The probability that SpaceX Starship Flight Test 13 will launch by July 23 dropped sharply by 54.0 percentage points over the past 24 hours on Polymarket, falling from 86.5% to 32.5%.
This dramatic repricing occurred alongside $12K in 24-hour volume, reflecting active trading interest. However, whale activity diverged from the price move: rather than supporting the lower odds, whales reduced their net exposure to YES contracts. This flow divergence suggests that large traders were not aligning with the market’s rapid downward adjustment in launch probability.
The contrasting signals between the price and whale flow highlight uncertainty or disagreement among informed market participants about the likelihood of the Starship Flight Test 13 launch happening by the target date. The sizable drop in the YES price marks a significant shift in market consensus, but the whale behavior indicates caution or skepticism about the new odds.
Combined, the price plunge and opposing whale flow suggest a contested reassessment of the launch timeline, with retail and smaller traders pushing odds lower while whales hold back.
