This sharp repricing coincided with significant whale activity supporting the move. Whale investors contributed a net $2.27 million in purchases of YES contracts, with $4.08 million in buys and $1.81 million in sells recorded among 470 unique whales over the same period. The alignment of whale flow with the price increase underscores a strong consensus among large traders betting on no rate change.
Overall market volume for this contract reached $3.00 million in the past day, adding to a lifetime total of $25.52 million. Meanwhile, the broader Polymarket platform shows 6,016 unique traders have participated in this market.
Notably, the Polymarket Breaking YES price of 92.5% differs from the on-chain Polydata mid-price, which stands at 80.5%, indicating some divergence in pricing sources but consistent directional conviction.
This combined surge in price and whale buying activity signals a substantial shift in market expectations toward the Fed maintaining current rates after July 2026, reflecting either new information or changing sentiment among sophisticated traders.
