Planner reasoning

This is a combination market on the Jul/Sep/Oct 2026 FOMC decisions where 'differently' almost certainly means the 'Other' bucket — any path not among the listed cut/pause combinations, including any hike. Key inputs are the sibling Polymarket combo prices (which must sum to ~1), Kalshi per-meeting FOMC probabilities to build an implied path distribution, and macro/news context on the 2026 rate outlook and new Fed leadership.

# Current state The July 28‑29, 2026 FOMC meeting already occurred: the Fed held its target range at 3.50–3.75% (upper bound 3.75%) on a 9‑3 vote, with three dissents favoring a hike — the most divided vote since 2016. One of the three "decisions" in this market is therefore locked in as a **hold**. Resolution now hinges on whether the Sep 15‑16 and Oct 27‑28 meetings also produce holds (→ "No"/same-three-times) or whether either meeting cuts or hikes (→ "Yes"/Other, since that would make the sequence non-uniform, and any hike automatically forces "Other"). # Timeline of key events - **2026-05-22** (confirmed): Kevin Warsh sworn in as Fed Chair, succeeding Powell; Trump has publicly pushed for cuts, but Warsh has signaled a departure from Powell-era forward guidance (CNBC). - **2026-06 (mid-June FOMC)** (reported): Dot plot turned sharply hawkish — 9 of 19 members projected ≥1 hike by year-end, median 2026 rate projection raised to 3.8%; rate held (Yahoo Finance, TradingKey). - **2026-07-29** (confirmed): FOMC holds at 3.50–3.75% upper bound, 9‑3 vote; Hammack, Kashkari, Logan dissent in favor of a 25bp hike (Federal Reserve official statement). - **2026-07-30** (reported): Forbes/media coverage frames September hike as "most likely outcome" per market pricing. - **2026-08-03/08-09** (reported): Commentary split — some outlets ("no one has witnessed in 56 years") emphasize hawkish repricing; others (Yahoo, Fool) report renewed doubts about a September hike, gold rallying on hike-doubt unwind. - **Upcoming**: FOMC meets Sep 15‑16, 2026 and Oct 27‑28, 2026 — both outstanding. # Event Will the Fed's decisions at the Jul, Sep, and Oct 2026 FOMC meetings differ (not all three identical: cut/pause/hike mix) rather than repeat the same action three times? # Outcomes to forecast Yes (decides differently / "Other" bucket) vs. No (same decision — most likely pause‑pause‑pause — at all three meetings). # Kalshi market anchor No kalshi_direct data was returned for this ticker; the address format (0xd32ac…) indicates this is a **Polymarket** contract, not a native Kalshi series. Primary anchor is therefore Polymarket: **current YES ("differs"/Other) price = 47.5%**, down from a 72.5% high over the 57-day window, 7‑day trend −7.0%, 30‑day trend −3.5%, total volume ~$293k. No Kalshi-listed equivalent combination market was found; only tangential Kalshi series (KXFEDFUNDSYEAR, KXFEDDECISION-28JAN) exist, none pricing this specific 3-meeting-path question. # Sub-question answers 1. **Polymarket price / sibling combos** — Only this market's own price (47.5% for "Other/differs") was retrievable; no sibling cut‑cut‑cut/pause‑pause‑pause markets were found via polymarket_related (0 matches). 2. **Enumerated combinations / hike treatment** — Rules state: qualifying cut/pause/hike per meeting; "Other" is the residual for any combination not separately listed, and explicitly **any hike is automatically bucketed into "Other."** 3. **Kalshi implied per-meeting probabilities** — Not available; no Kalshi per-meeting FOMC markets were returned in research. 4. **Current rate & trajectory** — Fed funds upper bound (DFEDTARU) = 3.75%, effective rate (DFF) = 3.63% as of Aug 2026, unchanged since the July hold; no cuts occurred in H1 2026 per FRED series. 5. **Hike probability given data** — CPI (CPIAUCSL) rising steadily (322→332.6, Jul25–Jun26); PCE core also trending up; unemployment stable/declining slightly (4.5%→4.1%, Nov25–Jul26); 10Y breakeven inflation ~2.25-2.29% (elevated but not runaway). July dissent (3 members) plus hawkish June dot plot (9/19 favor a hike) elevate hike odds; one source cites 76‑82% Sep hike probability (Forbes/bingx) — likely overstated/single-source, treat as reported not consensus. 6. **New leadership effect** — Warsh's departure from forward guidance (no dot submission at first meeting) increases path uncertainty; Trump's public pressure for cuts conflicts with hawkish committee majority, raising odds of an "unusual"/split outcome (claude_news synthesis). 7. **Historical base rates** — Not directly answered in research; no historical three-meeting-sequence frequency data was retrieved. # Key facts (high-confidence, factual) 1. [Federal Reserve, official] July 29, 2026: held at 3.50–3.75%, 9‑3 vote, 3 dissents favoring hike — most divided since 2016. 2. [FRED] Fed funds upper bound = 3.75%, effective = 3.63% (as of Aug 2026); flat since before July meeting. 3. [CNBC] Kevin Warsh became Fed Chair May 22, 2026. 4. [Yahoo/TradingKey] June 2026 dot plot: 9/19 members project ≥1 hike in 2026. 5. [Advisor Perspectives] Some market measures price in two 25bp hikes for 2026, no further moves through 2027. # Cross-market signals - Kalshi related: no direct series found for this path question; adjacent Kalshi long-dated fed-funds-level markets (KXFEDFUNDSYEAR 2034-36) show modest hike-risk pricing (10-30% "above" thresholds) but are not directly comparable. - Polymarket: 47.5% Yes, falling from 72.5% peak — market has been de-risking the "differs" outcome over the past month. - Sportsbook implied: N/A. # Analyst opinions and speculation - Forbes/bingx (2026-07-30): September hike framed as "most likely outcome" per then-current market pricing — now dated and possibly stale given price decline since. - One chief economist (bingx): full-year hold still "base case" but only a 60/40 call — no desk highly confident. - Fool/InvestmentNews (Aug 2026): hawkish repricing narrative persists but with emerging doubts (gold rally on "hike doubts," 2026-08-09). # Directional lean per outcome - **Yes (differs/Other)**: Supported by hawkish June dot plot, 3 hawkish dissents in July, elevated CPI/PCE trend, Warsh's unpredictable no-forward-guidance stance, and one-source claims of 76-82% Sep hike odds. Independence-based modeling (code_execution) suggests naive P(Other)≈69%. - **No (same three times / hold-hold-hold)**: Supported by falling Polymarket price (72.5%→47.5%), easing unemployment, recent doubts about imminent hike (Aug 9 news), and realistic meeting-to-meeting policy persistence (correlation-adjusted models cut P(Other) to ~45-58%, code_execution sensitivity analysis). # Gaps / unknowns - No confirmed Kalshi-native pricing for this exact multi-meeting question. - No verified September/October-specific hike probability from primary sources (CME FedWatch, etc.) — only secondhand press claims. - No historical base-rate data on 3-meeting sequence "sameness" frequency. - Unclear how much of Polymarket's recent -7%/-3.5% decline reflects genuine reassessment vs. thin-volume noise. # Calibration anchors - Polymarket YES (primary anchor): 47.5%, range 38.5–72.5% over 57 days. - Model-based fair value estimates: 45–69% depending on independence vs. correlation assumptions (code_execution), broadly bracketing the current market price.

1. Both forecasters converge to within 3pp of the Polymarket anchor (47%, 50%) with minimal independent reasoning, but the brief itself flags huge model dispersion (45–69%, with the naive independence estimate at 69%) — neither explains why they weight the correlation-adjusted low end so heavily over the independence-based estimate, they just default to the market. 2. Neither forecaster interrogates the thinness/reliability of the anchor itself: the brief notes "$293k volume" and explicit uncertainty about whether the −7%/−3.5% price drop reflects "genuine reassessment vs. thin-volume noise" — this caveat is dropped entirely rather than used to widen uncertainty around the anchor. 3. The brief reports one economist's "60/40" call favoring hold as the full-year base case, implying P(hold-hold-hold) ≈ 60% (No ≈ 60%), yet both forecasters land at No ≈ 50-53%, understating this direct base-rate signal without explanation. 4. Neither forecaster does the compounding math explicitly: since Yes requires only ONE deviation across the two remaining meetings, even a modest per-meeting hold probability (e.g., 80%) implies ~36% Yes, while a 71% hold probability is needed to justify their ~50% Yes — they should show this arithmetic to justify their implied per-meeting hold rate rather than just splitting the anchor. 5. Both forecasts conflate hike and cut risk under "differs," but the evidence (falling unemployment, no H1 cuts, hawkish dissents/dots) almost entirely supports hike risk over cut risk — neither disaggregates the "Other" bucket into hike-driven vs. cut-driven probability, which could sharpen the estimate. 6. No historical base rate for 3-consecutive-meeting "sameness" was used or estimated by either forecaster despite the brief flagging this as a gap; anchoring purely on a single low-volume, trending Polymarket price without any independent reference class check is a missed robustness step.

46% (52% confidence)

Yes: 46% No: 54%

July is locked as a hold, so this reduces to: do both September and October also hold? Working the compounding math explicitly, a ~30% chance of a hike in September and a conditional ~20-25% chance in October (given a September hold, since a pass typically signals the committee's hawkish minority didn't prevail and inflation/labor data are not forcing action) yields P(all three same) ≈ 0.70 × 0.78 ≈ 0.55, i.e., Yes ≈ 45% — squarely between the naive-independence 69% and the low end of the correlation-adjusted range, and consistent with the 47.5% Polymarket anchor. The 'Other' bucket is almost entirely hike-driven (falling unemployment, no H1 cuts, three hike dissents, hawkish June dots), with essentially no cut path despite political pressure, so it lacks a second independent source of deviation risk. I tilt marginally below the anchor toward 'No' given strong meeting-to-meeting policy persistence, the economist 60/40 full-year hold base case, early-August reporting of renewed doubts about a September hike, and the sustained decline in the Yes price from 72.5%; but the anchor is thin-volume and the hawkish setup is genuine, so I stay close rather than moving aggressively.
