Ark Invest, the innovation-focused fund run by Cathie Wood, has bought 78,756 shares of Cerebras Systems, adding to its growing position in the AI chipmaker. The purchase, made on August 19, is part of a string of buys that started after Cerebras went public in May.
Market Context
Since its IPO, Cerebras has seen significant growth, with its shares closing at $311 on the first day of trading, a 68% increase from its IPO price of $185. The company's core technology, the Wafer Scale Engine, takes a different approach to chip design, using the entire silicon wafer as a single chip, resulting in a processor with more compute power for training large AI models.
Financial Performance
Cerebras reported Q2 core revenue of $209.9 million, a 103% year-over-year increase, and raised its full-year guidance. The company's revenue growth has been driven by its unique chip design, which has attracted the attention of innovation-focused investors like Wood.
Investment Strategy
Ark's purchase of Cerebras shares is part of its broader investment theme of AI infrastructure, as outlined in its Big Ideas 2026 report. The fund has been steadily building its position in Cerebras since its IPO, and the latest purchase suggests that Wood is comfortable buying into volatility rather than chasing momentum.
