A few things that could be better
The feed still feels a bit limited in the range of topics. Most of the stories lean toward politics, crypto, and sports. Expanding into more everyday categories would make people stick around longer.
The probabilities are useful, but it’s not always clear how liquid or reliable the underlying market is. Adding a simple indicator of volume or confidence would help.
Also, coming back later to check how a story resolved could be smoother. Right now you kind of have to remember which ones you looked at earlier. A small “resolved” section or history would make that easier.
Overall the core idea works, these are just the parts that feel unfinished.
