OTX Brainrot Index

Total concurrent players across the brainrot ecosystem on Fortnite.

Methodology

Sum of latest daily peak CCU across Fortnite islands whose title self-identifies as brainrot (ILIKE %brainrot%). "Brainrot" is an off-taxonomy community label, not an official Fortnite tag. IMPORTANT — this is a coverage-weighted composite, not a fixed-basket index: the constituent set is every matching island we track on that day, so the series moves when our coverage changes, not only when player behaviour does. Day-over-day moves are therefore not directly comparable to a rebalanced index. A fixed-basket definition with documented rebalancing is planned. Platform-owned modes are excluded. Append-only: each day is published once and never revised.

Published values are immutable — an append-only history. See the full methodology + accuracy page.
