The deal, announced on Monday by Sony Interactive Entertainment Chief Executive Officer Jim Ryan, comes after Reuters reported last month that Discord had ended sale talks with Microsoft Corp to focus on expanding its business as a standalone company.
Discord allows public and private groups to gather and chat by text, audio and video. It initially became popular among gamers and streamers, but is now used by communities ranging from sports fans and music groups to cryptocurrency investors.
Sony and Discord did not disclose the value of the investment.
Discord has over 140 million monthly users and its business model relies on a premium subscription service. In December, the company raised $100 million in a private funding round that valued it at $7 billion.
