What Stone Ridge Asset Management does
Stone Ridge Asset Management is a privately held New York-based alternative asset manager founded in 2012 by Ross Stevens that operates a multi-strategy platform of "True Alternatives" investments engineered to deliver returns uncorrelated to traditional stocks and bonds (measured correlation <0.1 since inception across registered reinsurance, alternative lending, fine art, and multi-strategy funds). As of March 31, 2026, the firm manages approximately $35 billion in assets under management across ten franchises: Reinsurance (catastrophe bonds and quota shares — ~$9B of cat bonds purchased and ~$110B of cat limit supported in partnership with leading global reinsurers), Energy (natural gas PDP assets through Stone Ridge Energy, with ~$11B of energy assets purchased and operational control via the 2024-acquired Flywheel Energy subsidiary), Alternative Lending (the LENDX fund with ~9 million individual loans and ~$40B purchased across leading consumer and SMB origination platforms), Single-Family Rentals (~60,000 homes via independent operating platforms), Art (Post-War & Contemporary via Masterworks), Opportunistic, Multi-Strategy, LifeX (longevity-linked income), and Bitcoin (via majority-owned NYDIG subsidiary). Longtail Re, a casualty reinsurer-of-reinsurers launched in 2020, ended 2025 with over $6B in assets and has delivered 20% annualized ROE since inception. The firm invests ~$8B of its own balance sheet, employee, and equity-owner capital alongside clients, with owners/employees owning more than 40% of Longtail Re.
The firm's core technology consists of proprietary databases hand-built over many years — including a catastrophe bond database covering every cat bond ever issued combined with multi-decade reinsurance performance history, and an art auction database covering ~8,000 artists, ~1,500 auction houses, and ~300,000 sales dating back to 1900 — together with proprietary securitization capabilities that have enabled investment-grade ABS issuance on natural gas PDP assets at 200-250 bps over corporate credit. Its go-to-market combines direct enterprise relationship management targeting institutional investors (pension funds, endowments, foundations), insurance companies (with tailor-made structures meeting regulatory and accounting needs), and wealth professionals (through registered mutual funds and tailored education programs). Distribution channels include direct institutional sales globally and wealth-professional distribution domestically, supplemented by the SMArtX Advisory Solutions platform partnership for advisor-channel reach.
