What conspiracy theories will be proven true by 2100? (Mega Market)

Question

What conspiracy theories will be proven correct by 2100. The conspiracy theory must have been true in 2024 so if the US government gets aliens after 2024 but didn't have them before it doesn't count. Please add your own conspiracy theories. I will be lenient in what is considered a conspiracy theory. If something is widely considered to be true in 2100 it will count as a yes resolution but to resolve beforehand it must be definitively proven and verified by multiple news sources. anything not proven true by 2100 will resolve no. Feel free to ask clarifying questions. In will not bet on this market in case of controversy
