The rivalry between the world’s leading prediction markets has taken a dramatic turn. Polymarket has initiated an internal investigation and compiled a dossier dubbed “The Imitators,” logging roughly a dozen incidents it deems highly suspicious. The firm has even gone so far as to tint its Manhattan office windows to prevent external monitoring.
A Series of Highly Specific Coincidences
Polymarket claims that Kalshi has been shadowing its marketing campaigns and product launches with unnatural precision. For instance, Polymarket planned a grocery-themed promotional event for February 12, only for Kalshi to launch a highly similar voucher promotion nine days prior.
The sharpest suspicion surrounds the rollout of perpetual futures. Polymarket was scheduled to unveil its take on the product on April 21. Approximately one hour before the official announcement, a tech news outlet reported that Kalshi was preparing its own version.
“There have been a couple too many coincidences. There is bad intention in how they copy us. They’re breathing down our neck,” said Matthew Modabber, head of marketing at Polymarket.
Office Sightlines and Insider Fears
Adding to the tension, venture firm Paradigm, which backs Kalshi, leases an office directly across the street from Polymarket’s SoHo headquarters. Sources claim the office offers clear sightlines into Polymarket’s workspace and employee screens. This setup has led some staff members to privately raise concerns about potential “moles” operating within the firm.
Kalshi and Paradigm Push Back
Both accused entities have firmly rejected the allegations, characterizing them as groundless and defensive maneuvers amid tightening market competition.
“This is sad and borderline delusional. We have been building our perpetuals product since 2024, and the media likely caught wind of it from our public teasers on social media,” countered Kalshi spokesperson Jack Such.
A spokesperson for Paradigm described the physical surveillance concerns as “laughable.” To date, no public evidence of espionage has been brought forward, and the allegations remain unproven.
