The probability that the Federal Reserve will increase interest rates by 25 basis points after the July 2026 meeting rose sharply by 15.0 percentage points over the last 24 hours, climbing from 21.9% to 37.0% on Polymarket’s Breaking feed. This notable repricing was accompanied by strong whale activity, with 182 unique whales contributing a net $175K inflow into YES contracts. Total whale buy volume reached $348K, nearly double the $173K in sell volume, indicating that large traders moved in concert with the price surge.
Despite this, the Polymarket Breaking YES price of 37.0% stands in stark contrast to the Polydata on-chain midprice of 3.0%, underscoring a significant divergence between the real-time market sentiment and the on-chain aggregated data. The 24-hour total trading volume was $295K, reflecting elevated interest in this contract, which has amassed a lifetime volume of $12.65M and engaged 9,629 unique traders since inception.
This alignment of whale flows and a sharp price increase suggests that influential market participants are backing a higher likelihood of a rate hike in July 2026. The combined evidence points to a shift in market expectations, with large investors reinforcing the tape’s bullish repricing of this outcome.
