A quick and dirty timeline of the market’s DeepSeekFreak

That escalated quickly.

Mega tech stocks plunged in their worst sell-off of 2025 early Monday, with AI darlings like Nvidia, Palantir, and Broadcom notching some of their biggest stumbles in recent memory.

Associated AI plays, like the energy companies that have soared on expectations of endless power demand for massive data centers, think Vistra and Constellation Energy are getting absolutely smoked.

The catalyst for the cataclysm arose over the weekend, as the US tech cognoscenti began to grow convinced that a new model called R1 released by DeepSeek, the Chinese artificial intelligence company, seemed to pose a major strategic threat to AI arms-race strategy pursued by US tech giants, and by extension, the massive market rally for companies like Nvidia that have been at the heart of this boom.

Here’s a quick refresher on what happened.

“DeepSeek, a startup funded by quantitative hedge-fund manager High-Flyer, also officially unveiled its own large language model, R1. DeepSeek claims its performance is on par with OpenAI’s reasoning model, o1.”

“Part of the buzz around DeepSeek is that it has succeeded in making R1 despite US export controls that limit Chinese firms’ access to the best computer chips designed for AI processing. ‘The fact that it comes out of China shows that being efficient with your resources matters more than compute scale alone,’ says François Chollet, an AI researcher in Seattle, Washington.”

DeepSeek said training one of its latest models cost $5.6 million, compared with the $100 million to $1 billion range cited last year by Dario Amodei, chief executive of the AI developer Anthropic, as the cost of building a model.”

DeepSeek has integrated the reasoning model into the web and app versions of its chatbots for unlimited use at no cost.

In comparison, OpenAI charges US$200 per month for unlimited access to its o1 models, or a minimum of a US$20 monthly fee for a standard plan that includes limited access.”

“‘The bottom line is the US outperformance has been driven by tech and the lead that US companies have in AI, Lerner said in a note to investors Monday morning. The DeepSeek model rollout is leading investors to question the lead that US companies have and how much is being spent and whether that spending will lead to profits (or overspending).’”

If a top-end model costs millions of dollars, not hundreds of millions or billions, and an API can be offered at 27 times less than what is being sold by OpenAI, the massive expense of the past two years may have been wasted... If what DeepSeek says is true and can be replicated, the catalyst driving the AI bull market would quickly reverse, and could even lead to a market crash.

TechCreate keeps going parabolic and the company doesn’t know why

Singapore-based payment software company TechCreate mooned on Thursday, rising 889% and prompting management to issue a statement that “it is not aware of any material nonpublic information that has not been publicly disclosed that would account for the recent trading activity.”

This no news momentum is continuing: shares are up more than 100% in premarket trading on Friday, as of 5:30 a.m. ET. All told, some $280 million changed hands in the stock in US trading yesterday, roughly 24 times its average volume from the previous 20 sessions.

As of mid-January, roughly one quarter of the stock’s float was sold short, per data from Bloomberg, and that float makes up only about 15% of shares outstanding.

Can’t say I remember the last time I’ve seen a $150 million market cap company turn into a $3 billion market cap company in under 24 hours.

GameStop CEO Ryan Cohen is eyeing what he says could be a “genius or totally, totally foolish” major acquisition

GameStop CEO Ryan Cohen told The Wall Street Journal that he’s on the hunt for a “big” acquisition in the consumer or retail industry that would ultimately either “be genius or totally, totally foolish.”

During his tenure atop the company, Cohen has been successful in trimming costs and growing the company’s collectibles business. But the potential for him to pursue a “transformative” acquisition — buoyed by all the money the company was able to raise during episodic meme stock rallies — has been cited as a key pillar of the bull case by its investors, including Keith Gill aka Roaring Kitty and Michael Burry of “The Big Short” game, who recently announced that he’s long the stock.

GameStop has recently shifted its crypto holdings from cold storage to Coinbase Prime, which may also hint at a plan to boost liquidity through crypto sales to pursue M&A opportunities. Shares are up 2% as of 4:13 a.m. ET on Friday.

Cohen has a strong incentive to shoot for the moon:

The CEO recently agreed to a package that would tie his pay completely to the company’s market value and the amount of cumulative earnings before interest, taxes, depreciation, and amortization that the company generates under his leadership.

The proposed deal would see Cohen start to receive stock options in the event that GameStop’s market capitalization exceeds $20 billion while also booking $2 billion in cumulative EBITDA from Q1 2026 onwards.

On a closing basis, GameStop has exceeded this $20 billion threshold only during its 2021 meme stock mania. And, due to heavy losses from 2019 through early 2022, it's taken GameStop a full decade to generate its latest $2 billion in cumulative EBITDA.

Cohen’s pay package has yet to be approved by shareholders, but he’s not waiting for the green light to increase his financial ties to the retailer he runs. Last week, he purchased 1 million shares of company stock for roughly $21.4 million, and opined that any CEO who fails to buy their stock in the open market with their own money should be fired.

Meanwhile, Monday’s revelation that Burry is a GME owner spurred the most retail buying of GameStop shares since late Q1 2025, when the company unveiled its bitcoin treasury strategy, per JPMorgan.

Microsoft shares have biggest single-day drop since March 2020

Yesterday, Microsoft reported strong earnings and revenue for its second quarter, but the stock plunged after-hours. Investors seem to have been concerned about so much of Microsoft’s booked contracts coming from one company — OpenAI — as well as its slowing cloud growth.

Today, it got worse. Microsoft shares sank 10%, suffering their largest single-day drop since the start of the Covid lockdown in March 2020.

Western Digital beats Wall Street estimates for Q2 sales, EPS

Western Digital posted better-than-expected quarterly sales and earnings-per-share figures after the close Thursday, though the shares slipped after-hours. 

Here’s how the results looked:

  • Fiscal Q2 revenue of $3.02 billion vs. the $2.93 billion consensus analyst expectation, per FactSet.

  • Adjusted earnings per share of $2.13 vs. the $1.93 analysts predicted.

  • Fiscal Q3 guidance for adjusted EPS of $2.15 to $2.45 vs. analyst estimates of $1.99.

  • Guidance for Q3 sales of $3.1 billion to $3.3 billion vs. estimates of $2.98 billion.

Western Digital — and rival Seagate Technology Holdings — were among the market’s best performers last year, rising 282% and 219%, respectively, as data storage became a key bottleneck for hyperscalers. 

The shares are romping into 2026 as well, with both stocks up more than 60% in January through the close of trading on Thursday.
