It's high stakes for UK firms as sports betting wagering starts to spread out in America.

From Tuesday, new rules on wagering entered impact in Delaware, a small east coast state about two hours from Washington.

Neighbouring New Jersey could begin accepting sports betting bets as early as Friday.

The changes are the very first in what could become a wave of legalisation after the Supreme Court last month cleared the method for states to allow sports betting.

The industry sees a "once in a generation" chance to establish a brand-new market in sports betting-mad America, stated Dublin-based monetary analyst David Jennings, who heads leisure research study at Davy.

For UK companies, which are facing combination, increased online competition and harder guidelines from UK regulators, the timing is particularly appropriate.

Why the betting industry deals with an unpredictable future

How does unlawful sports betting work and what are the fears?

But the industry states depending on the US remains a dangerous bet, as UK business deal with complicated state-by-state guideline and competitors from entrenched regional interests.

"It's something that we're actually concentrating on, but equally we do not wish to overhype it," stated James Midmer, spokesman at Paddy Power Betfair, which just recently bought the US dream sports site FanDuel.

'Take some time'

The US accounted for about 23% of the world's $244bn (₤ 182bn) in gaming profits last year, according to a report by Technavio, external published in January.

Firms are intending to tap into more of that activity after last month's decision, which overruled a 1992 federal law that barred states beyond Nevada and a couple of others from authorising sports betting.

The judgment discovered the law was an over-reach of federal power. But the court it did not really legalise sports betting wagering, leaving that question to local lawmakers.

That is anticipated to cause substantial variation in how firms get certified, where sports betting can take place, and which occasions are open to speculation - with big ramifications for the size of the marketplace.

Potential earnings ranges from $4.2 bn to practically $20bn each year depending on aspects like the number of states move to legalise, Oxford Economics estimated in a 2017 study for the American Gaming Association.

"There was a great deal of 'this is going to be big'", said Will Hawkley, London-based head of leisure for experts KPMG.

Now, he stated: "I think many people ... are looking at this as, 'it's an opportunity but it's not going to be $20bn and it's going to be state by state and it's going to take time'."

'Remains to be seen"

Chris Grove, handling director at Eilers & Krejcik Gaming, predicts that 32 states will legalise sports betting in some form by 2023, producing a market with about $6bn in yearly earnings.

But bookmakers deal with a far different landscape in America than they do in the UK, where betting shops are a frequent sight.

US laws restricted betting largely to Native American lands and Nevada's Las Vegas strip up until fairly just recently.

In the popular imagination, sports betting has long been linked to a 1919 baseball World Series match-fixing scandal.

States have actually likewise been sluggish to legalise many kinds of online betting, in spite of a 2011 Justice Department viewpoint that appeared to remove barriers.

While sports betting is normally seen in its own classification, "it clearly stays to be seen whether it gets the type of momentum individuals believe it will," said Keith Miller, law professor at Drake University and co-author of a book about sports betting guideline.

David Carruthers is the former president of BetonSports, who was apprehended in the US in 2006 for running an offshore online sportsbook and served jail time.

Now a consultant, he states UK firms must approach the marketplace thoroughly, picking partners with caution and preventing mistakes that might cause regulator reaction.

"This is an opportunity for the American sports betting bettor ... I'm uncertain whether it is a chance for service," he states. "It truly depends on the outcome of [state] legislation and how business operators pursue the opportunity."

'It will be collaborations'

As legalisation starts, sports betting firms are lobbying to fend off high tax rates, in addition to requests by US sports leagues, which wish to collect a percentage of earnings as an "integrity charge".

International business deal with the included difficulty of a powerful existing video gaming market, with casino operators, state-run lottos and Native American people that are seeking to safeguard their turf.

Analysts state UK firms will require to strike collaborations, providing their expertise and technology in order to make inroads.

They point to SBTech's current announcement that it is providing technology for Kentucky Derby operator Churchill Downs as an example of the kind of offers most likely to materialise.

"It will be a win-win for everyone, however it will be collaborations and it will be driven by technology," Mr Hawkley said.

'It will just depend'

Joe Asher, primary executive at William Hill US, is clear-eyed about the truths.

The business has been investing in the US market given that 2011, when it purchased 3 US companies to develop an existence in Nevada.

William Hill now uses about 450 individuals in the US and has actually announced collaborations with casinos in Iowa and New Jersey.

It works as danger supervisor for the Delaware Lottery and has invested millions together with a regional designer in a New Jersey horse racing track.

Mr Asher stated William Hill has actually become a family name in Nevada but that's not necessarily the goal all over.

"We definitely mean to have a really substantial brand existence in New Jersey," he said. "In other states, it will simply depend on regulation and possibly who our local partner is."

"The US is going to be the most significant sports betting market worldwide," he added. "Obviously that's not going to happen on the first day."
