Fed Decision in September?

Platform comparison

Market context

Polymarket is pricing a September Fed move at just **1% yes**, so the contract is effectively saying the odds of any change in the upper bound of the target federal funds range at the September 2026 FOMC meeting are very low. On Polymarket, traders are buying and selling **USDC**-settled **conditional tokens** on Polygon, so the quoted price reflects the market’s view of the exact basis-point bucket that will resolve after the Fed’s decision, not a generic expectation about the economy.

That low price sits against a recent run of **steady policy**. The Fed has held the target range at **3.50% to 3.75%** in 2026 so far, after earlier cuts in late 2025, and recent market commentary has emphasised a divided Committee and shifting projections around the path of rates.[2][7][9][16] The September meeting is one of the Fed’s scheduled **SEP/dot-plot** meetings, which makes it more informative than a standard hold decision, but the market is still implying that the most likely outcome is no change rather than a 25bp move.[1][3][10]

The main catalysts to watch are the **FOMC calendar** itself, any change in the Fed’s data dependence before 16 September, and how traders interpret the statement, SEP and Chair’s press conference on the day.[1][8] The decision is due at **2:00 pm ET** on 16 September, with the press conference following at **2:30 pm ET**, and Kalshi-style resolution here is mechanical: the upper bound change is measured versus the level before the meeting, with off-grid moves rounded up to the nearest 25bp bucket.[3][8][14] If inflation, labour-market data or the Fed’s own projections shift sharply before then, this market can reprice quickly from a near-flat expectation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
