NEW YORK, July 26, 2026 — ARK Investment Management, the firm led by renowned investor Cathie Wood, has acquired 160,151 shares of Tesla Inc. (NASDAQ:TSLA) following the electric vehicle maker's disappointing second-quarter earnings report. The purchase, valued at approximately $50.1 million based on Friday's closing price of $313.03, signals a contrarian bet on margin recovery despite a sharp earnings miss.
Tesla's stock tumbled 14.5% on Thursday and slipped another 2.1% on Friday, culminating in a 17.8% weekly loss. The broader market also declined, with the Nasdaq falling 2.1% and the S&P 500 dropping 0.6% over the same period.
The earnings report revealed a stark contrast between delivery volume and profitability. Tesla delivered a record 480,126 vehicles in the quarter, generating revenue of $28.236 billion — 2.4% above the company-compiled consensus of $27.584 billion. However, operating income came in at just $398 million, a staggering 73.5% below the $1.503 billion analysts had expected. The implied operating margin of 1.4% was far short of the 5.4% consensus, highlighting significant margin compression.
Underlying unit economics deteriorated as the average revenue per vehicle fell to $42,730 from $45,345 in the prior period. Revenue from regulatory credits also plunged 67% to $146 million. These factors, combined with rising costs, contributed to the margin squeeze.
CEO Elon Musk characterized 2026 as "a massive capex year," with capital spending projected to exceed $25 billion, driven by investments in artificial intelligence and manufacturing. First-half capital expenditure more than doubled to $8.28 billion, while research spending surged 49% to $2.37 billion. Musk expressed confidence that these investments would deliver "incredible returns."
Investor concerns extend beyond near-term margins to the monetization of Tesla's autonomous driving technology. The company disclosed 2.5 million paid robotaxi miles, but only 380,000 of those miles were driven without a safety observer. By comparison, Alphabet Inc.'s (NASDAQ:GOOGL) Waymo has accumulated over 220 million miles of fully autonomous driving. Tesla reported approximately 1.5 million active Full Self-Driving subscriptions, up 56% year-over-year, which could provide a more immediate software revenue stream.
ARK's purchase underscores Wood's conviction in Tesla's long-term potential, even as the stock faces headwinds from declining prices, reduced credit revenue, and elevated expenses. Tesla remains the top holding in the ARK Innovation ETF (BATS:ARKK), accounting for 9.38% of the fund's assets as of Friday.
Looking ahead, investors will monitor analyst updates and additional ARK trading disclosures. The Federal Reserve's July 28-29 meeting also looms, with potential rate decisions likely to influence growth stocks. For Wood, the thesis now hinges on Tesla's ability to demonstrate operating income improvement through software revenue and disciplined cost management.
