Sub-questions (Fermi decomposition)

What probability does the Polymarket market currently assign to a hike, and how has it trended over the last 90 days?
What do Kalshi and Polymarket FOMC-meeting markets (Oct 2026 and Dec 2026) imply for the probability of a hike vs. hold vs. cut at each meeting?
What is the current fed funds target range and has the Fed hiked or cut at any 2026 meeting so far, per the Fed's openmarket.htm page?
Are core PCE/CPI inflation and inflation expectations (T10YIE, breakevens) re-accelerating in a way that would push the FOMC toward tightening, or are they trending toward 2%?
Is the labor market (unemployment rate, payrolls) weakening (arguing for cuts/hold) or tight (raising hike risk)?
What have Fed officials (Chair, governors, regional presidents) and the latest FOMC statement/dot plot said about the possibility of rate hikes in late 2026?
Historically, how often has the Fed hiked within ~3 months of a hold/cutting cycle without prior signaling, i.e., what is the base rate for an unsignaled pivot to hikes?

Planner reasoning

This is a Polymarket question about whether the Fed raises the upper bound of the fed funds target between Sept 17 and Dec 9, 2026 — a period in which the Fed is widely expected to be in a hold/cutting cycle, so a hike is a low-probability tail event driven mainly by an inflation resurgence. The key drivers are the current market price, the futures-implied path (Kalshi/Polymarket FOMC decision markets), recent inflation/labor data, and Fed communication about the balance of risks. The Fed's openmarket.htm page is the named resolution source and should be checked directly.

# Current state The Fed hiked 25bp on 2026-09-16 (to 3.75–4.00%), its first hike since 2023 — but per the resolution rules, this September hike does NOT count toward this market. Resolution requires a further hike between Sept 17, 2026 and the Dec 8-9, 2026 meeting (Oct 27-28 and Dec meetings are in scope). The Fed's own dot plot and FedWatch-implied odds strongly favor at least one more hike before year-end. # Timeline of key events - 2026-08-28 (confirmed): Chair Warsh, at Jackson Hole, flags underlying inflation hasn't "meaningfully improved," seen as opening door to a hike (CNBC, Fortune). - 2026-09-03 (reported): Gov. Waller pushes back, citing two months of improving inflation data, urging patience (Axios). - 2026-09-11 (reported): Hot August CPI (core +0.3% m/m) raises September-hike odds >90% in futures (Bloomberg/TheStreet). - 2026-09-16 (confirmed): FOMC hikes 25bp to 3.75–4.00%, 12-0 vote; dot plot shows 16/18 officials expect ≥1 more hike in 2026; three members (Hammack, Kashkari, Logan) had dissented hawkishly in July (federalreserve.gov, CNBC). - 2026-09-17+ (reported): CME FedWatch prices Oct hike near 50/50, cumulative Dec hike probability ~88.5% (TheStreet). - 2026-10-27/28 (scheduled, pending): Next FOMC meeting — decision counts toward this market. - 2026-12-08/09 (scheduled, pending): Final meeting in scope for resolution. # Event Will the Fed's target federal funds rate upper bound be hiked at any point between 2026-09-17 and the conclusion of the Dec 2026 FOMC meeting? # Outcomes to forecast Yes / No # Kalshi market anchor No kalshi_direct price was returned for this specific ticker. Closest Kalshi proxy: "Next Fed rate hike? — Before 2027" (KXFEDHIKE-2-26DEC31) at 86% YES, +4% over 7d/30d, avg daily volume ~4,516 contracts — a near-identical scope market trading close to Polymarket's level. Treat 86-89% as the effective consensus band. # Resolution source federalreserve.gov/monetarypolicy/openmarket.htm fetched but returned only generic navigation content — no decision data. However, claude_news independently sourced the actual Sept 16, 2026 FOMC press release (federalreserve.gov/newsevents/pressreleases/monetary20260916a.htm) confirming the 25bp hike to 3.75-4.00%. That September hike is explicitly excluded from this market's resolution; the page does not yet reflect any post-Sept-17 decision since Oct/Dec meetings haven't occurred. # Sub-question answers 1. **Polymarket trend** — Currently 88.5% YES, up from 79.5% 30 days ago (+9pts in both 7d and 30d windows); low volume (~$67k) but consistent uptrend post-September hike. 2. **Oct/Dec meeting-level odds** — Polymarket Oct 2026 meeting markets: +25bp hike 54.5%, no change 43.5%, +50bp 0.85% (implies ~55% hike probability in October alone). CME FedWatch (via TheStreet) has Oct near 50/50 and cumulative Dec hike odds ~88.5%. 3. **Current target range / 2026 hikes so far** — 3.75%–4.00% as of Sept 16, 2026 (up from 3.50-3.75%); this was the first 2026 hike, per Fed press release and CNBC. FRED DFEDTARU confirms upper bound moved from 3.75 to 4.0 around 9/17. 4. **Inflation trajectory** — Not converging to 2%: core PCE ~3.7% y/y and 4.1% 6-month annualized as of Jackson Hole (Aug); core CPI +0.3% m/m in August; T10YIE (10y breakeven) ~2.33-2.4%, modestly elevated but not runaway. FRED CPILFESL/PCEPILFE show steady monthly increases through mid-2026, no clear disinflation. 5. **Labor market** — Described by Fed statement as solid: "job gains have kept pace with the workforce, unemployment rate has changed little" — tight/stable, not weakening, supporting further tightening bias. 6. **Fed officials/dot plot** — Chair Warsh explicitly hawkish ("inflation too high, too long"); dot plot shows 16/18 members expect ≥1 more 2026 hike; 2026 year-end median dot raised to 4.1-4.4% (from 3.6-4.1%), implying ~1-2 more hikes priced by the Fed itself. Dissent exists (Waller dovish-leaning) but is a minority. 7. **Historical base rate** — Unsignaled pivots to hiking after a hold/cut regime are extremely rare (~0.3-2% per 3-month window historically). However, this is NOT an unsignaled scenario — the Fed already hiked in September and telegraphed more via the dot plot, making historical "surprise pivot" base rates largely inapplicable here. # Key facts (high-confidence, factual) 1. [federalreserve.gov/CNBC] Sept 16, 2026: Fed hiked 25bp to 3.75-4.00%, 12-0 vote (excluded from this market). 2. [Advisor Perspectives] Dot plot: 16/18 officials expect ≥1 more hike in 2026; year-end 2026 median dot raised to 4.1-4.4%. 3. [TheStreet/CME FedWatch] Oct 2026 hike ~50/50; cumulative Dec 2026 hike probability ~88.5%. 4. [FRED] Core PCE/CPI still rising steadily monthly through Aug 2026; T10YIE ~2.33%. 5. [Polymarket] "Another Fed rate hike in 2026?" at 88.5-89%, up from 79.5% a month ago. # Cross-market signals - Kalshi related: "Next Fed hike before 2027" 86% YES (+4% 7d/30d). - Polymarket direct (this market): 88.5-89% YES. - Polymarket Oct meeting breakdown: +25bp 54.5%, no change 43.5%. - Polymarket "no Fed rate cuts in 2026" at 95.65% — reinforces no-cut/hike-leaning consensus. # Analyst opinions and speculation - Oxford Economics (Pearce): pushes back, says market has "too much tightening priced in," doesn't see a major new cycle. - Johnson Investment Counsel (Zureick): sees "another hike or two" if energy prices/economy stay elevated. - CNBC commentary: "unlikely to be the end of Fed rate hikes." - Political: Trump pressuring for cuts; Fed publicly asserts independence — a wildcard against further hikes but no sign of yielding yet. # Directional lean per outcome - **Yes**: Strong — active hiking cycle already restarted in Sept, dot plot majority favors more hikes, inflation still elevated (~3.7% PCE), labor market resilient, market pricing (Poly/Kalshi) both ~86-89%. - **No**: Weaker — requires inflation to cool faster than expected, dovish dissenters (Waller) gaining ground, or political pressure forcing a pause; Oct hike priced only slightly above coin-flip, leaving room for a hold-then-no-further-hike scenario. # Gaps / unknowns - No live kalshi_direct price for this exact ticker was retrieved. - Oct 27-28 and Dec 8-9 meeting outcomes are still pending; no confirmed data beyond Sept 20, 2026. - Political pressure from Trump on Fed independence could shift the reaction function unpredictably. # Calibration anchors - Consensus estimate: ~86-89% (Polymarket 88.5%, Kalshi proxy 86%). - Historical base rate for unsignaled pivot to hike: <2% (not directly applicable — this is a signaled, active tightening cycle, not a pivot).

The Fed restarted its hiking cycle on Sept 16 (12-0 vote) and the dot plot shows 16/18 officials expecting at least one more 2026 hike, with the year-end median dot implying 1-2 additional moves; core PCE (~3.7% y/y) and a solid labor market give little reason to pause. Market pricing is tightly clustered: Kalshi's near-identical 'Next Fed hike before 2027' proxy at 86%, Polymarket at 88.5%, and CME FedWatch cumulative December odds ~88.5%, with October alone near 55%. Two meetings remain in scope, so even an October hold leaves a December opportunity. I shade slightly below consensus (0.85) to account for the well-documented tendency of dot plots and futures to overstate follow-through, Waller-style dovish pushback if inflation data soften, and political pressure — but no specific unpriced information justifies a larger move away from the anchor.

The Fed restarted a hiking cycle on Sept 16, 2026 (12-0 vote) and its dot plot shows 16/18 officials expecting at least one more 2026 hike, with the year-end median dot raised to 4.1-4.4%, implying 1-2 additional hikes across the two in-scope meetings (Oct 27-28, Dec 8-9). Core PCE remains ~3.7% y/y with no clear disinflation, the labor market is described as solid, and Chair Warsh is explicitly hawkish, so the causal case for another hike is strong. Market consensus is tight: Polymarket 88.5% YES and the near-identical Kalshi proxy 'Next Fed hike before 2027' at 86%, with CME FedWatch cumulative Dec odds ~88.5%. I shade slightly below consensus to account for two-meeting dependency risk—Oct is only ~50/50, dovish dissent (Waller), political pressure from Trump, and the historical tendency of markets/dots to overshoot realized hikes—landing at 0.85 YES.

The Fed restarted a hiking cycle on Sept 16 with a unanimous 25bp move, and the dot plot shows 16 of 18 officials expecting at least one more 2026 hike, with the year-end median raised to 4.1–4.4%. Core PCE remains ~3.7% y/y with no clear disinflation, the labor market is described as solid, and Chair Warsh is explicitly hawkish, giving two in-scope meetings (Oct, Dec) to deliver. Market consensus is tight: Kalshi proxy 'Next Fed hike before 2027' at 86%, Polymarket direct at 88.5%, and CME FedWatch cumulative Dec odds ~88.5%. I anchor near the consensus band at 0.86, discounting slightly for dot-plot overstatement risk, Waller-style dovish pushback if inflation cools, and political pressure from the White House.

The effective Kalshi consensus is 86% YES, while the direct Polymarket and CME-implied cumulative odds are approximately 88.5%, anchoring the forecast near 88%. The Fed has already restarted tightening, and 16 of 18 officials project at least one additional 2026 hike, making this a signaled continuation rather than a historically rare surprise pivot. Persistent core inflation, a stable labor market, and an October hike probability near 55% further support YES, although upcoming inflation data, dovish opposition, and political pressure leave a meaningful pause risk.

The effective Kalshi consensus is 86% YES, while the direct Polymarket and CME cumulative pricing are approximately 88.5%, anchoring the forecast near 88%. Meeting-level pricing implies only about a 55% October hike chance, but the additional December opportunity substantially raises the cumulative probability. The 16-of-18 dot-plot majority expecting another 2026 hike, persistently elevated core inflation, and a solid labor market all point toward Yes. I remain close to rather than above consensus because incoming inflation data, Waller's preference for patience, and political pressure could still produce holds at both meetings.
