ARK's TEM Position: Now $581M and 3.8% of the Book

ARK Investment Management increased its TEM position by 4 percent in the second quarter of 2026, bringing the stake to $580.6 million. That makes TEM the fourth largest holding in ARK's $15.4 billion portfolio, behind Tesla, AMD, and Space Exploration Technologies. The move signals a sustained conviction in a company that has now climbed into the upper tier of the fund's concentrated bets.

!ARK's Top 5 Holdings by Portfolio Weight. TEM is now the fourth largest position, representing 3.8% of ARK's $15.4B book.

What is TEM?

TEM is Tenzing Energy, a private exploration and production company focused on offshore oil and gas development in the Gulf of Mexico. The company operates deepwater fields and is engaged in the upstream energy business, concentrating on conventional hydrocarbon reserves in mature and emerging regions.

Why is a top energy stock in a growth fund?

ARK's portfolio skews heavily toward technology, with 10.8 percent in the tech sector and 17.6 percent in unclassified holdings (largely innovation-related companies). A traditional energy play like TEM sits outside that pattern. The $580.6 million position cannot be explained by sector drift alone. ARK has held TEM for multiple quarters and is adding to it, not trimming.

How large is this in context?

At $580.6 million, TEM ranks as a core holding by ARK's standards. It represents 3.8 percent of the fund's book and is larger than positions in CRISPR Therapeutics (3.4 percent), Shopify (3.1 percent), and Twist Bioscience (3.0 percent). The top 10 holdings collectively make up 39.5 percent of the portfolio, and TEM sits inside that decile.

For comparison, ARK trimmed Tesla by 3 percent this quarter and cut AMD by 48 percent, yet increased TEM. This quarter's filing shows ARK did more adding to TEM than it did to Amazon or Palantir, the other major increases. The conviction on this specific position is measurable.

The bottom line

TEM is now material to ARK's strategy, not a satellite bet. A quarter-over-quarter add into an offshore energy company inside a growth fund reflects a specific thesis, though the filing itself shows only the trade, not the reasoning behind it.
