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

• $4.00-$4.50T (5,290%): Currently commanding the highest probability, $4.00-$4.50T is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 5,290¢, signaling a high degree of market conviction. This contract alone has generated $1.0K in volume.

🥈 Tier 2: The Primary Challengers

• $3.50-$4.00T (4,150%): Positioned as the most viable alternative, $3.50-$4.00T maintains a 4,150% chance of resolving true. Its “Buy Yes” shares currently trade at 4,150¢.
• $4.50-$5.00T (800%): Sitting in third place with a 800% probability, the market shows measured skepticism toward $4.50-$5.00T, 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 <$3.50T (145%), $6.00T+ (55%), and $5.50-$6.00T (45%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like $5.00-$5.50T are still attracting notable interest.

This market will resolve according to Alphabet's public market capitalization at the close of regular trading on the final trading day of the specified month.

If the determined value falls exactly on the boundary between two brackets, this market will resolve to the higher bracket.

Public market capitalization will be determined through appropriate calculation using the final official regular-hours closing prices published for the company's listed equities on its primary exchange for the last trading day of the specified month, multiplied by the company's total number of shares outstanding at the relevant time. If necessary, to accurately capture the company’s total market capitalization, rather than a stock-class-specific market capitalization, the calculation will include all outstanding share classes and apply any stated conversion ratios to the publicly traded class. Where no conversion right exists, such shares will be counted at their stated outstanding amount without discount, unless official filings explicitly specify differently. The number of outstanding shares will be determined from official company filings or disclosures (e.g., SEC filings).

If the listed company merges with or acquires another entity and remains the parent company, no change to resolution methodology applies.

If the listed company is acquired, merges into another entity and is no longer the surviving parent company, or otherwise ceases to exist as an independent entity prior to the end of the period, the public market capitalizations achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution.

The resolution source for this market is official exchange trading data and publicly reported share counts.
