- 01 Sylebra Capital, the mid-cap technology fund run by former Coatue partner Daniel Gibson, holds a $773.7 million U.S. long-equity portfolio per its May 13F filing, built around one move: cut the software and fintech names and hold its hardware bets steady.
- 02 The disclosed U.S. stock portfolio fell from $1.15 billion in December to $773.7 million in March, a 33 percent drop, most of it mark-to-market losses on Impinj and PureCycle rather than selling.
- 03 Five stakes hold about 85 percent of the portfolio: Aeva Technologies at $213.6 million, PureCycle Technologies at $176.9 million, Impinj at $116.3 million, Paycom Software at $83.7 million, and Elastic at $70.5 million.
- 04 The pattern is concentration into hardware conviction: Gibson left his three largest bets, Aeva's laser sensors, Impinj's tracking chips, and PureCycle's recycling, at identical share counts while trimming nearly every software and fintech name around them.
- 05 The next 13F, due by mid-August, will show whether Gibson keeps Aeva and Impinj at identical share counts for another quarter or finally trims his conviction core.
How Sylebra Moved Last Quarter
What to watch
1. Sylebra’s next 13F is due by mid-August 2026. It will show whether the U.S. equity book stabilizes near $774 million or keeps shrinking after losing a third of its value in three months.
2. Aeva, Impinj, and PureCycle each carried the exact same share count in December and March. The next filing will reveal whether Gibson trims or adds to the three bets he has so far left completely alone.
3. The selling hit the software and fintech names hardest, with Nu Holdings down 58 percent and Paycom down 29 percent. Whether those cuts deepen toward full exits is the clearest signal of whether Sylebra is rotating out of software.
