Billionaire hedge fund manager Paul Tudor Jones, the founder of Tudor Investment, recently made a major change to his firm’s portfolio in the second quarter of 2025. According to the latest 13F filing, he exited the entire stake in Palantir (PLTR) and bought shares of Rigetti Computing (RGTI). This signals a potential shift in focus from the current AI boom to the emerging quantum technology sector.

Jones is famous for predicting the 1987 Black Monday crash and is closely watched by investors.
According to the filings, Jones sold all 175,212 shares of Palantir in the last quarter. In the same period, the fund acquired 905,700 shares of Rigetti.
Why Did Jones Walk Away from Palantir?
Palantir has successfully transformed itself from a government contractor into a highly profitable software company, serving sectors from defense to finance. Its artificial intelligence platform (AIP) has driven strong enterprise adoption and stock gains over the past year.
Jones’ exit suggests he believes Palantir’s valuation may be peaking. The move aligns with his macro-driven approach, which includes taking profits and investing in cheaper, high-potential opportunities.
Betting Big on Rigetti
Rigetti is a high-risk, high-reward play in the quantum computing space. The company is still in the early stages of commercialization.
According to a report by McKinsey & Company, the quantum computing market could be worth as much as $97 billion by 2035. Thus, Jones might be seeing long-term potential in RGTI stock despite it having soared over 200% so far in 2025.
Jones’ position consists of both call and put options, reflecting a hedged strategy that limits downside while still allowing for upside potential.
Which Stock Is Better, PLTR or RGTI?
Turning to Wall Street, analysts are bullish on Rigetti stock and neutral on Palantir. On TipRanks, RGTI has a Strong Buy consensus rating, while Palantir has a Hold rating.
