How big is the parlay book?

COMBOS — OG/Crypto.com's multi-leg parlay product — is the exchange's largest single product line. Adoption over time and volume in contracts; the win/loss question lives on Parlay outcomes.

Parlay adoption history

Monthly share shows the launch without placing a one-venue case study in the cross-venue comparison.

Parlay volume

The same product in contracts rather than as a share, so a busy month is visible as a busy month.
