how to read this
This is not a directional bet. 2 wallets put $108K into Boston Red Sox 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.
It is also mostly one actor: the largest wallet is 100% of the buy flow ($15K), so this is a single desk parking money rather than a crowd doing the same trade.
The market has since converged — Boston Red Sox last traded at 99.9¢ on 2026-07-17 — so this page is a record of how large wallets positioned while the question was still open.
