Clarification Effects

Clarifications have several effects on trading and resolution.

Effect on Orderbook

When Polymarket issues a clarification, the orderbook is cleared and all resting orders are cancelled. If a possible clarification is announced in advance, Polymarket may specify a later time when the orderbook will be cleared.

Example: In Will Venezuela recognize Israel by December 31?, Polymarket announced that a possible clarification would be issued at 3:00 PM ET and that the orderbook would be cleared at that time regardless of whether a clarification was ultimately made.

Effect on Price Action

Clarifications often determine whether a market resolves immediately or remains open. This can cause the price to spike to 100¢ or drop sharply after the clarification.

Example: In Will Trump talk to Luiz Inácio Lula da Silva in October?, Polymarket clarified that talks between the two before the market was created would not count toward resolution. The price fell from 93¢ to 54¢ following the clarification.

Effect on Resolution

Clarifications can directly determine how and whether a market resolves. They often confirm whether an event met the resolution criteria.

Example: In Will Powell say "inflation" 50+ times during September's press conference?, traders counted 49 mentions but disagreed about one timestamp. Polymarket clarified that Powell did say "inflation" during that moment, and the market resolved to Yes.

Anticipation and Market Behavior

Anticipation of a clarification can affect both market volatility and trader behavior.

Volatility

When traders expect a clarification, markets can become volatile. Because a clarification can instantly resolve a market, even small hints or pre-announcements can trigger large price swings.

Example: In Will Ghislaine Maxwell testify before Congress in 2025?, the price ranged between 35¢ and 50¢ as traders anticipated a clarification.

Strategic Manipulation

Some users may try to profit from this volatility. For example, a group of traders may buy shares at 1¢, push for a clarification, and sell at 5¢ if uncertainty drives the price higher.

Others may try to create doubt about the likely outcome to drive down prices and buy winning shares at a discount.

Example: A trader stirring concern among others to drive down prices and buy winning shares at a discount.
