The market on whether SpaceX Starship Flight Test 13 will launch by July 17 saw a dramatic reversal, with the YES contract plummeting 76.0 percentage points in the last 24 hours, falling from approximately 82.0% to just 6.0%.
This sudden price collapse signals a drastic shift in market sentiment about the launch occurring on schedule. However, whale trading activity diverged from the price move: large traders collectively bought $19K in YES contracts while selling only $6K, resulting in a net $13K inflow into YES positions. This contrasts with the price action, which moved sharply against YES holders.
Fifty-seven unique whales were active in the last day, contributing to a total 24-hour Polymarket volume of $19K on this question, nearly matching the lifetime market volume of $20K. Across the entire market lifespan, 110 unique traders have participated.
The divergence between whale flow and price suggests that while the broader market rapidly downgraded the likelihood of the launch, some large traders maintained or increased exposure to YES.
Overall, the combined data points to a volatile and contested market outlook on the July 17 Starship launch, with whales not fully aligning with the prevailing downward price momentum.
