Nowadays, it seems to me more promising to expand the casino with a prediction market than with a betting shop. I've already seen this in some casinos. To some extent, this is even easier than a bookmaker's office, since you do not need to calculate the bookmaker's odds (or take them from the odds provider).
And technically, this is also easier for casinos, since it does not require functioning on the blockchain like conventional prediction markets, but simply as an additional section in the general casino functionality.
Prediction markets like sports betting or what?
Betting shops are not more profitable than they used to be because casino platforms has made everything easy for bettors so that they can’t expose themselves to the community as gamblers, they can now bet on the comfort of their homes.
Casino platforms are trying to always improve their activities, and once they get recognized they tends to add more games for their users to be comfortable; I think that’s why some of us are expecting sport betting to be added to Vega bet since they are posting about sports in their social media handles.
Prediction markets have sports betting, but the betting system is different from bookmakers. As such, there are no betting odds, but there are chances (expressed in %) that depend only on the amount of bets placed by bettors on the outcome of the event. This simplifies and reduces the cost of the betting system.
And by the way, this is more accurate because there is no line movement in the prediction markets to balance the odds in the interests of the bookmaker, and the odds are not affected by the bookmaker's margin. On average, the accuracy of prediction markets is about 90% (Polymarket).
So it is possible to expand the casino with the prediction market more promising and profitable than to expand casino services by creating a betting shop.
