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

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

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

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

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

For UK companies, which are grappling with combination, increased online competition and harder guidelines from UK regulators, the timing is especially suitable.

Why the gambling market faces an unpredictable future

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

But the industry says relying on the US remains a dangerous bet, as UK business deal with complex state-by-state regulation and competitors from established regional interests.

"It's something that we're actually concentrating on, however similarly we do not desire to overhype it," stated James Midmer, representative 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 in 2015, according to a report by Technavio, external published in January.

Firms are wishing to use more of that activity after last month's decision, which overruled a 1992 federal law that disallowed states outside of Nevada and a few others from authorising sports betting wagering.

The ruling discovered the law was an over-reach of federal power. But the court it did not in fact legalise sports betting, leaving that question to local legislators.

That is expected to lead to considerable variation in how companies get accredited, where sports betting can happen, and which events are open to speculation - with big ramifications for the size of the marketplace.

Potential profits ranges from $4.2 bn to practically $20bn every year depending on factors like the number of states relocate to legalise, Oxford Economics approximated in a 2017 study for the American Gaming Association.

"There was a lot of 'this is going to be substantial'", said Will Hawkley, London-based head of leisure for consultants KPMG.

Now, he said: "I think the majority of people ... are looking at this as, 'it's a chance however it's not going to be $20bn and it's going to be state by state and it's going to take some time'."

'Remains to be seen"

Chris Grove, managing 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 annual earnings.

But bookmakers face a far various landscape in America than they do in the UK, where betting stores are a regular sight.

US laws minimal gambling largely to Native American lands and Nevada's Las Vegas strip up until relatively just recently.

In the popular creativity, sports wagering has long been connected to a 1919 baseball World Series match-fixing scandal.

States have likewise been sluggish to legalise numerous types of online betting, regardless of a 2011 Justice Department opinion that appeared to eliminate barriers.

While sports wagering is generally viewed in its own classification, "it clearly stays to be seen whether it gets the type of momentum people 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 jailed in the US in 2006 for running an overseas online sportsbook and served jail time.

Now a specialist, he states UK firms must approach the market carefully, choosing partners with care and preventing errors that might cause regulator reaction.

"This is an opportunity for the American sports betting gambler ... I'm unsure whether it is an opportunity for company," he says. "It really is dependent on the result of [state] legislation and how business operators pursue the chance."

'It will be collaborations'

As legalisation begins, sports wagering firms are lobbying to fend off high tax rates, in addition to requests by US sports betting leagues, which wish to gather a portion of income as an "integrity cost".

International companies deal with the added difficulty of a powerful existing gaming market, with gambling establishment operators, state-run lottery games and Native American tribes that are looking for to safeguard their grass.

Analysts state UK firms will require to strike partnerships, offering their know-how and technology in order to make inroads.

They indicate SBTech's current announcement that it is offering innovation for Kentucky Derby operator Churchill Downs as an example of the sort of deals likely to materialise.

"It will be a win-win for everybody, however it will be partnerships 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 company has actually been purchasing the US market considering that 2011, when it purchased 3 US companies to develop a presence in Nevada.

William Hill now employs about 450 people in the US and has revealed collaborations with gambling establishments in Iowa and New Jersey.

It works as threat manager for the Delaware Lottery and has actually invested millions along with a local designer in a New Jersey horse racing track.

Mr Asher said William Hill has actually become a family name in Nevada however that's not necessarily the objective all over.

"We definitely intend to have a very significant brand name presence in New Jersey," he said. "In other states, it will just depend on guideline and possibly who our regional partner is."

"The US is going to be the biggest sports wagering market on the planet," he included. "Obviously that's not going to happen on day one."
