Analysis
This illiquid market shows a significant cross-venue arbitrage opportunity, trading at 11¢ on Kalshi versus 18¢ on Polymarket—a 64% price gap suggesting either mispricing or venue-specific liquidity constraints. The extreme implied yield of 4596.8% on the Yes side reflects the tiny position size ($168 open interest) and wide 8¢ spread rather than genuine expected returns, indicating minimal conviction from traders. The 7-cent price increase over seven days combined with zero 24-hour volume suggests this market may be stale, and with 257 days to expiry, the Cliff Risk Index of 32 signals meaningful uncertainty about eventual resolution mechanics.
