- Democrat sweep odds hit a record 67% on Polymarket — up from 24% one year ago

Prediction market odds for a Democrat sweep in the 2026 US Midterm elections have surged to a record 67%, according to data shared by @KobeissiLetter on X. One year ago, the same markets assigned just a 24% probability to that outcome — a 43-percentage-point shift in 12 months.
The Polymarket chart — tracking the 2026 Balance of Power through September and October — shows the Democratic sweep line holding a gradual upward trajectory before a near-vertical spike at the far right edge, landing at 67%. The Republican sweep line, by contrast, has declined steadily to just 8%. The remaining scenarios split between divided chamber outcomes: R Senate/D House at 27% and D Senate/R House at under 1%. Total volume on the contract stands at $18,009,599.
Election Day is 29 days away. At current odds, the prediction market is pricing a Democrat sweep as the most probable single outcome by a wide margin — nearly eight times more likely than a Republican sweep. For crypto markets, a Democrat-controlled Congress in 2027 would reopen legislative questions around digital asset regulation that stalled under the prior Republican majority, a dynamic worth tracking alongside broader macro positioning.
