Overlay Bets

Verified sports tipster marketplace. Picks are cryptographically locked before kickoff, so track records can't be faked. Bettors follow tipsters ranked by real ROI and Closing Line Value (CLV) — not screenshots.

Tagline: Find the overlay. Beat the close.

An overlay is a bet where the offered odds are higher than the true probability warrants — a positive expected value (+EV) bet. Our platform proves which tipsters consistently find them.


Why this exists

Most tipster sites are unaccountable — losing picks get deleted, records are cherry-picked screenshots, and "guaranteed wins" are scams. Overlay Bets makes every pick immutable and independently gradable:

  • Picks are hash-locked + timestamped before the event starts.
  • Settlement is automated from a sports-data API — tipsters can't edit results.
  • Rankings use CLV, the metric that actually separates skill from luck.

We sell data, tools, and picks — we do not take bets (keeps us out of gambling licensing in v1).

The moat

You cannot fake, edit, or delete a losing pick.

Every design decision serves that one principle.
