Blockchain-based fantasy soccer game Sorare has raised $680 million in a funding round led by SoftBank, with players including ex-England international Rio Ferdinand and Spain's Gerard Pique also investing, the company said on Tuesday. Paris-based Sorare said the investment valued the company at $4.3 billion. Founded in 2018, Sorare is an online game where players buy officially licensed cards representing soccer players and build teams which play against each other, with the outcome based on the players' performance in real-life games.
