What it means for prediction markets
- The Democratic House-control contract led the reported whale-money totals, making it the clearest concentration of large-trade activity in this snapshot.
- Trading totals alone do not establish whether those trades favored or opposed Democratic control. The summary provides no breakdown by side or contract price.
- The 247 unsettled bets represent unresolved positions, not confirmed outcomes. The figures describe a rolling 24-hour window ending at the stated update time.
