One concern for operators is “the short duration of licences and renewal of licences”, notes Leckert. For operators, the casino business licence is renewable every three years, while the IR development-plan authorisation runs for 10 years, in contrast to the 18-year IR licence term in the Philippines, for instance.

Limiting the duration of licence validity “puts the entire capital investment at risk”, says Klebanow. Further regulations, including limiting residents to 10 visits per month and requiring them to present a ‘My Number Card’ when gambling, further erodes project viability. “Ultimately, casino developers individually concluded that developing an IR was too risky, and they took their billions of dollars in potential capital investment and walked away,” observes Klebanow.

Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
