Notable Holders

ACHR ranks #1099 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

ACHR is a disclosed holding of Cathie Wood (ARK Investment Management), one of the tracked superinvestors on AlphaSMO — it makes up 1.0% of that fund's own 13F portfolio.

ACHR is a top-conviction position for Vestor Capital, LLC — at 6.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in ACHR belongs to California State Teachers Retirement System, but the position matters far more to Vestor Capital, LLC, who has 6.0% 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.

Jim Simons has added to its ACHR position for two straight quarters, increasing it by $17.3M to reach $19.7M today.

BlackRock has trimmed its ACHR position for two straight quarters, cutting it by $146.4M while still holding $285.0M.

ACHR is up 1.6% today, and institutions have been net buyers of $255.9M this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

ACHR 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.

Archer Aviation (ACHR) announced on August 9 that it signed a definitive agreement with Boeing to acquire all equity interests in Wisk Aero, SkyGrid, and Insitu, along with related entities — bringing Boeing's autonomous aviation, drone manufacturing, and airspace management businesses under one roof. Instead of cash, Archer will pay Boeing with newly issued Class A shares equal to 19.75% of its outstanding shares at closing, plus two warrants: one to buy $100 million worth of shares at $13.00, and another for $100 million at $17.88. Boeing is also locked up from selling the shares for 12 months after closing, and the deal still needs regulatory approvals before it can close.
