What it means for prediction markets
- Political contracts drew the most activity: Politics represented more than half of the top 50 markets and most of their reported 24-hour volume.
- Congressional control was the leading individual market: The 2026 Midterms Congress Balance of Power contract topped the ranking with 3.5 million dollars traded.
- Volume is not a forecast: Without prices or probability changes, the figures show where trading was concentrated—not which outcomes became more likely.
