how to read this

This is not a directional bet. 18 wallets put $1.46M into No at around 99.8¢ — 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 18 wallets with the largest at 28% ($234K) — several participants independently taking the same yield, which is what an efficient market looks like rather than a signal.

The market has since converged — No last traded at 99.9¢ on 2026-09-16 — so this page is a record of how large wallets positioned while the question was still open.
