Integrity Issue: Exploitation of Resolved Markets & Proposed Fixes

I am writing to bring to your attention a serious loophole currently being exploited in the prediction market competition, which directly undermines its integrity and fairness as a student initiative.

Recently, I observed two specific markets that were approved (voted through) and went live after the real-world outcomes were already known:

• "2026 IIHF Ice Hockey winner?" – Where the creator intentionally set the deadline days after the event had already concluded.

• "Shakira, Burna Boy - Dai Dai (Official Video) over 10 Million views by end of May?"

Because the outcomes were already public knowledge before the markets were even online, these markets became "easy money" for the users who provided the final upvotes to launch them, as well as the traders who rushed in first to grab the guaranteed odds. This completely violates the spirit of a prediction market.

To restore a level playing field and prevent future exploitation, I highly recommend implementing the following measures:

• Void Unfair Winnings: It would only be fair to void the trades and claw back the winnings from individuals who traded on these already-resolved markets.

• Penalize Market Creators: Penalize or block users who intentionally set market deadlines to occur days after the actual event takes place.

• Implement a Strike System for Upvotes: Introduce a strike system for users who upvote a market that has an already-known outcome. If a user repeatedly abuses this to push dead markets live for profit, they should face a temporary or permanent block.

• Introduce a Trading Cool-Down Period: Implement a feature where trading only opens after a set amount of time (e.g., one hour) after the final approval upvote is cast. This ensures that users who happen to cast the final vote or sit on the platform all day don't get an unfair structural advantage over those who cannot monitor the app constantly.

If this competition is to remain fair, these loopholes need to be closed. Thank you for your time, hard work, and dedication to keeping this competition competitive and just.
