What moves the probability
Three meetings, 25 basis points each
With only the 15-16 September, 27-28 October and 8-9 December meetings left, the number of levels the target range can reach by year-end is bounded. Every 25 basis point rung outside that band is effectively excluded, which is what pins tail contracts at zero. This is the largest single factor and it tightens with each meeting that passes.
The September and December projections
The Summary of Economic Projections released on 16 September and again in December states each participant's view of the appropriate year-end rate. A cluster in the projections that sits at or moves toward 2.75-3.00% would push this contract up; a cluster elsewhere confirms the current price. It is the most direct public evidence available on the Committee's own expected landing point.
Labour market and inflation data
Monthly employment reports and CPI releases between now and December are the inputs that could justify a larger-than-standard move. A sharp deterioration in payrolls is the main route to a 50 basis point step, which is what would be needed to reach a level currently outside the band. Steady data leaves the expected path intact and keeps tail levels at the floor.
Level-specific settlement risk
Being right about direction is not enough โ the upper bound has to read exactly 3.00%. Probability leaks to the neighbouring rungs on either side, which is why these contracts trade far below what a directional view alone would imply. This structural feature pushes the price down regardless of the macro picture.
Intermeeting action
The Committee can move outside the scheduled calendar in a crisis, as it has done in past shocks. That is the only mechanism by which a level several steps away becomes reachable in three months. It is a low-probability channel, but it is the one that stops these contracts from trading at absolute zero.
Single-venue pricing
Because only Polymarket lists this question, there is no second book against which to check the price. That removes the cross-venue spread that usually flags a rules difference or a genuine disagreement. It also means liquidity and the price both depend on one order book.
The case for
- The 16 September and December Summary of Economic Projections would need to show participants converging on a year-end range of 2.75-3.00%, and the statement language would have to point in the same direction.
- A materially weaker labour market โ evident in the employment reports released before the 27-28 October meeting โ could justify a 50 basis point move that brings otherwise unreachable levels within range.
- Because the settlement question is a single number in a single published statement, a path that gets the Committee to 2.75-3.00% by 9 December resolves this Yes with no interpretive dispute.
- An intermeeting decision, of the kind taken in previous shocks, would collapse the arithmetic constraint that currently keeps this contract at the floor.
The case against
- Only three scheduled meetings remain, and the Committee's standing practice of 25 basis point steps caps how far the target range can travel by 9 December.
- The contract requires the upper bound to read exactly 3.00%; a path that is directionally correct but lands one rung away settles at nothing.
- Cumulative volume near $498,284 with the price at the bottom of its range indicates a considered market verdict rather than an unpriced listing.
- Level ladders like this one concentrate almost all their value in one or two rungs, and contracts in the tails historically stay there until settlement.
