One of our favorite topics here at Odd Lots is market structure. On multiple occasions, for example, we've talked about how trading bonds is fundamentally different than trading stocks. This week our guest is Josh Luber, who has built a market for a non-financial asset: sneakers. The market for collectible sneakers (like Air Jordans) is worth over $1 billion, but it's very hard to get transparent pricing, in part because the action happens across a variety of different sites and venues. Luber explains how his startup StockX wants to unify the industry, bring about transparency, and fundamentally change how this market works.
