It's high stakes for UK companies as sports wagering starts to spread out in America.
From Tuesday, brand-new rules on betting entered into impact in Delaware, a tiny east coast state about two hours from Washington.
Neighbouring New Jersey might 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 industry sees a "when 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 at Davy.
For UK firms, which are facing debt consolidation, increased online competitors and harder rules from UK regulators, the timing is especially appropriate.
Why the gaming market faces an unsure future
How does illegal sports wagering work and what are the fears?
But the industry says relying on the US remains a risky bet, as UK companies face complicated state-by-state guideline and competitors from entrenched regional interests.
"It's something that we're actually focusing on, but similarly we don't desire to overhype it," stated James Midmer, representative at Paddy Power Betfair, which recently purchased the US dream sports betting website FanDuel.
'Take time'
The US accounted for about 23% of the world's $244bn (₤ 182bn) in video gaming revenue in 2015, according to a report by Technavio, external published in January.
Firms are intending to use more of that activity after last month's decision, which struck down a 1992 federal law that barred states beyond Nevada and a couple of others from authorising sports betting wagering.
The judgment found the law was an over-reach of federal power. But the court it did not actually legalise sports betting, leaving that concern to regional legislators.
That is anticipated to lead to substantial variation in how firms get accredited, where sports betting wagering can occur, and which events are open to speculation - with big ramifications for the size of the market.
Potential revenue varieties from $4.2 bn to practically $20bn each year depending on factors like the number of states transfer to legalise, Oxford Economics estimated in a 2017 research study for the American Gaming Association.
"There was a great deal of 'this is going to be substantial'", stated Will Hawkley, London-based head of leisure for specialists KPMG.
Now, he said: "I think a lot 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 time'."
'Remains to be seen"
Chris Grove, managing director at Eilers & Krejcik Gaming, forecasts that 32 states will legalise sports betting in some form by 2023, creating a market with about $6bn in yearly profits.
But bookmakers deal with a far various landscape in America than they do in the UK, where wagering stores are a frequent sight.
US laws minimal gaming mostly to Native American lands and Nevada's Las Vegas strip till relatively recently.
In the popular creativity, sports wagering has actually long been connected to a 1919 baseball World Series match-fixing scandal.
States have actually also been sluggish to legalise numerous forms of online gambling, regardless of a 2011 Justice Department viewpoint that appeared to get rid of obstacles.
While sports betting wagering is normally seen in its own category, "it clearly stays to be seen whether it gets the kind of momentum people think it will," stated Keith Miller, law teacher at Drake University and co-author of a book about sports betting wagering policy.
David Carruthers is the previous primary executive of BetonSports, who was jailed in the US in 2006 for running an offshore online sportsbook and served prison time.
Now a specialist, he states UK companies need to approach the marketplace thoroughly, selecting partners with care and avoiding errors that could lead to regulator reaction.
"This is a chance for the American sports betting bettor ... I'm unsure whether it is a chance for service," he states. "It actually is reliant on the result of [state] legislation and how business operators pursue the chance."
'It will be partnerships'
As legalisation starts, sports betting wagering firms are lobbying to fend off high tax rates, in addition to demands by US sports leagues, which wish to gather a percentage of profits as an "integrity fee".
International business deal with the included challenge of a powerful existing video gaming market, with gambling establishment operators, state-run lottery games and Native American people that are looking for to safeguard their turf.
Analysts state UK firms will need to strike collaborations, using their knowledge and technology in order to make inroads.
They point to SBTech's recent announcement that it is supplying innovation for Kentucky Derby operator Churchill Downs as an example of the kind of deals most likely to materialise.
"It will be a win-win for everybody, however it will be collaborations and it will be driven by innovation," Mr Hawkley said.
'It will simply depend'
Joe Asher, primary executive at William Hill US, is clear-eyed about the realities.
The company has actually been investing in the US market given that 2011, when it bought three US firms to establish a presence in Nevada.
William Hill now utilizes about 450 people in the US and has actually revealed partnerships with casinos in Iowa and New Jersey.
It works as threat manager for the Delaware Lottery and has invested millions together with a regional developer in a New Jersey horse racing track.
Mr Asher stated William Hill has become a home name in Nevada but that's not necessarily the objective everywhere.
"We definitely plan to have an extremely substantial brand presence in New Jersey," he said. "In other states, it will simply depend upon policy and possibly who our local partner is."
"The US is going to be the biggest sports betting wagering market worldwide," he included. "Obviously that's not going to happen on day one."
