Alyeska Q1 2026: Nvidia Joins $35.38B Book

TL;DR: Alyeska Investment Group's Q1 2026 Form 13F shows a $35.38B reported 13F value that was nearly flat quarter over quarter, but the surface stability hides a sharper rotation: IVV remained the largest disclosed line at $2.76B and 7.80%, while Nvidia entered as a $993.7M position and Micron, Robinhood, Uber and other names joined the top book. The filing was a Form 13F-HR filed 2026-05-15 for reportDate 2026-03-31, accession 0001172661-26-002284.

Alyeska Investment Group, L.P. is best read as an active Chicago multi-strategy hedge fund rather than a passive allocator. Founded by Anand Parekh in 2008, the firm is commonly described as market-neutral and research-driven, so a 13F snapshot captures the long disclosed side of a broader book rather than the entire risk profile.

The central Q1 signal is not asset growth. Reported 13F value moved from $35.40B to $35.38B, a -0.1% change, while disclosed positions rose from 575 to 605. That combination points to portfolio turnover and dispersion: Alyeska kept scale roughly intact, but spread the book across more disclosed securities and reshuffled the largest exposures.

A $35.38B book with IVV cut but still on top

IVV stayed the largest reported position at $2.76B, or 7.80% of the disclosed portfolio, even after a Reduced -33% status. That matters because the ETF line still anchors a book otherwise dominated by single-name equities. Nvidia was the more revealing change: a NEW position at $993.7M and 2.81%, immediately ranking second in the Q1 filing.

Amazon remained a major line at $914.0M and 2.58%, but its Reduced -31% status changes the interpretation. Alyeska did not simply add risk on top of the existing megacap complex. It trimmed IVV and Amazon while making room for new or larger exposures in Nvidia, Micron Technology, Robinhood Markets, CoreWeave and Meta Platforms.

The top 10 concentration is meaningful, not dominant

The top 10 positions accounted for 22.78% of reported 13F value. That is enough concentration to show where the Q1 risk budget clustered, but not enough to make this a single-theme portfolio. The largest tail bucket was still $27.32B and 77.22%, consistent with a multi-strategy manager that can express many smaller ideas alongside a few large anchors.

The top 10 mix also shows a clear blend of beta, AI infrastructure and consumer or platform names. IVV supplies broad market exposure; Nvidia, Micron, CoreWeave, Meta and Amphenol link the filing to AI infrastructure; Robinhood and Uber add platform cyclicality. For readers tracking hedge fund positioning, the notable feature is the barbell: a reduced ETF core, plus several single-name positions large enough to matter individually.

Flat AUM masks a two-year expansion

The Q1 quarter looks stable only if viewed in isolation. Alyeska's reported 13F value was $16.25B in 2024Q1, $26.62B in 2024Q4, $35.40B in 2025Q4 and $35.38B in 2026Q1. The latest quarter paused the climb, but it did not reverse the larger expansion of the disclosed long book.

That history changes the reading of the -0.1% move. A flat total after the 2024Q4, 2025Q2 and 2025Q3 step-ups suggests Q1 was more about internal rotation than balance-sheet contraction. The position count rising to 605 reinforces that point: the filing became broader even as reported value stayed nearly unchanged.

What the Q1 rotation says about Alyeska

Alyeska's Q1 2026 13F looks like a manager rebalancing factor exposure rather than making a simple market call. The IVV reduction lowered the largest ETF line, Amazon was reduced, and new top-tier entries appeared in Nvidia, Micron, Robinhood and Uber. CoreWeave and Meta were not new, but their Increased +75% and Increased +106% statuses put them in the same rotation narrative.

The options-heavy caveat does not dominate this filing because the top disclosed lines shown here are common equity or ETF positions, not puts and calls. Still, the broader hedge fund context matters: 13F reports do not show shorts, many derivatives, cash or intra-quarter trades. For an active multi-strategy manager like Alyeska, the filing is strongest as a map of disclosed long exposure, not a complete measure of net conviction.

Investors using 13F Insight should therefore focus less on the headline AUM and more on the shape of the reshuffle. The article's strongest takeaway is that Alyeska held a $35.38B reported 13F book steady while moving the visible top end toward Nvidia, Micron, CoreWeave, Robinhood and Meta, with IVV still the largest but no longer as dominant as the prior quarter implied.
