Iowa's Senate race splits the venues at midday, with Kalshi favouring Hinson and Polymarket favouring Turek

Election insider-trading questions reach their deadline

Kalshi and Polymarket face a deadline today, Election Day, to answer questions about election insider trading under the Warren-Curtis letters, according to the supplied briefing.

The briefing, published Nov 3, 2026 · 11:54 AM ET, shifts attention toward legal and regulatory questions affecting prediction platforms. It identifies no significant new prediction-platform headline in the preceding 30 minutes.

The material does not include the letters, source links or either platform’s answers. It therefore provides no basis to establish whether Kalshi or Polymarket has responded, or what positions either might take.

For prediction-market readers, the distinction is between a scheduled response deadline and a substantive development. The deadline is the focus of this update; the supplied material does not establish any resulting policy change or enforcement action.

What it means for prediction markets

• Responses remain the key unknown: The material identifies answers as due today but does not confirm their submission or contents.
• The scope is limited: Without the letters or platform responses, readers cannot assess the specific requests or their implications for election contracts.
• A deadline is not an outcome: This update alone does not establish changes to trading access, market rules or contract resolution.
