CFTC chief flags review of oil trades and closer watch on prediction markets

Published Oct 23, 2026
Share:
Summary:
  • CFTC Chairman Michael Selig said the agency takes market oversight "very seriously" and its enforcement division has been looking into oil trading during the Iran war since March 23.
  • Bloomberg said that morning saw a rapid two-minute burst in which traders offloaded contracts tied to Brent and WTI totaling at least 6 million barrels, exceeding the usual volume at that time a week earlier by more than 8.5 times.
  • Selig noted the CFTC is watching prediction markets ahead of the US mid-term elections for any signs of manipulation, and said he was "very disappointed" that lawmakers failed to pass the crypto-focused Clarity Act.

What the CFTC is watching

Speaking on Bloomberg Television, Michael Selig said, "Our enforcement division has been looking at all these trades," adding, "We take this stuff very seriously." He said the review began March 23 and centers on oil-market activity during the Iran war.

He also offered a reassurance on supervision: "We are on top of this and, rest assured, people can have confidence in the markets as long as I'm in the seat."

Why March 23 stands out

Trading surged shortly before President Donald Trump reversed course on threats to strike Iranian power plants. Bloomberg noted that during a two-minute span on the morning of March 23, traders unloaded contracts linked to Brent and West Texas Intermediate amounting to at least 6 million barrels, more than 8.5 times the volume typically observed at that time the week before.

More generally, oil volumes swelled at notable points this spring before some of Trump's announcements, fueling concerns that non-public information may have been used to place timely bets.

Elections, prediction markets and crypto law

Outside the oil probe, Selig said the agency is scrutinizing prediction markets for possible manipulation in the run-up to the US mid-term elections. He added that he was "very disappointed" that US lawmakers failed to pass the new crypto statute called the Clarity Act.

What it means for your portfolio

The CFTC's attention on oil trades and election-linked markets signals more eyes on timing around policy headlines. The bottom line: when oversight tightens, liquidity and volatility can shift, and trading that clusters around big announcements tends to draw scrutiny.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • The most common mistake is treating the letter as an instruction. An A tells you a stock scores well for one goal, not that you should buy today.
  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
