The most insane trading day for Opendoor yet, charted

Opendoor traded more than Meta in furious, frenzied trading yesterday that echoed the peak GameStop era.

The explosion of retail enthusiasm over struggling online real estate company Opendoor Technologies is propelling trading activity in the stock into the stratosphere of the most valuable, well-known companies in the world — and in many cases, well past them.

It’s hard to contextualize just how insane it is that a company that, until very recently, was a penny stock with a market cap in the hundreds of millions is now trading more than tech giant Meta.

As you would expect, trading volumes tend to correlate strongly with the market value of a stock. There are outliers, of course — Palantir is one that continues to punch above its weight — but for the most part, there’s a clear correlation between market cap and volume traded. Even in the most liquid market in the world, US equities tend to take a little over 100 days of typical trading to turn over their entire market cap.

Put another way, the average stock in the S&P 500 Index traded 0.87% of its market cap yesterday, per FactSet data. On a relative basis, Domino’s Pizza, which reported decent earnings yesterday thanks its efforts in the world of stuffed crusts, was the most active in the S&P 500 — turning over just under 7% of its market cap in Monday’s session.

Opendoor Technologies was completely off the charts, trading 298% of its closing market cap (an important distinction because it, uh, varied a lot yesterday).

That’s not too far off how much GameStop traded at the peak of its January 2021 frenzy: 316% of its market value.

Retail darling Planet Labs soars on earnings pop for second straight quarter

Planet Labs, which operates a network of satellites that record data, images, and information about the Earth, surged more than 40% after reporting better-than-expected quarterly numbers before the open of trading Monday.

It was the second straight quarter when the money-losing company’s quarterly update generated a massive market reaction. The stock jumped nearly 50% after numbers came out in June.

The company, which went public via SPAC in 2021, raised its full-year revenue guidance and notched its second straight quarter of positive free cash flow. Analysts and investors watch free cash flow closely as it can signal when a company’s business is starting to become more durable.

While the company is small — roughly $2.5 billion in market cap — it has posted pretty serious gains, rising almost 300% the past 12 months. Planet Labs also appears to have a fairly large retail shareholder base.

Just 57% of its float is in the the hands of institutional investors, according to FactSet data. That’s roughly the same as other retail favorites such as Palantir, though Planet Labs is no where near as highly valued as the defense data and AI software company led by CEO Alex Karp.

OpenAI’s cash burn suggests selling Nvidia because of reported Broadcom chip orders may not make much sense

When Broadcom announced that it booked $10 billion in new orders from a customer reported to be OpenAI, shares of their major AI chip rivals tanked.

The judgement of the Invisible Hand was that this was nearly a zero-sum outcome: $130 billion of market cap erased from Nvidia and Advanced Micro Devices, and a $135 billion increase in Broadcom’s market value.

But looking at this from the perspective of near-term cash flows, the market’s view seems off.

The Information is reporting that OpenAI now expects to burn through $115 billion by the end of 2029 (or more than 11 seasons’ worth of NFL broadcasting rights).

Let’s zoom in on this tidbit from The Information:

But the biggest change emerging from OpenAI’s latest projections was to its cash flows. The company projected it will burn more than $8 billion this year, or roughly $1.5 billion higher than its prior projection from earlier this year. Cash burn will more than double to more than $17 billion next year—$10 billion higher than what the company earlier projected

That $10 billion fits all too neatly with the $10 billion in orders from a major new customer that Broadcom CEO Hock Tan pointed to in the chip designer’s earnings call.

(Cheers to @lokoyacap for flagging this on X)

Assuming the reporting around OpenAI and Broadcom is accurate, these orders for ASICs don’t look to be displacing what the ChatGPT creator was going to spend on Nvidia’s GPUs, but are just in addition to it! The money’s not coming out of Jensen Huang’s pockets, it’s coming out of OpenAI’s coffers. Their spending budget is just getting bigger.

Perhaps if you squint, there’s a world in which OpenAI may prefer to have an additional $10 billion in Nvidia GPUs rather than ASICs, and I am still of the belief that hyperscalers diversifying their chip sources due to constrained top-end supplies isn’t a good sign for the company selling the most in-demand product.

But it’s quite intriguing, and says something about the depth of the pockets that fuel the AI boom, that OpenAI’s reported new relationship with Broadcom has seemingly no direct negative financial impact on Nvidia in the near term.

Broadcom’s post-earnings romp continues on heavy volumes

As Broadcom enjoys a rush of new orders from a major new customer (reported to be OpenAI), it’s also reveling in a flood of traffic into the stock.

Volumes are running at 2.5 times their daily average through 1:20 p.m. ET as traders continue to bid up shares in response to the brighter outlook for 2026 revenues, which sent the stock up 9.4% on Friday.

The chip designer is basking in a flood of price target hikes from Wall Street, with Bank of America, JPMorgan, Argus Research, Citigroup, Bernstein, Deutsche Bank, Morgan Stanley, Barclays, Piper Sandler, Rosenblatt Securities, Wells Fargo, and Susquehanna upping their view on how high shares can go since the company reported earnings last week.

Separately, Taiwanese industry outlet DigiTimes is reporting that orders from several other leading tech companies for custom-made Broadcom chips (or ASICs) are “already in the pipeline.” This report has not been corroborated by our own or any other publication’s reporting to date.

SpaceX spectrum deal sends would-be rivals lower

Shares of struggling satellite services company EchoStar soared Monday, after the company — which had recently tottered close to bankruptcy — announced the sale of some of its wireless spectrum licenses to Tesla CEO Elon Musk’s SpaceX for $17 million.

The sale provides a competitive advantage to Musk’s growing Starlink satellite services business, as the licenses it is acquiring from Echostar allows Starlink to operate ground based broadband and cellphone services, the Wall Street Journal reported.

Entities that stood to be hurt by the emergence of a Musk-led SpaceX Starlink service got hit hard on the news. AST SpaceMobile, which has plans to offer a similar satellite-to-consumer cellular service, tumbled.

So did wireless tower providers like Crown Castle and American Tower. Low cost cellular service provider T-Mobile, which had a deal with SpaceX, also slumped, as Luke noted earlier, along with other large wireless telecommunication services providers.

The wireless telecommunications industry grouping within the S&P 500 was down more than 2.5% shortly after noon, making it the worst performing industry within the S&P 500 on Monday.
