ARK Resumes Buying Robinhood as Event Contract Volumes Surge to 4.7 Billion in August

What happened

Cathie Wood's ARK fund bought Robinhood shares twice in early September, reversing a summer of selling, according to The Motley Fool. The article highlights that customers traded 4.7 billion event contracts in August, a 15-fold increase year-over-year and above the 3.9 billion traded in May 2026 noted in the master report. This surge bolsters the revenue diversification story that already saw event contracts generate $156 million in Q2 2026, surpassing crypto revenue of $100 million. However, the master report maintains a WAIT rating due to unresolved legal risks around event contracts and a rich valuation at roughly $90 per share, with P/E near 39 and EV/EBITDA near 35. The new volume data and ARK's buying are encouraging but do not yet resolve the core uncertainties around regulatory continuity and whether elevated trading intensity can be sustained without faster customer and deposit growth.

Implication

August event contract volume of 4.7 billion contracts indicates durable demand and likely supports Q3 revenue above Q2's $156 million, strengthening the non-crypto revenue thesis. Yet legal challenges could still restrict event contracts in key states, and no court or regulatory resolution has emerged to de-risk that revenue stream. ARK's purchases may reflect short-term trading strategy or portfolio adjustments rather than a fundamental endorsement, so they should not outweigh the filing-level risks. At current prices, the stock offers little margin of safety given its high earnings multiples and dependence on sustained high-frequency activity. Investors should watch upcoming monthly metrics and legal developments; a decline toward $78 would present a more attractive entry, while a sustained break above $108 would require proof that event contracts are legally secure and volumes are sticky.

Thesis delta

The master thesis held a WAIT rating based on high valuation and legal uncertainty around event contracts. New data shows event contract volumes accelerated to 4.7 billion in August, up from 3.9 billion in May, and ARK Invest resumed buying, indicating stronger adoption than previously modeled. This modestly increases the probability of the bull scenario but does not eliminate the bear risk from legal challenges, so the rating remains WAIT with our conviction slightly improved and focus on Q3 disclosures.
