Can CoreWeave Turn Weights & Biases Into a Competitive Advantage?
CoreWeave, Inc. CRWV has announced the acquisition of Weights & Biases, a leading AI developer platform, as part of its strategy to strengthen its leadership in high-performance AI cloud infrastructure. First announced in March 2025, the acquisition combines CoreWeave's powerful compute capabilities with Weights & Biases' suite of tools for model training, evaluation and monitoring—creating a unified, end-to-end platform for AI development. This integration is designed to accelerate AI innovation and enhance user productivity, while continuing to support flexible deployment across any infrastructure.
The acquisition of Weights & Biases added a customer base of more than 1,400 organizations. Management believes this combination will unlock greater value for the shared customers. At the same time, it continued to raise the bar on performance, becoming the first to deploy GB200 Grace Blackwell systems at scale on an AI cloud platform, powering top AI innovators like Mistral, IBM and Cohere.
Earlier this month, CoreWeave and Weights & Biases made their first joint product launch, showcasing the rapid integration and execution. Three major offerings were introduced, which aim to help AI teams develop, deploy and iterate faster by combining CoreWeave's cloud infrastructure with Weights & Biases' developer platform.
The launch comprises Mission Control Integration, which helps AI engineers quickly diagnose and resolve training issues by linking infrastructure events to training runs; Weights & Biases Inference, enabling access to top open-source models through a single interface; and Weave Online Evaluations, which monitors production AI agent performance in real-time across any cloud. Together, these products create a seamless platform to accelerate innovation, improve efficiency and empower developers to scale cutting-edge AI solutions with confidence.
For 2025, CoreWeave has guided revenues to be in the range of $4.9-$5.1 billion, fueled by surging AI-infrastructure demand.
However, the company faces intense competition in the AI cloud space with Nebius Group N.V. NBIS and Microsoft Corporation MSFT.
NBIS & MSFT's Recent Acquisitions in the AI Space
CoreWeave's closest emerging competitor, Nebius, based in Amsterdam, is focusing on becoming a specialized AI infrastructure company. Unlike CoreWeave, Nebius has not pursued major acquisitions, but it has incubated a range of AI businesses. Its portfolio includes Toloka for data labeling and evaluation, TripleTen for tech education and Avride for autonomous driving technologies. In May 2025, Toloka secured $72 million in strategic funding led by Jeff Bezos's venture fund, underscoring the strength and potential of Nebius' in-house ventures. Nebius is betting on organic growth and vertical integration to build its position in the AI space.
Microsoft continues to expand its AI infrastructure through partnerships and investments. In collaboration with the Wisconsin Economic Development Corporation, the University of Wisconsin-Milwaukee and TitletownTech, Microsoft launched an AI Co-Innovation Lab on the UWM campus. The company is also integrating cutting-edge open-source models like DeepSeek into Azure and GitHub. With its extended partnership with OpenAI and the growing adoption of Azure OpenAI and Microsoft Copilots across its enterprise suite, Microsoft is positioning Azure AI as the core platform for the AI era. The company has more than 60,000 Azure AI customers, up nearly 60% year over year.

Warren Buffett announces US$6 billion in donations to five foundations
Warren Buffett, chairman and CEO of Berkshire Hathaway, smiles as he plays bridge following the annual Berkshire Hathaway shareholders meeting in Omaha, Neb., May 5, 2019. (AP Photo/Nati Harnik, File) NEW YORK — Famed investor Warren Buffett is donating $6 billion worth of his company's stock to five foundations, bringing the total he has given to them since 2006 to roughly $60 billion, based on their value when received. Buffett said late Friday that the shares of Berkshire Hathaway will be delivered on Monday. Berkshire Hathaway owns Geico, Dairy Queen and a range of other businesses, and Buffett is donating nearly 12.4 million of the Class B shares of its stock. Those shares have a lower and easier-to-digest price tag than the company's original Class A shares, and each of the B shares was worth $485.68 at their most recent close on Friday. The largest tranche is going to the Bill & Melinda Gates Foundation Trust, which will receive 9.4 million shares. The Susan Thompson Buffett Foundation will receive 943,384 shares, and the Sherwood Foundation, Howard G. Buffett Foundation and NoVo Foundation will each receive 660,366 shares. Buffett made waves a year ago when he said he plans to cut off donations to the Bill & Melinda Gates Foundation after his death and let his three children decide how to distribute the rest of his fortune. Berkshire Hathaway's Class B stock has climbed 19.1% over the last 12 months, topping the broad U.S. stock market's return of 14.1%, including dividends. Buffett is famous on Wall Street for buying companies at good prices and being more conservative when prices look too high. The bargain-hunting approach has helped him amass a fortune worth about $145 billion, with basically all of it in Berkshire Hathaway's stock. 'Nothing extraordinary has occurred at Berkshire; a very long runway, simple and generally sound decisions, the American tailwind and compounding effects produced my current wealth,' Buffett said in a statement. 'My will provides that about 99 1/2% of my estate is destined for philanthropic usage.'

Hudson's Bay landlords don't want Ruby Liu to move in, but retailer still has a shot
Social Sharing A group of Hudson's Bay's landlords don't want to transfer more than two dozen leases to B.C. billionaire Weihong (Ruby) Liu, but the department store still has a chance to get its way. The Bay, which filed for creditor protection in March, ran a process over the last several months to find buyers for leases belonging to it and Saks Canada. It agreed to sell up to 28 spaces to Liu. Three leases were transferred to her without any hiccups because they're in B.C. malls she owns, but another 25 are at properties held by a who's who of Canadian commercial real estate firms. Landlords for 23 of those sites oppose the transfer. Several have said in court they've been "very troubled" with their interactions with Liu and have had "no productive discussions, no meaningful disclosure." Liu insists if the court hands her the leases, landlords will warm to her and her plan to open a new department store in their properties. While the disagreement could serve as a roadblock to the Bay closing on its agreement with Liu, lawyers not involved in the case say the retailer has another route it can take to get a deal done. That route lies in changes to the Companies' Creditors Arrangement Act (CCAA) — Canada's main insolvency law — made in 2009, said Jeff Lee, a Saskatoon-based partner at MLT Aikins LLP. The changes laid out three criteria courts must consider when asked to assign leases to a new tenant. WATCH | Who is Ruby Liu? Who is Hudson's Bay benefactor and billionaire Ruby Liu? 3 days ago Duration 6:16 Ruby Liu, a billionaire with a big vision, now has legal permission to take over the leases of three former Hudson's Bay department stores located at three malls already under her ownership. For more on the new Bay benefactor, we're joined by retail analyst Carl Boutet. The first is whether or not the sale has the support of the monitor, a court-appointed, independent third party which helps guide businesses through creditor protection. In the Bay's case, the monitor is Alvarez & Marsal. It has yet to reveal whether it supports the Liu deal and did not respond to requests for comment. "Before any court application is brought forward, typically the company will test that out with them," Lee said. "They're not going to just sort of fly in blind and hope for the best." The second aspect for the court to mull is whether the proposed new tenant is suitable. Lee said that's determined by looking at whether they can perform the duties of the tenant and pay rent. Liu, who made her money in Chinese real estate, appears to have deep pockets but her experience comes from being a landlord rather than a tenant. The final aspect the court will consider is whether a transfer of a lease to Liu is "appropriate." Lee said people should think of it as asking this question: "Is what's proposed for this post-assignment lease relationship what people signed up for, or are they seeking to rewrite the lease or change the playing field so radically that it's not appropriate?" WATCH | What went wrong for Hudson's Bay: What went wrong with Hudson's Bay? 3 months ago Duration 5:49 That's where much of the tension could lie in the Bay case. "You can't go into CCAA as a tenant and then force your landlords to renegotiate their leases as a result," said Peter Tolensky, a Vancouver-based partner at Lawson Lundell LLP. The Canadian Press obtained a document last week that Liu's lawyer sent landlords outlining her plans. It says she will take on the leases on an "as is, where is" basis but doesn't mention the dining, entertainment, children's and fitness experiences she's told media she'd like to include in her department stores. It's unclear whether the leases allow for uses other than a Bay-like department store. Some lenders owed more than $100M A court faced with a request to reassign leases will weigh this context and think about whether "the landlord's world is being turned upside down by having this new tenant," said Geoffrey Dabbs, a B.C.-based founding partner at Gehlen Dabbs Cash. "The more it's a minor inconvenience for the landlord, the more likely the judge will order it," he said. While the Bay hasn't said whether it will seek an assignment, it's likely because any company in creditor protection has a duty to show the court it's doing its best to pay back companies and people it owes money to, Dabbs said. The Bay has a 26-page list of creditors, with some lenders owed more than $100 million each. Liquidation sales and a deal to sell the Bay trademarks to Canadian Tire for $30 million have put a dent in what's owed but selling leases to Liu would also help. Anyone who made an offer for leases had to make a deposit of 10 per cent of their estimated purchase price. Court documents show Liu made a deposit of $9.4 million, in addition to $6 million for the three approved leases, which would equate to a purchase price of $100 million for 28 leases. When a deal like this is reached, Dabbs said a company typically seeks landlord consent because commercial leases tend to have provisions stopping anyone from transferring a lease without a property owner agreeing. It's not uncommon for landlords to object because any leases that can't be sold and aren't assigned get turned back over to property owners who can choose how to fill them and under what terms. These are anchor leases, Tolensky noted. "So they're probably very favourable to the Bay or to the tenant in a lot of respects," Tolensky said, alluding to the fact that anchor tenants are often given attractive rents or terms. Thus, it's more advantageous for landlords to get their properties back, said Monica Beffa, founder of an Oakville, Ont., law firm. If they do, they can then charge higher rents, develop them for entirely new uses such as residential units or break them up into smaller parcels that can be rented by a wide array of tenants. If they don't and a court assigns the leases to Liu, landlords will likely be watching her closely to ensure she doesn't violate any terms of the agreement. Dabbs said: "The landlord may be cranky, if the tenant breaches, but put it this way, they don't want to rely on that.
