The market for “Will OpenAI’s valuation hit (HIGH) $1.0T by December 31?” saw a dramatic shift in sentiment with the YES contract price tumbling 43.5 percentage points over the past 24 hours, dropping from 77.5% to 34.0%. This sharp decline in implied probability contrasts with on-chain whale activity, which shows $2K net inflows into YES positions amid $3K in whale buy volume and $1K in sell volume across 19 unique whales.
This divergence between price action and whale flow signals a split in market conviction. While the tape indicates a substantial sell-off or loss of confidence in the $1.0 trillion valuation scenario, whales have maintained a net buying stance, suggesting some high-net-worth traders see value or a potential rebound.
Polymarket’s YES price currently sits significantly below the Polydata on-chain mid-price of 67.5%, reflecting differing data sources and possibly fragmented market views. Total 24-hour volume on Polymarket reached $7K, with lifetime volume at $51K and 121 unique traders participating, underscoring active engagement despite the recent volatility.
The combined picture of a steep price drop paired with whale accumulation highlights a market in flux, with retail and institutional participants sending contrasting signals about OpenAI’s ability to reach a $1.0 trillion valuation by year-end.
