how to read this
The flow is broad rather than concentrated: 3 whale wallets put 100% of their buy volume on the same side, with the largest single wallet at 49%. Agreement at that width is harder to dismiss as one trader's idea, though it is still agreement about odds, not about the outcome.
Between those entries and the last print the market moved 37 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 — Mees Rottgering last traded at 99.9¢ on 2026-08-26 — so this page is a record of how large wallets positioned while the question was still open.
