It's high stakes for UK firms as sports betting starts to spread in America.
From Tuesday, brand-new rules on wagering entered result in Delaware, a tiny east coast state about 2 hours from Washington.
Neighbouring New Jersey might 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 wagering.
The market sees a "once in a generation" opportunity to develop a brand-new market in sports betting-mad America, stated Dublin-based financial analyst David Jennings, who heads leisure research study at Davy.
For UK companies, which are coming to grips with consolidation, increased online competition and tougher rules from UK regulators, the timing is particularly opportune.
Why the gambling market faces an uncertain future
How does prohibited sports wagering work and what are the fears?
But the industry states counting on the US remains a dangerous bet, as UK companies deal with complicated state-by-state guideline and competition from entrenched local interests.
"It's something that we're truly concentrating on, however similarly we don't wish to overhype it," said James Midmer, spokesperson at Paddy Power Betfair, which just recently bought the US dream sports website FanDuel.
'Take some time'
The US accounted for about 23% of the world's $244bn (₤ 182bn) in video gaming earnings last year, according to a report by Technavio, external published in January.
Firms are intending to take advantage of more of that activity after last month's decision, which struck down a 1992 federal law that disallowed states outside of Nevada and a couple of others from authorising sports betting.
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 result in significant variation in how firms get accredited, where sports betting wagering can take place, and which occasions are open to speculation - with big ramifications for the size of the marketplace.
Potential profits ranges from $4.2 bn to practically $20bn yearly depending on factors like how numerous states transfer 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'", stated Will Hawkley, London-based head of leisure for specialists KPMG.
Now, he stated: "I think many people ... are taking a look 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 require time'."

'Remains to be seen"
Chris Grove, managing director at Eilers & Krejcik Gaming, forecasts that 32 states will legalise sports wagering in some kind by 2023, creating a market with about $6bn in annual revenue.
But bookies deal with a far various landscape in America than they carry out in the UK, where wagering shops are a frequent sight.
US laws limited betting mainly to Native American lands and Nevada's Las Vegas strip till fairly recently.
In the popular creativity, sports betting has long been connected to a 1919 baseball World Series match-fixing scandal.
States have likewise been slow to legalise lots of forms of online gaming, despite a 2011 Justice Department opinion that appeared to remove obstacles.
While sports betting is generally seen in its own category, "it clearly stays to be seen whether it gets the sort of momentum people believe it will," stated Keith Miller, law professor at Drake University and co-author of a book about sports betting policy.
David Carruthers is the previous president of BetonSports, who was arrested in the US in 2006 for running an offshore online sportsbook and served jail time.
Now a consultant, he states UK companies need to approach the market carefully, choosing partners with caution and avoiding errors that might lead to regulator backlash.
"This is a chance for the American sports betting bettor ... I'm not sure whether it is a chance for organization," he states. "It actually depends on the outcome of [state] legislation and how business operators pursue the opportunity."
'It will be partnerships'
As legalisation begins, sports betting firms are lobbying to ward off high tax rates, as well as demands by US sports leagues, which desire to gather a portion of income as an "stability cost".
International business deal with the added obstacle of an effective existing gaming market, with gambling establishment operators, state-run lottos and Native American tribes that are looking for to protect their grass.
Analysts say UK companies will require to strike collaborations, using their knowledge 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 most likely to materialise.
"It will be a win-win for everyone, but it will be partnerships and it will be driven by innovation," Mr Hawkley said.

'It will simply depend'
Joe Asher, chief executive at William Hill US, is clear-eyed about the truths.
The business has been purchasing the US market considering that 2011, when it purchased three US firms to develop an existence in Nevada.
William Hill now utilizes about 450 people in the US and has actually announced partnerships with casinos in Iowa and New Jersey.
It works as danger manager for the Delaware Lottery and has actually invested millions alongside a local designer in a New Jersey horse racing track.
Mr Asher stated William Hill has actually ended up being a family name in Nevada however that's not necessarily the goal all over.
"We certainly intend to have a very significant brand name existence in New Jersey," he stated. "In other states, it will simply depend on policy and potentially who our local partner is."
"The US is going to be the biggest sports wagering market worldwide," he included. "Obviously that's not going to occur on the first day."
