38. The Sale of Alaska by Russia
Year: 1867
Location: Alaska
Company: Russian Government
Estimated Damage Value: Unknown
If Russia hadn’t sold Alaska to the US in 1867 for $7.2 million, the financial outcome could’ve been significantly different. The potential earnings from retaining Alaska are a monumental what-if in history.

Since the sale, Alaska’s oil and gas sector generated 17 billion barrels of oil, contributing to a state GDP of $49 billion. This lost revenue highlights a major economic opportunity Russia missed out on.
