Duolingo has clarified that preliminary internal data regarding user growth was inadvertently displayed during an investor meeting, emphasizing that the figures have not been validated. The company stated it does not intend to provide additional or updated guidance following the incident.
On August 18, 2026, during an in-person meeting with certain investors at Duolingo’s offices, a screen in the meeting room inadvertently displayed information indicating that the daily active user (DAU) growth rate on August 17, 2026, was estimated to be 27.4% relative to the comparable day of the prior year. The disclosure noted that there had been similar estimated growth rates for the previous days in August.
The company explicitly stated that it has not completed its normal review and validation of this preliminary internal data. Consequently, Duolingo warned that this information should not be read as indicative of the company's expected results for Q3 2026 or any future period.
Duolingo’s most recent guidance remains as set forth in its Q2 2026 shareholder letter dated August 5, 2026. The company confirmed it is not providing any, and does not intend to provide, additional or updated guidance at this time.
What the Numbers Show
The disclosed figure of 27.4% represents a year-over-year estimate for a single day (August 17, 2026), rather than a full-quarter metric. The company’s refusal to validate or update guidance suggests a strict adherence to its reporting standards, distinguishing between preliminary internal estimates and official financial disclosures.
