AI mania tanks CoreWeave’s Core Scientific acquisition — it buys Python notebook Marimo

Core Scientific shareholders on Thursday voted down an all-stock acquisition supply from companion and competitor CoreWeave that was valued at the time at $9 billion.  

They did so following a vote-no suggestion from their largest shareholder, Sina Toussi of Two Seas Capital, a agency that focuses on post-bankruptcy corporations. Core Scientific emerged from its chapter in January 2024.  

Core Scientific, which started as a crypto miner and still is one, shares that early historical past with AI data middle supplier CoreWeave, which also began as a miner.  

But CoreWeave, with investor and companion Nvidia, has now transitioned to serving AI workloads. From its IPO until now, its inventory has soared from a $14 billion market cap to $66 billion today (about $140 per share) as traders view it as a method to get in on the AI action. It has been spending those shares on acquisitions.  

CoreWeave had already signed a $10 billion, 12-year contract with Core Scientific to make use of its services for AI providers, even as it nailed down a deal announced in July to purchase the company outright. The supply was a premium to Core Scientific’s share worth at the time.

But investor Toussi thinks Core Scientific can flip into another CoreWeave by itself. “Since the transaction was announced in July, investment in AI infrastructure has accelerated, driving equity valuations of Core Scientific’s peers to ever-greater heights,” he wrote in his opposition letter. “Why would anyone vote for a transaction worth a mere $16.40 per share?” 

So traders turned down the deal and CoreWeave walked. Core Scientific’s inventory rose on the news, and the company is now buying and selling at a $6.6 billion market cap.

Investors turning down acquisition bids in pursuit of larger gives is another signal that we’re in — or not less than headed for — an AI bubble. 

Meanwhile, CoreWeave is still purchasing. On Thursday, it circled and acquired Marimo, an open source Jupyter Notebook competitor, for an undisclosed sum. PitchBook estimates Marimo has raised about $5 million.

Python notebooks are dev instruments that mix code, wealthy media, and explanatory textual content right into a single, shareable file. They’re often used for interactive data analysis in addition to AI app development, serving to CoreWeave as it makes an attempt to maneuver up the stack from internet hosting to AI app constructing.
