The European Central Bank met on September 9 and 10. The contract on that meeting was still priced at 99 cents and marked unresolved on September 16.
A Robinhood prediction market contract on the European Central Bank's September rate decision, carrying an event date of September 10, 2026, was still displaying as "LIVE" on Wednesday, September 16, with the 25 basis point hike outcome priced at 99 cents.
The ECB's September decision occurred on September 9 and 10, as corroborated by multiple sources. The contract's event date has passed. The contract had not, as of Wednesday, shown any sign of settlement.
This is not a one-off observation. The same pattern has been documented across multiple checks going back several weeks, and Wednesday's reading is an independent re-confirmation rather than a repetition of an earlier finding.
Why a settlement display issue is worth attention
The natural reaction is that this is cosmetic. A price of 99 cents on an outcome that has already occurred is, economically, nearly the same as a settled position paying out at a dollar. The holder is not obviously worse off.
That reaction understates the issue for three reasons.
First, capital efficiency. An unsettled position ties up collateral that a settled position would release. A participant holding a contract that resolved six days ago cannot redeploy those funds, which has a real, if small, cost that compounds across positions and across time. That cost is rising: the Federal Reserve raised its policy rate to 3.75% to 4.00% on Wednesday, so idle collateral is now forgoing more.
Second, price integrity. A contract still displaying as live on a determined outcome remains, in principle, tradeable. Anyone transacting at 99 cents on a question whose answer is already public is not taking a position on an uncertain event. They are transacting on stale display.
Third, and most importantly, this is a control question rather than a pricing question. Settlement is the operational core of any event contract venue. If a contract on a scheduled decision by one of the world's two most important central banks, arguably the easiest event on the calendar to resolve, is still open six days later, the relevant question is what process is supposed to close it and why that process did not run.
The timing sharpens the point. Wednesday brought a far more heavily traded central bank event in the Federal Reserve's own decision, and how quickly contracts on that outcome settle is now an immediate, observable test of the same process.
The scope of what is claimed
This describes the display and settlement state of one contract page on one platform at a specific time. It is not a claim about the ECB's actual September policy decision, which is separately established. It is not a claim about the platform's handling of any other contract, and it is not evidence of any loss to any participant.
What would resolve it
A settlement of the contract, or an explanation from the platform of whether the display reflects an actual unsettled position or a front-end rendering issue on a contract that has in fact been resolved behind it. Those are materially different situations, and from the outside they look identical.
