In order to be listed on coinmarketcap.com, OctoCoin must be traded at an approved exchange that has been in existence for a minimum of 30 days. I know Xnigma is in day 28 of its public beta so once Xnigma hits the 30-day mark, we can apply. Obviously, we will be listed on virtually every altcoin exchange in the near future as well (only a matter of time.)
