#TrumpVsMusk refers to recent debates, tensions, or rivalries — real or perceived — between former US President Donald Trump and billionaire entrepreneur Elon Musk. The hashtag has been used on social media to comment:

Politics and freedom of speech: Musk, owner of X (formerly Twitter), has promoted a discourse of unrestricted freedom on the platform. Trump, after being banned and then readmitted, criticizes some moderation decisions and Musk's stances.

Business and influence: Both are vying for influence in the political and technological landscape of the US. Musk tries to maintain an image of an independent innovator, while Trump seeks to reaffirm his political and media power.

Personal issues and public attacks: Occasionally, the two exchange barbs, with Trump calling Musk a "publicity artist" and Musk criticizing Trump for political actions or controversial statements.

Electoral context (2024-2025): The hashtag gained traction with the approach of the 2024 presidential elections. Musk has not officially declared support for Trump, which has generated more speculation and friction between the two figures.
