On-chain data platform Arkham announced via X that "if Michael Saylor sold Bitcoin yesterday, its prediction market participant 'Surprised-Legacy' will receive $200,000." However, the market has not yet been settled. Arkham explained that the result will be finalized only after MicroStrategy's 8-K filing confirms whether Bitcoin was sold last week. Currently, the prediction market estimates the probability of MicroStrategy having sold Bitcoin at 11%.
