Kalshi CEO Tarek Mansour Says the Real Choice Is U.S. Prediction Markets or Offshore Ones

Introduction

At DC FinTech Week, Kalshi chief executive Tarek Mansour framed the ongoing regulatory debate as a binary choice: keep prediction markets under U.S. oversight or see the industry shift abroad. His remarks came on the heels of two recent moves by the Commodity Futures Trading Commission (CFTC) to codify event contracts—covering sports, politics, culture and weather—as swaps, while carving out exemptions for traditional sportsbook wagers and casino games. The stakes are high for platforms like Kalshi, which are navigating a patchwork of federal and state rulings.

The regulatory crossroads

The CFTC’s October 9 proposal would formally bring a broad class of event contracts within the agency’s exclusive jurisdiction under the Commodity Exchange Act. Chairman Michael S. Selig emphasized that these contracts are “commodity derivatives squarely within the CFTC’s regulatory remit.” At the same time, federal appeals courts have issued conflicting decisions: one ruling favored Kalshi’s national approach, while two upheld state authority over such markets. New Jersey has petitioned the Supreme Court, and the NFL has filed an amicus brief supporting the states’ position. Mansour stressed that the outcome will decide whether prediction markets operate domestically at all, rather than simply determining the level of government that regulates them.

Transparency as both blessing and curse

Mansour also highlighted the public nature of prediction‑market trading as a double‑edged sword. He argued that open order books make illicit activity easier to spot and prosecute. Citing the recent insider‑trading case involving former congressman George Santos, Mansour noted that Kalshi received a flood of whistleblower tips within minutes of the alleged misconduct. The CFTC’s own enforcement action against Santos resulted in disgorgement, a civil penalty, and a three‑year trading ban. A separate case involving a former White House teleprompter operator, Gabriel Perez, likewise demonstrated how early‑access information can be abused, leading to a settlement that included significant disgorgement and a ban.

Market‑level safeguards and industry response

In response to heightened scrutiny, both Kalvari and Polymarket have introduced insider‑trading controls designed to flag suspicious activity. Mansour dismissed social‑media claims that Kalshi’s bitcoin and ether perpetual‑futures volumes were artificially inflated, explaining that the observed trade sizes stem from fixed‑size orders placed by market makers. He underscored that these mechanisms, combined with the transparency of public order flow, help regulators and platforms alike detect and deter manipulation.

Looking ahead

The CFTC’s proposed rules are now open for public comment for 30 days, offering stakeholders a chance to shape the final regulatory framework. As the industry watches the Supreme Court’s potential involvement, the central question remains: will a cohesive U.S. regulatory regime keep prediction markets thriving at home, or will the uncertainty push innovators offshore? Mansour’s message is clear—transparent, well‑regulated markets can both protect participants and expose wrongdoing, but the ultimate decision rests with policymakers.
