Analysis

This probability reflects market expectations that Jeff Bezos will rank as the third-wealthiest person globally on December 31, 2026. The 38% probability sits between runner-up Sergey Brin at 35% and Mark Zuckerberg and Jensen Huang each at 28%, indicating meaningful uncertainty about wealth rankings over the next eight months. Wealth positions depend primarily on stock market movements—particularly Amazon's share price for Bezos and other major holdings for competitors—as well as asset sales or acquisitions by these individuals. The final ranking will be determined by net worth calculations published by wealth tracking services on or near year-end 2026. Key drivers include whether Bezos continues Amazon shareholding patterns, whether tech stock valuations shift dramatically, and whether any billionaire executes major capital transactions affecting their portfolio composition.

  • Amazon stock performance and Bezos's holdings changes between now and December 31, 2026
  • Tesla, xAI, and Elon Musk's total assets relative to other candidates, as he currently leads richest-person forecasts at 89%
  • Aggregate tech sector valuation shifts, which would affect Zuckerberg (Meta), Huang (Nvidia), and Brin holdings simultaneously
  • Any major asset sales, acquisitions, or wealth transfers by Bezos or competing billionaires that would alter net worth calculations
  • Methodology used by wealth tracking services in December 2026 for valuing private holdings and illiquid assets

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
