What Prediction Markets Are Forecasting

Prediction markets currently give Bernie Sanders roughly a 1 in 10 chance of running for President in 2028. With a 9% probability, traders collectively see another campaign as very unlikely. This is a low-confidence forecast, suggesting most participants expect Sanders to conclude his political career without another presidential bid.

Why the Market Sees It This Way

Two main factors explain the low odds. First, Sanders will be 87 years old on Election Day 2028. While he has remained active, age is a significant practical consideration for a national campaign. Second, his stated political mission has shifted. After the 2020 election, Sanders focused on consolidating progressive influence within the Democratic Party and supporting other candidates, rather than preparing for another personal run. His last campaign framed itself as a "political revolution" to shift the party's direction, a goal he now seems to pursue from the Senate.

Historical context also matters. Sanders' 2016 and 2020 runs were historic for their grassroots support, but they also followed a pattern. He entered both races as an insurgent candidate against an established party frontrunner. In 2028, there is no clear similar scenario, and the progressive lane he championed may be occupied by younger politicians.

Key Dates and Events to Watch

Watch for signals in the 2026 election cycle. If Sanders campaigns heavily for specific progressive candidates, it could indicate he is building a movement for someone else, not himself. His public statements about the 2028 field will be telling, especially if he endorses a candidate early. Any significant change in his health or Senate activity could also shift these predictions, but the main window for a shift would likely be in early 2027, when potential candidates typically begin forming exploratory committees.

How Reliable Are These Predictions?

Markets are generally reliable for forecasting candidate entry in races that are two or more years away, as they aggregate many opinions about personal and political calculations. However, they can be less accurate for unique situations involving singular figures like Sanders. The low trading volume on this question also means the price is more sensitive to new information. The biggest limitation is the unpredictable nature of personal decisions, especially for someone who has defied political norms before.
