Cerebras delivers monster IPO pop as traders clamor for fresh AI investment opportunities

The biggest IPO of the year so far is a prelude to the AI deluge.

This looks like one helluva IPO pop:

Cerebras Systems increased the expected price (and size) of its long-awaited initial public offering from a range of $115 to $125 at the start of the week all the way to $185, raising $5.5 billion.

But it opened at a whopping $350 in its Nasdaq debut, giving the company a market cap of at least $75 billion — and more than that on a fully diluted basis.

“Pretty good day, huh?” CEO Andrew Feldman said in an interview on Bloomberg TV, after being told the stock was indicated to open at $350.

The IPO was more than 25x oversubscribed, per Feldman. With investor appetite like this, it’s little wonder that SpaceX, OpenAI, and Anthropic are champing at the bit to join Cerebras in making this leap.

Cerebras, an AI chip designer, counts OpenAI and Amazon among its customers. Its offerings aim to provide more of a one-stop shop for AI compute rather than a highly specialized key ingredient in the data center stew. That is, its wafers are physically much larger than GPUs, which can unlock more efficiencies in moving around information.

“There’s just an extraordinary demand right now for fast inference,” added Feldman. “We’re the fastest, not by a little big, but by more than an order of magnitude — we’re 15x faster than the next nearest competitor.”

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.
