A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

the Commodity Futures Trading Commission announced this matter on May 6, 2026 as release 9227-26. The respondent named is Sidney Lebental (1 individual, 0 entities).

This library tags the matter as spoofing, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.

The order finds Lebental spoofed CBOT Treasury futures on about 50 occasions in 2019 to help genuine cash Treasury orders execute, with a $200,000 penalty and one-month trading ban.

The conduct is recorded against futures, with CBOT identified in the release.

The relief recorded in our data is a civil monetary penalty of $200,000. Penalty and disgorgement are distinct: disgorgement returns the gain, while the penalty is punitive. We store them separately so that aggregate figures across the library are not double-counted.

For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.
