Stock Market Today (LIVE): DDOG Surpasses $1 Billion and Is Accelerating; Will Iran Talks Save the Market?

4:28 pm — DDOG +31.33% today (-1.03% after hours)

The monitoring software company didn’t just hit a milestone this quarter, it announced that its best days might still be ahead. Datadog (DDOG +31.29%) posted Q1 2026 revenue of $1.006 billion, up 32% year-over-year and a full acceleration from last quarter’s 29% growth. Non-GAAP earnings of $0.60 per share blew past the $0.52 consensus estimate, and the company raised full-year revenue guidance to $4.30–$4.34 billion. The market responded with a 24% single-day stock surge, one of the bigger post-earnings pops you’ll see from a company already this large.

The AI story is no longer theoretical. Some 6,500 Datadog customers are now running AI integrations through the platform, representing roughly 80% of the company’s annual recurring revenue. Enterprise deal velocity exploded: 11 contracts worth more than $10 million in total contract value closed this quarter, versus just one in the same period a year ago. Remaining performance obligations grew 51% year-over-year to $3.48 billion, meaning future contracted revenue is piling up fast. CEO Olivier Pomel framed it simply: more AI means more complexity, and more complexity means more Datadog.

The bull case practically writes itself: re-accelerating growth, deepening enterprise relationships, and a platform expanding into security, developer tools, and agentic AI (its new Bits AI SRE Agent charges per investigation, opening a fresh monetization layer).

The bear case is mostly the stock itself. After a 24% pop, Datadog is priced for continued perfection. A growth hiccup, or optimization from the handful of massive AI labs now driving a growing slice of new business, and that premium unwinds quickly.

Markets are retreating from yesterday’s record highs as oil hovers near $100 and traders watch for signs the Middle East war may be nearing an end. U.S.-Iran talks could resume as early as next week, with the fate of the Strait of Hormuz hanging in the balance. Tech held up: Nvidia (NVDA +1.77%), Microsoft (MSFT +1.69%), and Tesla (TSLA +3.14%) each gained more than 1%, keeping the Nasdaq near record territory. Most other sectors fell, pulling the Dow and S&P 500 lower. The 10-year Treasury yield climbed to 4.393%.

3:15 pm — +26.07%

SiTime (SITM +27.90%) has done it again! The market is celebrating the precision timing semiconductor specialist’s earnings results with a 31% spike this morning. SiTime has been guiding for a 5-Year revenue CAGR of 35% (something I had never seen in other stocks I follow), and they are actually delivering. Q1 results showed saled soared by by an astounding 88%, with gross profits jumping even higher by 120% YoY to a gross marging of 59%.

SiTime has been securing design wins for its durable and precisie timing MEMS solutions against legacy rivals. Data centers have added a new tailwind for the company, and their recent acquisition of Renesas’ (RNECY +4.77%) timing business has catapulted that data center exposure, and rounded up their timing solutions to effectively become a one-stop shop.

SiTime is in a league of its own from a products and execution perspective. They have effectively carved out a niche, and they have been the top dog and leader in it. Of course, semis can be notoriously cyclical, so I would only add cautiously at these levels.

2:51 pm — PLNT -31.43%

Planet Fitness (PLNT 31.19%) is having a rough Thursday — shares cratered 33%, on pace for the stock’s worst single-day drop ever, after the gym chain slashed its 2026 outlook and scrapped a planned price hike. New Year’s signups — typically the chain’s most important growth period — came in light, and CEO Colleen Keating didn’t sugarcoat it: "We may have pivoted too far." Translation: in trying to court fitter, wealthier gym-goers, Planet Fitness may have spooked the budget-conscious beginners who made it famous.

2:21 pm — MCD +0.079%; SHAK -28.78%

McDonald’s (MCD 0.14%) posted Q1 revenue and profit above estimates, with U.S. same-store sales up 3.9% — and the secret sauce is no secret at all: cheap food. The burger giant has spent two years hammering its value menu, and with consumers feeling the pinch from rising gas prices and general economic gloom, that bet is paying off. CEO Chris Kempczinski put it plainly: "You need in this environment value and affordability to be a strength." Hard to argue with that.

1:10 pm -- AMZN -0.8%

Amazon (AMZN 1.40%) said its pharmacy will stock Novo Nordisk's (NVO +0.02%) new Ozempic pill for type 2 diabetes at its kiosks and offer same-day delivery, expanding the e-commerce giant's footprint in fast-growing GLP-1 medications.

12:20 pm -- TEAM +5.5%

By Yasser El-ShimyTeam Rule Breakers

The Australian company behind your company's favorite (and occasionally cursed) productivity tools is transforming into something far more interesting: an AI-powered enterprise juggernaut that's quietly becoming indispensable to the modern workplace.

Atlassian's (TEAM +4.04%) quarter in a nutshell? Exceptional.

Cloud revenue hit $1.13 billion, up 29% year-over-year, while remaining performance obligations -- essentially future contracted revenue -- surged 37% to $4.0 billion. That's not just growth; that's enterprises locking themselves into Atlassian for years to come. Free cash flow clocked in at $561 million, good for a 31% margin. For a company still investing aggressively in AI, that's a remarkably healthy engine running under the hood.

But the real story is Rovo.

Atlassian's AI product is becoming a genuine expansion catalyst.

12:05 pm -- SEZL +19.8%

By Matt Frankel, CFP®Team Hidden Gems

Sezzle (SEZL +15.96%) delivered the kind of quarter that justifies the run-up its stock had been on heading into the print, with both growth and profitability accelerating at the same time. Revenue climbed 29% to $135.5 million and beat consensus by about 5%, while adjusted EPS of $1.43 jumped nearly 46% year over year and topped estimates by roughly 16%. The combination matters because it shows the buy-now-pay-later platform, which lets shoppers split purchases into interest-free installments, is scaling without sacrificing margins.The engine behind the quarter was a 48% surge in active subscribers, driven by a marketing pivot toward paid memberships like Sezzle Premium and Sezzle Anywhere that lock in higher-value users.

11:10 am -- ANET -2.3%

By Seth JaysonTeam Rule Breakers

Arista Networks' (ANET 3.62%) numbers were genuinely good with 35% revenue growth, beats on both earnings and revenue yet the stock dropped roughly 15% anyway, because investors wanted a bigger guidance bump. ("Why did the stock drop on such great news?" "Because it's a stock...") The CEO said this is the best demand environment she has ever seen in her tenure at the company, but Arista can't source enough chips, optics, and memory to fill all its orders. That's a maddening constraint, but it's also a fairly unusual problem to have, rather it used to be. Arista has always been a favorite of mine for its ability to actually produce free cash flow (while many peer companies grow 'n' burn). They spend some (but not even most) of this FCF buying back shares, which has kept the share count static (rewarding whom exactly?) but again, unlike many peers, who plow all their FCF into share buybacks, outside shareholders can see the FCF actually helping them, rather than being laundered back into employee comp.

10:05 am -- WHR -11.9%

By Matt ArgersingerTeam Rule Breakers

For Whirlpool (WHR 11.91%) it has been a parade of red flags the last couple of years:

Unfortunately, the kitchen and bathroom appliance maker's first-quarter results only deepened the misery for investors. Lower sales volumes and a near complete collapse in profitability in the company's major domestic appliance business contributed to a major earnings miss, a slashed full-year outlook, and, gulp, a dividend suspension. As I write, shares are down more than 20% in pre-market trading.At this point even a long-overdue recovery in the U.S. housing market -- my top (and really only) reason for continuing to assign any hope for the company looks like it won't be a panacea for Whirlpool's many ills. The balance sheet is still loaded with debt; savings from the dividend and planned price increases should boost cash flows in the short term, but improvement to margins and profits might be short-lived if sales volumes continue to struggle. At the same time, any benefits from new tariff policies designed to insulate domestic manufacturers aren't likely to help the company overcome a decidedly weak long-term competitive position vis-a-vis its low-cost Asian competitors.

10:00 am -- AMD -1.9%

By Tim BeyersTeam Rule Breakers

Large-scale spending on chips and systems supporting AI is unlikely to slow soon. That's how I read the inventory data reported by Advanced Micro Devices (AMD 3.05%) last night.

As a percentage of its $8.045 billion worth of inventory on hand at the end of Q1, 31.6% was finished goods. Only 9.3% was raw materials.

At the same point last year, 8.7% of AMD's inventory was registered as raw materials while 21.1% was finished goods.

AMD is working feverishly to bring more chips to market, faster. CEO Lisa Siu would only commit to bigger chunks of finished goods inventory if demand for her company's products was spiking rather than moderating.

It's unclear whether institutional investors are paying attention to the underlying inventory data. I'm not sure it matters. Revenue (up 38%) and per-share profit (up 91%) showed more than enough growth to light up AMD's first-quarter report.

In response, the stock is up over 18% in today's pre-market trading. The surge may also be due to predictions for accelerating growth. Q2 revenue is expected to up 46% year-over-year.

More inventory to meet more demand, in other words.

Nvidia (NVDA +1.77%) still dominates the AI compute market
