[Kalshi Co-Founder: Open Competition Drives Price Discovery, The Strongest Financial Markets Are Built on the Same Principles of Competition] Odaily Planet Daily News – Prediction market platform Kalshi co-founder Tarek Mansour posted on the X platform, stating that ahead of today's U.S. Open tennis finals, Kalshi placed full-page ads in *The Wall Street Journal*, *The New York Times*, and *The Washington Post*. Using tennis legend Pete Sampras's professional career as an example, Mansour elaborated on his views regarding market competition. Mansour emphasized that open competition exposes weaknesses, rewards effective strategies, and forces participants to continuously improve—just as in financial markets. In trading markets, different participants express their judgments about asset values through capital, with more accurate information being rewarded, ultimately converging diverse opinions into a single market price, thereby driving price discovery. He believes that truly open markets should allow anyone to participate, adhere to the same rules, and maintain transparency in pricing and trading activities.
