He points to Macau’s Cotai Strip and Singapore’s Marina Bay Sands and Resorts World Sentosa as examples of how regulatory discipline can coexist with considerable freedom for developers to innovate. “At its core, Japan’s policies need to be pragmatic and allow for developments to succeed – not constrain them to the point that they risk failure.”

When asked which operator will be willing to take the risk and ultimately win Japan’s next “licence lottery”, Klebanow contends that it depends on how restrictive – or attainable – the regulations and requirements imposed by the government will be.

“If policymakers once again impose onerous policies that limit a property’s profit potential, then most developers will not take the risk of investing upwards of $10 billion in an IR development,” says Klebanow.

Based on its projections, EKG sees the overall sports wagering industry growing 8% year-over-year, outpacing the current baseline growth rate of 5% (a figure that strips out temporary boosts from the 2026 World Cup).

It has been a challenging few years for Entain, having cycled through four CEOs in short succession. In November 2023 Entain agreed to pay a financial penalty totalling £585 million, plus a £20 million charitable donation and £10 million in Crown Prosecution Service (CPS) and HMRC costs. This related to a bribery case initiated by the CPS into the company’s historic operations in Turkey.

Troubles continued as it faced declining growth within its digital business. Reports of failed integrations amid a frenzy of acquisitions further dampened Entain’s reputation and the operator subsequently committed to a major turnaround effort to cut costs and return its digital business to growth.

Efforts to update its legacy tech were also set in motion, and short-lived CEO Gavin Isaacs told iGB at ICE in January 2025 that his biggest challenge in the role was to modernise its core platform.
