final rationale
Mean of 2 draws (0.91, 0.92). (0) The race is not resolved. The election is Nov 3, 2026, and no AP, Fox or NBC call exists. YES requires Republican Kurt Alme to win a plurality, with no runoff. (a) About 20 days remain before the election, and absentee ballots are already out. (b) Status quo favours YES. Every public poll has Alme ahead by 8–20 points in the four-way field: Rutgers-Eagleton/MTFP +8, Aspect +12, Quantus +20, American Pulse +19. The RCP average is +14 and FiftyPlusOne is +16. Cook rates it Solid R and Sabato reportedly moved it to Safe R on Oct 6. (c) NO: the Oct 12 resignation of the Democratic chair and her endorsement of Bodnar trigger a late Democratic collapse toward the independent. A bad national GOP environment (Polymarket has Democrats at 63.5% for Senate control) adds defections, and Bodnar's money edge (about $4M against Bankhead's roughly $180K) lets him overtake Alme's low-40s share. On paper, Aspect's numbers with Bankhead's vote moved over imply roughly a tie. (d) YES: Bankhead stays in and keeps drawing 12–19%, partly from votes already cast. Alme holds 42–46% in a state Trump won by about 20, and wins comfortably on a split opposition. The market sits at 92.5%, matching Kalshi's roughly 93¢. The only unpriced information is the Oct 12 chair defection, which has no post-event poll, so I shade slightly below market to 0.91.

Planner reasoning
Polymarket direct gives the price anchor, and the resolution source is the AP/Fox/NBC race calls. Kalshi and Polymarket related markets give cross-venue triangulation on the Montana Senate race and Senate control. The Wikipedia page on the 2026 Montana Senate race gives the nominees, any independent candidate dynamics (the Tester/Osborn-style independent matters, since independents don't count as Democrats), and polling.

Research loops, bottom lines
- current state: Alme (R) leads all public polling and is rated Solid R by the major forecasters. The main risk is a consolidating independent, Bodnar, who has Democratic establishment endorsements, strong fundraising and a Democratic chair who endorsed him. The latest poll still shows Alme leading by about 19 points with Bodnar and Bankhead splitting the opposition. No resolution-source call exists yet, and the election is Nov 3.
- base rate: Montana is a deep-red state, with Republicans winning every statewide race since 2020 and ratings at Solid R. Alme leads by double digits in the one public poll I found, and the opposition is split. The main risks are a consolidated independent challenge by Bodnar and a bad GOP environment.
- yes case: The strongest path to YES is the default one. Alme keeps roughly 40–45% of a four-way field while Bodnar and Bankhead split the remainder, which is what every poll and the Cook and Sabato Safe-R ratings imply. The prerequisites are that Bankhead stays on the ballot and keeps drawing Democratic votes (early voting is under way), and that GOP turnout holds despite a poor national environment.
- no case: The NO case needs near-total consolidation of the anti-Alme vote behind Bodnar in the last three weeks, on top of a bad GOP environment. The Oct 12 defection of the Democratic chair is real, but every public poll through mid-September and late September has Alme ahead by 8–20 points. The only tie scenario is a partisan-funded May head-to-head.

report: current state
- [2026-10-12] Alme is the Republican nominee. The Daily Montanan reports that the four-way Senate debate in Bozeman on Oct 11 included Alme (R), Bankhead (D), Bodnar (I) and Austin (L). Alme, the frontrunner, had declined earlier invitations. The same article says Bankhead trails Bodnar in many polls, Bodnar has consistently outraised all candidates, and Austin polls in single digits. https://dailymontanan.com/2026/10/12/montana-us-senate-candidates-share-debate-stage/
- [2026-10-12] Daily Montanan headline: the Montana Democratic Party chair stepped down and endorsed independent Bodnar. NonStop Local also lists a story that Shannon O'Brien stepped down as chair. I read headlines only, not the full article. https://dailymontanan.com/2026/10/12/montana-us-senate-candidates-share-debate-stage/
- [2026-09-28, updated 10-05] American Pulse Research & Polling for NonStop Local (Sept 19–24): Alme 45.1%, Bodnar 26.1%, Bankhead 18.9%, a 19-point Alme lead. 43% say Montana is headed in the right direction and 38.7% the wrong direction. American Pulse is a Republican-leaning firm (per Daily Montanan, Feb 2026). https://www.montanarightnow.com/elections/montana-senate-race-kurt-alme-tops-bodnar-and-bankhead-in-new-poll-findings/article_cd8401fb-0470-492c-a53a-c7dfe39552ff.html
- [2026-10-06] Cook Political Report lists MT-OPEN as Solid R in its Oct 6 Senate ratings. The Cook page lists all Solid R seats (including MT) with none in Likely R or Lean R. https://www.cookpolitical.com/ratings/senate-race-ratings
- [2026-06-25/06-30] Inside Elections rated the race Solid R (updated June 25) after a poll showing Alme favored but polling consistently below 50%. Trump won Montana with 58% in 2024, and the 2026 national environment was described as worsening for the GOP. https://insideelections.com/montana-senate-new-poll-confirms-gop-edge/
- [2026-03/04] Ballotpedia (March 2026 snapshot): Cook Solid R, Inside Elections Likely R, Sabato Likely R, DDHQ pending. Another source, dated 2026-10-12, says Sabato and Inside Elections are now Safe/Solid R. I did not verify this on Sabato's own page. https://ballotpedia.org/United_States_Senate_election_in_Montana,_2026
- [2026-06-02] Primaries: Alme won the GOP nomination with 76.2%. Bankhead won the Democratic nomination with 43.7%. Daines withdrew minutes before the filing deadline and endorsed Alme. Bodnar, an independent backed by Jon Tester, qualified for the ballot. Libertarian Kyle Austin is also on the ballot. https://en.wikipedia.org/wiki/2026_United_States_Senate_election_in_Montana
- [2026-09-22] A Montana Free Press poll found Sen. Sheehy at 43% approval and 47% disapproval, and voters disapproving of the state's direction. This is a sign of some anti-incumbent mood. https://montanafreepress.org/2026/09/22/montana-voters-disapprove-state-direction-and-officials/
- [2026-10-12] Kalshi, a sibling venue, was reported at Alme 93¢ and Bodnar about 6–7¢. The source is a third-party aggregator and may be stale. https://predictionmarketspicks.com/midterms-2026/montana-senate
- [2026-10-14] The Montana general election is Nov 3, and absentee ballots have been mailed (NonStop Local video listing). An NBC News primary-results page exists, so NBC, one of the three resolution sources, will carry results. https://www.nbcnews.com/politics/2026-primary-elections/montana-senate-results
- [2026-10-14] A NonStop Local headline, "Group responsible for $3 million to Democrat in Montana Senate race pulls support," is unverified in detail. Daily Montanan says Bankhead won her primary with millions in progressive dark-money and GOP PAC help. https://www.montanarightnow.com/elections/montana-senate-race-kurt-alme-tops-bodnar-and-bankhead-in-new-poll-findings/article_cd8401fb-0470-492c-a53a-c7dfe39552ff.html
BOTTOM LINE: Alme (R) leads all public polling and is rated Solid R by the major forecasters. The main risk is a consolidating independent, Bodnar, who has Democratic establishment endorsements, strong fundraising and a Democratic chair who endorsed him. The latest poll still shows Alme leading by about 19 points with Bodnar and Bankhead splitting the opposition. No resolution-source call exists yet, and the election is Nov 3.
NOT FOUND: Any independent (non-GOP-leaning) public poll from the last 30 days. Sabato's current rating from its own page. Full text of the Democratic chair endorsement story. Any AP, Fox or NBC call, which is expected since the election has not happened.
report: base rate
- [2026-11-03] The election is on Nov 3. The nominees are Kurt Alme (R), Alani Bankhead (D), Seth Bodnar (independent, endorsed by ex-Sen. Tester) and Kyle Austin (Libertarian). Daines withdrew minutes before the filing deadline and Alme was nominated with 76.2% of the primary vote. Only the Republican nominee counts as "Republican" for this market, and Bodnar is excluded as an independent. https://en.wikipedia.org/wiki/2026_United_States_Senate_election_in_Montana
- [2026-10-06] Cook Political Report rates the race Solid Republican. Its Senate ratings were published Sept 23 and the Cook MT page shows Solid R, with an April 27 update. https://www.cookpolitical.com/senate/race/488621
- [2026-06-25] Inside Elections rates it Solid R (updated June 25). Its June 30 article says Republicans are favored despite a worsening national environment and a well-funded independent. Alme polls consistently below 50%. https://insideelections.com/montana-senate-new-poll-confirms-gop-edge/
- [2026-03-31] Ballotpedia's snapshot showed Cook at Solid R, and Inside Elections and Sabato at Likely R. Those Inside and Sabato ratings are older than the June Inside update above. I did not find a current Sabato rating. https://ballotpedia.org/United_States_Senate_election_in_Montana,_2026
- [2026-09-28] A NonStop Local/American Pulse poll (Sept 19–24, a Republican-leaning firm) has Alme at 45.1%, Bodnar at 26.1% and Bankhead at 18.9%. That is a 19-point Alme lead, and the Democrat and independent split the opposition. https://www.montanarightnow.com/elections/montana-senate-race-kurt-alme-tops-bodnar-and-bankhead-in-new-poll-findings/article_cd8401fb-0470-492c-a53a-c7dfe39552ff.html
- [2026-02-24] An earlier American Pulse poll, from when Daines was still the candidate, had Daines at 50.6% against Bodnar's 41.6% in a head-to-head. https://dailymontanan.com/2026/02/24/poll-shows-daines-with-sizable-lead-over-democratic-independent-challengers/
- [2026-10-14] A headline on the NonStop Local page reports a group responsible for $3M to the Democrat pulling support. I did not read the story. Another headline says Democratic Party chair Shannon O'Brien stepped down.
- [2026-09-22] A Montana Free Press poll shows Sen. Sheehy (R) at 43% approve and 47% disapprove. Voters disapprove of the state's direction. https://montanafreepress.org/2026/09/22/montana-voters-disapprove-state-direction-and-officials/
- [2024-11-06] Base rate: Sheehy (R) beat three-term incumbent Tester 52.6% to 45.5% in 2024. Republicans have won every Montana statewide race since 2020. Trump won the state by about 20 points in 2024. https://en.wikipedia.org/wiki/2024_United_States_Senate_election_in_Montana
- [2020-11-03] Daines won in 2020 with 55.0% to 45.0%. The last Montana Senate seat to flip to Democrats was the 2006 Tester win. Republicans held Montana's Class 1 seat in 2000 and flipped it in 2024. https://en.wikipedia.org/wiki/2020_United_States_Senate_election_in_Montana
- [2026-10-12] Other red-state races (ID, SD) are rated Solid or Safe R by most forecasters as of Oct 6–9, while Montana is the one with an independent drawing Democratic backing. Independent precedents: Osborn (NE, 2024) and McMullin (UT, 2022) made races competitive, but neither won. https://en.wikipedia.org/wiki/2026_United_States_Senate_elections
- [2026-10-01] The national environment is reported as worsening for the GOP. Cook moved the MT-1 House race from Likely R to Lean R, which shows some Montana-specific movement. https://montanafreepress.org/2026/10/01/poll-fishing-in-montanas-hottest-house-race/
BOTTOM LINE: Montana is a deep-red state, with Republicans winning every statewide race since 2020 and ratings at Solid R. Alme leads by double digits in the one public poll I found, and the opposition is split. The main risks are a consolidated independent challenge by Bodnar and a bad GOP environment.
NOT FOUND: Current Sabato rating, and any non-partisan or independent public poll of the general election. No Bodnar-versus-Alme head-to-head poll showing a close race. No forecast-model probabilities for Montana, such as Silver Bulletin or The Economist. Polymarket and other markets' prices were deliberately not searched.
report: yes case
YES means: Republican nominee Kurt Alme wins the 2026 Montana U.S. Senate race, as called by AP, Fox and NBC or, failing that, by official certification.
- [2026-10-06] Sabato's Crystal Ball moved Montana from Likely R to Safe R on Oct 6. It made the move in the same update that moved Alaska toward Democrats. Montana was therefore the one seat where a forecaster raised the GOP's odds late. Cook (Oct 6) and the Crystal Ball are now both at Safe/Solid. This is the newest rating action, and it came before the Oct 12 chair endorsement. https://centerforpolitics.org/crystalball/2026-rating-changes/
- [2026-10-12] FiftyPlusOne's poll average is Alme 43.3, Bodnar 27.3, Bankhead 18.5, an Alme lead of 16. RealClearPolling's average (8/27–9/15) is Alme +14. Poliwave's model (polls through 9/15) gives Alme +10.5 and rates the race Likely R. https://fiftyplusone.news/polls/senate/general/montana
- [2026-09] Two other public polls fit this picture. Quantus (9/14–15, likely voters, n=625) had Alme 44, Bodnar 24, Bankhead 23. Rutgers-Eagleton/Montana Free Press (8/27–9/7, registered voters, n=845) had Alme 38, Bodnar 30, Bankhead 16, Austin 5. That is the closest non-partisan poll, and Alme still led by 8. The Rutgers-Eagleton poll is more credible than the American Pulse poll in the earlier reports. https://www.realclearpolling.com/polls/senate/general/2026/montana/alme-vs-bankhead-vs-bodnar-vs-austin
- [2026-10-02] MTPR's Campaign Beat (political scientist Rob Saldin) says no poll has shown Bodnar or Bankhead winning or within striking distance. He says Alme's own 45% is typical for a Montana Republican a month out. The opposition is split, and Saldin says combining Bodnar and Bankhead would "be a different story". https://www.mtpr.org/podcast/campaign-beat/2026-10-02/campaign-beat-new-polling-new-ads-new-challenges
- [2026-10-12] Bankhead publicly refuses to drop out. On Oct 12 she said the ex-chair had worked against the nominee since summer, and that Montanans are already voting. The Montana Free Press reports Bankhead is 14 points behind Bodnar in its September poll. Absentee ballots are out, and Democratic votes are already being cast for Bankhead. So the anti-Alme vote stays split, which is the main path to YES. https://thehill.com/homenews/campaign/6144107-montana-democrats-chair-resigns/
- [2026-10-12] The Oct 12 chair resignation is a sign of Democratic disarray, not proof of consolidation. Bruce Knutson became chair immediately. The chair's message was that Bankhead lacks "momentum, resources or will". But Bankhead's campaign is still on the ballot and its nominee is still fighting. https://nbcmontana.com/news/local/montana-democratic-party-chair-resigns-endorses-bodnar-10-12-2026
- [2026-10-12] Bankhead had raised about $180K by the chair's resignation, against more than $4M for Bodnar (a partisan Substack figure). The Democratic nominee therefore has few resources to attack Alme or to reach voters. Bodnar's own fundraising edge is real, but his money comes from ActBlue and left-leaning PACs. Alme is attacking him as a "Democrat in disguise". https://www.breitbart.com/politics/2026/08/25/exclusive-kurt-alme-montanas-democrat-in-disguise-seth-bodnar-runs-on-liberal-actblue-cash-should-refund-1-76m/
- [2026-08-07] Even Bodnar's own allies' poll shows Alme ahead. The Hart Research poll for Forward Montana had a four-way result of Alme 45, Bodnar 30, Bankhead 15, Austin 6. Bodnar's tie with Alme in that poll came only in a hypothetical head-to-head with Bankhead absent. Alme only loses if a poll-implied consolidation happens before Nov 3. https://forwardmontana.org/results-of-new-polling-on-the-montana-u-s-senate-election/
- [2026-07-16] Alme has the money to compete, with $1.4M cash on hand at the Q2 FEC filing. He has Trump's endorsement. Daines also moved $350K to Alme's joint fundraising committee. Party and outside GOP money is available for a final push. https://dailymontanan.com/2026/07/16/independent-bodnar-again-leads-all-all-candidates-in-latest-fundraising-reports/
- [2026-10-02] The main environment risk is on the House side, not the Senate: the MTPR panel says national conditions are "extremely favorable" for Democrats. That cuts against Alme only if the wave erodes GOP support further. Saldin's Montana-specific point is that the state's long-term GOP trend has accelerated. https://www.mtpr.org/podcast/campaign-beat/2026-10-02/campaign-beat-new-polling-new-ads-new-challenges
BOTTOM LINE: The strongest path to YES is the default one. Alme keeps roughly 40–45% of a four-way field while Bodnar and Bankhead split the remainder, which is what every poll and the Cook and Sabato Safe-R ratings imply. The prerequisites are that Bankhead stays on the ballot and keeps drawing Democratic votes (early voting is under way), and that GOP turnout holds despite a poor national environment.
NOT FOUND: A poll taken after the Oct 12 resignation and debate. A Bodnar-versus-Alme-only poll after August. Q3 FEC numbers for Alme (the due date was around Oct 15). The Sabato page itself could not be fetched, so its Oct 6 Safe R rating comes from the search snippet and PollingSource.
report: no case
YES means: the Republican nominee (Kurt Alme) is the certified or AP/Fox/NBC-called winner of the Nov 3, 2026 Montana U.S. Senate race. This report argues the NO side only, meaning Alme loses to an independent or a Democrat.
- [2026-10-12] Montana Democratic Party chair Shannon O'Brien resigned and endorsed Bodnar. She said Bankhead lacks "the momentum, resources or will to win". The resignation makes Bodnar's pitch to Democratic voters more credible, which is the consolidation mechanism Sabato named as his first hurdle. IVN lists the other Democratic backers: Tester, Bullock, Baucus, VoteVets, the Montana AFL-CIO and Montana Conservation Voters. https://ivn.us/montana-democratic-chair-resigns-endorses-independent-seth-bodnar-for-senate/
- [2026-10-12] The party apparatus under new chair Bruce Knutson formally stays with Bankhead. Bankhead says she is staying in, and ballots are already being cast. Her name therefore stays on the ballot and she keeps taking some opposition votes. That fragmentation helps Alme, so it is a limit on the NO case. https://ivn.us/montana-democratic-chair-resigns-endorses-independent-seth-bodnar-for-senate/
- [2026-05-19] The Tavern Research poll was commissioned by Contours Inc., the group that also funded pro-Bankhead spending and positive messaging for Bodnar, so it is partisan. Of 607 likely voters, Bodnar tied Alme 50-50 head-to-head, and Trump's job approval was 49-49. Bodnar won independents 59-41 in that matchup. This is the only head-to-head showing a tie. The 4-way ballot (Alme 46, Bodnar 26, Neill 24, Libertarian 3) shows the Democrat's presence blocking him. https://tavernresearch.substack.com/p/montana-senate-bodnar-ballot-split
- [2026-09-15] Aspect Strategic (n=715) had Alme 44, Bodnar 32, Bankhead 14. That is a 12-point gap and the highest Bodnar share in any poll. If Bankhead's 14% moved to Bodnar, the race would be close on paper (46-44 for Bodnar). The Montana Free Press/Eagleton poll (Aug 27–Sep 7, registered voters) had Alme 38, Bodnar 30, Bankhead 16, Austin 5. Alme sat below 40% there, with a large undecided pool. https://www.poliwave.com/us/mt/sen-fed
- [2026-09-15] The RealClearPolling average (Aug 27–Sep 15) is Alme 41.0, Bodnar 27.0, Bankhead 19.5, a 14-point lead. Alme is under 45% in the polling average. Bodnar plus Bankhead total 46.5%, which exceeds Alme's share. A NO outcome needs near-total consolidation of non-Alme voters plus a few defectors. https://www.realclearpolling.com/polls/senate/general/2026/montana/alme-vs-bankhead-vs-bodnar-vs-austin
- [2026-07-07] The Progressive Vet PAC, which spent more than $2.5 million on Bankhead's primary win, quit her campaign. It said a Democrat has no viable path. Bankhead had raised under $24,000 herself by mid-May. A nominee with almost no money and no party-committee support means the Democratic vote can break toward Bodnar late. Bodnar also raised the most money and had the most cash in Q1. https://dailymontanan.com/2026/07/07/financial-backer-of-democratic-senate-nominee-backs-out-of-montana/
- [2026-09-23] CNN reported Bodnar claiming momentum, 8 points behind in the Montana Free Press poll. DSCC support for Bankhead was reported absent (Semafor, via NonStop Local, undated, about 81 days before today). A national party that deliberately stays out leaves a consolidated Bodnar bid with little institutional opposition. https://www.cnn.com/2026/09/23/politics/video/inside-politics-seth-bodnar-independent-montana-senate-race
- [2026-03-xx] Sabato moved the seat from Safe R to Likely R when Daines withdrew late. It said Alme faces questions about being anointed by Daines. The Daily Montanan reported that Daines said he picked Alme to pre-empt a more competitive Democrat. Many Republicans, as well as Democrats, objected. This shows some intra-GOP resentment that is not visible in polls. https://centerforpolitics.org/crystalball/late-candidate-switcheroos-contribute-to-rating-changes-in-california-and-montana/
- [2026-06-15] The NYT headline described the seat as vulnerable until the left splintered. That is the best-evidenced reason the opposition is weak, and it works against NO. The structural NO case rests on how late the splintering reversed. The chair's defection came on Oct 12, about three weeks before election day and after the late-September polls. None of the polls in my results post-date it. https://en.wikipedia.org/wiki/Seth_Bodnar
- [2026-10-12] Resolution mechanics: Bodnar is an independent, so he does not count under "Democrat" or "Republican". He wins only if the market resolves NO, because Yes is Alme alone. Montana has plurality voting with no runoff, so Alme in the low-to-mid 40s still wins unless one rival gets above him. A recount or certification dispute is unlikely to matter unless the margin is very thin. https://dailymontanan.com/2026/10/12/montana-democratic-party-chair-steps-down-endorses-independent-us-senate-candidate/
- [2026-10-12] Third-party sites showed Kalshi at Alme 93¢ and Bodnar about 6¢. This is a sibling venue and a third-party snapshot. It implies the market prices the NO tail well under 10%. https://predictionmarketspicks.com/midterms-2026/montana-senate
BOTTOM LINE: The NO case needs near-total consolidation of the anti-Alme vote behind Bodnar in the last three weeks, on top of a bad GOP environment. The Oct 12 defection of the Democratic chair is real, but every public poll through mid-September and late September has Alme ahead by 8–20 points. The only tie scenario is a partisan-funded May head-to-head.
NOT FOUND: Any poll taken after the Oct 12 chair resignation. A Bodnar-versus-Alme head-to-head poll from after the primary. Sabato's current rating on its own page (the search results show Likely R as of the March and April snapshots). Early-vote or ballot-return data for Montana.

(0) The race is not resolved. The election is Nov 3, 2026, and no AP, Fox or NBC call exists. YES requires Republican Kurt Alme to win a plurality, with no runoff. (a) About 20 days remain before the election, and absentee ballots are already out. (b) Status quo favours YES. Every public poll has Alme ahead by 8–20 points in the four-way field: Rutgers-Eagleton/MTFP +8, Aspect +12, Quantus +20, American Pulse +19. The RCP average is +14 and FiftyPlusOne is +16. Cook rates it Solid R and Sabato reportedly moved it to Safe R on Oct 6. (c) NO: the Oct 12 resignation of the Democratic chair and her endorsement of Bodnar trigger a late Democratic collapse toward the independent. A bad national GOP environment (Polymarket has Democrats at 63.5% for Senate control) adds defections, and Bodnar's money edge (about $4M against Bankhead's roughly $180K) lets him overtake Alme's low-40s share. On paper, Aspect's numbers with Bankhead's vote moved over imply roughly a tie. (d) YES: Bankhead stays in and keeps drawing 12–19%, partly from votes already cast. Alme holds 42–46% in a state Trump won by about 20, and wins comfortably on a split opposition. The market sits at 92.5%, matching Kalshi's roughly 93¢. The only unpriced information is the Oct 12 chair defection, which has no post-event poll, so I shade slightly below market to 0.91.

(0) Not resolved. The election is Nov 3, 2026, and AP/Fox/NBC have made no call. (a) There are about 20 days until election day, and absentee ballots are already out. (b) Status quo: Alme (R) leads every public poll. The polling average is roughly Alme 41–45, Bodnar 26–32, Bankhead 15–20, Alme up 8–20, and Montana uses plurality voting with no runoff. Cook and Sabato rate the race Solid/Safe R as of Oct 6, so the default outcome is YES. (c) NO: the Oct 12 resignation of the Democratic chair, who endorsed Bodnar, plus an absent DSCC and a broke Bankhead, triggers late near-total consolidation behind Bodnar. Combined with a strongly anti-GOP national wave and Bodnar's money edge, he edges Alme in a close race. On paper, Bodnar plus Bankhead (about 46%) is already above Alme's average. (d) YES: Bankhead stays in, early Democratic votes are already locked in for her, and the opposition stays split. Alme wins with low-to-mid 40s in a Trump+20 state. The market anchor is 92.5% here and about 93% on Kalshi. The only new information since late September is the chair defection, which partly happened before the current price, and no poll post-dates it. I hold near the market at 0.92, keeping a modest tail for consolidation in a wave year.
