The Polymarket market “Will OpenAI’s valuation hit (HIGH) $1.0T by December 31?” saw its YES contract price fall sharply by 20.5 percentage points over the past 24 hours, dropping from an estimated 76.5% to 56.0%. This significant repricing indicates a marked shift in market sentiment about the likelihood of OpenAI reaching a $1 trillion valuation by year-end.
Contrary to the downward price move, whale activity over the same period diverged from the tape: net whale flow into YES was $3K, with $5K in buy volume against $2K in sell volume, spread across 26 unique whales. This divergence suggests that while the broader market reduced optimism, some large traders maintained or increased exposure to the YES side.
Total 24-hour volume on Polymarket for this question was $9K, contributing to a lifetime market volume of $53K with 131 unique traders participating so far. Notably, Polydata’s on-chain mid-price overview differs from the Polymarket YES price, showing 48.0% versus the current 56.0%, indicating some price discrepancies between sources.
The combination of a steep price drop and continued whale buying signals a complex dynamic: retail and smaller traders appear to be pulling back on the $1.0 trillion valuation scenario, while some whales still see value or hedging opportunities on the YES side.
