One ever underrated challenge with prediction markets is creating clear and concise rules for interesting questions, while the easy part is the tech powering the exchange.

For example, "James McIntyre is predicting that: There will be a global stock market crash in 2024." What constitutes a crash here? Or "Patricia Davenport is predicting that: An absolutely massive natural gas discovery will be made by a Southern African country before the end of 2023." has no clear meaning.
