The Polymarket contract on whether SpaceX Starship Flight Test 13 will launch by July 17 saw a dramatic shift in the last 24 hours, with the YES price plunging 80.8 percentage points from 81.5% to 0.65%. This sharp repricing occurred despite whale investors net buying $24K worth of YES contracts during the same period.
Whale activity showed $35K in buy volume against $12K in sell volume from 76 unique whales, indicating sustained interest on the YES side. However, the price movement diverged from this flow, as the market dramatically discounted the likelihood of the launch. Total 24-hour volume on the market was $35K, nearly matching the lifetime volume of $36K, and 150 unique traders have participated overall.
This divergence between whale buying and the price collapse suggests conflicting signals in the market. While large traders added exposure to YES contracts, the broader market sharply reduced odds, possibly reflecting new information or shifting sentiment around the feasibility of the launch by the deadline.
The combined picture of steep price decline alongside whale buying points to unsettled expectations and potential volatility ahead in this SpaceX Starship launch market.
