A discussion this week caught my attention because it introduced a brand-new platform that approaches the business from a completely different angle. Instead of charging a commission on every card sold, the seller pays for the audience itself. One example mentioned a three-hour livestream with around eighty viewers costing approximately $74. Another example put a twenty-five viewer stream at just over $28.
Something interesting has been happening over the past few months. For years, platforms like eBay and more recently Whatnot have become the default places to buy and sell sports cards. Most collectors simply accepted the fees as part of doing business. You sold a card, the platform took its percentage, and you moved on.
From Transaction Fees To Subscription Economics
Traditional marketplaces make money every time a seller completes a transaction. Sell more cards, pay more fees. This new model flips the equation.
Instead of taking a percentage of every sale, the platform charges based on usage. Once the stream is running, it makes little difference whether you sell ten cards or one hundred cards. Suddenly, volume becomes an advantage instead of a penalty. I understand why that sounds attractive to experienced sellers.
Someone moving thousands of dollars every week quickly notices the difference between paying seven or eight percent on every transaction and paying a fixed operating cost for a livestream. Of course, that only works if enough buyers actually show up.
Network Effects Are Hard To Beat
This is where every new marketplace faces the same problem. Collectors rarely choose platforms because of lower fees. They choose platforms because that is where everybody else already is.
One seller in the discussion made exactly that point. He was not particularly concerned about Whatnot’s fees because the platform had already generated thousands of successful sales for him. From his perspective, the commission was simply the cost of reaching a nationwide audience.
The best pricing model in the world means very little if the buyers never arrive.
AI Is Already Entering Live Selling
The platform is experimenting with AI-supported livestreams. Instead of sitting in front of a camera for hours waiting for enough bidders to join, sellers could eventually allow AI to run parts of the show, schedule auctions or automate repetitive tasks.
One commenter immediately dismissed it as “another AI app.” Others were more interested in the marketplace itself than the AI features. That reaction tells us something important. Collectors may be willing to accept AI as a tool, but they still seem to value the personality of the breaker or seller. The hobby has always been built around trust, conversation and entertainment as much as the cards themselves.
The Real Winner Might Be Competition
The more interesting development is that entrepreneurs now believe there is room to challenge Whatnot at all. That would have sounded unlikely only a few years ago.
Competition usually forces established platforms to react. Lower fees, new tools, better seller support or improved marketplace features suddenly become much more likely once sellers have credible alternatives.
Selling Cards Is Becoming A Business
Sometimes collectors forget how much the hobby has changed. Selling a few duplicate cards on eBay is one thing. Running nightly livestreams, managing inventory, calculating fees, monitoring shipping costs and building an audience is something completely different. Many breakers now operate businesses rather than hobbies, and businesses naturally optimize costs. That explains why discussions increasingly revolve around percentages instead of cards.
The irony is that the cards themselves have almost become secondary. The real competition is no longer between Michael Jordan and Shohei Ohtani. It is between marketplaces fighting over the right to facilitate those sales. And that may become one of the most interesting battles in the sports card hobby over the next five years.
