The prediction had two clear components:

1. Trump would focus on running his media company instead of running for president again.
   This did not come true. Trump Media & Technology Group (TMTG), parent of Truth Social, did go public via a SPAC merger with Digital World Acquisition Corp. in March 2024 and now trades under ticker DJT, with Trump as the dominant shareholder. (accessnewswire.com) However, Donald Trump formally announced a 2024 presidential campaign on November 15, 2022, became the Republican Party’s presumptive and then official nominee in 2024, and went on to win the 2024 presidential election. (en.wikipedia.org) He was inaugurated again on January 20, 2025, and is now serving as president, actively shaping GOP strategy for the 2026 midterms. (reuters.com) This directly contradicts the idea that he would choose running the media empire instead of returning to the presidency.

2. If it’s not Biden, the Democratic nominee would be a Biden-aligned proxy rather than a significantly different ideological choice.
   This did come true. President Joe Biden initially ran for re‑election and secured enough delegates, but after a widely criticized June 2024 debate performance he withdrew from the race on July 21, 2024. (en.wikipedia.org) Biden endorsed his vice president, Kamala Harris, who was subsequently chosen as the Democratic nominee on August 5, 2024. (en.wikipedia.org) Harris had served as his VP and ran on a platform broadly continuous with Biden’s, fitting well with the notion of a Biden-aligned proxy.

Because the first, very specific claim (Trump opting for the media company instead of another presidential run) is clearly false, while the conditional second claim about a Biden-aligned proxy nominee is true, the overall combined prediction is best judged as wrong.
