The probability that Ralph Norman will become the Republican nominee for Senate in South Carolina rose sharply by 17.0 percentage points over the last 24 hours, climbing from 6.5% to 23.5% on Polymarket.
This surge in YES price was supported by whale activity, with 40 unique whales collectively buying $8K worth of YES contracts and selling $4K, resulting in a net $4K inflow into YES positions. The alignment of whale flow with the price move confirms that large traders were behind the sudden shift in odds.
Overall trading volume on Polymarket for this market reached $6K in the past 24 hours, contributing to a lifetime market volume of $31K across 121 unique traders. The concentration of whale buying during this period signals increased conviction among high-value participants that Norman’s nomination chances have improved significantly.
The combined effect of the substantial price jump and confirming whale flow marks a notable repricing of Norman’s prospects. This development highlights how concentrated whale buying can accelerate shifts in market sentiment on Polymarket, especially in markets with previously low implied probabilities.
