Expensive bets against CoreWeave are getting smashed as shares soar

CoreWeave is behaving like it’s a twice-levered version of a US retailer that sources from China and just got major tariff relief.

Shares of the recently IPO’d cloud computing company are going bananas today, up 15%, ahead of its inaugural earnings report as a publicly traded firm on Wednesday after the close.

Like SoundHound AI, this has the fingerprints of a short squeeze, with an extra dose of strong appetite for upside in the options market.

Exchange data shows 30% of CoreWeave’s float was sold short heading into the start of May, during which time it’s rallied more than 40%. The stock is also fairly expensive to borrow, with an annual rate of about 8.3%, per Interactive Brokers data. That’s the third-highest borrow rate among stocks with a market cap of at least $20 billion, per ChartExchange.

Momentum returns to optics stocks as the release valve for AI optimism

Potentially imminent end to the war? Buy optics stocks.

Maybe not? Buy optics stocks anyway.

Effectively all the juice left in the AI trade is coming from optics (and memory) stocks. And the latter group is taking a bit of a breather today while the former continues to surge.

Shares of Ciena Corp., Lumentum, and Coherent are building on recent big gains and among the biggest gainers in the S&P 500 near midday, while Applied Optoelectronics is also surging on Thursday.

These companies all provide solutions that help information move around in data centers, and thus are key beneficiaries of the aggressive capex plans of hyperscalers. Nvidia has invested $2 billion apiece in Coherent and Lumentum in deals that also include purchase commitments.

Space stocks rip during a topsy-turvy day for the equity market

Satellite-services-from-space stocks surged Thursday after reports that Amazon is in talks to buy Globalstar, which provides voice and connectivity services from its satellite network. It also can’t hurt that the general mood around space is ebullient, following the successful launch of Artemis II on Thursday.

Planet Labs and ViaSat also soared on the news.

The gains for EchoStar — seen as a backdoor play at pre-IPO SpaceX exposure — and Rocket Lab were more muted, perhaps because a deep-pocketed competitor like Jeff Bezos getting serious about space services could complicate the plans of the two largest commercial space launch companies.

Rocket Lab and SpaceX see launch services as key to their aspirations of being major providers of voice and data services from low-Earth orbit satellites.

Tesla CEO Elon Musk’s SpaceX is the dominant provider of such services, and the early rumors on the company’s planned IPO — expected to be the largest ever — suggest the market is very excited about the prospects for the industry.

Elsewhere in the space stock world, Intuitive Machines — a maker of space infrastructure that provides services to NASA for lunar missions — also rose.

Tesla delivered 358,023 vehicles in Q1, short of expectations

Ahead of its first-quarter earnings later this month, Tesla on Thursday announced that it delivered 358,023 vehicles in the quarter.

Analysts polled by FactSet had expected 380,500 vehicle deliveries in the first quarter this year, while Tesla last month released its own company-compiled Wall Street consensus estimate — something it began doing in the fourth quarter of 2025 — of 365,645 vehicles.

The Texas-based company produced some 408,000 vehicles, meaning that it made 50,400 more vehicles than it sold during the quarter. That’s the largest gap in Tesla’s history, surpassing the previous record set in Q1 2024.

Shares extended losses in premarket trading on Thursday, falling more than 4%.

The deliveries figure is still up from the same quarter last year, when Tesla delivered fewer than 337,000 vehicles amid intensifying competition in China and flailing public perception over CEO Elon Musk’s involvement with the Trump administration.

As of 3 p.m. ET on Wednesday, event contract odds held a slightly less optimistic view than the broader analyst community, but a sunnier view than the figure Tesla put forward. 52% of traders predicted Tesla’s Q1 deliveries would come in at more than 360,000, 40% thought the figure would be higher than 370,000, and 15% estimated it would be higher than 380,000.
