Lesson Learned: Polymarket vs. Traditional Sports Betting Mindset

Was looking back at a few Polymarket resolutions from earlier this year, specifically some political and entertainment markets. I'm primarily a sports bettor, and I think I carried over too much of that mindset into Polymarket, treating it like a traditional book. The key difference, which seems obvious in retrospect, is the liquidity and the ability to exit. In sports betting, once you're on a line, you're on it unless you can find someone to buy your position, which is rare. Polymarket's ability to trade in and out means the optimal strategy is often about finding value early and then managing the position as the probabilities shift, rather than just taking a final stand. I had a couple of instances where I saw the market move against my initial bet and just held, thinking 'my pick is still good,' when a partial or full exit would have mitigated losses significantly. It's not about being right all the time, but about maximizing probability-adjusted returns. Definitely a different beast and I'm still adjusting my approach, especially on how to scale in or out of positions without getting chopped up by fees.
