How does Polymarket work?

A standard binary market uses Yes and No outcomes. The documentation describes positions as outcome tokens; their settlement depends on the resolution conditions. That is more specific than agreeing with a news narrative. Being broadly right about a story does not establish that the exact condition of a contract has been met.

Orders meet other participants’ offers in an order book. An expression of interest can remain unfilled or fill only in part. A displayed estimate therefore does not promise that any quantity can be bought at that price. When reading the signal, identify its source and basis instead of assuming an available completed transaction.

Take a hypothetical standard binary contract and 10 Yes shares filled at 0.40 pUSD each. Acquisition costs 10 × 0.40 = 4 pUSD before expenses. If the holder retains all 10 and the confirmed Yes result pays 1 pUSD per share, redemption returns 10 pUSD. The difference from acquisition cost is 6 pUSD before expenses, rather than the entire 10 received.

With a standard No result, these Yes shares pay zero and the acquisition loss is 4 pUSD before expenses. If all 10 are sold before resolution at an illustrative 0.50, proceeds are 5 and the difference is 1 before expenses; later redemption no longer belongs to the sold shares. A sale needs a buyer and an eligible operation. These are three teaching scenarios, not available offers. Split settlement, partial fills and expenses change the result.

A deadline does not guarantee immediate confirmation. The result can still require clarification or a dispute process. OddsAtlas separates market status from data freshness: a closed contract can still have an old snapshot. Look for a confirmed outcome and its source rather than treating the absence of an active quote as the final answer.

A button label or order status does not determine the event result either; result verification belongs to the contract itself.
