The Polymarket contract asking whether Israel will launch military action against Greater Beirut by August 31 saw its YES price climb sharply by 19.5 percentage points over the last 24 hours, rising from 46.5% to 66.0% as of July 12.
This significant price move was accompanied by whale trading that aligned with the shift, indicating that large investors were adding net exposure to YES positions in tandem with the market repricing. The total 24-hour volume on the market was $5K, reflecting steady liquidity behind the move.
The combination of a rapid increase in the implied probability and whale flow moving in the same direction suggests a consensus building around the likelihood of military action within the specified timeframe. This alignment of price and large-scale trading activity points to growing conviction among informed traders, rather than a price move driven solely by retail speculation or noise.
As a result, the market now prices the event at two-thirds probability, signaling a notable shift in sentiment and expectations about the geopolitical situation in the region.
