Understanding Inefficiencies in Sports Betting


Welcome to Atrium Bets! I’m the Atrium, and today we’re diving deep into the world of sports betting, specifically focusing on inefficiencies in the market that can impact your betting strategies. It’s mid-August 2023, and it’s been a tough six weeks for many bettors. We’ve been analyzing what’s gone wrong and how to navigate these choppy waters.

As data-driven bettors, it’s crucial to figure out whether our current struggles stem from short-term variance or if there’s something fundamentally wrong with our approach. Recently, I conducted a live stream where I analyzed our betting patterns and identified a shift in the market—particularly with FanDuel—that has disrupted our calculations.

What is a Historically Mispriced Market?

The key takeaway from our analysis is the importance of recognizing historically mispriced markets. This isn’t just about positive expected value (EV) betting; it’s about understanding the broader landscape in which these bets are placed. In the case of FanDuel, they’ve adjusted their offerings in a way that can mislead traditional positive EV calculations.

For example, we observed that FanDuel has shifted to a model where many of their player props only offer over bets. This change, while seemingly minor, has significantly affected the outcomes for bettors like us. It’s essential to understand that these adjustments can skew our strategies and lead to losses even when we think we’re making the right bets.

Analyzing the Shift in Player Props

Let’s take a closer look at an example. Consider Carlos Santana’s player prop, which was listed at +160 on FanDuel, while other books were offering significantly lower odds. Normally, this would scream to us to take the bet based on a positive EV strategy. However, we must ask ourselves: is this a trap? Are we falling into the recency bias trap, believing that just because the line looks good, it’s a sure win?

Although our calculations suggested that this was a solid play, anecdotal evidence from other bettors indicated that these inflated lines were not coming through as expected. So, what do we do? We need to approach these situations with caution and a critical eye.

Strategies for Sharp Betting

Here are a few strategies to consider when navigating these market inefficiencies:

  • Stay Data-Driven: Always rely on statistical data to guide your decisions. The law of large numbers suggests that short-term variance can lead to misleading conclusions.
  • Evaluate Market Changes: Keep an eye on how sportsbooks adjust their lines. If a book like FanDuel starts leaning heavily on one side, it may indicate a strategic shift that could lead to mispriced opportunities.
  • Test Your Hypotheses: If you suspect that a market is mispriced, test your hypothesis with smaller bets before committing larger amounts. This approach helps to gather data without risking significant losses.

Finding Opportunities in Mispricing

As we’ve seen, FanDuel’s shift may not necessarily indicate that they’ve become better at setting lines. Instead, they may be leveraging the betting habits of the public to their advantage. This raises an important question: how can we turn this to our benefit?

By identifying plays where we can go against these one-sided lines, we may find opportunities that others overlook. Remember, if the market isn’t efficient, there’s always a chance to capitalize on mispricing.

Conclusion

In conclusion, understanding market inefficiencies is essential for any serious bettor. The recent changes we’ve seen, particularly with FanDuel, highlight the importance of adapting our strategies and remaining vigilant. As we continue to analyze the data and refine our methods, we can improve our chances of success in this ever-evolving landscape.
