Polymarket believes archrival Kalshi is spying on NYC offices, staff

Polymarket, a rapidly growing prediction-markets app, is currently investigating a possible case of corporate espionage by its competitor Kalshi. The New York-based platform, led by CEO Shayne Coplan, has compiled a dossier outlining several incidents where Kalshi allegedly launched products similar to Polymarket’s with suspicious timing.

Matthew Modabber, Polymarket’s head of marketing, confirmed the probe, expressing concerns about the similarities between the two companies’ offerings. The investigation is looking into the possibility of moles within Polymarket’s offices and even potential spying by Paradigm, a venture-capital firm that backs Kalshi.

Both Polymarket and Kalshi have been involved in instances where one company appeared to imitate the other. For example, Kalshi’s launch of a free-grocery event in New York shortly before Polymarket’s planned grocery store pop-up raised eyebrows among Polymarket insiders.

The tension between the two companies has escalated as they both face regulatory scrutiny and increased investment. Polymarket has raised $2 billion since its inception in 2020, aiming for a $15 billion valuation, while Kalshi, launched in 2018, has raised $2.6 billion and was recently valued at $22 billion.

While the feud between Polymarket and Kalshi continues, the focus remains on uncovering the truth behind the alleged corporate espionage and maintaining a competitive edge in the prediction-markets industry.
