how to read this
Whale money is genuinely split here. Chicago Cubs took 70% of the buy volume and St. Louis Cardinals took 30%, 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 19 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 — St. Louis Cardinals last traded at 99.9¢ on 2026-07-30 — so this page is a record of how large wallets positioned while the question was still open.
