The probability that the Fed will increase interest rates by 25 basis points after the July 2026 meeting dropped sharply, with the YES contract price falling 28.4 percentage points from 35.5% to 7.0% over 24 hours. Despite this steep decline in price, whale investors bought aggressively, contributing a net $883K into YES contracts amid $1.41M in buy volume versus $527K in sell volume from 244 unique whales.
This divergence between whale flow and price movement is notable. While the overall Polymarket 24-hour volume for this market was $1.29M, whale activity alone accounted for a significant portion of the trading, indicating that large traders were increasing their exposure to the YES outcome even as the market repriced it substantially lower.
The lifetime market volume stands at $14.07M with 9,798 unique traders participating, underscoring the depth and interest in Fed rate decisions as a key economic indicator.
In sum, the market’s sharp repricing combined with strong whale buying reveals a complex dynamic in expectations around the Fed’s July 2026 rate decision, reflecting uncertainty or strategic positioning among major participants.
