ToplineHedge fund billionaire Stanley Druckenmiller acknowledged his Wall Street Journal op-ed criticizing Treasury Secretary Scott Bessent's bond buyback expansion was written with artificial intelligence, validating users on social media who raised questions about the letter.Stanley Druckenmiller, chairman and chief executive officer of Duquesne Family Office, during the Bloomberg Invest event in New York, US, on Wednesday, June 7, 2023.Jeenah Moon/BloombergKey FactsDruckenmiller, who once worked with Bessent under George Soros, said Bessent’s policy to double the maximum size of government bond repurchases to $4 billion per operation was "price management — and a mistake.”The billionaire’s op-ed sparked criticism from social media users who accused it of being AI-generated, citing an AI-detection tool called Pangram that called the letter 100% artificial intelligence.Druckenmiller told NOTUS “of course I used AI,” adding, “I'm not embarrassed by it … I write everything using AI now for the same reason I use a calculator when I do math problems.”Druckenmiller compared the buyback expansion to a "credible fiscal package," writing, "Governments defending prices against fundamentals always lose."The expansion was announced on Aug. 19 and triggered a slump in yields on long-dated bonds, which returned to their original levels the following afternoon—movement Druckenmiller cited as the market's swift rejection of the policy.Forbes ValuationWe estimate Druckenmiller’s net worth at $7.8 billion as of Tuesday, a fortune that has grown 66% since 2020.TangentIt is unclear whether the Wall Street Journal has a policy on AI-assisted submissions from outside contributors. The news outlet says it uses AI for “complex data-driven investigations, to summarize articles, to translate some content into local languages and to power website features,” noting, “Work that includes AI inputs is reviewed by a journalist before publishing.”Key BackgroundDruckenmiller worked with Bessent in the 1990s at Soros Fund Management and has been characterized as the treasury secretary’s “former mentor.” The Treasury Department cited “consistent strong sponsorship from market participants” as the reason for expanding buybacks, though Druckenmiller has instead argued such sponsorship “is the definition of a healthy market.” The Treasury Department will ramp up purchases of older securities beginning Sept. 10 in an effort to increase demand for long-duration bonds and decrease yields. Druckenmiller believes high yields act as a natural warning sign for high debt and rising budget deficits.
