Polymarket priced the chance of Anthropic’s market capitalization finishing between $1.75T and $2.0T at market close on IPO day at 26.5%, down 3.5 probability points over 24 hours, with $436K traded. According to PredictionBubbles, the contract appeared among the downward finance moves on its movers board.
The contract concerns a specific valuation range at the close of Anthropic’s first trading day—not simply whether the company completes an IPO. PredictionBubbles separately identified “Will Anthropic IPO by November 30, 2026?” as a category’s largest mover. The supplied material does not give that contract’s price or the size of its change.
What the board captures
PredictionBubbles aggregates prices from Polymarket and Kalshi and updates its rankings every 15 minutes. The supplied snapshot records venue data collected on 26 Oct 2026, 14:13 UTC; the accompanying story was published Oct 26, 2026 · 10:39 AM ET.
The board ranks changes by their absolute size in probability points over 24 hours, rather than by relative percentage change or trading volume. Its coverage spans 2,003 markets that remain live longer than 14 days, with the displayed table showing the top 150 of 521 markets moving at least one probability point.
The material provides no company announcement, fundraising development or other specific explanation for the Anthropic valuation contract’s decline. The $436K traded supplies activity context, but does not establish the depth of the order book or identify what drove the repricing.
What it means for prediction markets
The signal is range-specific. A lower price for the $1.75T–$2.0T band does not, by itself, show whether traders shifted toward a higher or lower IPO-day valuation.
Timing and valuation are separate questions. The November 30, 2026 IPO contract addresses a different outcome from market capitalization at the IPO-day close.
Movement is not a catalyst. The 3.5-point decline records a change in market pricing; the supplied reporting does not establish its cause.
Volume does not determine rank. PredictionBubbles ranks by probability-point movement, using trading activity as context rather than as a ranking input.
