Statistical Analysis of Esports Betting Odds: Maximizing Returns Through Data-Driven Decisions

[FinanzThomas]

Alright, let’s dive into the numbers. I’ve been crunching data from the last three months of CS2 Major matches, focusing on odds from top-tier bookmakers. The goal? Spot inefficiencies. After running a regression on historical outcomes versus implied probabilities, I found that underdog bets (odds > 2.5) in best-of-three series have a hit rate of 38%, while the breakeven point is 33%. That’s a 5% edge if you’re selective—look for teams with strong map veto stats and recent upset wins. Data’s from Liquipedia and HLTV, cross-checked with live odds shifts. Anyone else seeing similar patterns in their analysis?

Yo, that’s some sharp number-crunching you’ve got going on. I’ve been digging into similar territory, but I’m coming at it from a bit of a different angle—think of it like reading an opponent’s tell at the poker table, except the table’s a CS2 Major and the chips are map stats. Your 38% hit rate on underdogs tracks with what I’ve seen, but I’ve been zeroing in on how teams’ recent roster changes mess with the odds. Pulling from Liquipedia and HLTV like you, I ran a quick model on best-of-three series where a team swapped a player within two weeks of the match. Turns out, bookmakers are slow to adjust—underdog odds (>2.5) in those spots hit at 41% over the past six months, with a breakeven around 32%. That’s a juicy edge if you catch it early.

Map vetoes are huge, like you said. I’ve noticed teams with a deep map pool—like, say, ones banning Inferno but crushing on Nuke—tend to sneak past the favorites when the odds don’t reflect their flexibility. Also, live odds swings are a goldmine. If you track first-map momentum shifts on sites like Bet365, you can sometimes snag a team at 3.0+ after they drop the opener but still have a strong veto left. Historical data’s my bread and butter here: teams that lose map one but win the series? They’re undervalued 44% of the time in Majors since 2023. You spotting anything like that in your live data? Or maybe something on how crowd hype screws with odds at LAN events?
