Perplexity AI CEO Aravind Srinivas jokingly posted on X, "Considering raising $500B from USAID. Funding secured. Stop me if you can Elon Musk." His post came as US President Donald Trump and Musk called for shutting down US Agency for International Development (USAID). Notably, Musk in 2018 tweeted he had "funding secured" to take Tesla private at $420 per share.
