Overview
DA Davidson's monitoring of Duolingo Inc's (NASDAQ: DUOL) user activity shows headline improvement in second-quarter daily active user growth, but the firm is flagging concerns about whether that improvement can be sustained into the back half of the year.
According to Wyatt Swanson at DA Davidson, the firm's panel-derived estimate has 2Q'26 DAUs tracking at approximately 21.7% year-over-year growth. That figure is ahead of the +20.4% consensus and is roughly 200 basis points higher than Duolingo's own guidance, based on the June 29 update from the analyst.
Near-term momentum easing
Even with the favorable headline comparison, DA Davidson notes a notable tempering of short-term momentum. Week-over-week DAU growth decelerated for three straight weeks in June and then flattened in the fourth week of the month, following a +0.6% reading the week prior. That pattern has prompted DA Davidson to question the persistence of the app's engagement gains.
How the panel works and its limits
DA Davidson relies on a proprietary panel of more than 170,000 existing Duolingo accounts to estimate DAU trends ahead of reported results. Within that dataset, June DAUs were tracking up +5.7% month-over-month, a rise from the +5.0% reading recorded two weeks earlier. Those month-over-month dynamics feed into the firm's consolidated 2Q'26 DAU estimate of 21.7% Y/Y.
Swanson cautions, however, that the panel has structural limitations: it is underweight in Asia-Pacific representation. The firm therefore believes its panel likely understates actual DAU growth, and that there is upside to the 21.7% estimate. For context, DA Davidson's final panel estimate for 1Q'26 was 19.5% Y/Y compared with Duolingo's reported 21.2% - a shortfall that fits within the panel's historical tendency to understate growth by roughly 100-200 basis points.
Campaign-driven engagement and monetization timing
DA Davidson attributes much of the early-June surge in engagement to Duolingo's streak revival campaign, which the firm views as a catalyst for re-engaging highly active users. Yet the analyst also points out that by late June the campaign's lift had dissipated, even though the promotion remained active.
The monetization implications complicate the picture. The users who rejoined in response to the streak revival were likely on a one-month free trial, meaning any paid conversions tied to that cohort would appear in third-quarter bookings rather than in the current quarter. Swanson expresses skepticism that the event alone will produce sustained bookings growth, saying in his note that he is not sure the streak revival will translate into durable paid conversions. He further argues that more meaningful monetization changes will likely be required for DAUs and bookings to expand in tandem.
3Q math presents a higher bar
Looking ahead to the third quarter, consensus estimates sit at 60.7 million DAUs, representing +20.2% year-over-year growth. Swanson outlines the arithmetic needed for Duolingo to meet consensus under different scenarios. He calculates that if Duolingo outperforms its own 3Q guide by 170 basis points, that outcome would equate to roughly 58.0 million DAUs. Reaching consensus would then require adding about 2.7 million net DAUs quarter-over-quarter.
DA Davidson places that figure in context with Duolingo's historical performance: the three-year average for 3Q net adds is 2.9 million, implying the consensus target is achievable but leaves little margin for surprise. By contrast, replicating the scale of the 2Q beat that DA Davidson currently models would demand 3.4 to 3.5 million net DAU adds in 3Q - a pace that would constitute the largest third-quarter net add in Duolingo's history. The prior 3Q record was 3.1 million net adds in 3Q'24.
Valuation and rating
Against these dynamics, DA Davidson maintained its Neutral rating on Duolingo and kept its $120 price target. The firm notes that the $120 level implies 15x its 2026 EBITDA estimate and 13x its 2027 EBITDA estimate. The rating reflects a view that while near-term DAU outperformance is plausible, the prerequisites for a durable re-rating have not yet been satisfied.
What investors should watch
DA Davidson advises that investors looking ahead to Duolingo's second-quarter results should not focus solely on the headline DAU figure. Management commentary on third-quarter engagement and any evidence that the streak revival campaign has produced meaningful conversions to paid subscriptions will be crucial. How the company describes the durability of engagement and the pathway to bookings growth will be central in assessing whether the 2H'26 growth story can hold.
