Currently, December 31, 2026 is dominating the market with an overwhelming 4.1% chance of winning. The betting volume for this specific market has already reached $80.1K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• December 31, 2026 (4.1%): Currently commanding the highest probability, December 31, 2026 is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 4¢, signaling a high degree of market conviction. This contract alone has generated $56.9K in volume.

This market will resolve to “Yes” if John Fetterman officially announces that he is leaving, or formally leaves, the Democratic Party by the specified date. Otherwise, this market will resolve to “No”.

For purposes of this market, "Before the Midterms" is defined to mean by November 2, 2026 at 11:59 PM ET.

Announcements from Fetterman that he will join the Republican Party, become an independent, join another political party, or otherwise cease to be a member of the Democratic Party will qualify. A consensus of credible reporting that Fetterman has formally left the Democratic Party will also suffice.

Statements criticizing the Democratic Party, voting with Republicans, endorsing Republican candidates, describing himself as bipartisan or independent-minded, or expressing disagreement with Democratic Party positions will not qualify unless accompanied by an official announcement that he is leaving the Democratic Party or a consensus of credible reporting that he has formally left the Democratic Party.

The primary resolution source for this market will be official information from John Fetterman; however, a consensus of credible reporting may also be used.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.
