“The U.S. AI sector is on track to require at least 50 gigawatts of electric capacity by 2028, much of which will be needed to train the world's most capable models: we project that 2GW and 5GW data centers will be needed to develop single advanced AI models for Anthropic in 2027 and 2028, respectively, and we expect total frontier AI training demands in America to reach 20-25GW in total by 2028.”

Anthropic has since repeated the 50GW figure in later announcements ('the US AI sector will need at least 50 gigawatts of capacity over the next several years'); the 2028 deadline has not arrived.
