Another bettor noted that gambling debts fractured personal relationships: “Sports betting ruined my six years of friendship because I couldn’t pay back the borrowed loan from my friend. He stopped talking to me.”

Americans wagered nearly $167 billion on sports in 2025 through regulated sportsbooks, an 11% increase year-over-year, according to data from the American Gaming Association (AGA).

They cannot target content to individuals under 18 or territories where gambling is not regulated.

To obtain Meta’s approval, the company needs to fill out a form and attach documents proving its operating licence. This same form includes a contract, in the form of an “I accept the terms and conditions” button. In it, the advertiser releases Meta from liability for any violations of the content, including legal or administrative proceedings.

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.

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.
