Reddit Surges 50% in a Month: Is the Stock Still Worth Buying?

Reddit (RDDT) shares have surged 49.6% in the past month, driven by strong Q2 2025 results that saw EPS of $0.45 and revenue of $499.63 million, up 77.9% year-over-year, significantly beating consensus estimates. The company provided robust Q3 guidance, projecting revenues between $535 million and $545 million, reflecting continued momentum from expanded advertising offerings, growing data licensing revenue from its unique content for AI training, and accelerating international user growth, despite the stock currently trading at a premium valuation relative to peers.

Analysis

Reddit (RDDT) has demonstrated significant fundamental and market momentum, reflected in its 49.6% share price increase over the past month. This surge is directly attributable to a robust second-quarter 2025 performance, where revenues grew 77.9% year-over-year to $499.63 million and earnings per share reached $0.45, substantially beating consensus estimates and reversing a loss from the prior year. Growth is fueled by two primary vectors: an 84% YoY increase in advertising revenue driven by new performance marketing tools, and a nascent, high-potential data licensing business leveraging its vast content archive for AI training. Furthermore, the company is successfully expanding its user base globally, with international daily active uniques (DAUq) growing at 32% YoY, nearly triple the domestic rate. While the Q3 2025 revenue guidance of $535-$545 million projects continued strong growth of 54-56%, it falls slightly below the current consensus estimate of $549.59 million. The stock's valuation is a key consideration, as it trades at a forward P/S multiple of 16.5x, a significant premium to both its industry (5.58x) and peers such as Meta (8.75x) and Alphabet (6.69x). This premium is supported by a bullish technical posture, with the stock trading above its 50-day and 200-day moving averages.

Key Decisions for Investors

• Investors should recognize that Reddit's strong growth narrative, powered by accelerating advertising efficacy and a unique AI data-licensing angle, provides fundamental support for its recent stock outperformance.
• The stock's premium valuation at a 16.5x forward P/S ratio presents a significant risk, particularly as Q3 revenue guidance, while strong, tracks slightly below the current analyst consensus, making the stock vulnerable to any execution shortfalls.
• Closely monitor international user growth and the revenue contribution from data licensing in coming quarters, as these are the key catalysts cited to justify the stock's elevated multiple relative to its peers.
