Fourth quarter earnings have slowed to a trickle after the blowout report from Nvidia (NVDA) capped results for the "Magnificent Seven" tech stocks.

With just 4% of S&P 500 companies left to report results, the index is tracking a 14.2% earnings growth rate for the quarter, which would mark the S&P 500's fifth consecutive quarter of double-digit earnings growth.

Nvidia's report was the marquee event this week, offering a crucial update on demand for high-tech AI chips β€” a big part of the hundreds of billions of dollars its Big Tech peers are spending on AI investments. Salesforce (CRM), Home Depot (HD), and Lowe's (LOW) were among the notable companies reporting this week as well.

In the week ahead, a mix of retail companies, including Target Corporation (TGT), plus a number of others, such as CrowdStrike (CRWD), Broadcom (AVGO), Costco (COST), and Alibaba Group (BABA), will help round out the quarter.

Block (XYZ) shares surged more than 22% in extended trading after Jack Dorsey announced the payments company would lay off nearly half of its staff as part of a major bet in artificial intelligence that came alongside the release of its fourth quarter earnings report.

"Today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. That means over 4,000 of you are being asked to leave or entering into consultation," Dorsey wrote in a post on X.

"Something has changed," Dorsey wrote, framing the decision as a risk intended to position the company for long-term growth. He cited new artificial intelligence tools that can automate work as the reason for the shift, noting that AI is "enabling a new way of working which fundamentally changes what it means to build and run a company."

In the fourth quarter, Block reported adjusted earnings per share of $0.65, in line with Wall Street estimates. Revenue of $6.25 billion slightly beat expectations of $6.21 billion, according to S&P Global Market Intelligence.

Block also raised its full-year guidance. The company, which supports the CashApp and Square platforms, said it expects gross profit growth of 18% year over year in 2026 and adjusted operating income of $3.20 billion or 26% margin.

Duolingo (DUOL) stock plummeted as much as 25% on Friday after the company offered downbeat guidance for 2026 despite beating analysts' expectations on Q4 earnings. The company said it's shifting focus from monetizing its language-learning app to growing the subscriber base.

While daily active users and subscriptions were up 30% and 28% year over year, respectively, that growth slowed throughout 2025 and is expected to decelerate further this year.

CEO Luis Von Ahn told Yahoo Finance on Friday that more than 15 million people have a Duolingo streak longer than 365 days, and growing that dedicated user base is a priority. Von Ahn said artificial intelligence is a major driver of the company's pivot to user growth.

"We think that over the next few years, the way people learn is going to change quite significantly," Von Ahn said, adding that "the most important thing we can do is capture as much of the market as we can, entice as many users to use Duolingo as possible … and we're prioritizing that pretty much above everything else."

Duolingo reported fourth quarter revenue of $282.9 million, up 35% year over year and ahead of the $275.74 million estimated. Adjusted earnings per share came at $0.84, versus the $0.83 estimate. The company's 2026 outlook, however, landed well short of the $1.26 billion estimated, with full-year revenue guidance of $1.20 billion-$1.22 billion.

Flutter Entertainment's (FLUT) stock fell 12% before the bell on Friday after reporting disappointing revenue. The sports-betting operator reported revenue of $4.74 billion last quarter, below the $4.93 billion projected by analysts.

Nvidia CEO Jensen Huang said the company is "close" to finalizing its agreement with OpenAI (OPAI.PVT)

"We continue to work with OpenAI toward a partnership agreement, and believe we are close," Huang said. "We are thrilled with our ongoing partnership with OpenAI, a once-in-a-generation company we've had the pleasure of partnering with since their first days."

In September 2025, Nvidia said it planned to invest $100 billion in OpenAI to support artificial intelligence infrastructure. But in early February, Huang said that the $100 billion was β€œnever a commitment,” and a few weeks later, the Financial Times reported that the company was close to finalizing a $30 billion deal to replace the $100 billion one.

On the earnings call, Nvidia executives touted that "just about every startup in the world is working on Nvidia's ecosystem." The company has also struck partnerships with rival models, including Anthropic's Claude and Google's Gemini.

Nvidia's (NVDA) CFO Colette Kress confirmed a report earlier this week that it has not yet sold any of its second-most-powerful chips to China.

"While small amounts of H200 products for China-based customers were approved by the US government, we have yet to generate any revenue, and we do not know whether any imports will be allowed into China," Kress said on the earnings call.

That was in line with what a Commerce Department official said at a congressional hearing on Tuesday.

President Trump gave Nvidia the green light to sell H200 chips to China last month. In late January, Beijing reportedly gave three of China's largest tech companies, ByteDance, Alibaba (BABA, 9988.HK), and Tencent (0700.HK, TCEHY), approval to purchase more than β€Œ400,000 H200 chips.

CFO Colette Kress called out that the hyperscalers β€” Big Tech firms like Amazon (AMZN), Microsoft (MSFT), and Meta (META) that provide large-scale cloud services β€” continue to have a strong appetite for Nvidia's data center chips.

"Analysts expectations for 2026 capex across the top five cloud providers and hyperscalers, who collectively account for a little over 50% of our data center revenue, are up nearly $120 billion since the start of the year and approaching $700 billion," Nvidia CFO Colette Kress said on the earnings call. "We continue to expect the transition of classic data center workloads to GPU-accelerated computing and the use of AI to enhance today's hyperscale workloads and contribute toward roughly half of our long-term opportunity."
