Track where meaningful market movement creates a gap between fair value and the price still available at retail books. Whale Watch helps you evaluate the signal, compare context, and decide whether the number is still worth your attention.
What Whale Watch helps you review
Who this tool is for
Coverage depends on supported books, markets, and user location
Supported retail sportsbooks and sharp reference markets where Upside has current coverage.
Major sport markets vary by schedule, book availability, and user location.
Upside scans 30+ sportsbooks, DFS apps, exchanges, and prediction markets across the product, but each tool has its own coverage rules and data availability.
What to check before making your own decision
Start with the move, not the alert
Use Whale Watch to see which side moved, when it moved, and how much retail price is still available. A move matters only if the current price still leaves enough room to evaluate.
Check the book context
Review whether one retail book is lagging or several books are still slow to adjust. Wider confirmation usually gives the signal more context than one isolated stale number.
Compare with Odds Screen or calculators
Use the Odds Screen, EV Calculator, or Implied Odds Calculator to translate the move into probability and price before making your own decision.
Track the result
Judge Whale Watch by closing-line value and process quality. The tool is meant to help you review market movement with discipline, not chase every green row.
Before relying on the data
- Is the current retail price still close enough to the signal price to justify more review?
- Do multiple books confirm the move, or is the row driven by one slow market?
- Does the edge still make sense after converting the price to implied probability?
Common Whale Watch questions
What is Whale Watch?
Whale Watch is Upside's public-facing sharp money tool. It helps users review market movement, fair-value gaps, and retail book lag across supported betting markets.
Does Whale Watch place bets for users?
No. Whale Watch is read-only analytics software. Upside does not accept wagers, operate a sportsbook, or place wagers on a user's behalf.
What should users verify before acting on a signal?
Users should verify the live price at the sportsbook, confirm the market is still available, check whether multiple books support the move, and decide whether the price fits their own risk limits.
How does Whale Watch fit with the rest of Upside?
Whale Watch is strongest when paired with Odds Screen and the calculators. It can flag a move, while the supporting tools help users review price, probability, and market context.
