The market for whether the Fed will increase interest rates by 25 basis points after the July 2026 meeting saw a dramatic shift in the past 24 hours, with the YES price tumbling 28.5 percentage points from 35.6% to 7.1%. This sharp decline in implied probability contrasts with whale activity, which flowed strongly into YES contracts, netting $863K over the same period.
Whales purchased $1.40M in YES contracts and sold $535K, indicating sustained demand from large traders despite the market’s steep downward repricing. The divergence between price movement and whale flow is notable, as the FLAG flow_diverges_from_price=true confirms that large traders are betting against the prevailing market sentiment reflected in the price drop.
