New York, February 10, 2026, 10:08 ET — Regular session
Datadog surged 14.5% to $130.56 on Tuesday as the cloud security and monitoring company blew past quarterly expectations, citing a boost in demand driven by AI-related workloads. “During 2025, we delivered over 400 new features and capabilities,” CEO Olivier Pomel said. 1
The sudden rush of buyers underscored just how jumpy the AI trade remains. For weeks, investors dumped stocks associated with heavy spending, only to jump right back in at the first sign of actual adoption—or even just a more straightforward narrative.
Alphabet tapped the bond market for $20 billion, aiming to bankroll its rapidly expanding AI infrastructure—another sign tech giants are turning to debt after years of relying on cash flow. Lale Akoner, global market analyst at eToro, pointed out that “century bonds are usually the preserve of governments or regulated utilities,” commenting after reports surfaced that Alphabet may pursue a sterling issuance with a rare 100-year note. 2
Barclays analysts are projecting $2.46 trillion in total U.S. corporate bond issuance for 2026, Reuters said, as hyperscalers snap up processors and pour money into new data centers. “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
Stocks edged up early Tuesday, with Wall Street’s major indexes nudging higher as tech names picked up where they left off. The Dow was up 0.11% at the bell, while the S&P 500 advanced 0.14% and the Nasdaq mirrored that 0.14% rise. 4
Cisco climbed 1.5% to $88.06 after pulling back the curtain on its Silicon One G300 “switch” chip, a piece of networking silicon built to move data inside data centers, plus a new router for AI clusters. The chip, slated for the second half and built on TSMC’s 3-nanometer process, includes “shock absorber” tech designed to prevent AI networks from stalling during traffic surges, according to Cisco executive Martin Lund in comments to Reuters. Cisco claims the chip can accelerate certain AI workloads by 28%. Broadcom inched up 0.4%, while Nvidia edged down 0.3%. 5
Shares of Cadence Design Systems jumped 2.4% to $298.10 on news the company rolled out an AI “agent” built to tackle engineering tasks—think junior staff—aimed at accelerating chip design for clients such as Nvidia. “We rent you virtual engineers,” said Cadence’s Paul Cunningham. Analyst Dave Altavilla flagged the strategic angle for the U.S.-China tech rivalry: “You need that capability to compete.” 6
Policy risk didn’t take center stage. According to the Financial Times, the Trump administration is eyeing exemptions for companies like Amazon, Google, and Microsoft from new chip tariffs aimed at AI data-center construction—plans still unsettled, per Reuters. Shares reflected the uncertainty: Alphabet dropped 2.2%, Microsoft picked up 1.4%, while Amazon barely moved. 7
Micron dropped 2.3% to $374.58, with investors jittery about competition in high-bandwidth memory after reports linked Samsung and SK Hynix more firmly to Nvidia’s next-gen systems. The high-end DRAM sits right next to AI chips, and even slight supplier rumors have been moving the stock lately. Analysts quoted by MarketWatch argued that concerns might be overblown. 8
Still, risks remain. The AI infrastructure boom is shaping up as a long-haul, debt-fueled build, and investors are far from settled on how fast those dollars turn into actual profit. Competitive pressure is ramping across networks, chip tools, memory. One guidance cut, one big customer hesitating—sometimes that’s all it takes to knock the whole group back down.
Cisco reports fiscal Q2 numbers after the bell on Feb. 11. Nvidia’s turn comes Feb. 25, a date traders are already circling to gauge sentiment on AI servers and the supply pipeline driving them. 9
