how to read this
Whale money is genuinely split here. Frances Tiafoe took 52% of the buy volume and Daniil Medvedev took 48%, 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 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 — Frances Tiafoe last traded at 99.9¢ on 2026-09-06 — so this page is a record of how large wallets positioned while the question was still open.
