Will SoftBank Regret Selling Off Nvidia Again?

Plus: Sora's unsustainable economics.

Forbes

Presented by

Welcome back to The Prompt, 

Softbank has sold its entire stake in Nvidia—worth some $5.8 billion—to support its $30 billion investment in OpenAI, the Japanese tech conglomerate disclosed in its earnings report today. The news,  which caused the chipmaker's stock to dip 2%, highlights just how deeply tech companies' fortunes are woven together. (Though Nvidia wasn't its only sell-off to fund its OpenAI investment: Softbank also dumped 40 million T-Mobile shares, worth $9.17 billion.) 

Surprisingly, this isn't the first time Softbank has cashed out of the chipmaker. The company had accumulated a $4 billion stake in Nvidia before deciding to sell it in 2019. SoftBank founder and CEO Masayoshi Son said last year he regretted exiting that investment, which would have earned SoftBank more than $150 billion, noting, "The fish that got away was big." Time will tell if this second big sale will pay off. 

Now let's get into the headlines.

HUMANS OF AI
AI has spilled into virtually every type of business. But one of the most obvious (and competitive) categories is customer service. Sierra, valued at $10 billion, builds AI agents for customer service tasks like canceling subscriptions and issuing returns, and is growing fast: the company told Forbes it expects annualized revenue to cross $100 million by January 2026. Founders Bret Taylor and Clay Bavor, are newly minted billionaires per Forbes estimates, with each owning a roughly one-quarter stake in the company.  In a sea of young founders, the two 40-something-year-old entrepreneurs stand out. Taylor is among the most celebrated executives in Silicon Valley with notable stints at Google (co-creator of Google Maps), Facebook (CTO who helped create the famous "Like" button), Twitter (board chairman who clashed with Elon Musk during his Twitter takeover), Salesforce (co-CEO) and now OpenAI (board chairman), making him the "the Forrest Gump of the tech world," my colleague Richard Nieva writes.

SHOW ME THE MONEY
Millions of people have made silly AI videos with OpenAI's TikTok-style app Sora. Its feed now includes a jumble of copyright-infringing characters, Ring security videos, farting celebrities (deceased only), and some truly disturbing home shopping network ads. But the AI giant is spending some $15 million per day to create those AI-generated videos, per Forbes' estimates. That's money it can't afford to burn, with mounting losses (up to $12 billion last quarter) and steadily increasing compute costs. Bill Peebles' OpenAI's head of Sora, recently admitted, "The economics are currently completely unsustainable."

TALENT RESHUFFLE
Meta's Chief AI Scientist Yann LeCun is planning to leave the social media giant to start his own venture, The Financial Times reported. LeCun, a French American computer scientist and a pioneer in the fields of machine learning and artificial intelligence, reportedly plans to work on so-called world models that learn from visual data. The departure comes after CEO Mark Zuckerberg doled out $100 million pay packages to poach top tier AI researchers from companies like OpenAI and Google DeepMind and hired Scale CEO Alex Wang to lead its AI efforts. That meant LeCun was reporting to Wang, FT reported — perhaps a less desirable position for one of the AI world's preeminent researchers. 
Over the last few months, OpenAI CEO Sam Altman has been on a tear of dealmaking, announcing multibillion dollar agreements with the biggest tech companies in the world. He's committed to spending a grand sum total of $1.4 trillion on datacenters in the coming years — an eyebrow-raising figure for a company which claims its annual revenue is projected to reach $20 billion this year, begging an all-important question: What happens if he can't pay?

At an event this week, OpenAI CFO Sarah Friar seemed to suggest that the government could act as a "backstop" for the company's commitments — comments she later walked back. And in a long-winded post on X, Altman addressed the question of what happens to OpenAI if its web of deals falls apart:

"If we screw up and can't fix it, we should fail, and other companies will continue on doing good work and servicing customers," Altman said. "...We of course could be wrong, and the market—not the government—will deal with it if we are."

The odds don't look great right now. In order to come through on its compute commitments, OpenAI's revenue would have to grow to an estimated $577 billion by 2029, roughly the size of Google's revenue that same year, Tomasz Tunguz, a general partner at Theory Ventures, wrote in a recent blog post. 

But OpenAI has options. One likely scenario is that the AI company pays for and utilizes only a portion of the compute it has booked, said D.A. Davidson analyst Gil Luria. In that case, companies like Oracle, Amazon, Microsoft, CoreWeave and others will most likely renegotiate the contracts and ensure they get at least some amount of business from OpenAI, especially if the alternative is getting none at all. "They don't want OpenAI to go bankrupt, so their incentive is to renegotiate," he told Forbes.

Experts note chief dealmaker Altman doesn't have anything to lose. He has repeatedly claimed he does not have a stake in the company, and won't have a stake even after OpenAI has restructured to become a public benefit corporation. "He has the upside, in a sense, in terms of influence, if it all succeeds," said Ofer Eldar, a corporate governance professor at the UC Berkeley School of Law. "He's taking all this commitment knowing that he's not going to actually face any consequences because he doesn't have a financial stake."

As OpenAI has grown in prominence, tech giants have clamored to strike deals with the AI behemoth. "More of the world wants to work with us, so deals are quicker to negotiate," Altman said recently. And they've reaped the upsides: Oracle, Nvidia, AMD and Broadcom gained a collective $636 billion in market cap on the days their deals were announced "The math that Mr. Altman is doing in his head is 'they need me more than I need them,'" Luria said.

"If you owe the bank a hundred thousand dollars, the bank owns you. If you owe the bank a hundred million dollars, you own the bank," said Lloyd Walmsley, a Mizuho analyst who covers Meta, Google and Amazon.

MODEL BEHAVIOR
Always check what's under the hood. Sometimes it could be humans disguised as AI. Sam Udotong, CTO and cofounder of AI notetaker Fireflies AI, shared on LinkedIn that early versions of the tool didn't involve AI at all. Rather the founders would dial into calls as "Fred from Fireflies" and manually take detailed notes, sending them to the customer 10 minutes later. They did this for more than 100 meetings before deciding to automate the tedious process. That sounds a lot like fraud.
