Preliminary results from Sweden's general election on Sunday, September 13, 2026, have driven a significant repricing in markets forecasting the Moderate Party's final vote share. As early counts indicated the party, led by Prime Minister Ulf Kristersson, secured between 19.8% and 19.9% of the vote, the implied probability of the party receiving "At least 19%" of the vote surged to 98% from just 15% earlier in the session.
The sharp, 83-percentage-point spike on high trading volume reflects the market's rapid convergence with the incoming election data. The move suggests traders are highly confident that the preliminary figures will hold, solidifying the Moderates' position as the country's second-largest party and slightly improving on their 2022 election performance. The broader repricing indicates a consensus that the party's final share will settle in a narrow band between 19% and 21%.
Distribution Analysis
The shift was overwhelmingly directional, with four of the five available contracts rising as preliminary results were reported. The largest increases in probability and volume were concentrated in contracts pricing a final vote share between 18% and 19%, reflecting the incoming data.
| Outcome | Current Prob | Change | Volume |
|---|---|---|---|
| At least 16% | 99% | +14.0pp | 152 |
| At least 17% | 99% | +21.0pp | 405 |
| At least 18% | 94% | +53.0pp | 737 |
| At least 19% | 98% | +83.0pp | 858 |
| At least 21% | 1% | -8.0pp | 30 |
Net: 4 of 5 contracts rose on total volume of 2,152, shifting the implied consensus range decisively higher to align with preliminary election returns.
What's Driving the Shift
The repricing appears to be a direct reaction to official data and media reports from election night.
Preliminary Vote Count: The primary catalyst for the move was the release of preliminary results as districts reported their counts. Multiple outlets, citing figures with over 90% of votes tallied, placed the Moderate Party's share at approximately 19.9 percent, surpassing the 19% threshold with a clear margin. This rendered the contract's outcome highly probable, triggering the jump from 15% to near-certainty.
Surpassing 2022 Results: The projected result represents a modest improvement over the Moderate Party's 19.10% share in the 2022 election. The pre-election probability of 15% for a result over 19% suggests the market was pricing in a possibility of a weaker performance. The stronger-than-expected preliminary result prompted a swift correction.
Capped Upside: While expectations surged, traders priced in a firm ceiling. The contract for the party receiving "At least 21%" of the vote fell to just 1%, indicating a strong consensus that the final official tally is unlikely to climb much higher than the preliminary figures.
Market Context
The market, which trades on the CFTC-regulated Kalshi exchange, is now in a phase of aligning with the official vote-counting process. The election itself remains extremely close, with the centre-left opposition bloc holding a razor-thin, provisional three-seat majority (176 to 173) over Prime Minister Kristersson's right-wing bloc.
While the overall outcome of government formation remains uncertain, the market for the Moderate Party's specific vote share reflects high confidence in the preliminary numbers. The party appears to have successfully retaken its position as the second-largest in Sweden, after the anti-immigration Sweden Democrats lost ground for the first time, dropping from 20.5% in 2022 to a projected 17.6%.
What to Watch
The contract is scheduled to settle based on the final, official results published by the Swedish Election Authority (Valmyndigheten). While the vast majority of votes have been counted, the final result will not be certified until late-arriving and overseas ballots are processed, a procedure that could take several days. The market's near-100% pricing suggests traders do not expect these remaining votes to meaningfully alter the Moderate Party's percentage.
