On September 9, Elon Musk posted on X that "AI+robots will more than double the global economy in less than 10 years." According to IMF projections, global GDP is estimated at $126 trillion in 2026, meaning Musk's forecast implies an additional $126 trillion in annual output by the mid-2030s. This would require an annual growth rate of 7.2% to 9%, significantly higher than the IMF's current projections of 3.0% for 2026 and 3.4% for 2027. Musk also stated that there will be at least one billion robots within a decade, each producing at least five times the output of a human, but warned of a 15-gigawatt power shortfall by 2027 due to surging AI chip production.
