Who Owns Spreadex?
Spreadex is owned by a company of the same name, Spreadex Limited. Despite operating across just the one domain, there are actually seven trading names that make up the Spreadex brand with the UK Gambling Commission.
It is the headline brand in spread betting, however, it also provides a more traditional fixed odds betting platform to punters with licences dating back 16 years.
Experience counts for a lot. It isn't everything, though, and the sportsbook arena is a highly competitive one. Will any of the Spreadex sister sites or alternatives measure up?
What Are the Spreadex Pros and Cons?
If you're interested in sports betting then Spreadex provides a host of positives for you. The fixed odds side of the site provides betting margins of 6.35%, which is more than acceptable.
Those odds allow you to dabble across all the top sports, knowing you're not getting ripped off, while you have strong market depths to explore too. Premier League football matches, for example, boast in excess of 300 markets. That is stronger than most.
It's not all good news, though. Whilst top sports are available, the sports A-Z caps out at 23 sports. There are sites that can boast double that footprint with real niche sports covered, and most bookies will eclipse the 30 mark.
There is, however, an excellent array of in-play markets and the offer of live streaming is something that is lacking with a fair few bookmakers.
Withdrawal processing at Spreadex is excellent too. Our tests saw funds returned to our bank account in just four minutes.
The limited range of payment options, however, is a bit of a miss. There is also the very recent news of Spreadex pulling out of the casino market, which is a real disappointment for punters who like a rounded offer.
Spreadex Sister Sites & Alternatives Reviewed
Spreadex isn't the perfect platform but it is a damn tidy sportsbook, both with fixed odds and the flexibility to toggle over into spread betting at the touch of a button. In the modern day, though, you are spoilt for choice when picking a bookmaker.
These Spreadex sister sites and alternatives may well tempt you for an exploration in new lands.
Sporting Index
Sporting Index and Spreadex have been in the news together for a while now, courtesy of Spreadex's purchase of the former.
Officially, Sporting Index is a Spreadex company, albeit registered under a standalone UKGC licence. The CMA are not overly sold on the deal but, nonetheless, right now, Sporting Index is the leading sister site. You can tell too.
Sporting Index is a really tight replica of Spreadex. That is clear from the initial look and feel of the site, which is a good thing because the site is easy to navigate, with intuitive menus and smart labelling.
The continuity between the two sites runs much deeper than that, though. Sports coverage is identical, the odds are the same and both offer spread betting alongside traditional sports wagering.
A tiny difference is that Spreadex are killing the casino, while Sporting Index have never offered one.
BetTom
BetTom is not a household brand name like Spreadex, but it certainly stands up against it well when side-by-side.
The banking methods, while limited, are equal to what is offered at Spreadex but punters can get started for just £1, while the withdrawal timescale of only two minutes is going to be hard to beat for all bookies.
In respect of the actual detail, the pool of sports available to bettors at BetTom is superior too. There is still good market depth available and the actual sports available to bet on are more extensive.
Betting margins also go in BetTom's favour with margins of 5.29%; that isn't a market-leading margin, but you don't get many operators coming in better than that.
You do not have the capability for spread betting at BetTom, however, it does boast a casino as a point of difference. There you will find multiple software providers underpinning a couple of thousand games, including several recognised brands.
It is not all upside, though. Getting used to the colour scheme at BetTom takes a little bit of effort with the site cutting a fairly cheap look. It is user-friendly, on the other hand, and moving around the site is very simple.
bet365
Spreadex is a colossus of the spread betting market, giving it significant privilege where factors like reach, site design and market exploration come into play. With that in mind, how about considering another big boy as a direct Spreadex alternative? Bet365 fits that bill for us.
Bet365 does not give you the spread betting option. What it does give you is a safe and protected environment, and one that puts 40 sports and hundreds upon hundreds of markets as your fingertips.
Live streams are commonplace too, more so than at Spreadex, and 5.40% betting margins are another string to the bow.
On top of that, the casino offering at bet365 is pretty meaty too. Games range from big brands like "Big Bass Reel Repeat" and "Eye of Horus" through to bet365 exclusives.
If that isn't enough to convince you, maybe the payment details might help. Deposits and withdrawals start from £5, with deposits instant and withdrawals taking under an hour in our tests.
