Has Arkham's Satoshi entity page changed its wallet composition in the past 12 months, and could a labeling update alone trigger resolution without any genuine Satoshi action?

This is a long-dated binary on an essentially unknowable actor, which means the crowd systematically compresses it toward 50% — research shows all domains exhibit this 50% bias at long horizons, meaning the true probability is likely more extreme in one direction than the price suggests. The structural edge is recognizing that 'Satoshi moving coins' is historically a near-zero base-rate event across every prior year, so if this is priced anywhere near the longshot range, the favorite-long shot bias likely inflates the 'Yes' side beyond its true probability.

ResolutionResolution depends entirely on Arkham's wallet labeling — if Arkham adds or removes wallets from its Satoshi entity page (which it has done historically as new intelligence emerges), a transaction from a newly labeled wallet could trigger resolution even if there's genuine debate about ownership. The fallback 'consensus of credible sources' is dangerously vague given that the Bitcoin community has no agreed authority on which wallets are Satoshi's, meaning a contested move could produce a genuinely ambiguous resolution.

CalibrationResearch on Polymarket's 'other' category markets broadly mirrors the crypto domain calibration pattern, where markets tend to be better-calibrated near resolution but compress toward 50% at long horizons — meaning a 'No' favorite priced well above 50% right now is likely understating the true probability of no movement. Polymarket has the worst outcome-correctness rate across major platforms at 67%, so this market's price is already starting from a less reliable baseline than comparable Kalshi contracts.

RisksThis market exists on both Polymarket and Kalshi with prices tightly aligned — that alignment means there's no cross-platform arbitrage edge here, but it also means any sudden price spike would hit both platforms simultaneously, making it hard to exit quickly if you're on the wrong side of a surprise move. The high daily volatility with negative autocorrelation (price reversals are common) suggests the market is prone to rumor-driven spikes that quickly fade — traders who react to noise will systematically pay unfavorable prices, which research shows is enough to turn above-average accuracy into negative returns.

Questions worth asking

Has Arkham's Satoshi entity page changed its wallet composition in the past 12 months, and could a labeling update alone trigger resolution without any genuine Satoshi action?
Is the 'Yes' side priced as a longshot, and if so, is the implied probability higher than the actual historical base rate of Satoshi wallet movement in any prior year?
Given the negative autocorrelation in price swings, is there a systematic pattern of rumor-driven spikes that an automated or limit-order strategy could exploit by fading the moves?

The contract has moderate resolution risk due to dependency on Arkham's Intel Explorer labeling accuracy and wallet attribution—there's potential ambiguity about which wallets actually belong to Satoshi, as this is inferred intelligence rather than official confirmation. The fallback to 'consensus of credible sources' if Arkham becomes unavailable introduces additional subjectivity, though the on-chain transaction criteria itself (Outflow or Swaps) is technically objective and verifiable.

This market will resolve to “Yes” if any wallet labeled as belonging to Satoshi Nakamoto on Arkham’s Intel Explorer shows an “Outflow” or “Swaps” transaction at any time between January 9, 2026, 1:00 PM ET and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No.” The resoluti...
