Peter Thiel's Thiel Macro dumped its entire $67.5 million Nvidia position in the fourth quarter of 2024, according to 13F filings released this week. Paul Tudor Jones's Tudor Investment Corp reduced its Nvidia stake by 42 percent, trimming roughly $73 million in market value over the same period. Both firms also exited or materially reduced exposure to MicroStrategy, the leveraged Bitcoin proxy that had returned 467 percent in 2024 before its late-year volatility spike.
The moves were not isolated. Stanley Druckenmiller's Duquesne Family Office pared Nvidia by 22 percent in Q4, while Ken Griffin's Citadel LLC reduced its position by 8 percent—still modest but notable given Citadel's typical index-replication discipline. Thiel Macro held zero shares of MicroStrategy at year-end after carrying a $4.1 million position in Q3. Tudor likewise exited completely. The timing coincided with Nvidia's 12 percent drawdown in December and MicroStrategy's intra-quarter swing from all-time highs near $540 to a close below $330.
What matters is the class of seller. Thiel Macro and Tudor are macro discretionary shops—they do not exit growth positions because of valuation alone. They exit when the trade structure changes. Nvidia's Q4 price action reflected both DeepSeek inference cost revelations and early signals that hyperscaler capital expenditure growth would decelerate from 53 percent year-over-year in 2024 to mid-twenties in 2025. MicroStrategy's unwind followed margin calls during Bitcoin's late-November dip and preceded Michael Saylor's January equity raise, which diluted per-share Bitcoin exposure by 7 percent. These are not sector rotations. These are structural reassessments by operators who sized into AI and crypto as asymmetric momentum plays and found the asymmetry exhausted.
The second-order effect runs through volatility surface and options flow. Nvidia's January implied volatility collapsed 18 vol points from December peaks as systematic CTAs and dispersion traders unwound hedges. MicroStrategy options volume fell 31 percent week-over-week in the first half of February, signaling that speculative premium dried up after the institutional bid disappeared. The unwind was quiet—no single-day capitulation, no VIX spike—but the convexity that drove both names higher in 2023 and 2024 is no longer being systematically refreshed. Family offices and endowments that followed macro hedge funds into these positions now face mark-to-market without the liquidity cushion those funds provided on the way up.
Watch Nvidia's April earnings call for any commentary on inference workload mix and forward capital intensity guidance from Azure, AWS, and Google Cloud. MicroStrategy reports Q1 results in late April; the per-share Bitcoin metric and any additional equity raises will clarify whether Saylor can maintain the premium to net asset value that justified the stock's 3.2x multiple to underlying Bitcoin holdings. Meanwhile, 13F filings for Q1 2025—due by mid-May—will show whether this was a Q4 tax-loss harvest and rebalance or the start of a broader de-risking cycle among discretionary allocators.
Thiel Macro's exit was complete. Tudor's was not. The difference tells you which firm thinks the trade is over and which thinks it merely got expensive.
