The maximum stake
Almost every uplifted price caps the stake that is taken at the better price, and the cap is where the offer stops being a better price and becomes an ordinary one. This page shows what the cap is, what the sampled caps were, and how the stake above the cap is settled.

The maximum stake is the ceiling on how much of your bet receives the uplifted price. Stake above it is taken at the ordinary market price. A cap therefore fixes the extra value an offer can add, however much you stake: it does not scale with the bet.
The cap is a ceiling, not a limit on your bet
An offer with a 10.00 cap does not stop a 100.00 stake. It takes the first 10.00 at the boosted price and the remaining 90.00 at the market price. The bet is the same bet; only the pricing of it changes above the line.
| Qualifying stake | Offers | Share | Running mean |
|---|---|---|---|
| 10.00 | 372 | 68.9% | 10.00 |
| 20.00 | 120 | 22.2% | 12.44 |
| 50.00 | 48 | 8.9% | 15.78 |
| the mean cap | 540 | 100% | 15.8 |
Roughly two offers in three capped the qualifying stake at 10.00. That is the number worth carrying into any comparison: on a 10.00 cap, the whole benefit of the offer is available on a ten-unit stake and no more.
What the cap does to the arithmetic
Worked example / sample I, a 100.00 stake against a 10.00 cap
- market price 2.50, boosted price 3.00, cap 10.00
- the capped part: 10.00 x 3.00 = 30.00 if it wins
- the uncapped part: 90.00 x 2.50 = 225.00 if it wins
- total returned if it wins: 255.00
- the same 100.00 at the market price throughout: 250.00
- what the uplift actually paid: 5.00
The cap is therefore the correct answer to the question an offer never answers: how much is this worth to me. It is worth the same amount at every stake above it, and that amount is smaller the larger the stake is measured against.
Reading a cap before a price
- Find the qualifying stake before the odds. It is usually in the conditions rather than beside the price.
- Assume the cap is the smaller of the qualifying stake and what you intend to bet.
- Compare offers on the capped stake, not on the headline price. Two offers at the same price with different caps are different offers.
- Remember the stake above the cap is not penalised, just priced normally - see settlement at the boosted price.
- Where the whole stake qualified in only 31.1% of the sampled offers, assume the cap applies unless the offer says otherwise.
