CFTC Opens Three Insider Trading Probes Into Polymarket

—First probe approved in early May: a trader made $300,000 on a pardon prediction
—Second over Iran contracts: accounts with a 98% win rate made $2.4 million
—Third over Google's 2025 rankings; SDNY is conducting a parallel investigation
—Polymarket returned to the U.S. in late 2025 after acquiring QCEX and under CFTC oversight

Why it matters: The scrutiny tests the CFTC's new oversight model for Polymarket less than a year after its return to the U.S. market.
