Holmes was sentenced to 11 years in prison and three years of supervised release.
Courts can grant release during an appeal if the defendant is not seen as a flight risk or threat to the community,
The court ruled that Holmes had not presented any new evidence to support her request for bail.
Although Holmes is not considered a danger to the community or a flight risk, the court denied her request.
In her appeal, Holmes argued that she did not promote a faulty product, but the court disagreed.
The company attracted nearly $1 billion in investments even though its results were often faulty.
