Colossalcon Texas takes over Kalahari Resorts & Conventions in Round Rock the weekend of August 21-23, 2026, bringing the Austin metro a full anime, gaming, and pop culture convention with a resort-and-waterpark twist. While Colossalcon is best known for cosplay, artists, and its famous poolside atmosphere, its dealer hall and gaming areas make it a strong stop for trading card collectors and TCG players — especially anyone into Pokémon, One Piece, Yu-Gi-Oh!, and the wider world of anime and gaming cards. Held just north of Austin in Round Rock, it is an easy drive for Central Texas collectors and doubles as a destination weekend for families.
In the dealer hall and artist areas, expect vendors carrying Pokémon singles and sealed product, One Piece, Yu-Gi-Oh!, Magic: The Gathering, Disney Lorcana, and Dragon Ball Z, along with graded slabs, sealed wax, anime figures, manga, and collectibles. Sports cards show up too at general collectibles booths — MLB, NBA, NFL, and soccer among them — though the floor naturally skews toward TCG and anime merchandise given the convention's audience. For TCG players, the bigger draw is often the organized and casual gaming space, where you can find pickup games, side events, and fellow players to trade and battle with throughout the weekend.
As a multi-day convention, Colossalcon Texas runs Friday through Sunday, with the dealer hall and programming generally opening late morning and running into the evening Friday and Saturday, and a shorter Sunday schedule. Because it is hosted inside the Kalahari resort, many attendees book rooms on-site to enjoy the indoor waterpark and after-hours programming. Badges are sold as full-weekend passes and, often, single-day options; pricing varies by tier and rises closer to the event, so buying early saves money. Check the official Colossalcon Texas site for exact hours, badge tiers, hotel room blocks, and the confirmed guest and vendor lineup.
Who should attend? Anime and gaming fans, cosplayers, TCG players who want a weekend of side events and trading, and families looking for a resort getaway that pairs a waterpark with a convention. Card collectors focused strictly on vintage sports may find the floor lighter on their niche than a dedicated card show, but Pokémon, One Piece, and TCG collectors will find plenty to dig through and a large community to trade with.
To get the most out of the weekend, buy badges and book your room early, since the on-site resort blocks fill fast. Bring cash for dealer-hall and trade transactions, with Venmo and Zelle as backups, and pack a trade binder of TCG extras — the gaming areas are where a lot of the best deals happen player-to-player. Carry sleeves, top loaders, and a slab case for pickups, and plan your schedule around any can't-miss panels or guest signings.
