ProphetX
A peer-to-peer sports exchange publishing a full time-and-sales tape. This page covers what trades there — daily contract volume, how much of it is parlays, and on single markets whether those prices come true.

Daily volume
Calendar days, not the venue's trading sessions. A ProphetX session runs 16:30–16:30 ET, so its own session labels straddle two dates; using the execution timestamp instead keeps this series comparable with every other venue on the site.
How much of it is parlays

Biggest games by volume
Parlays and tournament outrights are left out because neither belongs to a single game; what remains is 77% of the tape.
What trades there
One row per league and contract type; parlays are a single row because they span games.
Where the volume sits on the probability axis
Parlays by leg count
ProphetX calls them multi-event contracts. They run from 2 legs to 12, and shorter parlays dominate — but the tail is real, and a 12-leg ticket is a very different product from a 2-leg one.
