I feel like they will not provide the odds out of thin air, they will probably use odds from some other place even if it is not provided by another place. Think about it this way, if you build the whole sportsbook from zero and you basically write all the code without any help from any other company, that is still purely yours, even if you just go check the odds in other places and write that down, that is still yours, there is really nothing to worry about there.

Plus gambling creates its own odds, you see people gambling on one side more than the other and make that work too, I have seen decentralized sportsbooks where people gamble on one side or other and decide on odds without sportsbook deciding the odds, and that was worse, so I think this one will probably be a lot better. It will use comparisons of course but you can't just beat everyone and be best odds at everything, it would be hard, maybe few but not all.
