Jim Simons (1938–2024) was a mathematician and investor who founded Renaissance Technologies and brought mathematical modeling to investment management. This page shows Renaissance Technologies' quarterly Form 13F report of certain United States listed long positions, not Simons's personal account, the Medallion Fund, or the firm's complete investment activity.
Profile refreshed July 20, 2026
As of the Q1 2026 filing, Jim Simons's largest disclosed holdings are United Therapeutics Corporation (UTHR), Palantir Technologies Inc. (PLTR), Apple Inc. (AAPL). The table shows 15 of 3,213 positions by default, with an exact-count control for the remaining rows. Disclosed shares and values remain visible even when a separate market-price estimate is unavailable.
The biggest disclosed buys in Q1 2026 were Apple Inc. (AAPL), NVIDIA Corporation (NVDA), Broadcom Inc. (AVGO), based on the Renaissance Technologies LLC 13F filing. New positions are marked "new" in the table above.
The biggest reductions in Q1 2026 were Costco Wholesale Corporation (COST), Netflix, Inc. (NFLX), Tesla, Inc. (TSLA). The filing comparison contains 358 full exits, summarized in the activity view above.
The latest 13F discloses $63.9B across 3,213 positions in Q1 2026. 13F filings cover US-listed long positions only; cash and short positions are not disclosed.
Funds file 13Fs up to 45 days after each quarter ends, so this portfolio reflects Q1 2026, the latest disclosed quarter. The filing date is shown with every table.
Non-rejected, non-superseded SEC Form 13F filings for Renaissance Technologies LLC provide the Q1 2026 holdings, disclosed values, and filing date shown here. WhoBought prefers filings whose value units validate and labels a sparse filing when validation is unavailable. Industry labels come from the local company classification record.
Performance uses daily closing prices for holdings with available market-price history. It covers the priced share of disclosed value (65%); holdings without sufficient price history are excluded from the calculation.
Jim Simons was an American mathematician, investor, and philanthropist who founded Renaissance Technologies. He lived from 1938 to 2024.
Simons died in New York City on May 10, 2024, at age 86. Renaissance Technologies continues as a firm; this page tracks the firm's filings, not a portfolio he still managed.
He completed a mathematics degree at MIT in 1958 and earned a PhD from the University of California, Berkeley, in 1961, when he was 23.
Simons worked in geometry and topology and, with Shiing-Shen Chern, developed ideas now associated with Chern-Simons theory. His research later became important in mathematical physics.
Yes. He worked on codebreaking for the National Security Agency in 1964 and then joined the Institute for Defense Analyses, while also teaching mathematics at MIT and Harvard.
He first founded an investment firm called Monemetrics, then renamed it Renaissance Technologies. The firm developed trading models from market data and launched the Medallion Fund in 1988.
Simons built teams of mathematicians and scientists to search market data for patterns. Renaissance used mathematical models and algorithms rather than relying mainly on conventional stock-picking judgments.
Wikipedia reports an average annual return of 66.1 percent before fees and 39.1 percent after fees from 1988 through 2018. Those are historical Medallion figures, not the return of the 13F holdings displayed here.
No. Medallion is closed to outside investors. Simons retired at the start of 2010 and remained Renaissance's nonexecutive chairman afterward.
Neither. The holdings table shows Renaissance Technologies' latest Form 13F disclosure, while the quarterly-changes view shows how those reported positions moved. A 13F does not reveal the firm's full quantitative strategy, shorts, or every Medallion trade.
