The Beat

Reddit crushed third-quarter expectations.

Revenue surged 68% year-over-year to $585 million, easily beating the LSEG estimate of $546 million. Earnings per share hit 80 cents versus the 51-cent estimate - a massive beat.

The stock responded accordingly, jumping more than 14% Friday.

Reddit also issued strong Q4 guidance, projecting revenue between $655-$665 million. That tops Wall Street's $638 million forecast.

The Advertising Story

Reddit's advertising business is taking off.

Nine of the company's top 15 advertiser verticals grew more than 50%. The number of active advertisers jumped 75% year-over-year in Q3.

Morgan Stanley analyst Brian Nowak wrote that results "speak to the company's continued progress across its ad and platform initiatives." He sees "a long runway for growth across both active advertisers as well as greater penetration within existing advertisers."

Reddit has been investing heavily in automation to improve return on ad spending. Those investments appear to be paying off as advertisers see better results and increase spending.

User Growth Beats

Daily active users jumped 19% from last year to 116 million, topping Wall Street's 114 million estimate.

Reddit is pulling more people from Google searches and converting them to logged-in accounts. That matters because the company makes more money from logged-in users than anonymous visitors.

Globally, logged-in users grew 14% to 50.2 million. Daily active unique users rose 7% to 23.1 million, though that lagged the 12% growth seen in Q2.

The AI Question

Reddit CEO Steve Huffman addressed concerns about AI chat apps like ChatGPT and Google's AI Overview potentially impacting user growth.

"They're not a major traffic driver today," Huffman said on the earnings call. "But I think there's plenty of opportunity there as we continue to work together."

Reddit has data licensing partnerships with both Google and OpenAI. Those deals generated $36 million in "other revenues" during Q3, up 7% from last year.

The company seems unconcerned about AI chatbots cannibalizing traffic. Instead, Reddit views partnerships with AI companies as opportunities.

Why This Matters

Reddit's strong results validate its business model transformation.

The company went public in March 2024 amid questions about whether it could monetize its massive user base. These Q3 results show Reddit is successfully turning users into advertising revenue.

The 68% revenue growth is impressive for a company Reddit's size. The fact that it's beating estimates while also guiding higher suggests momentum is accelerating, not slowing.

Advertiser growth of 75% year-over-year shows businesses are discovering Reddit's value. The platform's unique community-driven content creates engaged audiences that advertisers want to reach.

The Bottom Line

Reddit delivered exactly what investors wanted to see - strong revenue growth, user growth, and positive guidance.

The 14% stock pop reflects relief that Reddit can maintain momentum. The company proved it's not a one-hit wonder - Q3 built on strong Q2 results.

The advertising business is clearly working. When nine of your top 15 verticals grow over 50%, you're doing something right. The 75% jump in active advertisers shows Reddit is expanding beyond early adopters to mainstream advertising budgets.

User growth topping estimates matters because it's the foundation for future revenue. More users, especially logged-in users, means more inventory to sell to advertisers.

The AI partnerships generating $36 million might be small today, but they represent upside potential. If AI companies increasingly use Reddit's data to train models, that revenue stream could grow significantly.

Huffman's dismissal of AI chat concerns suggests Reddit isn't worried about being disrupted. The company seems confident its community-driven model creates sticky engagement that AI summaries can't replace.

For investors who bought Reddit's IPO or shortly after, this validates the thesis. The company is executing on its advertising strategy while growing users. That's the recipe for a successful social media platform.

The strong Q4 guidance showing continued momentum removes concern about Q3 being a fluke. Reddit appears to have genuinely found its groove as a public company.
