New York, February 10, 2026, 10:08 ET — Regular session
Datadog shares jumped 14.5% to $130.56 on Tuesday after the cloud security and monitoring firm topped quarterly estimates and pointed to demand linked to AI workloads. “During 2025, we delivered over 400 new features and capabilities,” CEO Olivier Pomel said. 1
The burst of buying showed how twitchy the AI trade still is. Investors have been punishing spend-heavy names for weeks, then snapping up anything that looks like real usage, or at least a cleaner story.
Alphabet said it sold $20 billion of bonds to help fund surging AI infrastructure spending, adding to a shift by Big Tech toward debt markets after years of leaning on cash flow. “Century bonds are usually the preserve of governments or regulated utilities,” said Lale Akoner, global market analyst at eToro, after reports Alphabet may also attempt a sterling deal that could include a rare 100-year bond. 2
Analysts at Barclays expect overall U.S. corporate bond issuance to reach $2.46 trillion in 2026, Reuters reported, with hyperscalers racing to expand data centers and buy processors. “AI seems to have gone and dug new sources… and eaten in to cash flows of software companies,” said Karthik Nandyal, co-founder of CredCore. 3
Wall Street’s main indexes opened modestly higher on Tuesday, extending a tech-led rebound from the prior session. The Dow rose 0.11% at the open, the S&P 500 gained 0.14% and the Nasdaq added 0.14%. 4
Cisco rose 1.5% to $88.06 after it unveiled its Silicon One G300 “switch” chip — the networking silicon that steers data inside a data center — and a router aimed at AI clusters. The chip, due in the second half, uses TSMC’s 3-nanometer process and adds “shock absorber” features to keep AI networks from bogging down during traffic spikes, Cisco executive Martin Lund told Reuters; Cisco says it can speed some AI jobs by 28%. Broadcom was up 0.4% and Nvidia slipped 0.3%. 5
Cadence Design Systems gained 2.4% to $298.10 after it introduced an AI “agent” — software that can take on tasks like a junior engineer — to help speed chip design work for customers including Nvidia. “We rent you virtual engineers,” Cadence’s Paul Cunningham said, while analyst Dave Altavilla warned the tools matter in U.S.-China tech competition: “You need that capability to compete.” 6
Policy risk stayed in the background. A Financial Times report said the Trump administration plans to spare firms including Amazon, Google and Microsoft from upcoming chip tariffs tied to AI data-center builds, though the plans remain in flux, Reuters reported; Alphabet fell 2.2%, Microsoft rose 1.4% and Amazon was little changed. 7
Micron fell 2.3% to $374.58 as investors fretted over competition in high-bandwidth memory — the premium DRAM stacked close to AI processors — after reports tied Samsung and SK Hynix more closely to Nvidia’s next-generation systems. Analysts cited by MarketWatch said the anxiety may be overdone, but the stock has been reacting sharply to any hint of supplier shifts. 8
But the downside case has not gone away: AI infrastructure is turning into a multi-year, debt-backed build-out, and the market is still arguing over how quickly that translates into profit. Competition is also stacking up — in networks, chip tools and memory — and it can take only one guidance cut or one customer pause to reprice the group.
Next up, investors will get Cisco’s fiscal second-quarter results on Feb. 11 after the close. Nvidia’s next earnings are scheduled for Feb. 25, a key checkpoint for expectations around AI servers and the supply chain that feeds them. 9
