The [ACX 2024 Prediction Contest](https://www.metaculus.com/tournament/ACX2024/) is open! **Forecast before January 22nd** to participate! \$2.5k in prizes!

Scott Alexander's annual tradition of predicting the upcoming year has evolved into a full forecasting contest. For 2024, he invited Metaculus to host the competition. Kick off the new year forecasting on questions like:

* [Will an AI win a coding contest on Codeforces in 2024?](https://www.metaculus.com/questions/20759/ai-wins-coding-competition-in-2024/)
* [Which party will win the 2024 US presidential election?](https://www.metaculus.com/questions/20772/party-winning-the-presidency-in-2024/)
* [Will Ali Khamenei cease to be supreme leader of Iran in 2024?](https://www.metaculus.com/questions/20783/khamenei-out-as-leader-of-iran-in-2024/)
* [Will SpaceX's Starship reach orbit in 2024?](https://www.metaculus.com/questions/20775/starship-reaches-orbit-in-2024/)

We will take a snapshot of forecasters' predictions as of January 21st, 11:59 PM PT, and these will determine the contest winners. Learn more and get started on the contest page [here](https://www.metaculus.com/tournament/ACX2024/?has_group=false\&project=2844\&order_by=-activity).
