Will a player from the Republic of Korea win the 2026 U.S. Open?

Why

Probability fell modestly down to 0¢ (toward NO) over the last 24 hours, a 4.8pp shift. Resolution depends on to the listed nationality of the 2026 us open champion — directional traders may be reading new information from that source.

What to verify

• Cross-check the resolution source: to the listed nationality of the 2026 US Open champion.
• Read recent large-trade flow on Orrery's market page — $5k+ trades show up alongside the move so you can tell if size is following the price or fading it.
