The forecast: Following a year of somewhat stalled growth, Twitter will soar past $2 billion in US ad revenues in 2021, marking a 38.5% increase over 2020.

Dive deeper:

• With an increase in live events, sports, and product launches in 2021 over 2020, advertisers flocked to Twitter due to increased demands for advertising campaigns on the platform.
• This was big for Twitter, given that advertising will make up 89% of the platform's total revenues in 2021. We expect that figure to flutter above 91% in 2023.
• Twitter's US ad revenues make up 54.1% of its total ad revenues. That share is expected to increase to 54.8% by 2023, with US ad revenues growing at a faster rate than international ad revenues.

Looking ahead: Twitter's US ad revenues will continue their flight in the coming years, passing $3 billion in 2023.
