This sharp increase in odds was supported by whale activity that moved in tandem with the price shift. Over the same period, whales contributed a net $39K into YES contracts, with $77K in buy volume against $39K in sell volume. The presence of 129 unique whales participating suggests broad engagement from large traders confirming the price move.
