The market “Will SpaceX Starship Flight Test 13 launch by July 17?” saw a dramatic 75.5 percentage-point drop in its YES contract price over the past 24 hours, falling from 82.0% to 6.5%. This sharp repricing signals a sudden shift in collective market sentiment about the likelihood of the launch happening by the deadline.
Contrary to the steep decline in price, whale trading activity diverged from the trend, with net whale flow showing $15K moved into YES contracts during the same period. Whale buy volume reached $23K, outweighing $8K in sell volume, across 60 unique whales. This indicates that larger traders were accumulating YES positions even as the broader market sharply discounted the probability.
Polymarket’s total 24-hour volume on this market was $21K, nearly matching the lifetime market volume of $22K, highlighting a surge in trading interest around this event. A total of 120 unique traders participated, underscoring broad engagement.
The divergence between whale buying and the price plunge suggests conflicting signals: while the market price reflects growing skepticism about the Starship Flight Test 13 launching by July 17, whales appear to be betting on a rebound or hedging against the sharp move.
