Four tiny stocks all traded more than Disney... and 476 other members of the S&P 500 yesterday

Quantum Computing, Rigetti Computing, Nukkleus Inc., and SoundHound AI traded nearly $10 billion collectively yesterday.

These days, you have to go well outside the S&P 500, which holds the largest American public companies, to find the stocks worth talking about. An emergent market theme is the spike in appetite for more speculative, volatile companies — ones with massive upside potential tied to buzzword-heavy business lines, but also little in the way of current revenues or profits.

This handful of relatively tiny companies are stealing the spotlight, with their trading volumes going absolutely nuts.

That amount of money trading in stocks that few people have heard of is unusual, but when you account for the size of these companies, the comparisons get even more staggering. Before we get into the details, some quick context. The average S&P 500 Index stock traded $818 million yesterday, per data from FactSet, or about 0.89% of its market cap — again, on average. Tesla, the most active stock overall, actually traded about 4% of its market cap.

Quantum Computing only has a market capitalization of about $2 billion. Yesterday, more than $3.3 billion changed hands in the company’s stock — meaning that it traded ~164% of its market cap in one session. Rigetti Computing turned over about ~94% of its market value, and the value traded in SoundHound AI was about 26% of its market cap.

But nothing compares to Nukkleus Inc. After announcing a strategic acquisition that pivots the company into the defense sector, the tiny company’s stock soared, gaining more than 700% in just one day. Per FactSet, more than $2 billion changed hands in the company’s shares yesterday. (Bloomberg estimates a lower amount, closer to $1.4 billion.) The company’s market cap is just $40 million, meaning that, on the FactSet numbers, traders bought and sold over 5,000% of its total market cap... in one day.

Why are these stocks soaring?

Quantum computing has been the shiny new object for traders chasing new thematic investing ideas in the wake of Alphabet’s December 9 announcement of a problem-solving breakthrough. The search giant said that its quantum computer completed a series of calculations would have taken the world’s best supercomputers 10 septillion years to finish. Smaller pure-play companies in this line of business, which had already been up anywhere from 175% to 715% so far this year, have since extended their year-to-date gains. Notably, Rigetti Computing and Quantum Computing have each more than doubled in a little over a week.

Rigetti, in partnership with other firms including Nvidia, was able to successfully use AI to calibrate a quantum computer (that is, setting it up so that it works and does whatever it’s being asked to do properly). That’s a significant potential time-saver that could aid the proliferation of this technology. Meanwhile, Quantum Computing secured a contract with NASA to process interferometric imaging data, which are images generated through the use of radar.

SoundHound AI, which sells voice-AI software, seems to have benefited from its legions of doubters amid an apparent short squeeze in the shares. Roughly one-quarter of its float is held by traders betting against the company — an increasingly painful position to have held.

iRobot files for Chapter 11 bankruptcy just 11 days after its record one-day gain

Last one to leave the Roomba, please turn off the lights.

iRobot, maker of robotic vacuums and other cleaning products, announced that it was filing for Chapter 11 bankruptcy on Sunday as part of a restructuring agreement that would see 100% of the company’s equity interests be acquired by its secured lender and its primary contract manufacturer, Shenzhen PICEA Robotics Co., Ltd. and Santrum Hong Kong Co., Limited.

In a press release, the company said that this move “will delever the Company's balance sheet and enable iRobot to continue operating in the ordinary course, pursue its product development roadmap, and maintain its global footprint.”

Shares of iRobot recently booked their biggest one-day gain on record, rising 74% on December 3 on the heels of a Politico report that the Trump administration was planning on going “all in” to boost the robotics industry.

That report spurred a wave of buying from traders who were presumably looking to get exposure to the theme, enticed by the name of a company that has “robot” in it, and less than fully versed on its financial position. Back in March, management had warned investors that “there is substantial doubt about the Company's ability to continue as a going concern for a period of at least 12 months.”

Volumes exceeded 228 million on Dec 3, also far and away a daily record for the stock.

Data center trade deep in the red

The data center trade is seeing its steepest sell-off since the market rout that was ignited by President Donald Trump’s Rose Garden tariff announcement back in April.

Goldman Sachs’ themed basket of AI data center shares was down more than 6% at around 12 p.m. ET, putting it on track for its worst day since the tariff announcement.

Losses hammered seemingly every form of input needed for the sprawling concrete server warehouses at the heart of the investment boom.

Hardware makers including data storage companies like Sandisk, Western Digital, and Seagate Technology Holdings, as well as DRAM maker Micron — some of the best-performing stocks in the S&P 500 this year — were taking a licking, as were networking stocks Cisco and Arista Networks and data center builders such as Vertiv Holdings and electrical and mechanical contractor Emcor.

Optimism for all things AI has seemed to evaporate throughout the week, as the stock market greeted lackluster quarterly numbers from Oracle and Broadcom with jittery sell-offs and concern about growing debts that could crater cash flows.

Those worries seem to be spreading to ancillary beneficiaries of the AI boom on Friday, gouging a chunk out of charts that retail dip buyers have not — at least so far — stepped in to buy as we head into the weekend.

Oracle denies Bloomberg report that it’s delaying some data centers for OpenAI to 2028 from 2027

Getting a multi-hundred-billion-dollar backlog for cloud computing revenues from data center projects is easy. Building them is hard.

Oracle extended declines to as much as -6.5% on the day on the heels of a Bloomberg report that the cloud giant has pushed back the completion dates for some of the data centers it’s building for OpenAI to 2028 from 2027, citing people familiar with the work. Oracle denied this report, telling Reuters that there have been no delays to any sites required to meet its contractual commitments and that all milestones remain on track.

Shares had fully pared their report-induced drop ahead of Oracle’s reply, but remain in the red for the day.

Bloomberg said the reported postponement was attributed to labor and material shortages.

Oracle has been spending more on capex than Wall Street had anticipated, leading to higher-than-expected cash burn. Management boosted its full-year capital spending plans by $15 billion after reporting Q2 results earlier this week.

Oracle’s cloud infrastructure sales came in short of estimates in its fiscal 2026 Q2, a signal that markets already had reason to doubt its ability to quickly turn its humungous RPO (that is, remaining purchase obligations) into revenues.

Traders also seem to be of the mind that potential delays to data center completions are going to limit sales for what goes into them.

Some of the bigger losers since the Bloomberg headline hit the wires include:

Broadcom’s post-earnings tumble is weighing on Google’s entire AI ecosystem

Broadcom’s post-earnings plunge is prompting a sharp pullback in Google-linked AI stocks, which had been on fire thanks to the warm reception to Gemini 3.
