Nextdoor Forecasts Fourth-Quarter Revenue of $78M to $80M

Nextdoor issued a fourth-quarter revenue forecast of $78 million to $80 million on November 5, after reporting third-quarter revenue that rose 14% year over year to $78.8 million. The company also projects Platform weekly active users will stay flat sequentially in the fourth quarter.

Why it matters

The forecast offers a read on growth at a platform whose revenue comes almost entirely from advertising, and the flat user outlook signals that seasonal patterns are tempering expansion. For U.S. advertisers and investors, the guidance points to a steady but moderating growth trajectory.

Nextdoor reported third-quarter Platform weekly active users of 24.5 million, up from 21.6 million a year earlier, and third-quarter adjusted EBITDA of $10.3 million versus $4.4 million. Its fourth-quarter outlook of $10 million to $11 million in adjusted EBITDA is not yet tested against actual results, and the company did not detail the seasonal factors behind its flat user projection.

The players

Nextdoor

Nextdoor is a neighborhood-focused social networking platform whose revenue is derived almost entirely from advertising.

The details

Nextdoor, which counts a user when they open its app or sign in to its website at least once during a seven-day period, issued its forecast after reporting results for the quarter ended September 30. The company expects full-year 2026 revenue of $293 million to $295 million and adjusted EBITDA of $30 million to $31 million.

Market Dynamics

Nextdoor's guidance continues the pattern of its reported third-quarter growth, with revenue up 14% year over year and adjusted EBITDA more than doubling from $4.4 million to $10.3 million. The flat sequential user outlook, however, marks a departure from that expansion and suggests the company is entering a period of slower audience growth.

For advertisers, Nextdoor's flat user forecast means the platform's audience reach is not expected to expand in the fourth quarter, which may affect how budgets are allocated. Users and small businesses relying on the platform for local visibility will see a service that is growing more slowly in active audience terms.

The takeaway

Growth at mature digital advertising platforms increasingly depends on keeping existing users active rather than adding new ones, a dynamic Nextdoor's flat user outlook makes visible. Readers tracking the company should watch whether profitability gains hold even as audience expansion slows.
