How can
Betfair "create them"
They are just there as a tool for people to put their prices up.
The only way they could "create" a price is by putting up the money for someone to take the bet. In other words they'd be gambling against whoever took the price that they created and that would be fuckin stupid as they are making money without having to gamble.
And yes, I believe it would be against the rules if they don't hold a licence as a bookmaker but that's not why they don't do it. It's because it's a stupid idea.
