reddit last 5 years us dau growth yoy

Reddit’s U.S. Daily Active Uniques (DAUq) underwent an aggressive boom-to-bust cycle over the last five years: surging from low-single-digit pre-IPO growth into a +51% YoY peak in Q3 2024 as Google's search algorithms heavily indexed forum discussions, before decelerating sharply through 2025 and slipping to -2% YoY in Q3 2026 as Google AI Overviews and conversational answer engines began eroding top-of-funnel search referrals.

Era 1: Steady Pre-IPO Organic Crawl (2021 – 2023)

• Growth Band: +4% to +12% YoY.
• Characteristics: Reddit was managed primarily as an English-speaking community hub. U.S. daily traffic expanded moderately from ~35M to ~44M, with logged-in and logged-out users growing at similar single-to-low-double-digit paces.

Era 2: The Google Search Arbitrage Supercycle (2024)

• Growth Band:+32% to +51% YoY.
• Characteristics: In late 2023 and early 2024, Google overhauled its ranking systems (Hidden Gems and helpful content updates) to heavily favor firsthand forum discussions on SERPs.Overnight, Reddit became visible across an estimated 42%+ of informational search queries.
• The Logged-Out Distortion: This surge was heavily skewed toward passive, logged-out web searchers (who grew +70% YoY in Q3 2024, while logged-in users grew +27%).

Era 3: The AI Search Headwind & Saturation (2025 – 2026)

• **Growth Band:**Deceleration from +18% in Q1 2025 down to -2.0% in Q3 2026.
• Characteristics:

1. Google AI Overviews / AI Mode: Search engines evolved from directing users to blue links into providing conversational synthesized summaries directly on the search results page.On the Q3 2026 earnings call, Reddit disclosed that search referrals began falling meaningfully late in the quarter, shedding over 1 million search referrals per week on average in October 2026.
2. The Resulting Asymmetry: The entirety of the U.S. contraction hit the logged-out cohort (which fell from 30.1M in Q2 2026 to 27.3M in Q3 2026). Meanwhile,U.S. Logged-In DAUq was insulated, inching up sequentially from 23.1M to 23.4M (+1.3% YoY).
