Clinicians who treat gambling disorders are concerned about their patients turning to prediction markets. Two gambling addicts who spoke to The Associated Press say they had relapses on prediction markets after they took legal action to protect themselves from the allure of sports betting. Their stories reflect what experts say they see with some of their clients.

For clinicians and addicts, when it comes to sports betting and prediction markets, the end result is virtually the same.
