Dark pool flow is positioning long ahead of tomorrow's CPI print. Institutional money quietly accumulating $SPY and $QQQ into the number.

This is the tell before the headline. When the big blocks move off-exchange into the print, they're either hedging a known outcome or front-running a dovish surprise. Either way, the gamma setup into CPI is asymmetric — if the number runs cool, we rip. If it's hot, the put wall gets tested hard.

Watch the first 15 minutes post-data. If dark pool was right, you'll see immediate follow-through in lit markets. If they're wrong, the unwind is fast and ugly.
