Liquidity challenges on low-volume markets

Stefan Stadie is a professional sports trader at Kero Sports whose work sits at the intersection of equities, sports betting, and prediction markets.

After starting his trading journey in equities, Stefan evolved toward a more process-driven approach focused on price, liquidity, and market behavior. Today, his edge comes less from predicting outcomes and more from identifying mispricing, capturing inefficiencies, and operating across multiple markets in real time.

In this conversation, Stefan shares how the same principles—crowd psychology, liquidity, and price discovery—show up across different environments, from stocks to sports to decentralized prediction markets. He also walks through his transition into arbitrage and market making, how he approaches risk, and what it takes to stay disciplined when operating in fast-moving, competitive markets.

This episode offers a different lens on trading—one that challenges traditional thinking around prediction, edge, and where opportunity actually comes from.

In this episode, we explore:

·        Why trading principles can transfer across completely different markets

·        The role of liquidity and crowd behavior in shaping price

·        Moving from directional trading to arbitrage and market making

·        How mispricing creates opportunity across fragmented markets

·        The reality of being limited or banned by sportsbooks

·        Differences between traditional financial markets and emerging prediction markets

·        Managing psychology and discipline in fast-moving environments

·        Why focusing on price—not opinion—can change your approach to trading
