How to play Queen Of Rio

In 2009, despite having relinquished any active role in the online gambling industry years earlier, I launched CalvinAyre.com due to my dissatisfaction with the news sites that then dominated discussion of the gaming sector. I found their coverage too deferential to the established giants of the day and too oblivious of the changes I saw looming on the horizon.

Marantelli identifies White Swan and Susquehanna as two firms operating at industrial scale in parlays, with Jump Trading, Mojo and DL Trading among the possible leading group. Below them are numerous smaller syndicates, some managing between $5 million and $10 million, alongside sports-specific specialists.

Enda Kendrick, chief executive of service provider Veltium, similarly says the largest UK and European sharp-betting groups have moved rapidly into US prediction markets. He believes there are also more than 100 smaller operations, ranging from individual traders to teams of around 10, interested in entering the regulated US market.
