Who Is Buying Zoom? Hedge Fund Activity in 2026
Zoom Video Communications, the company that became synonymous with remote work during the pandemic era, continues to evolve its identity in 2026. Once a $160+ stock riding the wave of work-from-home, Zoom has reinvented itself as an AI-first communications platform, pushing hard into Zoom AI Companion, contact center solutions, and enterprise collaboration tools. But the transition from pandemic darling to sustainable enterprise platform has been anything but smooth, and the institutional positioning data tells a powerful story.
The latest 13F filings reveal a sharply divided hedge fund landscape: 5 funds are buying while 8 are selling, with 3 holding steady. But one name on the buy side towers above everything else — and it's making one of the most concentrated bets in recent 13F history.
Quick Answer
Across the funds we read directly from SEC filings, the largest Zoom position in the Q2 2026 13Fs (period ending 30 June 2026) is Renaissance Technologies at $205M (2,380,704 shares). Measured against the size of each filer's book rather than in dollars, the most concentrated holder is Renaissance Technologies, where Zoom is 0.3% of everything they report. Every figure here is aggregated by CUSIP from the filer's own information table with put/call rows excluded — a 13F lists options beside shares, and adding them together is what produces the inflated stakes quoted elsewhere. Filings lag roughly 45 days: this is positioning as of 30 June 2026, not today, and not investment advice.
Zoom Institutional Snapshot
| Metric | Value |
|---|---|
| Funds Buying | 5 |
| Funds Selling | 8 |
| Funds Holding | 3 |
| Active Funds Tracked | 16 |
A 5-to-8 buy-sell ratio leans bearish on the surface. But the dollar-weighted picture tells a completely different story, dominated by one extraordinary position that dwarfs all selling activity combined.
Who holds Zoom, and how much it matters to them
Read from each filer's Q2 2026 information table (period ending 30 June 2026).
| Fund | Position | Shares | Share of the fund's 13F book |
|---|---|---|---|
| Renaissance Technologies | $205M | 2,380,704 | 0.3% of $72.62B |
| Citadel Advisors | $57M | 657,209 | 0.0% of $171.84B |
| Millennium Management | $24M | 273,645 | 0.0% of $142.92B |
The last column is the one worth reading. A multi-strategy fund reporting a $100B+ book can hold a large dollar amount of Zoom that means almost nothing to it, while a concentrated fund holding less in dollars may have several percent of its entire book in the name. Rankings by dollar value hide exactly that difference.

Comparing each filer's Q1 2026 table with its Q2 2026 one, by share count — the change is what shows conviction, not the size of the position.
| Fund | Q1 2026 shares | Q2 2026 shares | Change |
|---|---|---|---|
| Citadel Advisors | 4,230,754 | 657,209 | -84% |
| Millennium Management | 652,654 | 273,645 | -58% |
| Renaissance Technologies | 2,458,804 | 2,380,704 | -3% |
A fund absent from this table reported no Zoom position in either quarter.
What This Means for Individual Investors
Zoom in 2026 is a tale of two timelines — near-term momentum versus long-term transformation:
Bull case: Appaloosa's $1B position is the single strongest bullish signal in our entire coverage universe. Zoom generates massive free cash flow ($1.5B+), has a fortress balance sheet with $7B+ in cash, is aggressively deploying AI across its product suite, and trades at a fraction of its pandemic-era valuation. If the AI Companion features drive enterprise upselling and the contact center business scales, Zoom could rerate dramatically. Tepper is betting this happens.
Bear case: Revenue growth has structurally slowed from pandemic peaks. Microsoft Teams remains the dominant enterprise competitor, Google Meet is free, and Zoom's TAM expansion into contact center and email is unproven at scale. The quant funds selling suggest the near-term price action may remain challenging, and technical momentum favors the downside.
The bottom line: The 5-to-8 buy-sell ratio is bearish, but the dollar-weighted picture is overwhelmingly bullish thanks to Appaloosa's enormous conviction. This is a stock where you're essentially choosing sides: Do you trust David Tepper's contrarian instinct and long time horizon, or the quant funds' systematic near-term signals? History suggests that when Tepper makes bets this large, he's usually right — but the timing can take quarters to play out.

FAQ
Which hedge fund holds the largest Zoom position in 2026?
Index managers such as Vanguard, BlackRock and State Street hold the largest raw positions in almost every large-cap name, because they track the index rather than pick the stock. Among the active filers we read directly from EDGAR, the largest position in the Q2 2026 filings is Renaissance Technologies at $205M (2,380,704 shares).
Why is the Zoom buy-sell ratio bearish while the dollar-weighted picture looks bullish?
The 13F filings show 5 funds buying versus 8 selling, which leans bearish on a headcount basis. However, the single $1B Appaloosa increase plus accumulation from Vanguard, Fidelity, and State Street creates a dollar-weighted picture skewed toward buying. Counting funds and counting dollars can tell opposite stories.
What does Zoom's transition from pandemic darling to AI-first platform mean for investors?
Zoom is investing heavily in Zoom AI Companion, contact center, and enterprise collaboration to expand beyond the legacy video meetings business. The article describes this as a multi-quarter transformation: the bull thesis assumes AI features drive enterprise upselling, while the bear case highlights structurally slower growth and intense competition from Microsoft Teams and Google Meet.
Why are quantitative hedge funds selling Zoom while fundamental funds are buying?
Renaissance Technologies, Two Sigma, D.E. Shaw, Millennium, and Citadel all reduced their Zoom positions, suggesting their systematic models flag deteriorating near-term momentum or unfavorable factor signals. Fundamental contrarian managers like Appaloosa instead focus on cash flow ($1.5B+ FCF), balance sheet strength, and a compressed valuation. The divergence reflects different time horizons more than disagreement on the company.
How should retail investors interpret 13F data on Zoom?
13F filings are reported with a delay and only show long equity positions, so they are an informational signal rather than a real-time trading guide. They are most useful for understanding which institutional investors have conviction in a name and how positioning is shifting across the cycle. Always combine 13F data with your own research on fundamentals, valuation, and risk tolerance.
