Reddit Inc Class A (RDDT) surged 6.30% to $155.66 on Thursday, driven by reports of strong August user growth. The stock opened with a 1.2% gap up and reached an intraday high of $156.88 before closing near that level. The move followed third-party data showing Reddit’s user base grew 8% month-on-month, the fastest rate of the year, with international users rising 29%. Analysts and investors interpreted the user acceleration as a sign of improving ad trends and a potential reset in audience size due to changes in Reddit’s ads manager model.

What Happened

Reddit’s stock climbed after Piper Sandler cited the fastest user growth of the year, with a 8% increase in monthly active users and a 29% jump in international users. The data, which also noted that Reddit’s new ads manager model could lead to a 20% reset in reported audience size, fueled optimism about the platform’s ability to attract advertisers. The Motley Fool highlighted Reddit’s recent profitability and expanding revenue streams as key differentiators in the tech sector. Meanwhile, the CEO emphasized growing users and improving new user retention as a primary focus for the next 12 to 18 months.

What The Data Shows

The stock opened at $148.18 and traded as low as $144.80 before rallying to a high of $156.88. Volume reached 2.8 million shares, or 0.5 times the 3-month average. Reddit’s fundamentals show a market cap of $28.7 billion, a P/E of 34.1, and trailing 12-month revenue growth of 66.6%. Recent insider transactions include sales by CEO Steve Huffman and other executives, totaling $47.7 million in the last 90 days. The stock has declined 4.5% over the past 8 sessions, from $153.00 to $146.08.

What To Watch

Reddit’s next key event is its scheduled earnings report. Investors will also monitor coverage breadth and whether the recent user growth translates into higher revenue and improved profitability.
