Its chief executive, Jason Trost, 35, started the company in 2008 in an attempt to undercut traditional bookmakers by applying financial trading principles to sports betting. Since then, more than £3bn has swapped hands on its exchange, helping sales grow to £10.4m in 2015. Smarkets has raised £2.5m from investors and is now reportedly considering a stock market flotation in New York.
