The identity is unknown. The user had only a cryptographic address for identification.

Odds Fluctuate Before News Break

Platform data shows that traders estimated the likelihood of the president's removal at just 6.5% in the midday period of the Friday before the event.

However the odds had climbed to 11% by shortly before midnight and skyrocketed in the morning of January 3rd, indicating a rapid movement in betting activity immediately prior to the social media post was made.

"This particular bet has all the signs of a transaction based on inside information," commented Dennis Kelleher.

A handful of other individuals also made tens of thousands of dollars from bets on the same outcome.
