Atreides Management, LP

Gavin Baker · Boston, MA · Founded 2019

Atreides Management is a Boston-based investment firm founded in 2019 by Gavin Baker, who serves as Managing Partner and Chief Investment Officer. The firm runs a crossover strategy — investing across both public equities and private companies — concentrated in technology, AI infrastructure, semiconductors, and internet businesses.

Baker spent nearly two decades at Fidelity Investments (1999–2017), most notably running the roughly $17 billion Fidelity OTC Portfolio from 2009 to 2017, where the fund outperformed more than 99% of its Morningstar peers and won six Lipper awards over his tenure. The Boston Globe named him Fund Manager of the Year in 2014. He also helped launch Fidelity's venture-capital investing before leaving to found Atreides.

Atreides files a Form 13F each quarter disclosing its US-listed equity holdings. The tables below cache its four most recent filings; positions in companies R40 tracks are linked to their pages.

How to read these tables. A Form 13F reports each holding's market value as of the quarter-end date and the share count — not the price the fund paid, when it bought, or any short positions. Buys and sells are inferred by comparing share counts across quarters. Put/call lines are options (often hedges), and their value is notional rather than a straight equity stake. Figures are the fund's US-listed 13(f) holdings only; private positions appear when the manager reports them.
