[Whale Watch] $5K NO on S&P 500 Price Above $6,699.99 on March 16, 2026 at 3:54:53 PM ET
The Trade
Someone just bet $5,091 that the S&P 500 will not close above $6,699.99 at 4pm EDT on March 16, 2026. They bought 5,989 NO contracts at 15 cents each, spending $5,091 total. At 15 cents, the market implies roughly a 15% chance that YES wins — meaning the market thinks there is about an 85% chance the S&P stays at or below that level. This was the largest of three descending-price sweeps: an earlier buyer paid 27 cents at 3:53:38 PM, then 20 cents at 3:54:16 PM, then this whale swept 5,989 contracts at 15 cents. That rapid stair-step suggests aggressive selling of YES contracts across multiple price levels.
The Price Impact
Before these trades hit, YES contracts were trading around 39 cents. After the sweep, the last trade printed at 34 cents — a 22-cent drop from the session high of 39 cents. The current bid is 29 cents and the ask is 34 cents. The whale’s fill at 15 cents was well below even the current bid, meaning the price has since bounced back above their execution price. Trade flow today is overwhelmingly one-sided: NO buyers account for 97% of contracts traded, with 10,118 NO contracts versus just 327 YES contracts.
What This Market Is
This Kalshi market asks whether the S&P 500 index will be priced above $6,699.99 at exactly 4pm EDT on March 16, 2026. YES contracts pay $1 each if it is; NO contracts pay $1 each if it is not.
The Bottom Line
The whale paid 15 cents per contract — implying 85% odds of NO — but the market has since settled with YES at 29-34 cents, suggesting the broader market sees this as considerably less certain than that fill price implied.
