View all 684 holding institutions

Across its top 20 institutional holders, OKLO's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 9/100, avg. turnover score 48/100).

Notable Holders

OKLO ranks #802 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

OKLO is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.

OKLO is a top-conviction position for Portland Investment Counsel Inc. — at 8.6% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in OKLO belongs to Jane Street Group, LLC, but the position matters far more to Portland Investment Counsel Inc., who has 8.6% 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.

Van Eck Associates CORP has added to its OKLO position for two straight quarters, increasing it by $130.2M to reach $414.1M today.

BlackRock has trimmed its OKLO position for two straight quarters, cutting it by $680.9M while still holding $382.6M.

OKLO is up 1.1% today, and institutions have been net buyers of $770.1M this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Company Fundamentals

OKLO reported a net loss of $105.7M in its latest fiscal year.

  • Not yet profitable — net loss of $105.7M in the latest fiscal year
  • Net income declined year over year, from -$73.6M to -$105.7M
  • Operating cash flow was negative, using $82.2M in cash
  • Current ratio of 49.08x — enough short-term assets to cover short-term liabilities
  • Liabilities run 0.04x equity — within a conventional range

Smart Money Convergence

OKLO 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 2026-06-30 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.
