Analysis

4d ago

This market shows extreme illiquidity with only $3 open interest and zero 24-hour volume, making the 53¢ price potentially unreliable for serious positioning. The 90.8% implied yield on the "No" side is notably high relative to the 51.7% "Yes" yield, suggesting the market may be underpricing the probability of a Rubio announcement given his prominence and the typical timing of presidential campaign declarations. With 533 days to expiration and minimal trading activity, this appears to be a thin, speculative market where the wide 7¢ spread reflects low confidence in price discovery.

Resolution rules

If Marco Rubio has announced that they will run for President of the United States in 2028 before Oct 1, 2027, including running for the nomination of any political party to contest that office, then the market resolves to Yes.
