Joshua Kushner’s Thrive Capital has sent its first formal letter to investors, and the standout figure captures the AI era in miniature.
One of its funds has swelled to about $3.7bn in value, driven overwhelmingly by early bets on OpenAI and SpaceX. The letter, reported by Bloomberg, reads as a victory lap and a quiet hedge at the same time.
That Thrive is writing to its backers at all is notable in itself. Kushner has built one of the most secretive and sought-after firms in venture capital, so a formal letter, complete with hard marks and a candid line on concentration, is a departure that doubles as a statement of confidence.
It also lands at a moment when the whole industry is arguing about whether AI valuations reflect real value or collective hope, which makes a firm this exposed to a single name showing its workings all the more striking.
Thrive’s OpenAI position is practically a chronicle of the boom. The firm first backed the company in 2022 at a $29bn valuation, led a tender the following year at $86bn, and has since committed around a billion dollars more across rounds that valued OpenAI at $150bn and then $285bn.
