Which coalition will form the next New Zealand government?

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

Currently, National + ACT + NZF is dominating the market with an overwhelming 49.5% chance of winning. Labour + Green follows in second place at 28.4%, while Labour + Green + Maori sits in third with 15.5%. The betting volume for this specific market has already reached $115.2K, 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

• National + ACT + NZF (49.5%): Currently commanding the highest probability, National + ACT + NZF is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 50¢, signaling a high degree of market conviction. This contract alone has generated $21.1K in volume.

🥈 Tier 2: The Primary Challengers

• Labour + Green (28.4%): Positioned as the most viable alternative, Labour + Green maintains a 28.4% chance of resolving true. Its “Buy Yes” shares currently trade at 28¢.
• Labour + Green + Maori (15.5%): Sitting in third place with a 15.5% probability, the market shows measured skepticism toward Labour + Green + Maori, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~6.6%)

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 Other (6.2%), National + ACT (1.1%), and National + Labour (0.3%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like Labour + NZF are still attracting notable interest.

A general election is scheduled to be held in New Zealand on November 7, 2026.

This market will resolve to the first ruling coalition of parties that forms after the next New Zealand general election.

A party will only be considered part of the ruling coalition if it participates in the governing coalition and provides at least one Cabinet minister. Parties that merely support the government from outside Cabinet, including through confidence-and-supply agreements or similar arrangements, without holding a Cabinet post will not qualify.

The following parties will be considered for this market: ACT New Zealand (ACT), Labour Party (Labour), Te Pāti Māori (Maori), National Party (National), Green Party (Green), and New Zealand First Party (NZF). 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 Labour + Green + ACT, but no option explicitly lists those three together, the market will resolve to “Labour + Green” if that option is listed and no listed option more completely matches the coalition.

- If the governing coalition includes National + ACT + NZF, the option “National + ACT + NZF” will resolve to “Yes”, while “National + ACT” will resolve to “No”.

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 House of Representatives. If this presents another tie, this market will resolve in favor of the listed option whose parties received the greatest number of valid party votes.

If any party forms a single-party majority 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 first government is officially confirmed following the appointment of the Prime Minister and ministers by the Governor-General after the 2026 New Zealand general election, with ministers appointed under non-caretaker circumstances.

If the next New Zealand ruling coalition after the election is not confirmed by December 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 New Zealand.

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 Labour + Green currently trades at 28.4%, but our AI places its Fair Value at just 19.9%. This creates a large negative EV Gap of -8.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Labour + Green + Maori as the premium value opportunity on the board. While the market only assigns it a 15.5% trading probability, our AI’s Fair Value assessment sits at 18.1% — yielding an impressive +2.6% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Labour + Maori + NZF (EV Gap: +1%) and Labour + Green + Maori + NZF (EV Gap: +0.1%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
