Enterprise AI software stocks surged Wednesday, led by monday.com's 9.7% gain and a broad rally across SaaS and data names, as softer-than-expected producer prices drove the S&P 500 to a record close of 7,798.99. The Nasdaq Composite gained 0.81% to 26,803.03, the SOXX semiconductor ETF added 0.76% to 550.74, and growth stocks broadly benefited as the case for rate relief strengthened on the cool PPI print, per Bloomberg.

monday.com surges 9.7% as Q2 earnings resonance builds
monday.com Ltd. (NASDAQ: MNDY) posted its sharpest single-day gain in months, closing at $94.29 after the work-management software company reported second-quarter 2026 results on August 10. Analysts had expected revenue of approximately $362 million, representing roughly 18.8% year-over-year growth; the prior quarter delivered $351.3 million, beating consensus with 24.5% growth. The stock spent the sessions after the print absorbing the result, and the combination of a confirmed beat and Wednesday's macro relief trade pushed shares up 9.7%. monday.com's mondayAI suite, which brings agentic workflow automation to its Work OS platform, is the multi-quarter thesis investors are pricing. At $94.29 the stock is still down 34% year to date, which means buyers today are getting in well below where they started the year, even as the underlying revenue trajectory has been accelerating.

MongoDB gains 7.9% as AI data infrastructure demand sustains momentum
MongoDB Inc. (NASDAQ: MDB) extended its post-earnings run, closing at $472.29 for a 7.87% gain on Wednesday. The company's first-quarter fiscal 2027 results, reported earlier this month, showed revenue of $688 million growing 25% year over year and beating management's own guidance, according to TIKR. The next print is August 27. Today's move looks like a combination of sector rotation into AI data names, the rate-relief tailwind from soft PPI data, and accumulation ahead of what investors hope will be a second consecutive beat. MongoDB is up 43.7% over the past month and 18.2% year to date, and it remains among the AI stocks to watch in the data-infrastructure tier: its document-database architecture sits at the centre of most AI application stacks, and management has been guiding to an accelerating Atlas cloud business as inference workloads scale.
Cloudflare extends its post-earnings climb with a 6.2% advance
Cloudflare Inc. (NYSE: NET) added 6.22% on Wednesday, closing at $330.83, as investors continued to reward the company for its blowout second-quarter results delivered August 6. Revenue grew 36% year over year to $696.1 million, and non-GAAP earnings per share of $0.29 beat the $0.21 consensus by 38%, per StockStory. Management lifted full-year revenue guidance to a $2.87 billion midpoint, 2.1% above prior estimates. CEO Matthew Prince highlighted record growth in total paying customers, large customers, and developers. Cloudflare absorbed a $150.7 million restructuring charge tied to what Prince described as a shift to an "agentic AI-first" operating model, reorganising its sales force around AI-agent use cases. The macro tailwind from the PPI print layered on top. Cloudflare is now up 21.4% for the month and 68.8% year to date.
Datadog rises 4.7% on AI observability demand
Datadog Inc. (NASDAQ: DDOG) gained 4.70% to close at $252.24, contributing to a 7.8% weekly advance. The AI observability thesis is straightforward: as enterprises deploy more AI agents and inference pipelines, the need to monitor those systems in real time grows proportionately, and Datadog is the dominant tool for that job. AI infrastructure stocks like DDOG are most directly levered to the scale-out of AI workloads at the hyperscaler tier. At $252.24 the stock is up 88.6% year to date, one of the strongest performers in the sector. The next earnings catalyst is not yet scheduled; consensus is watching for any mid-quarter data points on enterprise AI spending to calibrate the next leg.
