how to read this
One wallet drives this market: 0x6d20…a165 accounts for 69% of all whale buy volume ($218K). That makes this one desk's position rather than a crowd view — the concentration is the story, and it means a single actor's change of mind would move the whole picture.
Between those entries and the last print the market moved 3 cents against the side whales bought. That is the distance between two observed prices, not a profit: we do not know which of these wallets are still holding.
The market has since converged — St. Louis Cardinals last traded at 99.9¢ on 2026-08-27 — so this page is a record of how large wallets positioned while the question was still open.
