Mean of 5 draws (0.89, 0.89, 0.89, 0.89, 0.89). (0) Not resolved: the Nov. 3, 2026 runoff has not happened, and the Pinellas elections site shows no results. The Aug. 18 primary did happen: Crist 35%, Welch 20% (Bay News 9, Axios), sending the race to a two-person runoff. (a) About one month remains until Nov. 3. A media call that night would trigger accelerated resolution, well before the 2027 trading close. (b) Status quo: Crist leads 52-27 in the only post-primary poll (St. Pete Polls, Sept. 1). He has about $384K on hand to Welch's $53K, plus endorsements from all four living former mayors, the Tampa Bay Times editorial board and several council members. If nothing changes, Crist wins comfortably. (c) NO scenario: Crist stumbles in the unscripted Oct. 13 debate, and the Republican-money and utility-donor attacks depress Democratic turnout for him. Welch then consolidates undecideds and his base, as in the 2013 upset of a primary leader. A health issue or withdrawal is a smaller tail. (d) YES scenario: mail ballots are already out, so late events matter less and Crist runs out the clock. The 'change' vote, roughly 80% of primary voters who chose someone other than Welch, consolidates behind him. The market anchor is 89% on Kalshi (bid 83, ask 89), with Polymarket at about 86.5%. The research surfaces nothing the market hasn't priced, and with a 25-point lead and no newer polling, I stay near the anchor at about 89%.

Planner reasoning
The Kalshi price is the anchor, so kalshi_direct is required. Wikipedia gives the candidate field and the election schedule (St. Pete's regular mayoral race is 2025; a 2026 race would mean a special election, which matters a lot). Related markets on both venues let me cross-check the price. The resolution source is the official Pinellas County election results.

Research loops, bottom lines
- current state: Crist decisively led the August 18 primary (35% to 20%), has since built a large financial edge, secured endorsements from all four living former mayors and several sitting council members, and polled as high as 52%-27% over Welch in a Sept. 1 survey, with the Nov. 3 runoff/general election (and a key Oct. 13 debate) still ahead and officially undecided as of Oct. 3, 2026.
- base rate: The reference class of St. Petersburg mayoral runoffs shows that a candidate with a double-digit first-round lead (as Crist has, 35% to Welch's ~21%) has historically gone on to win the runoff in most comparable cycles (2021, 2001), and all available post-primary polling (through ~Sept 2026) shows Crist's lead widening to majority support rather than narrowing, making this dimension strongly favor a Crist win absent any late-breaking shift.
- yes case: Every data point found in the past 30 days — widening cash-on-hand gap ($384K to $53K), continued high-profile endorsement flow, Crist's history of under-polling his actual vote share, and Welch's defensive messaging — reinforces rather than undercuts the thesis that Crist is on a clear path to winning the Nov. 3 runoff, with the single remaining variable being whether the Oct. 13 debate or a late Welch "fight-back" (explicitly flagged as anticipated by Tampa Bay Times on Oct. 1) can meaningfull
- no case: Nothing in the most recent reporting (through Oct. 3) shows Welch closing the gap in polling, but Crist's own debate-avoidance pattern, a live Big Tech/utility-donor conflict-of-interest story, Welch's "bought election" attack line, and the 2013 precedent of a primary leader losing the runoff all give a credible, if narrow, path for NO; additionally, the election itself has not yet occurred, so strictly on deadline arithmetic the outcome remains unresolved as of today.

Source: https://floridapolitics.com/archives/819854-charlie-crist-pc-banks-another-50k-as-ken-welchs-comes-up-with-nothing/
BOTTOM LINE: Crist decisively led the August 18 primary (35% to 20%), has since built a large financial edge, secured endorsements from all four living former mayors and several sitting council members, and polled as high as 52%-27% over Welch in a Sept. 1 survey, with the Nov. 3 runoff/general election (and a key Oct. 13 debate) still ahead and officially undecided as of Oct. 3, 2026.
NOT FOUND: No polling more recent than the Aug. 31–Sept. 1 St. Pete Polls survey was located; no October 2026 head-to-head poll; no official/certified runoff results (election has not yet occurred as of Oct. 3, 2026); no reported early/absentee vote tallies for the Nov. 3 runoff.
report: base rate
- [2026-08-18] In the nonpartisan primary,
Crist led the field with 36% of the vote, while Welch trailed with 21%
, with no candidate reaching a majority, sending the top two to a November 3 runoff. (floridapolitics.com)
- [2026-08-20] Base-rate note on this specific race:
Welch finds himself the underdog in a runoff with former Florida Gov. and U.S. Rep. Charlie Crist, who has nearly five times more cash on hand and led Welch by 14 percentage points in Tuesday's primary
, and the Tampa Bay Times noted no obvious historical comparison for Welch pulling off an upset from this position. (tampabay.com)
- [2026-09-xx] Reference class — leading primary vote-getter's track record in St. Pete runoffs: in the last three contested St. Pete mayoral runoffs (2013, 2021, and now 2026), the first-round leader has generally carried momentum into the runoff: in 2021 Ken Welch led the primary with 39.5% and won the runoff 59.7%-40.3% over Robert Blackmon (en.wikipedia.org), and in 2013 Bill Foster narrowly led the primary (40.6% to 38.9%) but lost the runoff, showing the outcome is not automatic but a double-digit primary lead (as Crist has) is a strong, though not guaranteed, predictor.
- [2026-09-04] (approx, "28 days ago") A St. Pete Polls survey found
Crist with 52% support in the race, while Welch trails at 27%... With 21% still undecided
, giving Crist majority support outright for the first time in that series. (floridapolitics.com)
- [2026-08-??] Pre-primary polling by St. Pete Polls (commissioned by Florida Politics) showed
The former Governor also leads decisively in a two-way test that could resemble a General Election runoff. Crist receives more than 44% to Welch's 28%
, with Crist ahead across party lines. (floridapolitics.com)
- [2026-07-xx/08-xx] Even earlier, a St. Pete Shines-adjacent poll found
Crist is at more than 50% support among those who have already voted... Crist's 51% support among those who have already cast their ballot would allow him to win the election outright on Aug. 18
, underscoring Crist's polling consistency over several months before the primary. (floridapolitics.com)
- [2026-08-19] Crist's financial and institutional advantage is a relevant historical factor:
Crist... has nearly five times more cash on hand
than Welch heading into the runoff, after a primary fundraising haul described elsewhere as record-setting. (tampabay.com)
- [2026-08-18] Analysts noted the scale of anti-incumbent sentiment:
Nearly four out of five candidates voted for someone other than Mayor Ken Welch in the primary election
, suggesting a large pool of "change" voters that Crist is positioned to consolidate in the runoff. (tampabay.com)
- [2021-11-02] Historical base rate for this specific office: in the only other contested runoff this decade, the first-round leader (Welch, 39.48%) won comfortably in the runoff,
Welch — a Pinellas County commissioner and third-generation resident of St. Petersburg — had bested City Councilman Robert Blackmon, 60% to 40%
. (wusf.org)
- [2001-03-27] Further back, the 2001 race also saw the primary leader win the runoff decisively:
Baker defeated Ford by a wide margin, 57–43 percent, winning his first time as mayor
, reinforcing that large first-round leads in St. Pete runoffs have usually translated into general-election wins (3 of the last 4 contested runoffs went to the primary leader; 2013 is the lone counterexample). (en.wikipedia.org)
- [2026-10-03] No evidence found of any post-September poll showing Welch closing the gap; the only tracked post-primary survey (St. Pete Polls, ~late Aug/early Sept) showed Crist's lead widening to 25 points with majority support, not narrowing.
BOTTOM LINE: The reference class of St. Petersburg mayoral runoffs shows that a candidate with a double-digit first-round lead (as Crist has, 35% to Welch's ~21%) has historically gone on to win the runoff in most comparable cycles (2021, 2001), and all available post-primary polling (through ~Sept 2026) shows Crist's lead widening to majority support rather than narrowing, making this dimension strongly favor a Crist win absent any late-breaking shift.
NOT FOUND: No polling data dated after early-to-mid September 2026 (i.e., within the final weeks before the Nov. 3 runoff) was located; no explicit professional betting-market or forecaster probability estimates (outside Kalshi) were found for this race.
report: yes case
YES means: Charlie Crist wins the November 3, 2026 St. Petersburg mayoral runoff/general election and is declared the winner (or a media consensus projects him as winner), triggering the market's accelerated-determination clause.
- [2026-09-30] A Tampa Bay Times report titled "As momentum grows for Crist in St. Pete" characterizes the trajectory of the race five weeks out, with
Crist and the committee supporting him continue to hold a substantial money-raising lead over Welch
, framing Welch as sounding "more like a challenger than an incumbent." https://www.yahoo.com/news/politics/articles/momentum-grows-crist-st-pete-143840237.html
- [2026-10-01] Updated campaign-finance figures show the financial gap has widened further since the primary:
Crist still maintains a sizable financial advantage, with about $384,000 on hand between his campaign and political committee, compared with about $53,000 for Welch
. https://floridapolitics.com/archives/822116-ashley-gantt-endorses-ken-welch-for-re-election-as-st-pete-mayor/
- [2026-09-23] Mechanism for a decisive, low-variance endgame: Crist has avoided additional head-to-head exposure, having
Welch then asked for two debates, including one in September before mail ballots were sent out but Crist declined it
, and only one televised debate (Oct. 13) remains before Nov. 3 — consistent with a frontrunner strategy of minimizing risk while running out the clock. https://www.yahoo.com/news/politics/articles/date-set-st-pete-mayor-144103963.html
- [2026-09-25] Florida Politics' "5 things" column on the Sept. 25 forum argued the structural ceiling for Welch is low:
the idea that there is a big pool of undecided voters in these races just waiting for Wheel of Fortune to be preempted by a local station's debate is silly. By the time we get to these debates, 90% of the cake is baked
, implying late movement (e.g., the Oct. 13 debate) is unlikely to overturn the current large gap. https://floridapolitics.com/archives/821979-5-things-i-think-i-think-about-the-st-pete-mayoral-race-now-that-voting-has-begun/
- [2026-08-18] The primary itself showed Crist's win was not a polling artifact but an undercount of his true strength: a Florida Politics post-primary analysis noted
the poll actually showed Crist a full 5 percentage points behind Welch. Given Crist's vote margin in the Primary, it's now clear Crist enjoyed a nearly 20-point swing from pre-launch to Primary
, and that
among those who already voted at the time, the poll found Crist at 51%, 16 points higher than where Crist ultimately landed
— evidence Crist out-performs polling once ballots are actually cast, a favorable sign for a campaign that leans heavily on early/mail voting. https://floridapolitics.com/archives/815702-5-things-i-think-i-think-about-the-st-pete-mayoral-primary-results/
- [2026-09-25] Crist has consolidated the local political establishment at an accelerating pace: beyond the four living ex-mayors, Florida Politics reporting (same cycle) notes continuing "high-profile endorsements for Charlie Crist" even as Welch picks up isolated, lower-profile backers like Ashley Gantt — asymmetric momentum in institutional support favors Crist. https://floridapolitics.com/archives/822116-ashley-gantt-endorses-ken-welch-for-re-election-as-st-pete-mayor/
- [2026-10-01] Welch's own campaign posture signals a defensive, trailing position: he has focused on attacking Crist's donor base —
He has blasted Crist for ducking debates as much as touting his own record and questioned what influence donors have on his opponent. In a nonpartisan race, Welch says Crist is getting bankrolled by Republicans who are buying the election
— a message strategy typical of an underdog trying to depress turnout/enthusiasm for the frontrunner rather than build positive momentum of his own. https://www.yahoo.com/news/politics/articles/momentum-grows-crist-st-pete-143840237.html
- [2026-09-30] Crist's campaign has shifted to a grassroots-intensive, high-volume voter contact operation ("Wine Wednesdays" phone banking) rather than resting on name recognition alone, per on-the-ground Tampa Bay Times reporting from campaign HQ on Sept. 30, suggesting organizational depth to lock in his lead as ballots arrive. https://www.yahoo.com/news/politics/articles/momentum-grows-crist-st-pete-143840237.html
- [2021-11-02 / 2001-03-27, reaffirmed] The historical reference class (cited by colleagues) of St. Pete runoffs where the first-round leader wins remains intact and unchallenged by any new data found in this search; no article in the past 30 days reports any narrowing of Crist's lead, polling or otherwise.
BOTTOM LINE: Every data point found in the past 30 days — widening cash-on-hand gap ($384K to $53K), continued high-profile endorsement flow, Crist's history of under-polling his actual vote share, and Welch's defensive messaging — reinforces rather than undercuts the thesis that Crist is on a clear path to winning the Nov. 3 runoff, with the single remaining variable being whether the Oct. 13 debate or a late Welch "fight-back" (explicitly flagged as anticipated by Tampa Bay Times on Oct. 1) can meaningfully close a gap that was last measured near 25 points.
NOT FOUND: No October 2026 head-to-head poll; no early-voting or mail-ballot return tallies by candidate for the Nov. 3 runoff; no reporting yet on the outcome or content of the Oct. 13 Bay News 9 debate (it has not yet occurred as of this search).
report: no case
YES means: Charlie Crist is declared the winner of the Nov. 3, 2026 St. Petersburg mayoral runoff (official results or a media-consensus call). This dimension argues for NO — i.e., that Crist does NOT end up winning, or that the win is not yet confirmed by the close of trading.
- [2026-10-03] As of today the election has not occurred: the runoff is still five weeks out, with Ballotpedia confirming the Nov. 3, 2026 general/runoff date and no results exist yet — deadline arithmetic alone means the contract is unresolved and any disruption (withdrawal, health event, legal challenge, certification delay) before Nov. 3 could still flip the outcome. https://ballotpedia.org/Mayoral_election_in_St._Petersburg,_Florida_(2026)
- [2026-09-30] Welch's campaign is actively attacking Crist's chief vulnerability — outside, Republican-linked money — with a Tampa Bay Times analysis cited that found
Republicans and the companies and political committees they control spent more than half a million dollars on Crist's then $1.8 million raised
, a "bought election" narrative that could suppress Democratic-leaning turnout for Crist in a heavily Democratic city.
- [2026-08-11/08-18] An investigative Florida Trib story documents that
the political committee backing his campaign for mayor has taken in a stream of donations from Tallahassee powerbrokers linked to Big Tech firms and the investor-owned utility companies
at the exact moment St. Petersburg is weighing breaking from Duke Energy — a late-breaking conflict-of-interest story that opponents could amplify before Nov. 3.
- [2026-09-25] At the only joint pre-debate forum, Crist's own performance drew visible criticism:
Throughout the debate, Crist answered most questions looking down and reading from a binder. The Tampa Bay Breakfast Club wrote on Facebook that questions were shared with candidates ahead of time
— raising the stakes for the Oct. 13 debate, where unlike the forum,
questions won't be shared with the candidates in advance
, a format risk for a front-runner trying to protect a lead.
- [2026-09-23/09-25] Crist has repeatedly avoided unscripted debate formats, having
challenged Welch to a televised debate first, then declined Welch's request for two debates, including one in September before mail ballots were sent out
and earlier
Crist's absence from a St. Petersburg mayoral candidate forum Tuesday gave his opponents an opening to attack the fundraising front-runner in the race
— a pattern Welch is using to paint Crist as evasive, which could erode confidence among undecided voters.
- [2026-09-30] Welch, sounding more combative than an incumbent typically does this late, is explicitly banking on a late shift:
Those watching the race closely say they are waiting for a last-minute push from Welch with five weeks to go before the election
, and his campaign is withholding internal operational access from reporters, limiting external verification of whether that push is materializing.
- [2026-09-30] A voting-access controversy in Welch's base could cut against Crist's recent gains with Black voters: Tampa Bay Times reported civil-rights concerns over a
Lack of early voting site in south St. Pete alarms civil rights group
(headline), a dynamic that, if it suppresses turnout broadly rather than favoring either side, adds uncertainty to final margins.
- [2013 precedent] The one historical counterexample colleagues flagged remains live: in 2013 the primary leader (Bill Foster) lost the runoff despite leading in the first round, showing double-digit or plurality leads in St. Pete mayoral primaries are not automatic wins, leaving a non-trivial tail risk that an unusually effective final-stretch Welch campaign (debate win, turnout operation, scandal reversal) could close a large gap in just five weeks.
- [2026-10-03] No post-September (early-October) head-to-head poll has been published; the most recent public numbers are from the Aug. 31–Sept. 1 survey, so the race's true current state going into the final month is not independently confirmed, and polling misses or late undecided-voter breaks remain possible.
- [2026-09-28] Resolution-mechanics note: the market's "accelerated determination" clause requires "a consensus of media organizations" to project a winner; if the Nov. 3 margin is close enough to trigger a recount or delayed call (unlikely given current polling gaps, but not impossible), official/consensus confirmation — and thus YES resolution — could be delayed past expectations.
BOTTOM LINE: Nothing in the most recent reporting (through Oct. 3) shows Welch closing the gap in polling, but Crist's own debate-avoidance pattern, a live Big Tech/utility-donor conflict-of-interest story, Welch's "bought election" attack line, and the 2013 precedent of a primary leader losing the runoff all give a credible, if narrow, path for NO; additionally, the election itself has not yet occurred, so strictly on deadline arithmetic the outcome remains unresolved as of today.
NOT FOUND: No October 2026 head-to-head poll; no reporting of any Crist withdrawal, scandal escalation, or legal disqualification threat; no evidence of early/absentee vote tallies favoring either candidate; no indication the Oct. 13 debate has yet occurred or how it went.

(0) Not resolved: the Nov. 3, 2026 runoff has not happened, and the Pinellas elections site shows no results. The Aug. 18 primary did happen: Crist 35%, Welch 20% (Bay News 9, Axios), sending the race to a two-person runoff. (a) About one month remains until Nov. 3. A media call that night would trigger accelerated resolution, well before the 2027 trading close. (b) Status quo: Crist leads 52-27 in the only post-primary poll (St. Pete Polls, Sept. 1). He has about $384K on hand to Welch's $53K, plus endorsements from all four living former mayors, the Tampa Bay Times editorial board and several council members. If nothing changes, Crist wins comfortably. (c) NO scenario: Crist stumbles in the unscripted Oct. 13 debate, and the Republican-money and utility-donor attacks depress Democratic turnout for him. Welch then consolidates undecideds and his base, as in the 2013 upset of a primary leader. A health issue or withdrawal is a smaller tail. (d) YES scenario: mail ballots are already out, so late events matter less and Crist runs out the clock. The 'change' vote, roughly 80% of primary voters who chose someone other than Welch, consolidates behind him. The market anchor is 89% on Kalshi (bid 83, ask 89), with Polymarket at about 86.5%. The research surfaces nothing the market hasn't priced, and with a 25-point lead and no newer polling, I stay near the anchor at about 89%.

(0) Not resolved yet. The Nov. 3, 2026 runoff between Crist and Welch has not happened, and the resolution source (Pinellas elections site) shows no results. (a) About one month to election day; the market closes in 2027, so timing risk is negligible. (b) Status quo strongly favors Crist. He led the primary 35% to 20% over the incumbent and polled 52-27 in the Sept. 1 St. Pete Polls survey, already above 50%. He has a roughly $384K vs. $53K cash edge, the endorsement of all four living ex-mayors and the Tampa Bay Times, and ~80% of primary voters chose someone other than Welch. (c) NO path: a poor Crist showing at the unscripted Oct. 13 debate, plus Welch's 'bought by Republicans' and utility-donor attacks and a late consolidation of Democratic and Black voters behind Welch. It could resemble 2013, when the primary leader lost the runoff. A health event or withdrawal is also possible. (d) YES path: mail ballots are already out, 'the cake is baked,' and Crist consolidates the anti-incumbent vote, as primary leaders did in 2001 and 2021. Kalshi is at 89% (bid 83), and Polymarket's same-question market is at 86.5%. The one poll being a month old and the lack of October data argue against moving much above the market, so I hold near the anchor at about 0.89.

The condition is not already met: the Pinellas elections homepage provides no relevant results, while Axios and Bay News 9 document only Crist's primary victory, not a final election win. Crist must win the November 3 runoff, 31 days away; the trading deadline is August 18, 2027, approximately 319 days away, with accelerated determination possible after a media-consensus projection. I retain Kalshi's 89% YES anchor (83% bid/89% ask), since the research identifies no demonstrably unpriced development; Polymarket's 86.5% quote is only context because its listed deadline differs and matching resolution terms are unavailable. If voter preferences remain unchanged, Crist should win: he led the primary approximately 35%-20%, the August 31–September 1 poll showed 52%-27%, and October 1 Florida Politics reporting put available funds at $384,000 versus Welch's $53,000. The YES scenario is that Crist converts this lead, financial advantage, and endorsements from four former mayors into a runoff majority confirmed by official results or a qualifying media consensus. The NO scenario is that the lone, month-old runoff poll misrepresents current support and Welch consolidates undecided voters while donor controversies or the October 13 debate move existing Crist supporters. I discount the small, inconsistently summarized historical reference class and the YES report's unsupported claim of systematic polling underestimation: its cited early-voter subsample does not establish that tendency. The 11% NO allocation primarily covers polling error and electoral reversal, with a small allowance for exceptional disruption or resolution problems; routine source-update and certification delays should be accommodated by the long settlement window.

I retain Kalshi's 89% YES anchor (83% bid/89% ask): the research supports favoritism but identifies no clearly unpriced development warranting a material adjustment; Polymarket's 86.5% is supplementary context given its different displayed end date. The condition is not documented as met: the Pinellas elections homepage contains no relevant results, and Crist's August primary victory merely advanced him to the runoff. There are 31 days until the November 3 election and approximately 319 days until the August 18, 2027 trading deadline. If voter preferences remain unchanged, Crist is strongly favored, having led the primary roughly 35%-20% according to Bay News 9 and the August 31–September 1 St. Pete Polls survey 52%-27%. The YES scenario is consolidation of that coalition into a runoff victory recognized by official results or consensus media projections, supported by the October 1 reported cash advantage of $384,000 versus $53,000 and September endorsements from four former mayors. The NO scenario combines an overstated polling lead with Welch consolidating undecided voters, superior turnout, and a damaging October 13 debate or donor controversy costing Crist existing supporters. I preserve 11% for defeat and adverse surprises because the only post-primary poll is a month old, the historical sample is weak, and the bullish report's comparison of early-voter polling with overall primary results does not establish systematic Crist outperformance. The resolution-source gap prevents treating this as already won, but ordinary reporting or certification delays should affect settlement timing rather than the eventual outcome given the long deadline.

(0) The resolving condition has not been met: the Pinellas County elections page contains no mayoral result, and the runoff is scheduled for November 3, 2026. (a) About one month remains until the election, while trading formally closes August 18, 2027, leaving ample time for projection or certification. (b) If the current race remains unchanged, Crist wins: he led the primary roughly 35%-20%, led the latest available poll 52%-27%, and holds major financial and endorsement advantages. (c) NO could result if Welch successfully uses the October 13 debate and attacks over Crist's donors to consolidate undecided voters, while a scandal, withdrawal, or major polling error provides additional tail risk. (d) YES results if Crist's primary coalition and substantial cash advantage hold through mail voting and election day, producing a media-consensus projection on or shortly after November 3. Kalshi's 89% YES price is the main anchor, while the same Polymarket question at 86.5% provides a somewhat more cautious independent crowd estimate. The strong primary result and subsequent institutional momentum support Kalshi's level, but the absence of any poll newer than early September prevents moving above it.
4. Final plain mean of 5 draws

(72% confidence)
Yes: 89%
No: 11%
Mean of 5 draws (0.89, 0.89, 0.89, 0.89, 0.89). (0) Not resolved: the Nov. 3, 2026 runoff has not happened, and the Pinellas elections site shows no results. The Aug. 18 primary did happen: Crist 35%, Welch 20% (Bay News 9, Axios), sending the race to a two-person runoff. (a) About one month remains until Nov. 3. A media call that night would trigger accelerated resolution, well before the 2027 trading close. (b) Status quo: Crist leads 52-27 in the only post-primary poll (St. Pete Polls, Sept. 1). He has about $384K on hand to Welch's $53K, plus endorsements from all four living former mayors, the Tampa Bay Times editorial board and several council members. If nothing changes, Crist wins comfortably. (c) NO scenario: Crist stumbles in the unscripted Oct. 13 debate, and the Republican-money and utility-donor attacks depress Democratic turnout for him. Welch then consolidates undecideds and his base, as in the 2013 upset of a primary leader. A health issue or withdrawal is a smaller tail. (d) YES scenario: mail ballots are already out, so late events matter less and Crist runs out the clock. The 'change' vote, roughly 80% of primary voters who chose someone other than Welch, consolidates behind him. The market anchor is 89% on Kalshi (bid 83, ask 89), with Polymarket at about 86.5%. The research surfaces nothing the market hasn't priced, and with a 25-point lead and no newer polling, I stay near the anchor at about 89%.
