U.S. politician scores 163% on suspicious Bitcoin stock trade

A U.S. Congressman has booked extraordinary gains on a little-known Bitcoin mining stock, raising eyebrows in Washington and on Wall Street.

Representative Cleo Fields (D-Louisiana) recently bought shares of IREN Limited (NASDAQ: IREN), a Bitcoin mining company, on July 10, 2025

In a filing disclosed on August 6, Fields reported purchasing between $15,001 and $50,000 worth of IREN stock.

According to disclosures tracked by Finbold Signals, this was the first time any sitting member of Congress had reported a trade in IREN.

Since then, the move has paid off handsomely. At Tuesday’s close, IREN was up 163% from the date of Fields’ trade. The stock added another 6% today alone, extending what has become one of the sharpest rallies in the crypto mining sector this year.

Bitcoin miners in particular have been volatile in 2025, tracking spot Bitcoin’s recovery toward all-time highs and optimism around U.S. crypto ETF approvals.
