What Does It Mean to Tail a Bet? (2026 Guide)
Tailing means placing the same wager as someone whose picks you follow. It is simple to do and easy to do badly, and the most common mistake is invisible, because it hides in the price.
The part nobody mentions: you are probably not getting their bet
If an advisor posts a pick at −110 and you place it at −120, you have not made the same bet. You have made a worse one, and the damage is larger than it looks.
| Price you get | Break-even needed | Your ROI following a 55% handicapper |
|---|---|---|
| −105 | 51.22% | +7.38% |
| −110 | 52.38% | +5.00% |
| −115 | 53.49% | +2.83% |
| −120 | 54.55% | +0.83% |
| −130 | 56.52% | -2.69% |
Tailing a 55% handicapper at −120 instead of −110 destroys 83% of the edge. At −130 you lose money following a winning handicapper.
The advisor record still shows +5%. Yours does not, and nothing on their profile will ever tell you why.
How to tail well
- Check the price before you copy the pick. Compare against the price the advisor actually got. If yours is materially worse, skip it. A skipped bet costs nothing.
- Confirm the exact market and line. A move from -3 to -5.5 is a different bet, not a slightly worse one.
- Use your own unit size. Copy the pick, not their stake. Their bankroll is not yours.
- Bet promptly or not at all. Lines move toward the closing price, and a stale pick is usually a worse one.
- Log every tail. Pick, price you got, stake, result. Your record is not their record, and only your log knows the difference.
Why the posted price matters
This is the practical reason to follow advisors who publish the odds they got, at the moment they got them, rather than screenshots after the fact. Without the original price you cannot tell whether the bet is still worth making, and you cannot tell afterwards whether a bad run was the picks or the prices.
On Betvisors, every pick is posted before the event with the price captured at posting, graded by the platform, and unalterable, so the comparison is always available to you. See how verified records work.
Where Betvisors fits
Follow vetted advisors, tail picks to your own licensed sportsbook, and pay only when a tailed pick wins. We never place the bet or hold funds. You do that at your own book, which is also where you check whether the price still works.

Frequently Asked Questions
Is tailing bets legal?
Following someone picks and placing your own bets at a licensed sportsbook is ordinary betting. Legality depends on your jurisdiction, not on the fact that you got the idea from someone else.
What is the best app to tail picks?
One where records are posted before the event with the price attached, cannot be edited, and shows the sample size, and ideally where you are not paying a subscription during losing stretches.
Does it matter if I get a slightly worse price?
More than almost anything else. Tailing a 55% handicapper at −120 rather than −110 removes about 83% of the edge, and at −130 you lose money following a winner. Always check the price before you copy the pick.
Should I copy their stake size?
No. Copy the selection, not the dollar amount. Use a fixed unit sized to your own bankroll.
