Kalshi Co-founder: Open competition drives price discovery; the strongest financial markets are built on the same competitive principles.

TechFlow reported that on September 14, Tarek Mansour, co-founder of prediction market platform Kalshi, stated that ahead of the US Open final, his team ran full-page advertisements in The Wall Street Journal, The New York Times, and The Washington Post emphasizing that “competition makes things better.” Citing the career of five-time US Open champion Pete Sampras, he explained that truly open competition exposes weaknesses, rewards effective strategies, and drives continuous improvement among participants.

Mansour further noted that robust financial markets are similarly grounded in the principles of open competition: anyone can participate, all follow identical rules, prices and trading activity remain transparent, and participants should not be constrained by their success. He argued that traders commit capital based on diverse information and viewpoints, and this competitive process fuels price discovery, turning market prices into a real-time signal of collective expectations.
