After you have received your alert that your domain(s) are available, you must return to complete your transaction. There is some misrepresentation about the ultimate cost of your new gTLD. Some media sources have reported that the cost of such a domain will be upwards of $100,000 and this is not the case.
If you are returning to purchase a domain like www.sport.sports the cost in most cases will be what the average domain name costs now.
A company that intends on owning and managing all of the .sports TLDs might pay the suggested $100K+
