The Polymarket contract asking whether the Fed will increase interest rates by 25 basis points after the July 2026 meeting saw a dramatic drop in its YES price, falling 28.1 percentage points from 35.2% to 7.0% over the past 24 hours as of July 15.
Despite this sharp decline in market-implied probability, whale activity diverged from the price move. Large traders bought a net $880K into YES contracts, with $1.41M in buy volume against $527K in sell volume across 247 unique whales. This contrasts with the tape’s bearish repricing, as the overall 24-hour volume was $1.28M, below the whale buy volume alone.
Adding to the complexity, the Polymarket Breaking YES price at 7.0% differs markedly from Polydata’s on-chain mid-price of 18.1%, indicating a split between the live market feed and aggregated on-chain data.
The market’s lifetime volume stands at $14.06M with 9,792 unique traders, showing sustained interest despite the recent volatility. The divergence between whale buying and price decline suggests conflicting views among large traders versus the broader market sentiment.
This combination of a steep drop in price alongside substantial whale buying highlights an unsettled outlook on the Fed’s July 2026 rate decision, reflecting a market in flux rather than consensus.
