Will Arizona have the longest losing streak in the 2026 Pro Baseball regular season?

This market shows a dramatic 29-cent cross-venue arbitrage gap, with Kalshi pricing Arizona's chances at just 2% versus Polymarket's 31% valuation—a 15.5x discrepancy that suggests significant mispricing on one platform. The Kalshi contract is severely illiquid with zero 24-hour volume and minimal $25 open interest, making the 2¢ price potentially unreliable and vulnerable to manipulation. The 1¢ spread is wide relative to the absolute price level, and with nearly two years until October 2026 expiry, this appears to be a thin, neglected market where the low Kalshi price may simply reflect poor price discovery rather than genuine conviction about Arizona's losing streak prospects.
