Which coalition will form the next Swedish government?

According to the latest prediction market data for the query “Which coalition will form the next Swedish government?”, traders have formed a strong consensus.

Currently, S + MP + C + V is dominating the market with an overwhelming 22.5% chance of winning. S follows in second place at 19.5%, while S + MP sits in third with 18.5%. The betting volume for this specific market has already reached $81.3K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• S + MP + C + V (22.5%): Currently commanding the highest probability, S + MP + C + V is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 23¢, signaling a high degree of market conviction. This contract alone has generated $12.6K in volume.

🥈 Tier 2: The Primary Challengers

• S (19.5%): Positioned as the most viable alternative, S maintains a 19.5% chance of resolving true. Its “Buy Yes” shares currently trade at 20¢.
• S + MP (18.5%): Sitting in third place with a 18.5% probability, the market shows measured skepticism toward S + MP, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~39.5%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes M + KD + L (11%), S + MP + C (9.5%), and M + KD + L + C (9.1%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like S + MP + V are still attracting notable interest.

Parliamentary elections were held in Sweden on September 13, 2026.

This market will resolve to the first ruling coalition of parties that forms after the 2026 Swedish parliamentary election.

A party will only be considered part of the ruling coalition if it provides at least one cabinet minister. Parties that merely support the government (e.g., through confidence-and-supply arrangements, parliamentary support agreements, or similar) without holding a cabinet post will not qualify.

The following parties will be considered for this market: Swedish Social Democratic Party (S), Moderate Party (M), Sweden Democrats (SD), Left Party (V), Centre Party (C), Christian Democrats (KD), Green Party (MP), and Liberals (L). All other parties will not be considered.

Resolution will be based on the listed option that most completely matches the parties included in the coalition. If the coalition formed after the election includes all of the parties listed in a market option, along with any other parties, that option will resolve to “Yes” unless there exists another market option that more completely covers the coalition. A listed option will not resolve to “Yes” if any of its listed parties are not included in the coalition.

For example:

- If the governing coalition includes S + MP + C, the option “S + MP + C” will resolve to “Yes”, while “S + MP” will resolve to “No”.

- If the governing coalition includes S + MP + KD, but no option explicitly lists those three together, the market will resolve to “S + MP” if that option is listed and no listed option more completely matches the coalition.

In the event that the ruling coalition includes all parties for multiple market options, and each option contains an equal number of coalition parties, the tie will be resolved in favor of the option whose listed parties together hold the greater number of seats in the newly elected Riksdag. If this presents another tie, this market will resolve in favor of the listed option whose parties received the greatest number of valid votes in the 2026 Swedish parliamentary election.

If any party forms a single-party government, the listed option for that party will be considered the governing coalition.

If the governing coalition does not include all parties in any listed option, this market will resolve to “Other”.

This market may resolve once the next Swedish government is officially formed following the Riksdag's vote on the Prime Minister and the taking of office by the Government.

If the next Swedish governing coalition is not confirmed by July 31, 2027, 11:59 PM ET, this market will resolve to “Other”.

This market will resolve based on a consensus of credible reporting. In case of ambiguity, this market will resolve based on official information from the Government of Sweden and the Riksdag.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome M + KD + L currently trades at 11%, but our AI places its Fair Value at just 2.1%. This creates a large negative EV Gap of -8.9%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies S + C + V as the premium value opportunity on the board. While the market only assigns it a 0.1% trading probability, our AI’s Fair Value assessment sits at 14.1% — yielding an impressive +14% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include S + V (EV Gap: +10.6%) and M + KD (EV Gap: +8.7%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
