Line shopping means checking several sportsbooks (or prediction markets) and placing your bet wherever the price is best. It's boring. It also works.
Why it matters
Say you bet $100 a game at -110. Each win pays $90.91. Now say you got -105 instead: each win pays $95.24. Over 100 winning bets that's about $433 more, just from picking the right app.
Same with spreads: getting +3.5 instead of +2.5 in football turns a lot of losses into wins.
How to do it
- Have accounts at 2–3 sportsbooks (and Polymarket or Kalshi if they're available where you live).
- Before every bet, check the price everywhere.
- Take the best number. Every time.
Bonus: compare books with prediction markets
If Polymarket has a team at 55¢ and a sportsbook has them at +110 (about 47.6%), that's a big gap. It's either a great bet at the book or a sign the market knows something.
Where AlphaPredict fits
Line shopping finds the best price. AlphaPredict tells you which side is worth it. Screenshot the best line you found and scan it before you bet.
Key takeaways
- Same bet, better price = more profit
- Small differences add up over a season
- Combine line shopping with a solid pick
The bottom line
Line shopping won't make headlines, but it's the closest thing to free money in betting. Never take a worse price just because it's the app you already have open.
