View all 1083 holding institutions

Across its top 20 institutional holders, NBIS's holder base skews toward low-concentration, high-turnover investors on average (avg. concentration score 18/100, avg. turnover score 52/100).

Notable Holders

NBIS ranks #419 out of 37503 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

NBIS is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 0.3% of that fund's own 13F portfolio.

NBIS is a top-conviction position for Accel Leaders 4 Associates L.P. — at 100.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in NBIS belongs to Goldman Sachs Group Inc, but the position matters far more to Accel Leaders 4 Associates L.P., who has 100.0% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Goldman Sachs Group Inc has added to its NBIS position for two straight quarters, increasing it by $8.8B to reach $9.1B today.

Man Group plc has trimmed its NBIS position for two straight quarters, cutting it by $14.0M while still holding $2.3M.

NBIS is down 4.3% today, but institutions show net buying of $30.8B this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

NBIS closed its latest fiscal year with net income of $82.5M, and currently trades at a P/E of 628.0.

  • Profitable — net income of $82.5M in the latest fiscal year
  • Revenue grew 479.0% year over year
  • Net income improved year over year, from -$641.4M to $82.5M
  • Generated $384.8M in positive operating cash flow
  • Current ratio of 3.08x — enough short-term assets to cover short-term liabilities
  • Liabilities run 1.71x equity — within a conventional range

Game Theory Scenarios

Neutral— Wait & Watch

Institutions aggressively accumulating; insiders exclusively selling

Signal Basis

13F data shows institutions net-bought approximately $30.8 billion with 720 net buyers versus 344 net sellers and 404 new positions against only 61 exits; conversely, insiders recorded zero purchases over both the 30-day and 90-day windows, with 43 sell transactions totaling roughly $40.6 million in the trailing 90 days, confidence_score at 0 — a clear directional divergence between the two signals.

Confirmation

A subsequent 13F quarter showing continued institutional accumulation alongside any insider buy transactions would shift the bias toward bullish.

Invalidation Risk

Sustained or accelerating insider selling combined with a deceleration in institutional net buying would tilt the analysis bearish.

Compiled by AI directly from institutional holders' regulatory filings on SEC EDGAR; describes past institutional behavior only. Not a substitute for independent investment research.

Smart Money Convergence

NBIS does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
