Kalshi prices climb for Democrats to clear paired congressional seat targets

Kalshi’s Blue Tsunami market has reached 68 percent for Democrats winning at least 235 House seats and 51 Senate seats, up from 35 percent in early July, according to Kalshi News.

The update, published Nov 3, 2026 at 2:30 PM ET, puts the market’s implied probability 33 percentage points above its early-July level.

Related market also advances

The related Mega Tsunami market has increased from 8 percent in September to 32 percent, according to Kalshi News. The supplied summary does not specify that contract’s settlement requirements.

The increases came as final New York Times and Siena polls showed Democratic candidates ahead in seven competitive Senate races, Kalshi News reported. Those polling leads are distinct from election results and do not establish whether either contract’s conditions will be satisfied.

Two thresholds govern Blue Tsunami

The Blue Tsunami contract requires Democrats to meet both seat thresholds: at least 235 in the House and 51 in the Senate. Reaching only one would not fulfill the contract’s stated conditions.

That joint requirement matters when interpreting the Senate polling. Leads in seven competitive races speak to one chamber, while the contract also depends on the House outcome.

What it means for prediction markets

• Joint outcome: The 68 percent pricing applies to Democrats meeting both congressional seat targets, not either threshold independently.
• Separate contracts: Mega Tsunami’s rise to 32 percent is another market move, but its unspecified settlement criteria limit direct comparison with Blue Tsunami.
• Evidence versus resolution: The Senate polls provide context for the repricing; they do not resolve the contracts or establish that the House threshold will be met.
