What backend challenges did you face while building a prediction marketplace?

From what I've noticed, one of the biggest challenges when building a prediction marketplace is handling real-time data updates. As users place predictions and market conditions change, the platform must process and display updated information instantly without affecting performance.

Another challenge is ensuring accurate market settlement, as it requires a reliable way to verify outcomes, calculate results, and distribute rewards fairly. Even a small error in this process can affect user trust and platform credibility.

Scalability is also important. As the number of users and active markets grows, the platform must be able to handle increased traffic and data efficiently.
There may be other challenges, but these are some of the most important ones to focus on. If you're developing a prediction marketplace, make sure to address these areas carefully from the beginning.
