Polymarket’s contract on whether “Will Swim – BTS be the top song for 2026?” saw a notable shift in market sentiment over the past 24 hours, with the YES price dropping 16.0 percentage points from around 57.5% to 41.5% as of the July 19 snapshot. This sizable repricing reflects a significant change in trader expectations about the song’s chances.
Despite the steep decline in the contract’s YES price, whale activity diverged from the price move. Large bettors did not follow the downward trend; instead, their flow moved against the price, signaling a net position that contrasts with the broader market’s sell-off. This divergence between whale flow and price action highlights a complex dynamic where retail and institutional players are at odds.
Trading volume for this market over the last 24 hours was $13K, underscoring steady liquidity but not an extraordinary surge in activity. The split between price and whale flow suggests that while general market sentiment has soured on the likelihood of “Will Swim” topping 2026 charts, significant bets remain positioned on the YES outcome.
This pattern indicates a contested market narrative: the broader Polymarket community has lowered their probability on this outcome sharply, but major players are maintaining or increasing their exposure, possibly anticipating a different outcome than the crowd.
