This question asks whether Scott Jennings will be the FIRST new person to become White House Press Secretary after issuance. Karoline Leavitt is the current Press Secretary, so this requires both a vacancy/transition AND Jennings being chosen over other candidates. Key drivers are Leavitt's job security, any reporting of Jennings being considered for administration roles, and how the market prices him relative to alternatives.

# Current state The White House Press Secretary position has been vacant since Karoline Leavitt's departure on 2026-08-27; no permanent replacement has been named as of early September 2026. Scott Jennings is widely reported as an "early favorite" but Trump himself is reportedly "not quite sold," and the administration may not name a permanent pick until after the November 2026 midterms. Kalshi currently prices Jennings at 19% — well below majority, reflecting genuine uncertainty and a crowded field. # Timeline of key events - 2025-01-20: Karoline Leavitt becomes WH Press Secretary (confirmed, Wikipedia). - 2026-08-12: Trump announces Leavitt will leave the role by end of August 2026 (confirmed, NPR). - 2026-08-17: Reports surface Trump considering Fox News's Alexis McAdams as a replacement (reported, Independent). - 2026-08-20: CNN reports Jennings has "emerged as an early favorite," citing a meeting between Chief of Staff Susie Wiles and Jennings; process "just beginning," Trump "not quite sold" (reported, CNN/NOTUS). - 2026-08-21/23: Leavitt reveals her post-WH plans; officially departs (confirmed, NY Post/Fox10). - 2026-08-27: Leavitt's last day; position formally vacant (confirmed, Wikipedia). - 2026-08-27/28: Multiple local Fox affiliates run "Who will replace Karoline Leavitt?" pieces naming Jennings, Anna Kelly, Ari Fleischer, Natalie Harp, Steven Cheung, Alina Habba, Tricia McLaughlin, Stephen Miller (reported, syndicated Fox content). - ~2026-08-28: Alina Habba, previously a Kalshi betting favorite, rules herself out (reported, ABC3340/Fox9). - Late Aug 2026 (unspecified day): Kalshi bettors reportedly gave Jennings 37%, Anna Kelly 22%, per claude_news synthesis — this conflicts with the current kalshi_direct anchor of 19%, suggesting either a snapshot from a different/earlier day or a stale secondary source (unreconciled conflict; primary tool reading of 19% is authoritative for "now"). - 2026-09-01: No formal announcement; 40+ days without a WH press briefing; officials suggest a permanent pick may wait until after the midterms (reported, NBC). # Event Will Scott Jennings be the next White House Press Secretary of the United States (resolves by first person to hold the office after Leavitt's departure)? # Outcomes to forecast Yes / No # Kalshi market anchor Current YES price: **19.00%** (KXNEXTPRESSEC-29JAN21-SJEN). 7-day change: -7.00%. 30-day change: +9.20%. Price range over 29 days: 0.60%–46.00%. Avg daily volume: ~22,317 contracts — high liquidity/attention. Trend: volatile, recent pullback from a peak, but still elevated vs. historical low. # Sub-question answers 1. **Kalshi price/trend** — 19% currently; peaked as high as 46% and dipped as low as 0.60% over the past month; down 7pts in the last week but up 9.2pts over 30 days (kalshi_direct). 2. **Is Leavitt's exit confirmed/secure** — Confirmed departure; she left effective 2026-08-27, ending 19 months in the role, to "spend more time with family" (NPR, Wikipedia). Position is now vacant, not filled on an interim/secure basis. 3. **Jennings' interest/consideration** — Reported as WH's early favorite per CNN, with a Wiles-Jennings meeting; however, Jennings has publicly downplayed it ("I don't know what's going to happen") and Trump is reportedly "not quite sold," though he called Jennings "good" publicly (CNN, NOTUS, TheHill, Yahoo). 4. **Other candidates/implied odds** — Anna Kelly (principal deputy press secretary, "natural successor"), Ari Fleischer, Natalie Harp, Steven Cheung, Tricia McLaughlin, Stephen Miller, and previously Alina Habba (since withdrawn) and Alexis McAdams of Fox News. A secondary source cites Kalshi giving Kelly ~22% at one point vs. Jennings ~37%, though this conflicts with the current 19% anchor (claude_news, unreconciled). 5. **Base rate for outside commentators** — No direct historical precedent cited; code_execution models suggest an outside media figure conditional probability of ~2–10% given a vacancy, yielding a raw base-rate estimate of ~2–9% (well below current market price), reflecting the typical preference for internal deputies/insiders. 6. **Polymarket comparison** — No comparable Polymarket market found (0 matches for "press secretary," "Scott Jennings," "Karoline Leavitt"). # Key facts (high-confidence, factual) 1. [Wikipedia/NPR] Leavitt's tenure ended 2026-08-27; position vacant since. 2. [Kalshi] Current YES price for Jennings is 19%, down from a 46% high. 3. [CNN/NOTUS] Jennings is the most-discussed name but Trump is hesitant; no formal decision made. 4. [NBC] Permanent pick may be delayed until after Nov 2026 midterms. 5. [Fox syndication] Anna Kelly, the sitting principal deputy press secretary, is viewed as the natural internal successor. # Cross-market signals - Kalshi related: "No other person" wins Secretary of State market at 55% (unrelated but shows Kalshi pricing patterns); NATO Sec-Gen market at 8% for Kallas — comparators only, no arbitrage link. - Polymarket: No matching market exists. - Sportsbook implied: None found. # Analyst opinions and speculation - Salon opinion piece frames a Jennings pick as Trump's "final coup" over media — speculative/opinion, not factual signal. - Poynter commentary questions viability of Jennings given his CNN/Salem Radio conflicts and an active defamation lawsuit over a doctored video (Mediaite), which could be a disqualifying risk factor. # Directional lean per outcome - **Yes (Jennings)**: Supported by frontrunner reporting, Wiles meeting, media buzz, Kalshi pricing well above generic base rate (19% vs. ~2-9% naive model). Opposed by Trump's reported hesitation, Jennings' own hedging, pay-cut disincentive, defamation lawsuit exposure, and strong internal candidate (Anna Kelly) as institutional default. - **No (any other person)**: Favored by structural base rates (internal deputies more commonly promoted), uncertainty/delay in timeline (possibly past midterms), wide candidate field, and existing 81% Kalshi-implied "No." # Gaps / unknowns - No information on formal shortlist or interview process status past early Sept 2026. - Unclear which report (37% vs. 19%) is more recent — possible pricing volatility or data staleness; treat 19% as authoritative live anchor. - No detail on interim press secretary arrangement or acting spokesperson currently. - Long resolution horizon (to Jan 2029) leaves ample scope for reversals, additional turnover, or Jennings being passed over. # Calibration anchors - Kalshi current YES price: **19%** (primary anchor). - Model-based base rate (code_execution): ~2–9% for an outside commentator becoming PS absent strong signals; current market prices well above this, reflecting real reported frontrunner status. - Historical PS tenure ~1.3–2 years average — high turnover likelihood ahead of 2029, meaning even if Jennings isn't first replacement, resolution is specifically about the *first* new PS, reducing his path to a single event.

1. Both forecasts converge suspiciously precisely on the Kalshi anchor (18%) without independently grappling with the "first new PS" resolution nuance — the brief notes "Historical PS tenure ~1.3–2 years average... resolution is specifically about the *first* new PS, reducing his path to a single event" — a factor that should push probability down given the ~2.3-year remaining horizon to Jan 2029, yet neither forecaster discusses whether Jennings could win, serve briefly, and still count as "next," versus the risk that someone else is named first and Jennings never gets the title at all. 2. Neither forecaster addresses the unreconciled 37% Jennings/22% Kelly secondary Kalshi snapshot cited in the brief — even dismissing it as stale, they should flag that this discrepancy implies unusual volatility/uncertainty in the market's own self-consistency, which should widen (not narrow) confidence intervals rather than support settling right at the point estimate. 3. Both cite the defamation lawsuit and pay-cut disincentive as headwinds but neither quantifies how disqualifying the "active defamation lawsuit over a doctored video" could be — Poynter's specific viability concern is treated as a minor factor rather than a potential hard bar, which could justify a lower probability than 18%. 4. Neither model seriously engages with the delay scenario ("permanent pick may wait until after the midterms") as a structural risk that events/candidates could shift substantially in the intervening months, given a field of 8+ named candidates (Kelly, Fleischer, Harp, Cheung, Habba-withdrawn, McLaughlin, Miller, McAdams) — this argues for more dispersion in the "No" bucket across time rather than treating current snapshot odds as durable to the 2029 close date. 5. Both forecasters essentially just parrot the market price with a symbolic "slight downward nudge," but given the base-rate model (~2-9%) sits far below market pricing, there's insufficient independent justification given for why the market's 19% (rather than something closer to the base rate) is the right level — they treat the frontrunner reporting as sufficient to bridge that gap without weighing that "early favorite" status historically has low conversion given Trump's noted indecision and the many past instances of front-runners being passed over in this administration. 6. Confidence levels (0.55 and 0.67) are asserted without clear grounding — given the long horizon to 2029 and acknowledged "ample scope for reversals, additional turnover," it's unclear why confidence would be moderate-to-high rather than low, especially since neither rationale explains how confidence was derived from the uncertainty described in their own text.

17% (61% confidence)

Yes: 17% No: 83%

Both forecasts land at the Kalshi anchor (19%) with a slight downward shade to 18%, and the critique doesn't overturn that logic — it mostly argues for modestly more downside. The strongest critique points are valid: the 'early favorite' label has low historical conversion given Trump's indecision, the defamation lawsuit and pay-cut disincentive are real viability risks, and a post-midterms delay in a crowded 8+ candidate field dilutes any single name's chances. However, the liquid market has already digested the frontrunner reporting and Trump's hesitation, so a large deviation toward the ~2-9% base rate isn't justified when specific reporting places Jennings at the top of the list. I settle at 17% Yes, a small additional shade below both forecasters to reflect the delay risk and volatility flagged in the critique.
