Viking Global Investors

Ole Andreas Halvorsen founded Viking in October 1999 with Brian T. Olson and David C. Ott, and serves as chief executive and risk manager. Halvorsen trained under Julian Robertson at Tiger Management, making Viking one of the roughly thirty Tiger Cubs, the funds started by managers who began their investment careers inside Robertson's shop. The research method shows the lineage: concentrated, fundamentally driven, long-horizon positions built bottom-up rather than from macro calls.

The firm frames its own approach as a long-term, fundamental, research-based perspective applied globally in pursuit of the highest risk-adjusted returns, and it has built a reputation as a patient holder across both public and private books. Coverage runs out of offices in Stamford, New York, Hong Kong, London and San Francisco.

Viking Global Investors was founded in October 1999 and reports more than $56 billion in assets under management as of June 30, 2026. The trajectory has not been monotonic: the firm managed $59 billion as of March 31, 2021, and in June 2017 returned $8 billion to investors to reset to a smaller size, a rare act of voluntary capital discipline among managers of that scale. The flagship fund reopened to new capital in August 2023 after roughly a decade closed.

Capital is organised into three declared strategies: public equity, private equity through Viking Global Opportunities, and credit and structured capital. The private vehicle is what puts Viking into late-stage venture rounds, typically Series B and later in companies with established revenue and proven unit economics. On the public side the firm disclosed a $526 million position in Boeing in February 2025 alongside expanded financial-sector holdings in Bank of America, Charles Schwab and JPMorgan.
