Summary

Reddit Overhauls Licensing

Reddit is seeking to replace its $60 million-per-year flat Google licensing fee with a usage-based model as the renewal approaches.
The company says AI-generated search overviews made Q2 2026 referrals “choppy,” blaming Google’s Gemini summaries for reduced traffic.
Logged-in daily active uniques rose only 1% YoY while logged-out users grew markedly faster, reshaping its 130 million-user base.
Reddit will stop reporting separate logged-in versus logged-out metrics, removing a key transparency tool for investors.

History

Historical Context

When Google went public on August 19, 2004, it sold 19,605,052 shares at $85 each, raising $1.67 billion and creating a market value above $23 billion. Reddit’s planned S&P 500 entry in 2026 follows the same trajectory, expecting large passive inflows as investors chase index-eligible tech stocks. By 2014 Google’s market cap had risen to roughly $397 billion, illustrating how early index inclusion can amplify a tech firm’s valuation.
