Reddit’s ad engine finds a higher gear

An 84% surge in quarterly ad revenue puts Reddit on a faster track than its peer set. For CMOs, the lesson is: intent-rich conversations convert when you meet them in-context.

---

Reddit’s advertising revenue jumped 84% year on year in Q2 2025 to roughly $465m, helping total revenue reach $500m and lifting margins across the board.

In a social market still wobbling between cookie-loss and new AI surfaces, Reddit has become the outlier: faster growth, sharper monetisation, and a bolder bet on search. That combination is resetting expectations for what “emerging” platforms can deliver.

How Reddit’s performance compares to other Social Networks

The standout figure is ad revenue up 84% a pace that outstrips Snap (c.4–9% revenue growth, depending on mix) and Pinterest (+17%). Even X’s projected ad recovery mid-teens growth this year from a lower base doesn’t get close. In aggregate, Reddit looks like the fastest-growing major social platform on the ad line, albeit from a smaller base than Snap or Pinterest. For marketers, that differential growth is a signal to re-weight test budgets, not a cue to abandon incumbents.

WARC’s datapoint puts this in wider context: Reddit crossed the $1bn ad threshold within a year (2024), a milestone that took Pinterest four years evidence that community-led intent can scale quicker than expected when the product and demand line up.

Why Reddit is accelerating

Three levers explain the step-change:

1. In-context performance formats. Reddit rolled out Shopping Ads and dynamic product ads (DPA) to general availability, integrated planning/creation/measurement with Smartly, and is seeing early traction: 2× ROAS on Shopping Ads (vs. standard conversion campaigns) and a 4× increase in hosted product catalogues. That is a practical, bottom-funnel story, not just brand adjacency.

2. “Conversation Summary” add-ons. AI surfaces positive, trusted comments right beneath the ad, social proof at the point of decision, which Reddit says is lifting CTRs versus standard image ads. This is classic Reddit: use the grain of the platform (human conversation) to de-risk a click.

3. Search as a strategy, not a feature. Reddit management is “concentrating resources” to make Reddit a go-to search engine, leaning into the reality that many product queries now begin with “what does Reddit say?”. That bridges discovery and purchase intent without third-party cookies.

The financials back up the product thesis: ARPU rose 47% to $4.53, gross margin reached 90.8%, and guidance points to another strong quarter ($535–$545m revenue; $185–$195m adjusted EBITDA). Growth is not yet purely seasonal; momentum is coming from product-market fit.

What this means for media buyers

A few takeaways:

• Intent > identity. In a world with fewer identifiers, Reddit’s advantage is declared intent inside communities. A camera brand doesn’t need third-party data if r/photography is debating mid-range mirrorless bodies this week. The adjacency is the targeting.

• Proof at the point of impression. Conversation add-ons are the kind of lightweight, verifiable social proof that can shave friction on mobile. Treat them as conversion boosters, not brand flourishes.

• Retail media logic, social surface. Shopping Ads and DPA shift Reddit closer to retail media outcomes without owning a checkout. If your product feed and catalogue hygiene are weak, fix that first—then test against your best-performing social DR placements.

• Budget physics. If you’re overweight open-auction social with rising CPMs and volatile signal quality allocate a small but material slice (say 5–10%) to Reddit performance formats for two sprints. Evaluate on incremental conversions and assisted revenue, not last-click alone.

• Search behaviours are drifting. As Reddit deepens search, paid formats that meet users at “better than Google snippet” moments will matter. Start capturing the long-tail queries your customers already paste into Reddit.

The risks worth watching

Reddit’s growth still sits on a smaller user base than the giants. Scale limitations mean you’ll hit frequency caps or subreddit saturation faster than on Meta or TikTok. Execution risk also looms: community trust requires tight moderation; any stumble hurts brand suitability. And the growth rate will normalise 84% YoY isn’t a steady-state. But the direction of travel is clear: high-intent, context-first ad products can outrun broader social averages.

A quick CMO playbook (90-day plan)

1. Stand up a product-feed test. Sync your catalogue; run DPA and Shopping Ads against two intent-heavy subreddits; benchmark ROAS vs. your best Meta DR ad set.

2. Wire in conversation proof. Add Conversation Summary to your top SKUs and write creative that invites comparison (“How do real users rate X vs Y?”).

3. Build a “Reddit search” spine. Harvest live queries from communities and your support logs; map them to landing pages; tailor copy and CTAs to how Redditors ask.

4. Measure incrementally, not just CPA. Use geo-splits or subreddit-level holdouts to isolate lift.

5. Mind the creative grain. Use authentic imagery, plain language, and credibility cues (warranty, return policy, spec sheets) over glossy lifestyle.

The bigger picture

Wall Street’s enthusiasm here isn’t just multiple expansion. It’s a read-through to where performance budgets go next: toward surfaces that mix human validation with AI-assisted discovery. Reddit is proving that if you architect for intent, you can grow faster than peers still tuning their signal pipelines. The task for marketers is to follow the attention—and the argument—into the comment thread.
