Market Clarification
Definition
A market clarification is a statement issued after trading has started that explains how a market's rules apply to circumstances they did not foresee. It is meant to resolve uncertainty, not to change the question. Polymarket calls these 'Additional context' updates and says they 'cannot change the fundamental intent of the question' and 'should be considered by UMA voters when resolving disputes.'
Why it matters
A clarification can move a market's price sharply, and a trader holding a position cannot stop it. Investors should watch for clarification notices on markets they hold, re-check the rules when one is issued, and remember that resting orders may be cancelled and need replacing.
Common misconceptions
- •A clarification is not a new market; positions carry over.
- •Clarifications cannot change a question's fundamental intent, but they can decide close calls.
- •Cancelled resting orders do not refill themselves.
- •The label is only a starting point. Investor outcomes usually depend on the governing documents, cash-flow priority, valuation policy, disclosure quality, and manager discretion surrounding the term, not just the shorthand definition used in marketing materials.

How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- Can a platform clarify a market after trading starts?
- Yes. Polymarket says 'in rare cases, unforeseen circumstances require clarification of the rules after trading begins,' and publishes clarifications 'onchain via the bulletin board contract.' Traders can request one in Polymarket's Discord #market-review channel.
- What happens to my orders when a market is clarified?
- On Polymarket they are cancelled. 'When a market is clarified, the order book is cleared and all resting orders cancelled at the time of clarification. If a clarification is announced in advance, the order book is also cleared at the time of the announcement.' Positions stay; resting orders must be re-entered.
- Why clear the order book?
- Because resting orders were priced under the old understanding. Clearing them prevents traders who saw the clarification first from filling stale orders at prices that no longer reflect the market.
