Co-founder of Viking Global Investors.

Andreas Halvorsen runs Viking Global Investors LP, a diversified book of 77 stocks worth $35.7B as of Q1 2026 (disclosed May 15, 2026, a ~45-day 13F lag). This quarter they opened Apple Inc and trimmed Taiwan Semiconductor-SP ADR. Their largest long position is Visa Inc-Class A Shares at 5% of the equity book. Cloning the disclosed picks since 2013 would be +366% (+12.8%/yr). That is a simulation of the disclosed long book, not audited returns.

Andreas Halvorsen, Viking Global Investors LP (copied at disclosure) S&P 500

Growth of $10,000 cloning Andreas Halvorsen, Viking Global Investors LP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.

Fund
Long book

Aggregated from SEC Form 13F filings (institutional long equity positions, reported quarterly, up to 45 days after quarter-end). Holdings are public domain, sourced to SEC EDGAR. The book totals, weighting, concentration and sectors are long equity only; disclosed put/call options are listed separately and excluded from those figures. The performance line is a simulation of the disclosed long book, not an audited fund return. Every panel is one call to the Arkolith API & MCP server.
