What it is

Thrive Capital is a US venture capital and growth-equity firm headquartered in New York City. It invests primarily in software, consumer internet, financial technology, and artificial intelligence companies, at stages ranging from early venture through late-stage growth. The firm operates a small number of concentrated, high-conviction positions and deliberately maintains a low public profile relative to its scale. As of early 2026, it manages approximately US$50 billion across ten fund vintages. Joshua Kushner, founder and managing partner, also co-founded Oscar Health in 2012 and holds a minority stake in the Miami Heat NBA franchise.

History

Joshua Kushner launched the firm in 2010 at age 24, seeded with roughly US$5 million from General Catalyst co-founder Joel Cutler. The debut institutional fund, raised in 2011, totaled US$40 million. Thrive scaled quickly on the strength of early exits: its Series B investment in Instagram in 2012 doubled within 72 hours when Facebook acquired the company for US$1 billion. Subsequent funds grew from US$150 million (Fund III, 2012) to US$400 million (Fund IV, 2014), US$700 million (Fund V, 2016), and US$1 billion (Fund VI, 2018). The firm backed Spotify, GitHub, Twitch, Stripe, Slack, Plaid, Ramp, Robinhood, and Databricks across those vintages, establishing a consistent pattern of early stakes in consumer and fintech platforms that later commanded large public-market valuations.

Current state

Thrive IX, closed in August 2024 at over US$5 billion (US$4 billion late-stage, US$1 billion early-stage), was at that point the firm's largest fund. Thrive X closed in February 2026 at US$10 billion, pushing cumulative AUM to approximately US$50 billion. OpenAI has been the firm's most prominent recent position: Thrive invested roughly US$130 million in OpenAI in early 2023, led an employee-tender process valuing OpenAI at US$86 billion in early 2024, and committed approximately US$1 billion in a December 2024 round at a US$285 billion valuation, followed by a further US$1 billion at the same valuation in February 2026. In May 2026, Thrive co-led Anduril's US$5 billion Series H alongside Andreessen Horowitz at a US$61 billion valuation, the largest private defense-technology round on record (see アンドゥリルがシリーズH 50億ドルで評価額610億ドルに倍増 and 防衛テックスタートアップが5カ月で146億ドルを調達、2025年の年間記録を塗り替える). In early 2025 Thrive launched Thrive Holdings, a subsidiary that acquires and operates companies it believes can be transformed by AI; in December 2025 OpenAI took an ownership stake in Thrive Holdings, with OpenAI deploying its engineering staff inside portfolio companies and receiving a growing stake as those businesses scale.

Relationships

Thrive's relationship with OpenAI is the most structurally significant in its current portfolio. Thrive is one of OpenAI's largest outside shareholders while OpenAI holds equity in Thrive Holdings, a configuration critics describe as circular: OpenAI's valuation supports Thrive's fund performance, and Thrive's capital supports OpenAI's fundraising. Kushner's family connections add a political dimension: his brother, Jared Kushner, served as a senior adviser to US President Donald Trump in the first administration and leads Affinity Partners, a separate investment firm with Gulf sovereign-wealth backing. That connection has drawn scrutiny over whether Thrive's LP base includes Gulf capital and how family relationships intersect with US technology policy. In the defense space, Thrive is now closely tied to Andreessen Horowitz through the Anduril co-lead, signaling an alliance between the two largest US technology venture platforms on national-security bets.

What to watch

The OpenAI-Thrive Holdings circular deal will face increasing scrutiny from US investors and regulators as OpenAI moves toward a public market listing expected in 2027. Whether limited partners in Thrive's funds consider the arrangement a conflict of interest, and how US SEC review of OpenAI's for-profit conversion addresses entangled investor structures, will shape precedent for the broader AI industry. Thrive X, at US$10 billion, is large enough to require exits of comparable scale, concentrating the firm's fate on a small set of very large bets, chiefly OpenAI. The Anduril position ties Thrive to US Pentagon procurement timelines for the first time at meaningful scale, introducing a long and unpredictable revenue cycle that differs from the firm's historical software playbook.
