The mix of contract categories Underdog Exchange lists, day by day.
Underdog Exchange: product mix, day by day
Share answers what the venue is for; contracts answers how big it got. Same buckets as Products across venues.
Underdog Exchange: non-parlay sports vs parlays
Underdog Exchange: volume by category
All time, in contracts. Share is of this venue's whole volume, so the bars add to 100%.
Every bucket, all time
How the buckets are built
Categories are rolled into seven shared buckets so venues can be read side by side. The taxonomy is broad because the broadest venue sets the ceiling — Kalshi publishes one Sports value where others name the sport, and inventing a split for it would be fabrication.
“Other” is not one thing. At Underdog it is the combo bucket; at OG/Crypto.com and DKeX it is a genuine residual, and OG/Crypto.com carries a separate explicit Parlays value. It is mapped per venue rather than globally.
