The market on whether SpaceX Starship Flight Test 13 will launch by July 23 saw a dramatic shift in the last 24 hours, with the YES contract price plunging 64.5 percentage points from 86.5% to 22.0%.
Despite this steep drop in price, whale activity diverged from the direction of the market. Large traders did not follow the sell-off, indicating a disconnect between big-money flow and the rapid repricing. The divergence suggests that while retail or smaller traders pushed the odds sharply lower, whales either refrained from selling YES contracts or potentially accumulated them, signaling differing views on the launch’s likelihood.
Polymarket recorded $12K in volume over this period, reflecting moderate trading interest amid the volatility.
This repricing and flow pattern underlines uncertainty or new information affecting market sentiment, with large traders potentially holding a more optimistic stance than the broader market pricing implies. The gap between price and whale activity will be critical to watch as the July 23 deadline approaches.
