CBRS
The AI trade needs a new mascot
Cerebras Systems is having one of those post-IPO glow-ups where the market can’t stop looking. Fresh off what’s being called the largest IPO of 2026, the AI chipmaker is now pulling in fresh money from Cathie Wood’s ARK Invest, which disclosed a June 1 buy of 62,669 shares worth about $14.85 million.
That’s not exactly pocket change, and it comes on top of other recent ARK purchases. In other words, the firm isn’t just window shopping — it’s building a position and making a point.
The ETF crowd showed up too
Then Tradr ETFs crashed the party with two new leveraged products tied to Cerebras:
- CBRX, a 2x long daily ETF for traders who think the stock keeps ripping
- CBRZ, a 2x short daily ETF for anyone who wants the opposite bet
Both charge a 1.49% expense ratio, which is the kind of fee you only accept when you’re chasing volatility like it’s the last Uber after midnight.
Why this matters for investors
This is bigger than one buy ticket. It’s a sign that Cerebras is becoming a live wire in the AI infrastructure trade — the kind of name ETF issuers, momentum traders, and growth investors all start orbiting at the same time.
ARK also reportedly bought about $63.35 million of Nvidia while trimming roughly $56.88 million of AMD, which is a nice reminder that the AI chip battlefield is basically a rotating game of musical chairs. But the headline here is Cerebras: a newly public pure-play AI hardware name now attracting both capital and derivatives-style products.
Big picture: when the market starts creating both a bull ETF and a bear ETF for the same stock, you know the volatility buffet is officially open.
