The claim is an opinion that would need some reformation to become a fact claim. To say that it was "the most streamed match" of 2024 (as you insist in the body of your claim) is verifiable, but otherwise, the claim is opinion-based. The question I would pose is, biggest fight on what metric? Viewership? Cost? Attendance? Stakes? The list goes on and on. Further in the claim, you point out viewership as the metric, but that is not prevalent in the main claim.
In reference to the viewership, Netflix gave a statement about the fight, saying,
"The Jake Paul vs Mike Tyson fight is the most-streamed sporting event ever, peaking at 65 million concurrent streams, with 38 million concurrent streams in the US."
These numbers are impressive compared to the UFC 300 event in April. According to Johny Payne, a writer for Sportskeeda, viewership peaked at a measly 2.49 million for the main event. So, in reference to this being the most-viewed/streamed boxing event of 2024, the claim would be true. Even further, it is the most streamed event in general, beating Disney's stream of the 2023 Cricket World Cup.
