Ethereum dip to $2,100 in October priced at 18.5% on Polymarket, down 11 points, on $320K traded

Ethereum’s Polymarket contract asking whether it will dip to $2,100 in October was priced at 18.5%, down 11 probability points over 24 hours, with $320K traded. According to PredictionBubbles’ movers board, the contract was among the largest downward moves in crypto.

The figures accompany an Oct 19, 2026 update published at 5:54 PM ET. PredictionBubbles says its underlying venue snapshot was taken on 19 Oct 2026 at 21:45 UTC, with the board refreshed every 15 minutes.

A lower price for October downside

The decline reflects a reduced market-implied probability of Ethereum reaching the contract’s $2,100 downside threshold in October. It is a change in the price of that outcome, not a measure of Ethereum’s spot-price performance.

The supplied material does not identify a catalyst for the repricing or provide the contract’s detailed settlement rules. The $320K traded supplies activity context, but does not by itself establish the depth of available liquidity.

How the move is measured

According to PredictionBubbles, the board compares Polymarket and Kalshi contracts by the magnitude of their 24-hour probability-point changes, rather than relative percentage changes. Trading volume and liquidity do not determine a contract’s ranking.

The snapshot covered 2,034 markets with lifespans longer than 14 days. Only open contracts with a valid 24-hour comparison qualify; the main table displayed the top 150 of 515 markets that had moved at least one probability point. Those filters mean the Ethereum listing represents a move within a selected universe, rather than every contract on either venue.

What it means for prediction markets

• Less downside priced in: The 18.5% reading indicates a lower market-implied probability of the specified October dip, not certainty that Ethereum will avoid it.
• Points, not percent: The 11-point decline measures the change in the contract’s implied probability—not an 11% fall in Ethereum.
• Activity is separate from depth: The $320K traded adds context, but the supplied material does not show how much liquidity was available at quoted prices.
• A time-specific snapshot: The board updates every 15 minutes, so the reported probability and ranking describe that observation rather than a fixed outlook.
