Phishing sites copying Kalshi and Polymarket surface ahead of the midterms

Platform impersonation ahead of the midterms

Phishing sites imitating Kalshi and Polymarket have surfaced ahead of the midterms, according to the security item linked to cxotoday.com. The report concerns fraudulent lookalikes of prediction-market platforms, rather than a change to their markets or trading rules.

The item was published on Oct 16, 2026, at 8:39 AM ET. It puts platform impersonation on the election-season security agenda for readers following both venues.

The cxotoday.com page text was unavailable for review. The supplied material does not identify the sites’ operators, describe how the phishing attempts work or establish how many users may have encountered them.

It also provides no details about losses, platform responses or enforcement action. The appearance of imitation sites should not, on its own, be read as evidence that either Kalshi or Polymarket has been breached.

What it means for prediction markets

• The reported risk is impersonation. The available information concerns sites copying Kalshi and Polymarket, not a demonstrated compromise of either platform.
• Market effects remain unestablished. The supplied material provides no evidence of disrupted trading, altered prices or affected settlement.
• Scope is the key unanswered question. Without the source text, the reach of the phishing activity and any response by the platforms cannot be assessed.
