I think we’re probably a couple of years away although Matched Betting in the United States could be wildly lucrative.
Don’t get too excited though, there’s lots of legislation and issues with the USA and betting. Sheldon Adelson is spending a lot of time and money to stop various things happening.
When you realise he owns a chunk of Las Vegas and is good buddies with Trump it looks even bleaker. A seriously powerful bloke at 34 billion.
I’d like to be optimistic over the medium-long term though, could well happen (and change everything).
