The price that is better than the market
An offer that quotes better odds than the same selection carries everywhere else is the most common promotion in sports betting and the least examined one. This desk takes the uplifted price apart: what moves it, the maximum stake that qualifies for it, what the uplift is worth when the stake is larger than the cap, when the price goes back to the market one, and how to check it before taking it.

An uplifted price is an offer that quotes better odds than the same selection carries at the market price, in exchange for terms: usually a ceiling on the stake that qualifies, a fixed set of selections, and a window. The price is genuinely better; the cap is what decides whether the improvement is worth anything to you.
1,200 uplifted prices offered to sampled accounts, sorted by the shape of the offer: a single-selection price boost on 540 (45.0%), an acca boost on 288 (24.0%), a boost applied by a token on 228 (19.0%) and a market-wide boost on 144 (12.0%). The whole desk is about the one thing all four do - quote a better price than the market for the same selection.

The 540 single-selection boosts, market price against boosted price: 240 moved 2.50 to 3.00 (+20.0%), 156 moved 4.00 to 4.50 (+12.5%) and 144 moved 1.80 to 2.00 (+11.1%). The mean market price was 2.75 and the mean boosted price 3.17, a mean uplift of +15.3%, and the mean implied chance of the selection fell from 39.8% to 34.6%.

What the uplift pays. On the 2.50 to 3.00 boost a 10.00 stake returns 30.00 boosted against 25.00 at the market price, so the uplift pays 5.00 if the selection wins. Averaged over the two outcomes at the market own implied chance of 40.0%, the boost adds 10.00 times 0.50 times 0.40 = 2.00 of expected value on a 10.00 boosted stake - 20.0% of the stake it is applied to.

Nearly every offer carries a ceiling on the stake that qualifies. Of the 540 boosts, 372 capped the qualifying stake at 10.00 (68.9%), 120 at 20.00 (22.2%) and 48 at 50.00 (8.9%) - a mean cap of 15.8. The whole stake qualified on just 168 of the 540 offers (31.1%).

The cap fixes what the uplift is worth, not how much is staked. At a 10.00 cap the 2.50 to 3.00 boost adds the same 2.00 of expected value whether the stake is 10.00 or 100.00 - which is 20.0% of a 10.00 stake and 2.0% of a 100.00 stake. The stake above the cap is simply taken at the market price.

An acca boost raises the combined price by a step that grows with the number of legs: +5.0% at 2 legs (72 of 288), +10.0% at 3 (96), +15.0% at 4 (84) and +20.0% at 5 or more (36), a mean of 3.4 legs. With every leg at 2.00 the mean combined price is 12.33 and the boosted price 14.15 (+14.8%); at three legs the implied chance of all three landing falls from 12.5% to 11.4%.

Not every boosted price is paid at the boosted price. Of the 540 boosts, 462 were settled at the uplifted price (85.6%) and 78 were not (14.4%): 34 because a selection changed or was withdrawn, 22 because the market was resettled before the stake was placed, 14 because the boosted selection was not in the final slip, and 8 because the operator declared a palpable error.

One offer carried through: market price 2.50, boosted price 3.00, a 100.00 stake and a 10.00 cap. If it wins, 10.00 at 3.00 returns 30.00 and the other 90.00 at 2.50 returns 225.00 - 255.00 against the 250.00 the same stake would have returned at the market price, so the uplift paid 5.00 on a stake twenty times its cap.

A month of taking boosts: 540 offers at a mean stake of 20.00 is 10,800.00 staked. At the mean uplift and the mean cap, each offer adds 2.42 of expected value, so the month adds 1,304.00 - 12.1% of the stake - and only 168 of the 540 offers had the whole stake boosted.

One number moved, and everything that hangs off it
A price boost is not a bonus and it is not a free bet. Nothing is added to the account and nothing is subtracted from it. What changes is the number attached to a selection: a football team priced at 2.50 across the market is offered to you at 3.00. If the selection wins, the difference is paid in full. If it loses, the boost paid nothing and cost nothing.
That is the whole promise, and it is a real one. The catch is never the price. The catch is everything printed around it: the stake that qualifies, the selections that are eligible, the window, and the conditions under which the operator may settle at the market price instead.
This desk prices all of those. Every figure on it derives from ten invented samples defined below, and every arithmetic step is shown so it can be re-derived. Nothing on it is observed from a live offer, and no operator, market, team or person is named.
The arithmetic in one line, and then in a paragraph
Worked example / sample C
- the market price of the selection: 2.50
- the boosted price of the same selection: 3.00
- a 10.00 stake, fully within the cap
- at the market price: 10.00 x 2.50 = 25.00
- at the boosted price: 10.00 x 3.00 = 30.00
- the uplift if the selection wins: 5.00
- the market own implied chance: 1 / 2.50 = 40.0%
- the added expected value: 10.00 x 0.50 x 0.40 = 2.00
Read the last line of that box carefully, because it is where most of the misunderstanding sits. The boosted price moves money only when the selection wins. Averaged across the win and the loss it is worth a fraction of the headline difference, because most of the time it is not paid at all.
What the desk covers, in the order the questions arrive
| Question | Where it is answered | Figure |
|---|---|---|
| What actually moves? | the uplift itself | +15.3% |
| What is it worth? | what the uplift is worth | 2.00 |
| How much may I stake on it? | the maximum stake | 15.8 |
| When is it not paid? | when the price goes back | 14.4% |
| How is it settled? | settlement at the boosted price | 74.0% |
The order matters. A reader who starts at the cap and works backwards arrives at the arithmetic already knowing why the arithmetic is the point.
How to use this desk
- Read the answer block at the top of a page first; it is written to be quoted, and it contains no arithmetic.
- Read the worked example second; every number in it comes from the ten samples and every step is shown.
- Treat every figure as illustrative. The samples are invented, and the desk never describes a real offer.
- Check the cap before the price. The uplift is only worth what a stake inside the cap can win.
- Do not treat any of this as advice on whether to take an offer. It is a description of how one works.
