Analysis
This market shows extreme annualized yields exceeding 2,700% despite fair-value pricing at 50¢, driven entirely by the 14-day expiration window compressing time value into outsized percentage returns. The $4.6M open interest with only $22 in daily volume reveals severe liquidity constraints and potential difficulty exiting positions, while the 822% realized volatility and 1.31 vol ratio suggest significant price swings are expected in the final two weeks before resolution. With neutral regime conditions and modest recent price appreciation from 47¢ to 50¢, the market appears fairly balanced on the binary outcome, but traders should be cautious of cliff risk given the thin trading activity and imminent April 30 deadline.
Resolution rules
This market will resolve to “Yes” if Bitcoin comparatively outperforms the S&P 500 (SPX) in the listed month, with performance measured as the percentage change in price during the month for each asset. Otherwise, this market will resolve to “No”. The percentage change in price for Bitcoin will be calculated by comparing the "Close" price for the Binance 1 minute candle for BTC/USDT on the last day of the specified month in the ET timezone to the "Close" price for the Binance 1 minute candle for BTC/USDT on the first day of the specified month, 12:00 AM in the ET timezone (https://www.binance.com/en/trade/BTC_USDT). The percentage change in the S&P 500 (SPX) will be calculated by comparing the official S&P 500 (SPX) Close price for the last trading day of the specified month to the official S&P 500 (SPX) Close price for the last trading day before the specified month, as reported by the Wall Street Journal (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices). If either of the relevant days has no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. Exactly equal performance of both assets will not suffice for a "Yes" resolution. The resolution sources for this market are Binance, specifically the BTC/USDT "Close" prices currently available at https://www.binance.com/en/trade/BTC_USDT with "1m" and "Candles" selected on the top bar, and the Wall Street Journal, specifically the Close values published by the WSJ under "Historical Prices" (US: https://www.wsj.com/market-data/stocks, EMEA: https://www.wsj.com/market-data/stocks/emea, ASIA: https://www.wsj.com/market-data/stocks/asia).
