trailing Instagram and Facebook. Interestingly, after Snapchat passed Instagram in early 2016 in average minutes per user, Instagram recaptured the lead mid-year and has extended it since. While the cause for the shift is not certain, the trends align with the launch of Instagram Stories (August 2016) as well as some technology challenges on the Snapchat front (Android). Regardless of the near-term lumpiness, we believe overall daily engagement puts Snapchat in a strong position to capture emerging online marketing ad budgets.

For the year, our $1.0bn revenue estimate is mostly in-line with the Street, as is our 2018 estimate at $2.1bn. We do not model positive adjusted EBITDA until 2Q19, and expect investors to focus mostly on user revenue trends.
