People participating in competition and winning (or not) are in my opinion self driven individuals that are more suited to build their own company as opposed to be a good employee.
I can't see how being talented at this would have any connection to talent at building a company, in fact I wouldn't be surprised if it was negatively correlated. I'm not really sure talent at winning programming competitions could be positively linked to other than talent at winning programming competitions. Valuable industry tasks differ substantially from what is done in a programming competition.
