Author summarizes Reddit's Q4 2025 conference call, highlighting positive ad trends but reinforcing a cautious thesis on Reddit's capped ARPU, potential dilution, and reduced disclosure.
RDDT — AVOID Author argues Reddit's ad monetization is structurally capped because management positions the company as competitive with tier-2 peers (SNAP/Pinterest/Twitter) but behind tier-1 peers (Google/META), reinforcing his thesis that Reddit will only reach a small part of ARPU. He notes management is using machine learning to improve ad performance but does not see that closing the gap to tier-1 monetization. No specific risk to this bearish thesis is stated.
This reinforces my thesis that Reddit will only reach a small part of ARPU.
RDDT — AVOID Author calculates that stock-based compensation at high teens of revenue could produce roughly 1.9% dilution in 2026 if all are RSUs, or closer to 3% if SBC includes more options. He notes buybacks are the lowest priority in capital deployment, with management preferring reinvestment and M&A. This creates a shareholder dilution risk.
If SBC comprises more share options than RSU, dilution rate will be higher than 1.9%, possibly closer to 3%.
RDDT — WATCH Author notes that total active advertiser count grew 75% year-over-year, but worries this may reflect more first-time advertisers trying Reddit rather than proven long-term retention. He explicitly says this ambiguity warrants caution because ad revenue growth could be less durable if advertisers do not stay. No specific risk to this caution is stated.
Negative is Reddit is growing ad revenue from more advertisers trying out the platform for first time, but not proving to retain them in the long term. I m think the latter warrants caution.
RDDT — WATCH Author flags that management did not discuss user growth and plans to stop reporting logged-out and logged-in users separately, which he views as a concern. This reduces visibility into Reddit's engagement trends and could mask slowing DAU growth. No specific risk to this concern is stated.
Management did not touch on user growth, which is a concern because at the same time, management is also going to stop reporting logged out and logged in users separately.
RDDT — WATCH Author notes Reddit is expanding ad revenue beyond finance, legal, communication and tech into retail and pharma, as management promised at IPO, which could broaden its advertiser base. This positive insight from the Q4 2025 call suggests execution on ad vertical diversification. No specific risk to this positive view is stated.
Reddit ad strength was previously mainly in Finance, Legal, Communication and Tech. Now Reddit is successfully gaining Retail + Pharma ads, just as it said it would during its IPO.
