how to read this
Whale money is genuinely split here. Mirra Andreeva took 64% of the buy volume and Coco Gauff took 36%, so large wallets are on both sides of this question. There is no whale consensus to follow.
Between those entries and the last print the market moved 46 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 — Coco Gauff last traded at 99.9¢ on 2026-09-09 — so this page is a record of how large wallets positioned while the question was still open.
