Currently, December 31, 11:59 PM is dominating the market with an overwhelming 99.6% chance of winning. November 30, 11:59 PM follows in second place at 97.7%, while November 15, 11:59 PM sits in third with 94%.

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, 11:59 PM (99.6%): Currently commanding the highest probability, December 31, 11:59 PM is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 100¢, signaling a high degree of market conviction. This contract alone has generated $3.0K in volume.

🥈 Tier 2: The Primary Challengers

• November 30, 11:59 PM (97.7%): Positioned as the most viable alternative, November 30, 11:59 PM maintains a 97.7% chance of resolving true. Its “Buy Yes” shares currently trade at 98¢.
• November 15, 11:59 PM (94%): Sitting in third place with a 94% probability, the market shows measured skepticism toward November 15, 11:59 PM, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

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 November 10, 11:59 PM (92.5%), November 13, 11:59 PM (92.1%), and November 5, 11:59 PM (87%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like November 6, 11:59 PM are still attracting notable interest.

This market will resolve to “Yes” if the Associated Press has, by the specified date and time (ET), called control of the United States House of Representatives for the Congress that will convene following the midterm elections. Otherwise it will resolve to “No”.

Control of the House of Representatives will be considered to have been called when the Associated Press has either 1) issued a call that House control has been determined, or 2) issued race calls declaring winners in at least 218 districts for candidates of the same party, with all such calls standing at the same time for 1 hour without retraction. Independents will not be considered members of a party for purposes of this count.

Under condition 1, no subsequent withdrawal of a control call will be relevant to this market.

Under condition 2, this market will remain open for one hour following the race call that brings a party’s standing calls to 218. If, within that hour, the Associated Press retracts any of those calls such that the party’s standing calls fall below 218, condition 2 will not be considered satisfied by that call. If no such retraction occurs within the hour, condition 2 will be considered satisfied as of the time of the 218th call, regardless of any later retraction. For resolution, the relevant time is the time of the 218th call, not the end of the one-hour period.

The resolution source for this market will be the Associated Press.

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 November 3, 11:59 PM currently trades at 50.5%, but our AI places its Fair Value at just 32%. This creates a large negative EV Gap of -18.6%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies November 4, 3:59 AM as the premium value opportunity on the board. While the market only assigns it a 65% trading probability, our AI’s Fair Value assessment sits at 75.5% — yielding an impressive +10.5% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include November 4, 12:59 AM (EV Gap: +2.1%) and November 6, 11:59 PM (EV Gap: +1.2%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
