Contract brief

This market will resolve to "Yes" if definitive evidence confirming that Adam Back is Satoshi Nakamoto, the pseudonymous creator of Bitcoin, is made public by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Qualifying evidence includes, but is not limited to, verified documentation, blockchain evidence, or other definitive evidence. If Satoshi Nakamoto is conclusively identified as a group or collective rather than a single individual, definitive evidence that Adam Back was a member of that group will qualify. Unverified or anonymous claims, speculation, memes, jokes, sarcasm, or unsubstantiated reports will not qualify. The primary resolution source will be a consensus of credible reporting.

Resolution Risk Premium: Pricing the Rule, Not the Outcome

When the resolution rule is fuzzy, the price is the market's estimate of how the rule will be interpreted, not the outcome's probability. Three case studies and the discount math.

Liquidity Availability Is the Real Edge in Prediction Markets

Implied yield, cliff risk, and overround all describe what to trade. Liquidity Availability Score describes whether the orderbook can absorb the trade. Why LAS is the indicator that decides who actually books P&L.

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.
