Sub-questions (Fermi decomposition)

Has the Fed already changed the federal funds target range in 2026, and if so, in which direction and by how much (per the Fed's openmarket.htm page)?
What is the current federal funds target range and what did the most recent FOMC statement and Summary of Economic Projections (dot plot) signal about the rate path for the rest of 2026?
What probability do fed funds futures / CME FedWatch currently assign to at least one hike by the December 2026 FOMC meeting, and to exactly one hike versus two or more?
What are the latest trends in core PCE, CPI, and unemployment, and are they moving in a direction that would justify a hike (reaccelerating inflation) versus cuts or hold?
Who is the Fed chair following the end of Powell's term in May 2026, and what has the new leadership and FOMC members said publicly about the possibility of hiking?
How many scheduled FOMC meetings remain in 2026 and how do Kalshi's individual meeting-decision markets price a hike at each one?
Historically, how often has the Fed reversed from a cutting/holding cycle to a single hike within a calendar year, and what conditions preceded such reversals?

Planner reasoning

This is a Polymarket question on exactly one 25bp Fed hike occurring in calendar 2026, resolving on FOMC statements and the Fed's openmarket page. Key drivers are whether any hike has already occurred, the current policy stance and guidance from the (possibly new) Fed chair, inflation/labor data, and market-implied hike probabilities from fed funds futures and Kalshi's KXFED markets. I anchor on the Polymarket price, check the resolution source for the current rate path, pull FRED macro data, and use news plus cross-venue markets to triangulate.

# Current state The Fed already delivered a 25bp hike on Sept 16, 2026 (target range now 3.75%–4.00%), its first hike since 2023, under new Chair Kevin Warsh. Because this market appears to resolve on the **exact** hike count for 2026 (per rules: "resolve early to No if...more hikes have already occurred than the strike"), one hike has already occurred, and the key remaining question is whether a **second** hike (making the outcome "2+", not "1") lands before year-end. Dot-plot and futures signals point to a meaningfully likely second hike, which would flip this specific "exactly 1" market to No. # Timeline of key events - 2026-05-22: Kevin Warsh sworn in as Fed Chair, succeeding Powell (confirmed, brookings.edu/cnbc.com). - 2026-07 (FOMC meeting): Fed held rates steady; 3 members dissented in favor of hiking (confirmed, cnbc.com). - 2026-08-07: September hike odds fall to ~45% after weak July jobs report (reported, cnbc.com). - 2026-08-31: CME FedWatch shows 66% odds of Sept hike (reported, forbes.com). - 2026-09-10: CPI/PPI data push Sept hike odds to ~70–71%; Dec hike odds to ~60% (reported, cnbc.com). - 2026-09-16: FOMC hikes 25bp to 3.75%–4.00% in 12-0 vote; SEP dot plot shows 16/18 members expect another 2026 hike (4 expect two more); Warsh cites inflation "too high for too long" (confirmed, federalreserve.gov, cnbc.com, schwab.com). - 2026-09-16 to 2026-09-20: Post-meeting futures put Oct hike odds at ~49–60%, and odds of "at least one more hike this year" at ~87% (reported, schwab.com, growbeansprout.com). # Event Will exactly 1 (25bp-equivalent) Fed rate hike occur in calendar year 2026, per FOMC statements/openmarket.htm. # Outcomes to forecast Yes / No # Kalshi market anchor No kalshi_direct data was returned (tool not run/available). Best direct proxy is **Polymarket price on this identical market: 13.5% YES**, down sharply from a 90-day high of 57.5% (7d: -34%, 30d: -25%), on $143.5K volume — a large repricing consistent with the market shifting from "will any hike happen" uncertainty (pre-Sept) to "will exactly one (not two) happen" (post-Sept, second-hike risk now dominant). # Resolution source Fed's openmarket.htm and fomccalendars.htm pages were fetched but only returned navigation menus — no substantive rate-action text was captured. However, FRED data and news corroborate a hike occurred: DFEDTARU/DFEDTARL rose from 3.50-3.75% to 3.75-4.00% around 2026-09-17, confirming one 25bp hike already executed in 2026. # Sub-question answers 1. **Already hiked in 2026?** Yes — 25bp hike to 3.75%–4.00% on 2026-09-16, confirmed by Fed press release and FRED target-rate series (DFEDTARU/DFEDTARL step up 9/16-9/17). 2. **Current range & SEP signal?** 3.75%–4.00%. Sept SEP: 16/18 participants project ≥1 more hike in 2026 (4 project two more), 2 project none; no hikes penciled in for 2027+; cuts expected 2028-2029 (cnbc.com/schwab.com). 3. **Futures-implied odds?** CME FedWatch showed ~49–60% for an Oct 28 hike and ~87% odds of "at least one more hike this year" shortly after the Sept meeting (schwab.com, growbeansprout.com). No explicit "exactly 1 vs 2+" split reported, but Polymarket's separate "Another Fed rate hike in 2026?" market prices 85.5% Yes, implying a second hike is the modal outcome. 4. **Inflation/labor trend?** Core PCE rising steadily (index 126.95→130.66, Sep25–Jul26), YoY headline PCE 3.7%, core 3.4% per Sept SEP — both reaccelerating and well above 2% target. CPI index also climbing (324.2→334.1). Unemployment easing modestly (4.4%→4.1%), labor resilient — combination supports further hikes (claude_news, FRED). 5. **New Fed leadership?** Kevin Warsh, sworn in 2026-05-22, is notably hawkish; called inflation "too high...for too long" and led the Sept hike unanimously (12-0) (cnbc.com, brookings.edu). 6. **Remaining meetings & Kalshi pricing?** Two meetings likely remain (Oct 28, Dec 2026) per description. Kalshi meeting-specific series (KXFEDDECISION) returned no signal. Polymarket's Oct 2026 meeting markets: +25bp hike 54.5% Yes, no change 44.5%, +50bp 0.85%, cuts <1% — hike is favored for Oct. 7. **Historical base rate?** Exactly one 25bp hike in a calendar year (no other hikes) occurred in 3/35 years (1990-2024) ≈8.6%; broadening to any single hike of any size, 5/35 ≈14.3%. Hikes historically cluster into multi-hike cycles rather than isolated single hikes (code_execution analysis). # Key facts 1. [federalreserve.gov] Fed hiked 25bp to 3.75-4.00% on 2026-09-16, 12-0 vote. 2. [FRED] DFEDTARU/DFEDTARL confirm the step-up around 9/16-9/17/2026. 3. [cnbc.com/schwab.com] SEP dot plot: 16/18 see ≥1 more hike in 2026; 4 see two more. 4. [growbeansprout.com] CME FedWatch: ~59.7% probability of a hike at the Oct 28 meeting (as of 9/20/2026). 5. [FRED] Core PCE and CPI both trending up through mid-2026; unemployment near 4.1-4.4%. # Cross-market signals - Kalshi related: "Next Fed rate hike — Before 2027" at 85% (confirms hike-has-happened/likely narrative, not specific to "exactly 1"). - Polymarket: This market (exactly 1 hike) at 13.5% Yes; "Another Fed rate hike in 2026?" (implying 2nd hike) at 85.5% Yes; Oct-meeting +25bp market at 54.5% Yes; "No Fed rate cuts in 2026" at 95.65% Yes (consistent with tightening bias, not cutting). - Sportsbook implied: N/A. # Analyst opinions and speculation - Barclays predicted two 2026 hikes (Sept + Dec) — matches dot-plot majority view (claude_news). - Yardeni: second-hike timing/dot-plot critical for 10Y yield direction; flags hawkish risk (cnbc.com). - LPL's Roach: Iran conflict-driven oil/inflation pressure entrenching, favors more hikes (cnbc.com). # Directional lean per outcome - **Yes (exactly 1 hike)**: Supported by base-rate rarity of exactly-2-hike years being uncommon, and possibility Oct/Dec holds occur if labor weakens further. Opposed by: SEP majority (16/18) expecting more hikes, ~60-87% futures odds of a second hike, hawkish new chair, reaccelerating inflation. - **No (0 or 2+ hikes, i.e., not exactly 1)**: Strongly favored — either a second hike materializes (dot plot/futures majority view) or, less likely, hikes pause after one. Market pricing (Polymarket 13.5% Yes) and "Another hike" market (85.5% Yes) both point to No as favorite. # Gaps / unknowns - No live Kalshi-direct price for this specific ticker was retrieved; Polymarket used as best proxy. - Exact FedWatch split between "exactly 1" vs "2+" not directly reported. - Kalshi meeting-level (KXFEDDECISION) series returned no data for Oct/Dec decisions. - Whether Oct or Dec hike (if any) already occurred is unconfirmed beyond Sept — data cuts off ~2026-09-20. # Calibration anchors - Polymarket price for this exact market: 13.5% YES (down from 57.5% high). - Historical base rate for exactly-one-hike years: ~8.6-14.3% (1990-2024). - Current market-implied odds of a second 2026 hike: ~60-87%, making "exactly 1" the less likely bucket.

One 25bp hike already occurred on Sept 16, 2026 (3.75–4.00%, 12-0 vote, confirmed via Fed release and FRED), so this 'exactly 1' market now hinges on whether a second hike lands at the Oct 28 or Dec meeting. The Sept SEP shows 16/18 participants expecting at least one more 2026 hike, CME FedWatch put ~87% odds on another hike this year (~55-60% for Oct alone), and Polymarket prices 'another hike in 2026' at 85.5% while this identical exactly-1 market sits at 13.5% YES. With a hawkish new Chair Warsh, core PCE at 3.4% and reaccelerating, and a low historical base rate (~9-14%) for isolated single-hike years, the second-hike scenario is the modal outcome. I set YES slightly above the Polymarket anchor to account for two remaining meetings, data-dependency, and the possibility labor softening prompts a pause.

One 25bp hike already occurred on Sept 16, 2026 (3.75–4.00%), so 'exactly 1' now requires holds at both the Oct 28 and December meetings. The Sept SEP shows 16/18 participants expecting at least one more 2026 hike, CME FedWatch put a second hike at ~60% for October and ~87% for 'at least one more this year,' and Polymarket's 'Another Fed rate hike in 2026' market sits at 85.5% Yes. The identical Polymarket contract prices exactly-one at 13.5%, and the historical base rate for isolated single-hike years (~9–14%) reinforces that hikes cluster. I shade slightly above the market to account for a possible labor-market deterioration under a hawkish but data-dependent Warsh Fed that could stall the second hike.

One 25bp hike already occurred on Sept 16, 2026 (confirmed by Fed release and FRED), so this 'exactly 1' market resolves Yes only if no second hike lands at the Oct or Dec meetings. The Sept SEP shows 16/18 participants projecting at least one more 2026 hike, CME FedWatch put a second hike this year at ~87% (Oct hike ~50-60%), a hawkish new Chair Warsh led a unanimous hike citing inflation 'too high for too long,' and core PCE is reaccelerating (3.4%). Polymarket prices this identical market at 13.5% Yes and 'another hike in 2026' at 85.5%, consistent with the historical pattern that hikes cluster into multi-hike cycles. I anchor near the market with a small upward shade for the possibility that weak labor data or oil-shock unwind produces two consecutive holds.

Yes	14%
No	86%

The confirmed September 16 hike means Yes now requires the Fed to hold at both remaining 2026 meetings. That is unlikely because 16 of 18 SEP participants project at least one additional hike, inflation remains above target, and post-meeting futures implied roughly an 87% chance of another hike. Hawkish Chair Kevin Warsh, the unanimous September decision, and the historical tendency for hikes to cluster reinforce the No case. I remain close to the best available market anchor, Polymarket's 13.5% YES price, nudging Yes to 14% to reflect uncertainty in the reported futures estimates and two remaining meetings.

Yes	14%
No	86%

The confirmed September 25bp hike means Yes now requires no additional hike at either remaining 2026 meeting. The 13.5% Polymarket YES price is the best available consensus anchor, while 16 of 18 SEP participants projecting another hike and roughly 85.5% cross-market odds of another hike strongly favor No. Reaccelerating inflation, resilient employment, and Chair Warsh's hawkish posture reinforce the likelihood of a second hike, although weakening data could still produce two holds. I place Yes slightly above the 13.5% anchor to account for policy and resolution-source uncertainty.
