Mysterious whales have made $2.1B worth trades in a single month

Anonymous “whales” placed massive sell orders in Brent crude futures—roughly $2.6 billion combined ($500M in March, ~$2.1B in April)—consistently moments before major U.S. announcements related to the Israel‑Iran conflict, driving oil sharply lower (Brent fell from $100.91 to $96.83 within minutes on April 22). The timing and scale prompted lawmakers and the CFTC to probe trading activity and request exchange data from CME and ICE; regulators are also being urged to review suspicious bets on prediction markets like Polymarket. The story notes a contrast with crypto markets where large Bitcoin transfers are more traceable on‑chain, spotlighting market‑moving whale behavior, potential informational advantages, and regulatory scrutiny that could affect liquidity and timing risk across futures and crypto markets.
