On Feb 23, 2022 peace in Europe was shattered when Russia began a full scale invasion of Ukraine. At this critical time, trustworthy forecasts are greatly needed to help both the public and policymakers track and understand the evolving conflict and its implications.

Forecasts in this series will be updated over the coming days and weeks, and will cover a range of topics:

• Likelihood of invasion into new territories
• Troop movements
• Conflict casualties
• Social and political implications
• Energy infrastructure
• Sanctions and other policy responses
• US-Russia diplomacy
• Chinese response
• Economic impact

In the runup to the invasion, the Metaculus Community rated the possibility of a Russian invasion as greater than many commentators, with a Community Prediction in mid-January indicating invasion was more likely than not. This was the history of the community’s steadily increasing forecast on whether Russia would invade Ukraine in 2022, before the invasion on the 23rd of February:

• 35% on Dec 12th
• 52% on Jan 18th
• 65% on Feb 12th
• 75% on Feb 19th
• 89% on Feb 22nd

Our aim at Metaculus is to serve as a trustworthy source of information on likely outcomes, and to help people take action to avert unnecessary suffering.

We strongly believe that credible forecasting can help clarify and ground discussions, while pointing to opportunities for de-escalation. We appreciate the contributions of the entire forecasting community to this series
