Will there be a blue wave, by this market's definition? It asks whether Democrats will hold 218 or more House seats and 49 or more Senate seats. The market page counts down to Tuesday, November 3 at 8:00 a.m. ET and lists a February 1, 2027 expiration.
Blue Wave Odds: Democrats 218+ House and 49+ Senate (YES 87.7¢, +11.7 pts)
Traders are treating a Democratic breakthrough in both chambers as the base case, and the blue wave odds of 87.7¢ for YES imply an 87.7% chance, a +11.7 pts move on the board. The chart opens near 76% in December, bottomed near 59% early in the year, and has pushed back into the high 80s since late summer.
The Senate half carries more of the uncertainty. Democrats hold 47 seats today, so 49 takes a net gain of two, and the final New York Times/Siena battleground surveys showed Democratic candidates ahead in Michigan, Texas, Kansas, Maine and Ohio.

Midterm Blue Wave Price Analysis: Market Price Influencers
The loudest driver behind the midterm blue wave price is the national environment. The RealClearPolling generic ballot average showed Democrats ahead 51.5% to 43.4% on October 27, FiftyPlusOne's average had the lead at 9 points on November 1, and the final Times/Siena poll put it at 11 with President Trump's approval at 34%.
Forecast models give the blue wave odds some backing. CNN's Harry Enten gave Democrats a 92% chance at the House and 71% at the Senate in his final forecast, while Silver Bulletin put Democratic Senate control at 80.1%. Because the contract's Senate bar of 49 seats sits two below the 51 Democrats need to control the chamber with Vice President JD Vance holding the tiebreaker, that leg is a lower bar than the control question those models answer.
Fox News' final Power Rankings point the same way, with Democrats favored in 48 Senate seats, one short of the contract's mark, and a House floor of 223 seats against a ceiling of 240. Ohio sits at Lean D while Kansas and South Carolina are Toss-ups, so a single close race can decide whether this contract pays.
The risks sit on the polling side. The Times' own analysis noted that Democrats are responding to its surveys at a much higher rate than Republicans, with registered white Democrats about 30% likelier to take a poll than registered white Republicans, and polls have overstated Democrats in recent Trump-era cycles. Republicans also redrew House maps across the South, which makes 218 harder to reach than the national margin alone suggests.
Will there be a blue wave on election night? Returns from Senate battlegrounds like Texas, Kansas, Ohio and Maine will reprice the board in real time, and a close House count could keep the answer in doubt well past Tuesday.

Final Thoughts on the Midterm Blue Wave
So, will there be a blue wave? Kalshi's answer is a firm yes, with the midterm blue wave priced at 87.7¢ and nearly every major forecast leaning the same direction.
This is a crowded consensus market. At 87.7¢ a YES share offers 12.3¢ of upside against 87.7¢ at risk, so the blue wave odds have already absorbed the generic ballot, the forecast models and the Senate polling, and they leave little room for a surprise.
The one variable to watch is the Senate battleground polling. The House has a cushion above 218 in most forecasts, while Democrats still need to win at least one toss-up to reach 49.
