December is behind us which means it's time to check in on Twitter's mobile revenue, a monthly series I started back in 2019, when Twitter Blue launched.
Twitter is now X, and X has crossed a big milestone in December!

It also happens to be the most X has ever earned in a single month! And that's net revenue, which means what X gets to keep after Apple and Google take their share.
In terms of consumer spending, or gross revenue as developers see it, users gave X $11M. December is the first double-digit month for spending on X. That's a milestone.
The US continues to be X's biggest market with a 60% share of the total with no other country having a double-digit share. Japan comes close with 8% with the UK, Saudi Arabia, and Canada rounding out the top 5. Yes, Saudi Arabia.
Considering nothing major has changed with X in December, revenue growth is a good proxy for both engagement and demand - both climbing.
With an election coming, I expect this revenue to continue growing faster.
