Elon Musk's announcement of the 'America Party' led to a dramatic price surge in a related meme coin, which initially soared by 120%. However, the coin's value quickly plummeted by 89%, underscoring the extreme volatility often associated with meme coins. Musk's criticism of Trump's $3.3 trillion bill and the concept of a 'uniparty' were central to the announcement, which significantly influenced market sentiment and the coin's rapid price movements.
