Pre-market and after-hours markets address the gap between conventional stock-market sessions and the continuing flow of stock-related questions. News, earnings, and changing expectations do not stop when the regular equity session ends. ### Extending the prediction-market window The source states the intended operating window as: ``` Sunday 5 PM → Friday 6 PM ``` Crypto markets can operate beyond that window because their underlying market is continuously active. These times are the source’s stated product-design window; this page does not reinterpret them as stock-exchange hours or add unsupported execution rules. ### Why the gap matters An earnings release can arrive after close. News can break outside the regular session. A participant may still want to express a binary view, such as whether a stated stock-token condition will occur. AFTERBELL is designed to keep the prediction-market format available beyond conventional market sessions. Pre-market and after-hours participation does not change the core structure: ``` Defined question → Yes / No order → CLOB trading → defined resolution condition → verification → redemption ``` The CLOB handles signed trading orders. USDG is the settlement asset. ERC-1155 tokens represent Yes and No positions. These components do not remove the need for a precise market definition. ### Open for trading does not mean immediately resolvable A market can be available outside conventional stock hours while its resolution condition remains tied to a specified price or event. The product still needs a defined question, resolution condition, relevant data, verification, and final outcome. For stock-token resolution, AFTERBELL proposes Chainlink as the primary source and the Robinhood REST API as a cross-check. If the two differ by more than 5%, the market pauses and an administrator may resolve using off-chain evidence. The extended trading window does not bypass that verification requirement. ### A stated design objective “24/7” describes the product’s prediction-market positioning, not a guarantee that every underlying stock-market data source is continuously available or that every market can resolve without exception. The source does not specify downtime behavior or additional market-hour mechanics. AFTERBELL is still being developed. Smart contracts are not yet audited, liquidity is not guaranteed, and regulatory clarity remains uncertain. Pre-market and after-hours markets are proposed formats for serving questions that conventional market schedules leave open. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://whitepaper.after-bell.uk/market-design/pre-market-and-after-hours.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
