For years, Rosemont served as the reliable, working-class hub of Midwest card shows. Collectors drove in from across the region to dig through quarter boxes of sports cards, hunt down vintage non-sports sets, and pick up raw Pokémon singles from table-top sellers. That community-first model made Collect-A-Con a massive cultural footprint in the first place.
Private equity and commercial event syndicates recognized the cash flow. The massive monetization of live experiences across pop culture prompted large media consortia to acquire controlling stakes in top-tier card conventions. Institutional owners do not operate on passion project margins. When hundreds of thousands of square feet are leased at the Donald E. Stephens Convention Center, every single aisle must generate measurable, recurring revenue. The convention floor now mirrors an equities exchange far more than a swap meet, marked by uniform corporate booths, sponsored creator lounges, and strict branding enforcement that leaves little room for casual barter.
