Both are Kalshi contracts, structured as discrete binary tiers: one asks whether the library opens before July 2026, the other before January 2027. The tiered structure lets traders price sequential probability, with the July contract implying a nearer-term opening and the January contract capturing residual probability. Resolution follows Kalshi staff determination based on the institution's official opening announcement.",
