%, and 53-47 after ranked-choice. https://thehill.com/homenews/campaign/6095497-peltola-leads-sullivan-alaska-senate-race-poll/
- [2026-07-29] Peltola had raised $18.55M against Sullivan's $9.14M. Sullivan had more cash on hand, $7.30M against $4.64M. I found no Q3 data. https://www.yahoo.com/news/politics/articles/peltola-leads-alaska-senate-race-202450471.html
- [Scheduled] Early voting begins Oct. 19 and Election Day is Nov. 3. Trump's rally is Oct. 13. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
BOTTOM LINE: Peltola has a modest, consistent polling lead (about 1–3 points in the averages, with a few R-leaning polls showing Sullivan ahead) and a favorable shift in ratings, but the race is within the margin of error. Alaska's Republican lean and the Trump/Vance campaigning keep the outcome uncertain. Ranked-choice counting may also delay the AP/Fox/NBC calls, though certification is well before the July 2027 deadline.
NOT FOUND: Any AP, Fox or NBC race call, which would not exist yet. Q3 FEC fundraising figures (the Oct 15 filing is not yet out). A fetched copy of the Cook Political Report ratings page. Official Alaska Division of Elections certification dates.
report: base rate
- [2026-10-07] Sabato's Crystal Ball moved Alaska Senate from Toss-up to Leans Democratic. It was the first Democratic-favorable Crystal Ball rating for an Alaska Senate race in 18 years. Cook Political Report still rated it a Toss-up as of Oct 7. The Crystal Ball began the cycle at Safe Republican. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-09-25] Decision Desk HQ's model gives Peltola "just over a 3 in 5" chance. It is the Democrats' second-most-likely flip. DDHQ's polling average was about Peltola 50, Sullivan 48. The generic ballot was D+8 and Trump's approval about 38%. https://decisiondeskhq.substack.com/p/alaska-senate-polls-peltola-favorite-sullivan-2026-midterms-forecast-update-approval-generic-ballot
- [2026-10-03] The RCP average (Sep 14 to Oct 3) was Peltola +1.2 (48.5 to 47.3). The polls in it: Alaska Survey Research +2 Peltola; Quantus +1 Sullivan; NYT/Siena +7 Peltola (50-43, Sep 22 to Oct 1); co/efficient +3 Sullivan. https://www.realclearpolling.com/polls/senate/general/2026/alaska/peltola-vs-sullivan
- [2026-09-24] Trafalgar (R) had Sullivan 46.8, Peltola 45.5. It was fielded Sep 22-24, around the NYT story on Peltola's conduct toward staff. AARP (Fabrizio Ward/Impact) had Peltola 46-41 on first choice and 53-47 after ranked-choice rounds. https://thealaskastory.com/new-alaska-senate-poll-puts-sullivan-narrowly-ahead-but-cannot-measure-full-impact-of-peltola-revelations/ ; https://thehill.com/homenews/campaign/6095497-peltola-leads-sullivan-alaska-senate-race-poll/
- [2026-08-18] In the top-four primary, Peltola got 49.5%, Sullivan 41.4%, and "Dan Sullivan" (a second, nonpartisan-listed candidate) 2.5%. Alaska is the same RCV system as 2022. https://news.ballotpedia.org/2026/09/14/alaska-voters-to-decide-on-the-second-u-s-senate-general-election-using-ranked-choice-voting/
- [2026-10-07] The ASR pollster says the Oct 1-3 poll had Peltola +2 after RCV, down from +3.8 four weeks earlier. The ASR owner has publicly said Sullivan should be voted out, so it is a partisan-leaning pollster. The owner says second-choice votes for the two minor Republicans split about evenly between the main candidates. Early voting begins Oct 19. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-10-10] Ongoing risk: after the Sept 23 NYT report, Alaska Landmine alleged Peltola used a racial slur in 2024. This is an unverified report, relayed by a partisan outlet. Sabato noted NYT polling suggested the first story lacked "legs." https://townhall.com/news/mattvespa/2026/10/10/latest-alaska-dem-mary-peltola-story-involves-her-allegedly-dropping-racial-slurs-n2684462
- [2026-10-12] Trump is scheduled to rally for Sullivan in Wasilla on Oct 13 and Vance has already campaigned in Fairbanks. Peltola raised $18.55M against Sullivan's $9.14M through Jul 29, but Sullivan had more cash on hand ($7.30M vs $4.64M). https://www.yahoo.com/news/politics/articles/peltola-leads-alaska-senate-race-202450471.html
- [2026-09-25] Historical reference class: Trump carried Alaska by 13.1 points in 2024. Democrats last won an Alaska Senate race in 2008 (Begich, against the scandal-tainted Ted Stevens). Sullivan won in 2020 by 12.7 points. Peltola is the only Democrat to win statewide since 2010. Her 2024 House loss to Begich was far closer than Harris's result in the state. https://decisiondeskhq.substack.com/p/alaska-senate-polls-peltola-favorite-sullivan-2026-midterms-forecast-update-approval-generic-ballot ; https://en.wikipedia.org/wiki/2026_United_States_Senate_election_in_Alaska
- [2026-10] Poliwave model (stale, through Sep 17 polls): Lean D, Peltola +2.7 forecast. A prediction-aggregator page (predictionedge.com, 2026-10-08) showed live odds of about 76% Peltola; this is a third-party aggregator and I could not confirm the source venue. https://www.poliwave.com/us/ak/sen-fed ; https://www.predictionedge.com/elections/us-senate/alaska-race/
- [2026-09-14] Resolution timing: Alaska RCV counts take about 2 weeks after Election Day because absentee ballots are counted through the cure/receipt period. AP, Fox and NBC may not call a close race on Nov 3-4, so the market could fall back to certification. That would still land well before the Jul 31, 2027 backstop. I could not confirm the 2026 certification calendar on a fetched page. https://news.ballotpedia.org/2026/09/14/alaska-voters-to-decide-on-the-second-u-s-senate-general-election-using-ranked-choice-voting/
- [2026-09-26] Baseline track record: in 2024, Alaska polls and the national environment overstated Democrats' strength in Alaska. Peltola lost the House race to Begich in 2024 even though she was favored in some polls. This is background from memory and I did not verify it. Treat it as weak evidence. https://thehill.com/homenews/campaign/6131462-sabatos-crystal-ball-shifts-alaska/
BOTTOM LINE: The outside view is a near coin-flip with a modest Peltola lean. Raters and models (Sabato Lean D, DDHQ about 60%+, Cook Toss-up) and polling averages of about +1 to +2.5 Peltola sit against a strongly Republican base rate (Alaska R+12 to 13 in 2024, no Democratic Senate win since 2008). Peltola's strong primary, the D+8 national environment and her personal-conduct allegations are the key swing factors. Polls in Alaska have a history of error, and resolution may be slow if the race is close.
NOT FOUND: Cook's current numeric odds, Silver Bulletin/538-style model odds, and a verified 2026 certification date. The Sabato page itself could not be fetched, so its claims are confirmed only through the Juneau Independent. The live Polymarket price was deliberately not sought.
report: yes case
YES means: Mary Peltola is the winner of the 2026 Alaska U.S. Senate election, as called by AP, Fox and NBC, or by official certification if they don't agree. Certification comes after ranked-choice tabulation.
- [2026-08-29] Primary turnout far exceeded 2024's. The ADN reported 166,853 ballots counted against 108,906 in the 2024 primary. Peltola had 82,165 votes (49.5%) to Sullivan's 41.4%. A larger electorate with Peltola near 50% is the base of the YES case. The fourth-place finisher, Democrat David Leslie, took 1.1%, and Democrat Matt Schultz (8.1%) dropped out. https://www.adn.com/politics/2026/08/28/alaska-election-officials-count-more-ballots-growing-peltolas-lead-in-closely-watched-us-senate-race/
- [2026-10-07] Sabato's Crystal Ball's stated reasons for Leans Democratic (via Juneau Independent): Peltola's favorability is about 50% in two polls, and Sullivan's fell from 47% to 42%. The Crystal Ball also noted her primary margin of about 8 points. https://www.juneauindependent.com/post/peltola-sullivan-moves-to-leans-democratic-at-rating-site-while-new-poll-shows-her-lead-shrinking
- [2026-10-07] Sabato's text, as quoted in search snippets (the page returned 403): Peltola is the only Democrat on the ballot. The three Republican-side candidates split the other vote, and the "fake" Dan Sullivan may draw some low-information incumbent voters. The same text says Peltola also cleared 50% in the 2024 primary but lost the final ranked-choice round by a little over 2 points, which is the counter-argument. https://centerforpolitics.org/crystalball/four-rating-changes-headlined-by-alaska-senate-moving-to-leans-democratic/
- [2026-10-11] The new InsiderAdvantage poll (50-48 after ranked-choice) is a non-partisan-affiliated pollster's result. Peltola has led final-round tallies in the Fabrizio/Impact AARP poll (53-47), ASR Oct 1-3 (51-49 in round three, per Political Wire) and ASR Sept 10-12 (52-48, per RCP). RCP lists all of these as likely-voter polls. https://www.realclearpolling.com/polls/senate/general/2026/alaska/peltola-vs-sullivan
- [2026-09-11] The AARP poll's sponsors are a bipartisan pair (Fabrizio Ward is a Republican firm, Impact Research is Democratic). It found Sullivan leads among voters 50+ only 54-46 in the final round, yet Peltola still wins overall. That means her lead does not depend on a young electorate. https://www.aarp.org/government-elections/alaska-election-poll-2026/
- [2026-07-01] Cook's race page says Peltola is "well-positioned" as the only Democrat on the ballot. It also says Republicans are unsure how to handle ranked-choice options and the second Dan Sullivan, which is a structural split-vote advantage. Cook moved the race from Lean R to Toss Up on July 1. https://www.cookpolitical.com/senate/race/488531
- [2026-07-16] Money: Peltola raised $6.9M in Q2 against Sullivan's $2M+ (his campaign says $3M+ across committees). Her donations average about $50 each, and most come from outside Alaska. Sullivan holds the cash-on-hand edge, so the YES case is about volume of advertising, not parity. https://alaskapublic.org/news/politics/washington-d-c/2026-07-16/peltola-vastly-outraises-sullivan-in-alaskas-u-s-senate-race
- [2026-04-14] Senate Majority PAC is already spending for Peltola, while the Senate Leadership Fund planned $15M for Sullivan. Outside money therefore partly offsets her fundraising edge. https://alaskapublic.org/news/politics/2026-04-14/peltola-announces-big-fundraising-haul-signaling-an-expensive-senate-race-in-alaska
- [2026-10-06] Cook's Senate-control framing (July 1, via DSCC): Democrats' path to a majority runs through Ohio, Alaska, Maine and North Carolina. Alaska is a core piece of the national Democratic strategy, which supports continued late spending. https://www.dscc.org/article/new-alaska-senate-race-shifts-towards-peltola-as-democrats-move-within-striking-distance-of-majority/
- [2026-10-12] The most likely YES path requires four things. (1) Her 49.5% primary share holds in a higher-turnout November. (2) Second-choice votes from Dan J. Sullivan and Heikes, about 8% combined on first choice per ASR, split roughly evenly or leak to her, as ASR's owner says. (3) The Sept 23 NYT conduct story and the unverified Oct 10 slur allegation don't move late voters. (4) The D+8 national environment (DDHQ, Sept 25) offsets Trump's Oct 13 rally and Vance's visit. That would give a final-round margin of roughly 2 to 6 points, in line with the ranked-choice polls.
- [2026-10-12] Counter-risk from the 2024 precedent: Peltola cleared 50% in the 2024 primary and lost by about 2 points in the final round (Sabato). Her current polling lead is no larger than that cushion. The 15-day ballot-count window (Division of Elections pamphlet) means a close race will probably not be called by AP, Fox and NBC on Nov 3-4. https://www.elections.alaska.gov/election/2026/General/OEPbooks/2026%20Alaska%20General%20VP_Region%203_ENG_web.pdf
BOTTOM LINE: The strongest YES case is a consistent final-round polling lead of about 2 to 6 points from mixed sponsors, a near-50% primary in higher turnout, a favorable ballot structure and money advantage, and Sabato, DDHQ (about 60%+) and Cook (Toss-up, "well-positioned") all treating her as the slight favorite. The YES path is that the primary result carries into November, unlike 2024, with Peltola winning the final ranked-choice round by a few points.
NOT FOUND: Q3 FEC totals (due Oct 15). Any AP, Fox or NBC race call. A fetchable Sabato page (403). The InsiderAdvantage poll page itself. A confirmed general-election certification date; the pamphlet only says certification cannot happen before the 15th day after the election.
report: no case
YES means: Mary Peltola is declared the winner of the 2026 Alaska U.S. Senate election, with AP, Fox and NBC all calling it for her or, failing that, official certification showing her as winner.
- [2026-10-09] Dan S. Sullivan has never lost a statewide race. Newsweek notes he was underestimated in parts of the 2020 cycle before beating independent Al Gross. Democrats have not won an Alaska Senate race since 2008, so status quo inertia favours NO. Trump also called for ranked-choice repeal in the November vote (Truth Social, Oct 9) and endorsed Sullivan. https://www.newsweek.com/trump-rages-at-alaska-republicans-over-three-way-race-how-stupid-are-we-12544803
- [2026-10-09] The Peltola lead is thin in first-choice terms. Alaska Survey Research (Oct 1-3, n=1,512) has first-round Peltola 47, Sullivan 45, Dan J. Sullivan Jr. 5, Heikes 3. The NYT/Siena +7 comes from n=504 with a ±5.1 margin, and it is the outlier. In the RCP table, the other pollsters give Peltola +2, Sullivan +1 and Sullivan +3. https://www.newsweek.com/trump-rages-at-alaska-republicans-over-three-way-race-how-stupid-are-we-12544803
- [2026-10-05] The Alaska Division of Elections' target certification date is Nov 25. Ranked-choice tabulation is on Nov 18 and the questioned-ballot board starts Nov 5. A race this close is therefore unlikely to be called on election night. Resolution would come either from the AP, Fox and NBC calling the race for the same candidate, or from certification. A split or late call is only a delay, since certification is far inside the Jul 31, 2027 backstop. A recount or litigation could push things out, but nothing found suggests it would reach 2027. https://alaskapublic.org/news/politics/elections/2026-10-05/what-to-know-about-alaskas-general-election
- [2026-10-05] The Division's pamphlet says certain ballots are counted on the 15th day after the election, so certification cannot happen before then. Late-counted absentee and rural ballots have historically been the ones that moved results, as in the Peltola–Begich 2024 House race. https://www.elections.alaska.gov/election/2026/General/OEPbooks/2026%20Alaska%20General%20VP_Region%204_ENG_web.pdf
- [2026-10-12] Ballot Measure 2 would repeal ranked-choice voting. The 2024 repeal failed by 0.24%, about 737 votes of 320,985 cast. Most Alaska Senate polls report the margin after ranked-choice reallocation. If the repeal passed, it would take effect after this election. This is a structural uncertainty, but the measure is not expected to change this race's rules. https://alaskabeacon.com/2026/07/29/alaskans-to-vote-on-ballot-measure-that-would-overhaul-state-election-system/
- [2026-10-08] Trump's Wasilla rally (Oct 13) comes after Vance's Fairbanks visit. The RNC calls Sullivan "the firewall". Wasilla is one of the most Republican parts of the state. Two White House visits in about a week signal that GOP resources are going into the state, which could mobilise Republican turnout in a lower-turnout midterm. https://alaskapublic.org/news/politics/elections/2026-10-08/trump-to-rally-for-sullivan-in-wasilla-next-week
- [2026-09-17] The AARP poll's older-voter split favours Sullivan. Voters 50+ back him 49-42 on first choice and 54-46 in the final round, and the poll notes older voters turn out more. A midterm electorate skewed old and male would erode Peltola's lead. https://www.aarp.org/government-elections/alaska-election-poll-2026/
- [2026-10-12] Cook still rates the race a Toss-up, and The Hill's Oct 12 weekly piece repeats that. Only Sabato (Leans D) and DDHQ (slight Peltola favourite) lean her way. So the forecaster consensus does not point to a clear Peltola win. https://thehill.com/newsletters/this-week-on-the-hill/6139807-midterm-elections-debates-trump-alaska
- [2026-10-09] In its Oct 9 piece, Newsweek says Polymarket gave the Democrat a 77% chance in the governor's race, a separate contest. That is not a Senate price, but it shows the market is bullish on Democrats in Alaska generally. Prediction-market optimism and the "blue wave" narrative are already priced in, so any narrative shock is asymmetric against Peltola. https://www.newsweek.com/trump-rages-at-alaska-republicans-over-three-way-race-how-stupid-are-we-12544803
- [2026-10-12] The Dan J. Sullivan Jr. confusion is a real NO-side mechanism. The Newsweek Oct 9 piece says Trump called him a Democratic "plant" and urged voters to "vote for the guy with the S". A Republican ballot-name mix-up or a split in the Republican vote could matter. But the ASR owner says the minor candidates' second choices split roughly evenly (earlier report), so this has limited upside for Sullivan. https://www.newsweek.com/trump-rages-at-alaska-republicans-over-three-way-race-how-stupid-are-we-12544803
- [2026-10-12] The race is polarised and low-margin, and the August primary gap of 49.5 to 41.4 overstates general-election strength. A primary electorate is not the November electorate, and the Republican share in the primary was split with minor candidates. Primary first-choice shares of the other two Republicans (about 2.5% for one) are small, so the real swing voters are the 2-8% undecided. https://en.wikipedia.org/wiki/2026_United_States_Senate_election_in_Alaska
BOTTOM LINE: The strongest NO case rests on Alaska's R+13 baseline, a Peltola lead of only about 1-3 points in most polls, the Trump/Vance push, older-voter turnout, and unresolved conduct allegations; Cook still says Toss-up. Deadline arithmetic gives NO no help: certification is targeted for Nov 25, well before Jul 31, 2027, so a delayed call does not produce "Other" unless there is an extraordinary dispute.

(0) Nothing is resolved yet. The election is November 3, 2026, and AP, Fox and NBC have made no call. Alaska's ranked-choice tabulation is scheduled for about November 18, with certification targeted for November 25. That falls far inside the July 31, 2027 backstop, so 'Other' is negligible. (a) About three weeks remain to Election Day. Early voting starts October 19, and resolution could take until late November. (b) If today's polling holds, Peltola wins the final ranked-choice round by roughly 1–3 points. The evidence: RCP average +1.2, DDHQ average +2.5, InsiderAdvantage 50–48 (Oct 11), ASR 51–49, AARP 53–47, NYT/Siena +7. Sabato has moved the race to Lean D, DDHQ gave her just over 60% (Sep 25), and the national environment is about D+8. (c) NO scenario: Alaska's R+13 lean reasserts itself. The Trump rally (Oct 13) and Vance visit drive turnout among older Republicans, the conduct and slur stories erode her support, and polls overstate Democrats as they did in 2024, when Peltola cleared 50% in the primary yet lost the final round by about 2 points. (d) YES scenario: her 49.5% primary share carries into a high-turnout November. As the only Democrat she faces a split Republican field, outraises Sullivan heavily, and the blue national environment lets her win the final round by 2–6 points. The Polymarket anchor is 72.5%, and the Sullivan contract at 28.5% is consistent with it. Models (DDHQ about 60%) and Cook's Toss-up rating sit below the market, and Alaska has a record of polling misses against Democrats, so I shade modestly down to 0.67.

(0) Not resolved: the election is Nov 3 and no call exists; certification is targeted for Nov 25, so the Jul 2027 'Other' fallback is very unlikely. (a) About 3 weeks to Election Day, plus roughly 2 weeks of ranked-choice tabulation. (b) Status quo: Peltola leads by about 1–3 points in averages (RCP +1.2, DDHQ +2.5) and in most final-round polls (InsiderAdvantage 50–48, ASR 51–49, AARP 53–47, NYT/Siena +7), with three Republican-leaning polls showing Sullivan narrowly ahead; Sabato Lean D, Cook Toss-up, DDHQ about 60%. (c) NO: Alaska polls overstate Democrats again, as in 2020 and in 2024 when Peltola cleared 50% in the primary but lost by about 2; Trump's Oct 13 rally and older midterm turnout lift Sullivan; the conduct stories bite. (d) YES: the D+8 environment, low Trump approval, her near-50% high-turnout primary, a money edge and being the sole Democrat yield a 2–5 point final-round win. Anchored on the market's 72.5%, I shade down to about 65% because the historical polling error is comparable to her lead and the model/rating consensus sits around 60%.
