Introduction
Duolingo (NASDAQ: DUOL) has rapidly grown its user base, making Daily Active Users (DAUs) one of its most important performance indicators. TickerTrends’ KPI Tracker is a forward-looking analytics platform that uses real-time digital signals to forecast key company metrics before earnings. Each forecast is made using only the data available at the time and is never retroactively revised.
This case study highlights how TickerTrends successfully predicted Duolingo's DAUs across several quarters. In each example, TickerTrends’ KPI Tracker offered more accurate projections than consensus analyst estimates, helping investors anticipate growth or slowdowns ahead of reported results.
Methodology
All KPI forecasts from TickerTrends are built using a proprietary forecasting model that blends a curated mix of alternative data sources tracked by TickerTrends which focus on consumer social data across online venues.
We continuously evaluate and optimize our models to identify the most predictive data signals for each company or KPI. Through systematic backtesting and algorithmic feature selection, these signals are dynamically weighted and integrated into our live forecasting models.
Forecasts are always point-in-time. For each quarter, predictions are published using only the data available up to that moment. We may update forecasts on a rolling weekly basis within a quarter as new data comes in, but we never alter or overwrite previous predictions. This allows for full transparency and accountability when evaluating performance after earnings are released.
This case study focuses specifically on our publicly archived Duolingo DAU predictions compared to analyst consensus and final reported metrics. Analyst Consensus is what Factset reports for analyst KPI consensus estimates going into that specific quarter.
Our KPI Dashboard highlights what our predictions for each specified KPI metric was with the data available only at that time or before. Forecasts versus the actual report quarter are shown.
Q2 2024 – Anticipating a Breakout in User Growth
In Q2 2024, analysts expected Duolingo to continue its growth trajectory, with consensus estimates near 33.56 million DAUs. TickerTrends’ real-time signals suggested sustained user engagement and indicated a stronger quarter ahead. Our point-in-time forecast projected DAUs would reach approximately 34.36 million.
Duolingo ultimately reported 34.1 million DAUs, beating analyst consensus by a wide margin and far closer to what we expected. TickerTrends accurately captured the user growth acceleration weeks ahead of earnings and outperformed consensus estimates.
Q3 2024 – Forecasting Continued Engagement Into Fall
For Q3 2024, most analysts expected DAU growth to slow slightly, with consensus landing around 37.72 million. TickerTrends’ weekly KPI updates continued to reflect strong momentum across app usage and web traffic. Our forecast estimated Duolingo would reach roughly 37.59 million DAUs by the end of the quarter.
Duolingo reported 37.2 million DAUs, only slightly under TickerTrends’ projection but far more accurate than analysts. Our models successfully captured the continued strength in engagement that analysts overestimated.
Q4 2024 – Accurately Predicting a Slight Seasonal Dip
Heading into Q4 2024, consensus estimates were increasingly bullish, predicting Duolingo would reach 41.09 million DAUs. TickerTrends’ models picked up early signals of slowing momentum in engagement velocity. Our forecast settled around 40.54 million DAUs for the quarter.
Duolingo ultimately reported 40.5 million DAUs. While still strong year over year, this \missed analyst expectations. TickerTrends delivered a more measured and accurate forecast, capturing the weaker trend the consensus saw at the time.
Q1 2025 – Catching a Growth Re-acceleration Early
For Q1 2025, consensus estimates projected DAUs to reach approximately 46.00 million. However, TickerTrends detected a strong social resurgence in user activity across multiple channels. Our point-in-time model projected a stronger reacceleration, forecasting 47.51 million DAUs.
Duolingo ultimately reported 46.6 million DAUs for Q1 2025, once again confirming the growth pickup beyond what analysts saw. While analysts underestimated the magnitude of post-holiday engagement rebound, TickerTrends picked up on leading indicators that reflected accelerating demand.
Forecast Performance Summary
In each quarter, TickerTrends’ forecast was directionally and numerically closer to the actual DAU results than consensus. Whether calling an upside beat or identifying a slight shortfall, the model consistently outperformed analyst expectations, and the stock price reactions to each respective earnings report followed suit.
Conclusion
This case study demonstrates how TickerTrends’ KPI Tracker accurately forecasted Duolingo’s DAU growth ahead of earnings across multiple quarters. Using only real-time alternative data and point-in-time methodology, the platform consistently beat Wall Street consensus. This gave analysts valuable information to anticipate big beats while avoiding large drawdowns during weaker quarters.
By combining multiple alternative data sources into a unified forecasting engine, TickerTrends provided reliable visibility into user trends before they were publicly reported. The Duolingo case is a clear example of how digital behavior, when processed intelligently, can produce KPI forecasts that are more accurate than traditional models or analyst forecasts.
For investors and analysts focused on forward-looking metrics, TickerTrends offers a powerful tool to improve timing, expectation management, and idea generation using real consumer and product momentum data with a proven track record of being more accurate than analyst KPI estimates.
