Thrive Capital, led by Joshua Kushner, reveals a $215 million investment in Amazon.

      Joshua Kushner's Thrive Capital has acquired approximately $215 million worth of Amazon shares, as revealed in a regulatory filing on Friday. This announcement coincides with a week when the firm informed investors about selling part of its stake in OpenAI, a company in which Amazon currently holds nearly 5%.

      The purchase was detailed in a regulatory document on Friday, but Thrive chose not to comment, and Amazon did not respond to a request for comment. The timing is somewhat awkward for a clear interpretation, as Thrive's first official investor letter, sent just days earlier, indicated the firm is divesting a portion of its OpenAI investment, which has become a significant aspect of its portfolio.

      Amazon recently became a stakeholder in OpenAI after completing a $50 billion investment this month, acquiring nearly 5% in the company ahead of its anticipated public listing. When viewed together, these actions appear less like a new investment and more like a repositioning, as Thrive is shifting from an illiquid private investment to a liquid public stake that includes a portion of the same asset.

      Amazon is also heavily involved elsewhere, having repeatedly funded Anthropic, agreeing to invest up to an additional $25 billion in April, while recording a $16.8 billion unrealized gain on that investment within a single quarter.

      Underlying both of these scenarios is the necessary computational infrastructure. Amazon Web Services (AWS) provides much of the technology that these model companies rely on, which represents what a shareholder is actually investing in. The market has responded positively, with Amazon's market value surpassing $3 trillion this month, making it the fifth company to reach that milestone.

      This move is part of a broader strategy, as Thrive invested around $100 million in Shopify earlier this year, attributing it to AI growth in e-commerce, and its public portfolio already includes holdings in Figma, StubHub, and Oscar Health, the insurer co-founded by Kushner.

      Kushner articulated this strategy himself: “Many of our growth-stage companies compete with, partner with, or become the next generation of public technology companies,” he stated. “The more precise our understanding of public markets, the better our judgment will be in private markets.”

      This is a sound rationale, and it also reflects the venture firm’s activities in filing 13Fs. The lines between supporting private enterprises and engaging in public market trading are becoming increasingly blurred, and Thrive is at least operating in a transparent manner for observers.
