The trial will be considered to have started in a jury trial when the jury is sworn. 

 Crist v. Bretz, 437 U.S. 28 (1978). In a bench trial, the trial will be considered to have started once the first witness is sworn. 

 Serfass v. United States, 420 U.S. 377, 388 (1975). The trial will be considered to be over once a verdict has been rendered on all charges. More specifically, a charge will be deemed to end in an acquittal if "any ruling that the prosecution’s proof is insufficient to establish criminal liability for an offense" is returned by the jury or found by the judge. Evans v. Michigan, 568 U. S. 313, 318 (2013). The case will deemed to end in a conviction once judgment is entered on the verdict of guilty (usually after sentencing). This market will remain open through retrials ordered by the trial court however, it will not remain open if a new trial is ordered on appeal (though if a new trial is ordered after appeal, a duplicate market will likely be created for that trial)

Each answer will be resolved independently based on publicly available court records, media reports, and official trial documentation. Markets will resolve as follows:

The unlikely event of significant ambiguity regarding whether the resolution criteria have been met. I reserve the right to resolve a question to a percentage that I deem fair. I will give notice before I do this.
