David Sacks said Trump would not secure the 2024 Republican presidential nomination. In reality, Donald Trump announced his 2024 campaign on November 15, 2022, went on to dominate the Republican primaries, became the presumptive GOP nominee on March 12, 2024, and was then officially nominated as the Republican Party’s 2024 presidential candidate at the Republican National Convention in Milwaukee on July 15, 2024.(en.wikipedia.org)

Since Trump did in fact secure the 2024 Republican nomination, Sacks’s prediction is wrong.
