how to read this
This is not a directional bet. 3 wallets put $114K into Yes at around 99.9¢ — an outcome the market already priced as all but decided. The trade on offer here is the last few cents of the dollar, not a call on the result, and reading it as smart-money conviction would be wrong.
The flow is spread across 3 wallets with the largest at 43% ($49K) — several participants independently taking the same yield, which is what an efficient market looks like rather than a signal.
The market has since converged — Yes last traded at 99.9¢ on 2026-09-14 — so this page is a record of how large wallets positioned while the question was still open.
