According to the latest prediction market data for the query “Saudi troops fighting in Yemen by...?”, traders have formed a strong consensus.

Currently, December 31, 2026 is dominating the market with an overwhelming 25% chance of winning. October 31, 2026 follows in second place at 11.5%, while October 17, 2026 sits in third with 5.5%. The betting volume for this specific market has already reached $79.4K, 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

• December 31, 2026 (25%): Currently commanding the highest probability, December 31, 2026 is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 25¢, signaling a high degree of market conviction. This contract alone has generated $22.1K in volume.

🥈 Tier 2: The Primary Challengers

• October 31, 2026 (11.5%): Positioned as the most viable alternative, October 31, 2026 maintains a 11.5% chance of resolving true. Its “Buy Yes” shares currently trade at 12¢.
• October 17, 2026 (5.5%): Sitting in third place with a 5.5% probability, the market shows measured skepticism toward October 17, 2026, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~58%)

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 October 10, 2026 (3%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like October 10, 2026 are still attracting notable interest.

This market will resolve to "Yes" if active military personnel officially affiliated with Saudi Arabia enter Yemen for combat-related military purposes by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No".

For military personnel to qualify toward a "Yes" resolution, they must be 1) officially acknowledged as active military by Saudi Arabia; 2) be publicly acknowledged to have entered Yemen for a combat-related military purpose.

For military personnel to qualify toward a "Yes" resolution they need be active duty and acknowledged as described above. Participation in a combat role is necessary for this market to resolve to "Yes" (e.g. military personnel providing training or intelligence support would not qualify toward a "Yes" resolution, however infantry engaging Yemeni forces, or personnel conducting combat operations from Yemeni soil would qualify toward a "Yes" resolution).

Only members of the regular armed forces of Saudi Arabia will qualify toward a "Yes" resolution. Foreign fighters, private military contractors, mercenaries, or any other personnel recruited, paid, trained, equipped or directed by Saudi Arabia who are not members of the Saudi Arabian armed forces will not qualify, regardless of whether they operate under Saudi command or on Saudi Arabia’s behalf. Members of the armed forces of any other state, including those operating as part of a Saudi-led coalition, will not qualify.

Personnel must be physically present on the terrestrial territory of Yemen, including its internal waters. Air or naval operations conducted from outside Yemeni territory, including air strikes, missile strikes, drone strikes and overflights, will not qualify toward a "Yes" resolution.

The primary resolution source for this market will be official information from the government of Saudi Arabia, including the Saudi Ministry of Defense; however, a consensus of credible reporting will also be used.

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 Best Value Play (Highest EV) Our model identifies October 17, 2026 as the premium value opportunity on the board. While the market only assigns it a 5.5% trading probability, our AI’s Fair Value assessment sits at 10.2% — yielding an impressive +4.7% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include October 31, 2026 (EV Gap: +2.3%) and October 10, 2026 (EV Gap: +1.9%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
