Shares of Reddit (RDDT) surged over 6% during Thursday’s trading session, ending a four-day decline. The rally came after Piper Sandler released data revealing robust user expansion throughout August.

Reddit, Inc., RDDT

Prior to the upward movement, RDDT traded at $156.42. The shares remain down 35.3% for the year and currently trade 42.2% beneath their 52-week peak of $270.71 reached in September 2025.

According to Piper Sandler’s examination of Reddit Ads Manager metrics, average platform users increased 8% month over month during August. This represented the year’s most significant monthly expansion and reversed July’s 2% contraction.

The year-over-year audience metric climbed to 18% in August, representing an uptick from the 12.8% recorded during July.

Global Markets Fuel User Expansion

Expansion in international markets provided the primary catalyst. According to Piper Sandler’s research, global user growth reached 29.3% year over year in August, accelerating significantly from July’s 19% rate.

Domestic users in the US expanded 5.2%, though American growth remained below the pace seen in international territories.

Feed-based users increased by 79 million during August. Meanwhile, conversation-focused users declined by 1 million during the same timeframe.

Reddit’s second-quarter earnings provide additional perspective. International daily active unique users climbed 28% year over year to reach 77.1 million, while US daily active uniques expanded 6% to 53.2 million. Weekly active unique users surpassed the 500 million threshold, reaching 514.6 million, representing 24% year-over-year growth.

Second-quarter revenue totaled $805 million, reflecting 61% year-over-year expansion. Revenue from international markets jumped 84% to reach $167 million.

Ad Revenue Projections Receive Upward Revision

User expansion figures carry significant implications for Reddit’s advertising operations. Expanded user bases generally translate to increased advertising inventory and enhanced revenue opportunities.

According to Piper Sandler, August advertising expenditures across its digital advertising tracking dataset exceeded projections by 60 basis points. Platforms including Netflix, Roku, YouTube and Pinterest delivered particularly strong results within that dataset.

The firm increased its third-quarter advertising spending growth forecast by 30 basis points and applied a similar upward adjustment to Reddit’s individual Q3 ad-spending growth estimate.

Notwithstanding these favorable trends, Piper identified a potential complication. Modifications to Reddit’s Ads Manager forecasting methodology are anticipated to reduce September audience-size projections by roughly 20%.

Piper emphasized that this adjustment stems from methodological recalibration rather than actual deceleration in user growth. The reset will not impact advertising auctions, campaign optimization or delivery mechanisms.

It bears mentioning that Reddit faces heightened regulatory scrutiny in European markets. The European Union recently classified Reddit under its most stringent category within the Digital Services Act framework, designating it as a Very Large Online Platform. This classification mandates adherence to enhanced anti-harm regulations and comprehensive systemic risk evaluations by December 2026, with potential penalties reaching 6% of worldwide annual revenue for non-compliance.

RDDT has experienced price movements exceeding 5% on 59 different occasions throughout the previous year, indicating Thursday’s rally, while positive, aligns with established volatility patterns for this equity.
