When a rate decision lands, settlement questions follow fast: what did the Federal Reserve actually announce, and how did the related Kalshi event finalize? For the September 2026 meeting, both answers are on the record. This event update on the September 2026 FOMC decision and Kalshi settlement sources keeps those two facts separate and names the source behind each.
Primary sources checked: the Kalshi event API record for KXFEDDECISION-26SEP (snapshot pulled 2026-09-17T05:31:36Z), the Federal Reserve statement of September 16, 2026, and the CFTC designation record for KalshiEX. Each fact below traces to one of these records or to a Federal Reserve page linked in the body.
Per the official FOMC calendar, the Committee met September 15-16, 2026. The statement was released at 2:00 p.m. EDT on September 16 and approved by a 12-0 vote. The Committee raised the target range for the federal funds rate by 1/4 percentage point, to 3-3/4 to 4 percent. The prior range of 3-1/2 to 3-3/4 percent had been maintained at the July 2026 meeting, so September was a hike, not a hold.
The Committee said it is continuing its policy of maintaining ample reserves, and a Summary of Economic Projections was released with the meeting. The statement's assessment, in brief:
The Kalshi result is a separately sourced fact. The event, titled "Fed decision in Sep 2026?", carried five mutually exclusive markets. In the API snapshot checked at 2026-09-17T05:31:36Z, all five reported status finalized, each with close_time 2026-09-16T17:59:00Z:
A second retrieval at 2026-09-17T05:49:01Z matched on tickers, statuses, results, and close times; the first snapshot's canonical JSON SHA-256 is d934fe039fac05bbeeb0432175ebe274c0ac4639003eba6263b09a3660165a24. Two cautions come from the record itself. The snapshot carries no settlement_source field, so this page claims none. And this is a dated snapshot, not a live feed; for any later correction or dispute, the operative text sits in the market rules on kalshi.com.
The winning market's primary rule, verbatim: "If the Federal Reserve does a Hike of 25bps on September 16, 2026, then the market resolves to Yes." Shared secondary rules state that the five outcomes are mutually exclusive, that at most one bucket resolves yes, and, per a note dated 4/28/25, that a canceled meeting which does not occur on its scheduled date sends "Fed maintains rate" to yes and all other buckets to no.
Two reading points matter. First, the decision date written into the rule, September 16, 2026, matched the actual statement date, which is the fact pattern that made H25 the winning bucket. Second, the 17:59:00Z close time applies to this event only; traders should not treat it as a universal cutoff for future FEDDECISION events.
The implementation note effective September 17, 2026 lists the operating rates:
Several administered rates sit near 4 percent in that list, and only one line is the policy target range. The 3.90 percent reserve-balance rate is not the target range, and the 4.0 percent repo and primary credit rates should not be equated with the range's upper bound beyond what the note itself states. Keeping these straight matters when checking whether a market's wording tracked the statement or the note.
The calendar lists the next meeting as October 27-28, 2026, covered in this site's October 2026 FOMC meeting notes. For the pre-event process, the September decision-week checklist and the September meeting market notes show how the rules were read before the result landed. Same-day event updates also go out through the @Kalshi_market channel on Telegram.
Standing habits: Kalshi is a CFTC-regulated, USD-settled exchange with identity verification requirements, and current rules, availability, and any post-finalization corrections come from Kalshi directly. The September 2026 FOMC decision and Kalshi settlement sources cited here are fixed to the 2026-09-17T05:31:36Z snapshot, so treat Kalshi's own pages as the controlling record for anything after that timestamp.
The FOMC raised the target range for the federal funds rate by 25 basis points, to 3-3/4 to 4 percent, from 3-1/2 to 3-3/4 percent. The statement was released at 2:00 p.m. EDT on September 16, 2026, and approved by a 12-0 vote. The Committee said it continues to maintain ample reserves, and a Summary of Economic Projections accompanied the decision.
An API snapshot checked at 2026-09-17T05:31:36Z showed all five markets in the KXFEDDECISION-26SEP event reporting status finalized. KXFEDDECISION-26SEP-H25, the Hike 25bps market, reported result yes. The maintain, cut 25bps, cut over 25bps, and hike over 25bps markets each reported result no. All five carried a close time of 2026-09-16T17:59:00Z, and any later correction would come from Kalshi directly.
The implementation note effective September 17, 2026 sets the interest rate paid on reserve balances at 3.90 percent, approved by a unanimous Board vote. That administered rate is distinct from the 3-3/4 to 4 percent federal funds target range. The same note lists a 4.0 percent standing repo rate, a 3.75 percent reverse repo offering rate, and a 4.0 percent primary credit rate.
The official FOMC calendar lists the next meeting as October 27-28, 2026. Future Fed decision events carry their own tickers, rule text, and close times, so the September event's 17:59:00Z close should not be assumed to apply. This site's October 2026 FOMC coverage collects the sources worth checking before that meeting.
