Viking Global, led by Andreas Halvorsen, has completely divested its significant position in railroad operator CSX Corp. According to regulatory filings, the firm sold its entire stake of 18.68 million shares, which was previously valued at approximately $766.73 million.

This disclosure comes from a 13F filing, a quarterly report required by the SEC, and reflects the firm's holdings as of June 30, 2026. These filings are released with a delay, so the actual trades could have occurred at any point during the second quarter. The exit removes what was a 2.14% portfolio weight for the prominent investment firm.
