The Norway sovereign wealth fund, the world’s largest, will probe its gambling and cryptocurrency shareholdings over ethics concerns in 2025.

The ethics watchdog of the $1.8tn Government Pension Fund of Norway will investigate gambling and cryptocurrency businesses for potential breaches, according to a document seen by Reuters.

The document reportedly said: “The Council on Ethics in 2025 will take a closer look at companies involved in cryptocurrencies and gambling/casino, where there is a significant risk of money laundering.”
