Because Reddit ads appear inside community conversations rather than a curated feed, advertisers have long worried about placement next to misinformation, hate, or explicit content — driving a 2024-2025 scramble for third-party brand-safety controls.
Across 2025, CEO Steve Huffman repeatedly exercised options and sold Reddit stock under a pre-arranged plan, converting the equity that had drawn IPO-era criticism into millions in realized gains.
Investors filed a securities class action alleging Reddit misled the market about how Google's AI search features were eroding its user traffic, after the stock fell sharply in May 2025; the case is pending in the Northern District of California.
