Reddit Has Been One of the Worst Stocks in the S&P 500. Here's Why It's a Buy.

The market is likely over-penalizing the stock for being a "story" name and underweighting how quickly a niche ad platform can compound once it proves repeatable inventory demand. The key mechanism is not user growth alone; it is whether higher-intent engagement can sustain above-market ARPU expansion without forcing ad load to levels that damage retention. If that balance holds, Reddit can keep taking budget from lower-efficiency social and entertainment inventory, but that benefit is most visible to performance advertisers first, then broader brand budgets.

The consensus risk is that investors are extrapolating percentage growth without anchoring on scale and quality. U.S. monetization is the most valuable piece of the mix, so any softening in domestic traffic acquisition or search-driven referral quality would hit both revenue and the multiple at the same time. By contrast, international expansion is a slower-burning option: it adds users, but unless monetization per user converges meaningfully, it can dilute near-term revenue quality even as headline growth stays strong.

Over the next 1-3 months, the stock likely trades on the next earnings guide and any commentary around traffic stability; that is the first falsifier if U.S. user growth or ARPU decelerates. Over 6-18 months, the structural debate is whether Reddit becomes a durable ad platform or remains a high-beta beneficiary of a favorable ad cycle. The most important contrarian point is that buybacks and AI-licensing headlines are not substitutes for ad-cycle durability; if those ancillary streams prove lumpy, the multiple can compress quickly even with good reported growth.
