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

From Tuesday, new rules on wagering entered effect in Delaware, a tiny east coast state about 2 hours from Washington.

Neighbouring New Jersey might begin accepting sports 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 way for states to allow sports betting.

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

For UK firms, which are grappling with debt consolidation, increased online competitors and tougher rules from UK regulators, the timing is especially opportune.

Why the gambling industry deals with an unsure future

How does illegal sports wagering work and what are the worries?

But the market states relying on the US stays a dangerous bet, as UK companies face complex state-by-state guideline and competition from entrenched regional interests.

"It's something that we're truly focusing on, but equally we do not want to overhype it," stated James Midmer, spokesman at Paddy Power Betfair, which recently purchased the US fantasy sports site FanDuel.

'Require time'

The US accounted for about 23% of the world's $244bn (₤ 182bn) in video gaming income in 2015, according to a report by Technavio, external released in January.

Firms are hoping to take advantage of 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.

The judgment found the law was an over-reach of federal power. But the court it did not actually legalise sports wagering, leaving that concern to regional lawmakers.

That is expected to result in considerable variation in how firms get accredited, where sports wagering can happen, and which occasions are open to speculation - with huge ramifications for the size of the marketplace.

Potential earnings ranges from $4.2 bn to almost $20bn every year depending upon elements like how lots of states move to legalise, Oxford Economics estimated in a 2017 research 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 specialists KPMG.

Now, he said: "I think most individuals ... 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, managing director at Eilers & Krejcik Gaming, predicts that 32 states will legalise sports betting in some kind by 2023, creating a market with about $6bn in annual income.

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

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

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

States have also been slow to legalise numerous types of online betting, regardless of a 2011 Justice Department viewpoint that appeared to eliminate barriers.

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

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

Now a consultant, he states UK firms need to approach the marketplace thoroughly, selecting partners with care and preventing missteps that might cause regulator backlash.

"This is a chance for the American sports bettor ... I'm not exactly sure whether it is an opportunity for organization," he says. "It really is dependent on the outcome of [state] legislation and how the organization operators pursue the opportunity."

'It will be collaborations'

As legalisation begins, sports wagering companies are lobbying to fend off high tax rates, in addition to requests by US sports leagues, which desire to gather a portion of earnings as an "integrity charge".

International companies face the included obstacle of a powerful existing gaming industry, with casino operators, state-run lottos and Native American people that are looking for to safeguard their grass.

Analysts state UK firms will need to strike collaborations, using their proficiency and technology in order to make inroads.

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

"It will be a win-win for everybody, however it will be collaborations and it will be driven by technology," 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 buying the US market given that 2011, when it purchased 3 US companies to develop an existence 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 danger manager for the Delaware Lottery and has invested millions together with a local developer in a New Jersey horse racing track.

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

"We certainly mean to have a really substantial brand presence in New Jersey," he stated. "In other states, it will simply depend on guideline and possibly who our regional partner is."

"The US is going to be the most significant sports wagering market on the planet," he included. "Obviously that's not going to occur on the first day."
