View all 862 holding institutions

Across its top 20 institutional holders, RIVN's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 16/100, avg. turnover score 48/100).

Notable Holders

RIVN ranks #598 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

RIVN is a disclosed holding of Baillie Gifford (Baillie Gifford & Co.), one of the tracked superinvestors on AlphaSMO — it makes up 0.7% of that fund's own 13F portfolio.

RIVN is a top-conviction position for Amazon Com Inc — at 62.1% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

StoryOne LLC has added to its RIVN position for two straight quarters, increasing it by $1.2M to reach $2.0M today.

Mn Services Vermogensbeheer B.V. has trimmed its RIVN position for two straight quarters, cutting it by $1.1M while still holding $3.4M.

RIVN is down 3.1% today, but institutions show net buying of $1.8B this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

RIVN reported a net loss of $3.2B over the trailing twelve months.

  • Not yet profitable — net loss of $3.2B over the trailing twelve months
  • Revenue grew 14.2% year over year
  • Net income improved year over year, from -$3.5B to -$3.2B
  • Operating cash flow was negative, using $779.0M in cash
  • Current ratio of 2.33x — enough short-term assets to cover short-term liabilities
  • Liabilities run 2.24x equity — a highly leveraged balance sheet worth noting

Smart Money Convergence

RIVN does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-09-30 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.
