Dazn Group Ltd., the sports-streaming service backed by billionaire Len Blavatnik, has revived talks to raise new funding after spending heavily on its global expansion, people with knowledge of the matter said.

The U.K.-based company is speaking with advisers about options including a stock market listing or divestment of assets, according to the people, who asked not to be identified because the information is private. It is seeking to raise as much as $1 billion (?106 billion), one of the people said.

Dazn is in the early stages of considering an initial public offering, the people said. It’s also held talks about going public through a deal with a so-called special purpose acquisition company, or SPAC, and has discussed selling a stake in its Japanese business, one of the people said.
