NFTs and Web3 opportunities delivered some of the largest percentage gains of the year. While higher risk than traditional reselling categories, several projects generated exceptional returns for members who participated early.
While not every opportunity turns into a four-figure return, these examples demonstrate the range of flips available across multiple categories. Whether it was tickets, sneakers, trading cards, Vinted finds, NFTs or in-store exclusives, the common factor behind many of these successes was early access to information.
👉 Throughout 2026, House of Resell members benefited from real-time monitors, stock alerts, release guidance and community discussion that helped identify opportunities before the wider market reacted. With another six months still to come, it will be interesting to see which flips ultimately claim the top spot by the end of the year.
