Reddit's U.S. User Dip Sparks 21% Sell-Off: Overreaction?

Reddit (RDDT) reported second-quarter results that would make most companies envious. Revenue surged 61% year over year to $805 million, marking the eighth consecutive quarter of growth above 60%. Net income nearly tripled to $253 million, and management guided third-quarter revenue to $860-870 million, well above expectations.

Yet the stock plummeted 21% on Friday to around $141. The culprit? A seemingly small metric: U.S. daily active uniques (DAU) slipped to 53.2 million from 53.5 million in the first quarter. This marked the first quarter-over-quarter decline in the five quarters Reddit has reported this figure.

The company's global DAU grew 18% to 130.3 million, and weekly uniques crossed half a billion for the first time. Advertising revenue, the core business, grew 64% to $762 million. Free cash flow more than doubled to $261 million. But the U.S. user decline overshadowed all these wins.

Management attributed the dip to 'choppy' search referrals and low visibility into traffic, noting that logged-out U.S. users (often arriving from search) grew 10% while logged-in users grew just 1%. CEO Steve Huffman emphasized the company is 'not building for drive-by traffic,' but the market wasn't reassured.

Adding to the sting, Reddit spent $235 million buying back shares at an average price of $157.57—well above the current trading price. The buyback, intended to signal confidence, now looks poorly timed.

The U.S. market is Reddit's profit engine. It generates 79% of total revenue ($638 million) from just 41% of the global audience. U.S. average revenue per user (ARPU) is $11.85, more than five times the $2.26 from international users. An American user is simply worth far more to Reddit's advertisers.

This is why the sequential decline in U.S. DAU is so alarming. If the U.S. audience stalls, revenue growth must rely almost entirely on charging advertisers more per user. In the quarter, U.S. ARPU rose 51% while the audience grew only 6%—a clear sign that pricing power, not user growth, is driving gains.

Revenue growth is also decelerating gently, from 69% in Q1 to 61% in Q2. While still exceptional, the trend suggests the peak growth phase may be passing. The market is now questioning whether Reddit can sustain its premium valuation without user expansion.

At 33 times earnings after the drop, the stock looks cheaper, but that multiple assumes continued high growth. If U.S. user growth doesn't resume, the stock could face further de-rating. The next quarter will be critical: one more sequential decline could turn a wobble into a trend.

For investors, the takeaway is clear: Reddit's future hinges on reversing the U.S. user decline. The company's heavy reliance on search traffic, over which it has limited control, adds an element of uncertainty that the market is now pricing in.
