Polymarket live board at 667 active markets, $4,541.0M total volume, $134.7M traded in 24h and $484.7M liquidity

Polymarket activity snapshot

Polymarket’s live-board snapshot listed 667 active markets, $4,541.0M in total volume, $134.7M traded over 24 hours and $484.7M in liquidity. The figures accompanied an update published Oct 17, 2026 · 1:09 PM ET.

The accompanying news summary described a quiet 15-minute period, with no significant new platform headline found. Search results instead resurfaced items already covered that day, including a Taiwan block. The supplied summary provides no further detail on that item.

Source timing and coverage

According to PredScope Prediction Market Statistics, October 17, 2026, the statistics page draws on Polymarket’s public API and refreshes automatically every 10 minutes. Its stated last update was Oct 17, 2026 at 17:25 UTC.

The source page describes coverage of 675+ active prediction markets, rather than the 667 in the headline snapshot. The supplied material does not explain that difference, and the page excerpt does not independently display the headline’s volume or liquidity totals.

PredScope defines its volume figures as total USDC wagered. It also describes views covering category-level trading activity, the largest probability changes over the last 24 hours, volume distribution across markets and the distribution of leading-outcome probabilities. No individual market readings from those views were supplied.

What it means for prediction markets

• The figures describe platform-wide activity, not directional conviction. Aggregate volume and liquidity alone do not establish which outcomes traders favor.
• The market-count discrepancy matters for comparisons. The headline’s 667 active markets and PredScope’s stated 675+ coverage should not be treated as an identical observation without clarification.
• A quiet news interval does not establish quiet pricing. The summary reports no significant new platform headline over 15 minutes, but the supplied data do not show whether individual contract probabilities moved.
