Warren Buffett has quietly scored one of 2025's biggest wins, and it didn't come from tech or AI. Instead, the Oracle of Omaha's fortune swelled by nearly $900 million this year thanks to his long-standing bet on Moody's Corp. (NYSE:MCO). Shares of the credit-ratings giant have climbed from $473 at the start of the year to $509 today, a seemingly modest 7.6% gain that turned into a massive payday given Buffett's 24.7 million-share stake.
