Microsoft (NASDAQ: MSFT) co-founder Bill Gates has long been a proponent of environmental initiatives and a sustainable future. However, according to Walter Isaacson's 2023 biography of Elon Musk, Gates' alleged undisclosed short position against Tesla (NASDAQ: TSLA) led Musk to view his actions as hypocritical.
A short position is simply betting against the company, and investors profit when share prices drop. Isaacson's book highlighted that Gates' bet against Tesla reportedly resulted in a $1.5 billion (£1.17 billion) loss for him as share prices jumped by over 61% year-to-date and 1,578% in the past five years to close at $400.99 (£314.03) on 10th December.
