Chalk
The heavily favored team or player in a game or event.
Chalk refers to the heavy favorite in a game, race, or event. Betting chalk means betting the favorite, often at significant negative odds. The term originated in horse racing, where favorites were written on chalkboards before electronic displays.
Why Chalk Matters
Betting chalk consistently is a losing strategy over time. Sportsbooks set lines with the vig built in, and heavy favorites need to win at a high rate just to break even. A -300 favorite must win 75% of the time just to break even.
Chalk vs. Dog
Sharp bettors often find more value on underdogs (dogs) than on chalk, because public money tends to inflate favorite prices. The public loves betting well-known teams and favorites, pushing chalk prices higher than they should be.
Key Takeaways

Frequently Asked Questions
Why is it called chalk?
The term comes from racetracks, where odds were written on chalkboards. The favorite drew the most bets, so its odds were rubbed out and rewritten the most.
Is betting chalk a bad strategy?
Not automatically. Favorites win more often, but you pay more for that. The question is always whether the price is right, not whether the team is favored.
