The prediction was that the 2024 U.S. presidential election would feature Ron DeSantis as the Republican nominee and Gavin Newsom as the Democratic nominee.

In reality, the general election held on November 5, 2024 featured Donald Trump as the Republican nominee and Kamala Harris as the Democratic nominee.(en.wikipedia.org) Joe Biden initially ran and became the presumptive Democratic nominee, but he later withdrew in July 2024 and endorsed Harris, who was then formally nominated by the Democratic Party; Newsom was never the nominee.(en.wikipedia.org) On the Republican side, Ron DeSantis ran in the primaries but dropped out after Trump’s dominant performance in early contests, and Trump secured the nomination.(en.wikipedia.org)

Because neither DeSantis nor Newsom was their party’s 2024 presidential nominee, the prediction is wrong.
