Reddit makes money primarily through selling advertising space, as well as, an optional premium membership plan for $5.99/month. In order to advertise through reddit, an advertiser has to place a ‘bid’ for space on the site. The minimum bid for ad space is $3.50. However, if you want your ad directly managed by Reddit’s sales team, the bid starts at $50,000.

A premium member can chose to turn these ads off.
