December 2026 FOMC on Kalshi: Dates & Rules Snapshot

Quick answer: The Federal Reserve calendar lists the December FOMC meeting for December 8-9, 2026, with the policy decision on December 9. Unlike the October meeting, this meeting includes a Summary of Economic Projections and a press conference by the Chair. On August 9, 2026, Kalshi's official event API showed KXFEDDECISION-26DEC with five active, mutually exclusive markets. This is a dated rules snapshot, not a live odds page.

What the Federal Reserve calendar establishes

The official FOMC calendar sets the December 8-9, 2026 meeting. The December meeting carries an asterisk (*), meaning a Summary of Economic Projections is scheduled, followed by a press conference by the Chair. Only the March, June, September, and December 2026 meetings include SEP materials. The calendar was last updated July 29, 2026.

The FOMC typically announces its policy decision at 2:00 PM ET on the second day of a two-day meeting. For December 2026, the decision is expected on December 9 at 2:00 PM ET, followed by the release of the policy statement, the Summary of Economic Projections, and the Chair's press conference.

What the exact Kalshi event snapshot establishes

The August 9 official API response identified event ticker KXFEDDECISION-26DEC, titled "Fed decision in Dec 2026?" The record marked the event mutually exclusive and included five nested markets with status active:

• KXFEDDECISION-26DEC-C26 — Cut >25bps
• KXFEDDECISION-26DEC-C25 — Cut 25bps
• KXFEDDECISION-26DEC-H0 — Hike 0bps (Fed maintains rate)
• KXFEDDECISION-26DEC-H25 — Hike 25bps
• KXFEDDECISION-26DEC-H26 — Hike >25bps

Each nested market reported a close time of 2026-12-09T18:59:00Z (1:59 PM EST) and an expected expiration time of 2026-12-09T19:05:00Z. The settlement source is the Federal Reserve (https://www.federalreserve.gov).

Those are timestamped API facts, not promises that the event or fields will remain unchanged. Reopen the exact event and its live market pages before relying on them.

Two official-source discrepancies to preserve

1. Closing time: The exact event API reported 18:59:00Z, or 1:59 PM EST (UTC−5), while the generic FEDDECISION terms list 1:55 PM ET as the last trading time. The records are not identical, so this page does not select a universal cutoff.
2. One outcome's wording: Ticker KXFEDDECISION-26DEC-C26 has a title that says "Will the Federal Reserve Cut rates by >25bps", while the API's primary-rule text says "Cut of 25bps" and omits the greater-than sign. This page does not silently repair or independently interpret that mismatch.

When a generic document and an exact event record diverge, record the discrepancy and verify the selected market's live rules. Do not turn an editorial guess into settlement language.

Why the December meeting matters more for rate markets

The December 2026 FOMC meeting is the final meeting of the year and one of four that include a Summary of Economic Projections. This means:

• Individual participant projections for real GDP growth, unemployment, PCE inflation, core PCE inflation, and the appropriate federal-funds-rate path.
• A Summary of Economic Projections dot plot released alongside the policy statement.
• A press conference by the Chair of the Federal Reserve.
• The combination of a rate decision and fresh projection materials can move markets more than a non-SEP meeting.

Traders who follow Kalshi Fed decision markets should note that the presence of SEP materials does not change how Kalshi's contracts settle. The settlement source remains the Federal Reserve's policy decision, regardless of the projections. However, the additional information released at an SEP meeting can influence market expectations and trading activity in the periods before and after the announcement.

For context, the September 2026 FOMC meeting and the October 2026 FOMC meeting are the two scheduled meetings preceding December. September includes SEP materials; October does not.

What happens if a scheduled meeting is canceled

According to the Kalshi event's rules, if a scheduled FOMC meeting is canceled and does not occur on its scheduled date, the strike for "Fed maintains rate" resolves to Yes and all others resolve to No. This provision applies to meetings after the May 2025 meeting. This is the event's stated rule, not this article's interpretation.

Live-market verification checklist

1. Event and market identity: Confirm the event ticker, selected market ticker, exact title, status, and mutually exclusive structure.
2. Exact rules: Read the selected market's full rules and named outcome verification source. Do not rely only on the API title.
3. Times: Recheck close time, expiration time, expected determination time, and any last-trading language on the live market page.
4. Wording conflict: If the C26 title and rule text still differ, preserve evidence and seek clarification from Kalshi rather than assuming which symbol was intended.
5. Execution: Inspect the current order book for the full intended size. This article contains no live quote or probability.
6. Fees: Apply the current fee schedule to the intended order rather than copying an old example.
