how to read this

One wallet drives this market: 0xfe78…0319 accounts for 74% of all whale buy volume ($185K). 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 49 cents toward 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 — Chicago Cubs last traded at 99.9¢ on 2026-08-02 — so this page is a record of how large wallets positioned while the question was still open.
