Roblox Corporation (NYSE:RBLX) shares fell 2.5% on Monday after analysts raised fresh concerns about a recent pullback in user activity over the weekend.
According to JPMorgan analyst Cory Carpenter, the platform’s peak concurrent users (CCUs) dropped to about 23 million over the weekend, down from roughly 26 million a week earlier. That marked the weakest Saturday peak since early June.
While the game Escape Tsunami continued to add players, growing from around 3–4 million to roughly 5 million users, its momentum lagged behind that of an earlier viral title, Plants Vs. Brainrots. The gains were more than offset by a sharp decline of about 3 million CCUs in Steal a Brainrot.
Data cited by Wolfe Research showed total CCUs of approximately 22.8 million, representing a 10.6% drop from the prior week’s peak. Wolfe also noted that first-quarter-to-date average CCUs stood at 16.9 million, with growth slowing to 71% year over year, compared with about 18 million and faster growth in the previous quarter-to-date period.
Engagement during weekdays appeared more stable. Excluding a boost linked to the Martin Luther King Jr. holiday, non-peak usage was largely flat week over week, suggesting that a lighter weekend event schedule — rather than age verification changes — may have driven the drop in weekend traffic.
Several well-known Roblox experiences also showed weakening engagement. Trailing seven-day average visits for 99 Nights in the Forest fell 7.6% week over week and nearly 40% compared with three weeks earlier. Brookhaven RP recorded a 7.3% weekly decline, while Fish It! saw a steeper drop of 19.1%.
The slowdown in year-over-year engagement follows a brief period of stabilization last week, adding to investor unease about whether Roblox’s growth momentum may be starting to fade.
