How do prediction markets work?

As we already mentioned earlier, predicting market sites don't work in the same manner as sportsbooks. Instead of regular lines, it offers digital shares that depict the outcomes of future events.

The prices attached to each share indicate what various traders believe the likelihood is of the event occurring. Prices are usually affordable, starting from $0.1 up to $1, meaning anyone can get in on the fun and start making predictions.

Higher-priced shares imply a higher probability of the event occurring, while the reverse is true for lower-priced options. For example, if a share is priced at $0.20, it means there is a 20% chance of the event happening, while one priced at $0.70 indicates a 70% likelihood of the event taking place.

By purchasing any shares, you are basically supporting the prediction and agreeing that it is correct. If your prediction turns out to be correct once the market settles, your shares become $1, while they become $0 if your prediction is wrong. We recommend having a look at our guide, where we explain what event trading is extensively.
