YouTube star MrBeast posted an old video to X and earned over $250,000 from the platform's new ad revenue-sharing program. X owner Elon Musk launched the program to encourage high-quality content and pay creators a share of ad revenue. MrBeast's video received over 160 million views on X, indicating strong engagement. He said advertisers likely bought ads on his video due to the attention, and his earnings may not reflect typical experiences. MrBeast plans to give the $250,000 away but hasn't committed to further X posts due to his videos' high production costs.
