A named next-meeting lead is still not an instruction.
What is settled
The FOMC statement released at 14:00 EDT on September 16 says the Committee raised the target range by 25 bp to 3.75%–4.00% in a 12–0 vote. That official statement is the September result. A market’s later settlement label is not a substitute for it.
What the current October readings mean
At 19:05 UTC on September 22, the direct Kalshi October page displayed 52% for “Hike 25bps” and 48% for “Fed maintains rate.” The direct Polymarket October page displayed 53% for a 25 bp increase and 46% for no change. These are separate event-contract readings accessed at the same time.
What the latest movement does and does not say
Since the 13:38 UTC direct check, Kalshi’s two named rows each rose 1 percentage point. Polymarket’s named hike row rose 3 points to 53%, while no change fell 4 points to 46%. Those are like-for-like observations on each page. They do not reveal who traded, why they traded or what stocks, bonds or a portfolio will do.
Before you call a gap a trade
Run five checks: name the instrument; match the exact outcome; read the settlement rule or calculation; match the observation time; and check whether access, fees, execution and eligibility have actually been assessed. An event contract and a futures-implied calculation can differ on any of these. A different percentage is not itself evidence of arbitrage, and this pool does not assess tradability or give trading advice.
One decision is not a year-end path
These contracts settle on the October FOMC action. A named row does not answer whether the Fed will raise at least once more by year-end, how many later decisions might change, or what a portfolio should do. A year-end claim needs a contract or measure with that exact scope.
Read the rule and the surface
Polymarket’s October rules define the outcome by the upper bound of the target federal funds range and name the October FOMC statement as resolution source. Kalshi’s direct page uses named series headings and hides additional outcomes. Similar labels do not authorize an average, a residual, or a claim that the venues share one probability. Polymarket’s adjacent experimental AI-generated narrative is not used as evidence here.
Keep futures-implied figures separate
CME FedWatch is a 30-Day Fed Funds futures-implied calculation, not an event-contract price. The direct grid was unreadable in this check, so the pool shows no live CME percentage and no spread versus either venue.
What the readings do not mean
- They are not a Federal Reserve forecast or a policy commitment.
- They are not a complete probability distribution made by adding rounded rows.
- They are not an explanation of a separate asset move or a risk-free cross-market trade.
- They are not a personal investment recommendation.
