The market for “Will the Fed increase interest rates by 25 bps after the July 2026 meeting?” saw a dramatic shift as the YES contract price collapsed 29.9 percentage points in the past 24 hours, falling from an estimated 36.8% to 6.9% on Polymarket’s Breaking feed as of July 15.
This price move happened amid significant whale activity, but notably, the whale net flow diverged from the price trend. Whales purchased $1.41M worth of YES contracts while selling $513K, resulting in a net $893K inflow into YES positions over the same period. This divergence indicates large traders increased exposure even as the market’s implied probability sharply decreased.
Polymarket’s overall 24-hour volume hit $1.28M, contributing to a lifetime market volume of $14.10M and involving 9,804 unique traders. Meanwhile, the on-chain Polydata YES price stood at 18.1%, a substantial difference from the 6.9% shown on Polymarket’s Breaking feed, underscoring some discrepancy between sources.
The conflicting signals between price and whale flow highlight a complex dynamic where large investors are accumulating YES contracts despite the market pricing in a much lower likelihood of a rate hike. This tension suggests active repositioning or differing interpretations of the Fed’s future moves rather than consensus consensus across participant segments.
