Analysis

This 30% probability reflects market participants' assessment that an AI-related entity or concept will be selected as Time's Person of the Decade when the magazine makes this selection (likely in late 2029 or early 2030). The probability is being driven primarily by AI's rapid advancement and cultural prominence in 2024-2026, though the specific designation remains uncertain. A runner-up outcome sits at 13%, indicating significant fragmentation across alternative outcomes. The main factors depressing the full probability are uncertainty about whether Time will choose a person, organization, or concept; the unpredictable editorial preferences of Time's selection committee; and competition from major political figures and other potential contenders. Resolution will occur when Time officially announces its Person of the Decade selection, likely at year-end 2029 or in early 2030, at which point the market will settle definitively.

  • The leading outcome prices AI at 30¢, while the runner-up is at 13¢, indicating significant market uncertainty and a fragmented field of potential winners
  • Donald Trump trades at 26¢, making him the second-highest individual person within this market, suggesting political figures remain credible contenders
  • The five most liquid contracts (AI, Trump, Zohran Mamdani, Pope Leo XIV, and others) collectively represent a minority of the probability space, with remaining outcomes distributed across other unspecified candidates
  • Time's selection criteria and editorial judgment are not mechanically determined by any public metric, creating irreducible uncertainty for all participants
  • Resolution is approximately 3-4 years away, allowing substantial shifts in global circumstances that could favor different outcome categories

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.
