how to read this
This is not a directional bet. 5 wallets put $115K into Alexander Zverev at around 92¢ — 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 5 wallets with the largest at 48% ($55K) — several participants independently taking the same yield, which is what an efficient market looks like rather than a signal.
The market has since converged — Alexander Zverev last traded at 99.9¢ on 2026-08-18 — so this page is a record of how large wallets positioned while the question was still open.
