That is enough to make the episode uncomfortable, even before anyone proves anything more. Timing can be observable without the explanation being settled. The Times said it was unclear whether the person had access to inside information or simply made good trades.
The distinction is the whole story. A smart bet is ordinary. A bet placed with nonpublic polling data would be something else entirely. From the summary the Times published, researchers appear to have found a pattern worth flagging, not a completed case.
Two races and two platforms are not a grand theory of corruption. They are, however, a reminder of what makes political betting markets interesting and fragile at the same time: prices react quickly, but outsiders often cannot see why a particular trader moved when they did.
The Times did not establish that inside information was used.
