How Betting Odds Compare on New and Established Betting Sites
In that one instance, there isn’t. If you’re looking for the best odds on that one market then a price comparison site does the job pretty efficiently. However, if you don’t want to end up with an account at 600 different sports betting sites, then looking for a bookie that consistently prices well is a better use of your time.
After all, one set of odds is a price, a whole market of odds is a reflection of how a bookmaker builds markets. Compare one selection and often a new betting site looks sharper. Compare the full experience and it’s often a little different.
The Best Price Illusion
Sometimes an example is the best way to get a point across and perhaps that’s never been truer than with headline market odds.
- A new site offers 2.20 on a Premier League favourite.
- An established bookmaker sits at 2.10.
It’s clear that the new site offers better value, but only on this market.
New operators often use selective overpricing, or loss leaders, in order to attract attention. That means you’ll often find one or two outcomes in a high-profile match are pushed above the market.
But, once you’ve made that account and you’re looking for your next (less high profile) bet, the rest seem to be priced more conservatively. This matters a lot to your bankroll, as plenty of your bets won’t be in those overpriced markets.
Why Do New Sites Often Look More Competitive?
One of the simplest ways for new sites to stand out in a crowded and highly competitive market is to offer enhanced prices on those key fixtures. Throwing in odds boosts helps even more. After all, if you’re having a reasonable bet on a big match, you want to get the best odds.
Those prices are only there to get feet through the door. So how do they afford it?
- Slightly lower odds on secondary markets
- Less competitive accumulator pricing
- Tighter maximum stakes
That last point is particularly important. If those brilliant headline odds have a maximum stake of £5, but you can have £200 at a well-established site, those headline odds might not be ‘better’ after all, just higher.
In this way, you can think of those unexpectedly generous odds and odds boosts as redistribution. It doesn’t mean that they’re bad value, in fact all promotions in the UK have to run in line with guidance[1], it just means they need context. If the headline price is good, but all of the other prices are just a little below good, then this won’t translate to better long-term pricing.
Established Operators Lose the Battle but Win the War
Established operators don’t tend to win the headline battle so often. Instead, they compete across depth and consistency.
Established bookmakers are more likely to offer odds on the widest range of markets, like:
- Match odds
- Over/under lines
- Player shots, assists, and bookings
- Corners and cards markets
- Custom bet builders
A newer site may offer a much narrower range. Pricing becomes harder as markets expand. That means it’s pretty easy to compete on three outcomes, but much harder to stay competitive across 200.
Established bookmakers tend to have the edge in terms of data models and trading infrastructure. This means that while those headline odds might not be the best, you’re getting better market depth and often a fairer, more consistent price on secondary markets.
In-Play Betting Is the Real Test
If you’re a keen in-play bettor then you may have already noticed that established betting sites are able to offer a stronger live betting offering. That’s because live markets require:
- Rapid data processing
- Constant price adjustment
- Confidence in risk exposure
Newer sites can’t always reliably offer this, so you’ll sometimes find that they:
- Suspend markets more frequently
- Lag behind fast-moving events
- Offer fewer in-play options
If live betting is important to you then this is arguably the largest benefit of choosing an established site - or an exceptional new one that is known for its standout live betting offering.
