Fastly and UiPath offer different paths to AI growth

Fastly and UiPath offer different ways to invest in software and artificial intelligence as 2027 approaches. Fastly runs an edge cloud platform that speeds up and protects websites and apps, while UiPath automates office tasks by coordinating AI agents and people. Fastly reported fiscal 2025 revenue of $624 million, up 14.8%, and a net loss of $121.7 million. UiPath reported $1.6 billion in revenue for its fiscal year ended Jan. 31, 2026, up 12.7%, and net income of $282.3 million. UiPath also reported $352.2 million in free cash flow, compared with Fastly's $65.8 million, though stock-based compensation made up a large share of operating cash flow at both companies.

Six data software companies help businesses use AI

Snowflake, Datadog, MongoDB, Cloudflare, Elastic, and Palantir sell software that supports companies using artificial intelligence. All six grew revenue by at least 15% year over year in their latest reported quarters, and Palantir's revenue nearly doubled. Snowflake's product revenue rose 37% to $1.49 billion in fiscal second-quarter 2027, while MongoDB revenue grew 30% to $771.8 million and the company recorded $40.9 million in net income. Cloudflare revenue increased 39% to $782.5 million, while its gross margin fell and its net loss widened. Elastic's revenue grew 15% to $478 million, and its current remaining performance obligations rose 21%; Datadog's largest customer reduced its use of the platform in the third quarter.

Study finds drug ads can sway AI treatment recommendations

Researchers tested 12 consumer-facing large language models, including versions of Claude, Gemini, and GPT, across 33 medical scenarios. Some tests showed the models an advertisement for one treatment, with details about the drug but no direct request to recommend it. The models recommended the advertised treatment an average of 47.6% of the time when they saw an ad, compared with 35% without an ad. The effect varied across the models, and the study authors said that even a clinically reasonable answer can raise questions about how the AI reached its recommendation.

Financial stocks fall as investors worry about AI spending

Shares of banks and other financial companies fell during turmoil in the technology sector. Strategists said the ouster of Nvidia Chief Executive Jensen Huang clouded the outlook for artificial intelligence and Wall Street firms betting on the technology. Blackstone, a major backer of data centers and AI companies, fell more than 2%, while Blue Owl also dropped sharply. Brookfield reported third-quarter earnings growth, partly helped by inflows into its asset-management business.

Red Hat releases OpenShift 5 with AI agents and stronger security

Red Hat announced the general availability of OpenShift 5, a platform for running AI workloads, virtual machines, and containerized applications across data centers, cloud environments, and disconnected deployments. Organizations can move from OpenShift 4 through an in-place update. The release adds Model Context Protocol server support and upgrades OpenShift Lightspeed from a conversational assistant to an agent that can help troubleshoot problems and assess update risks. It also adds hardened multi-tenant isolation, post-quantum cryptography, and automated checks to help teams manage security and updates in regulated or disconnected environments.

Nvidia’s leadership shakeup could reshape private AI funding

Nvidia plays three major roles in private AI: it is the largest corporate investor in U.S. AI, a key supplier to startups and a benchmark for public investors. A change in leadership could make funding harder for companies that depend on Nvidia, including neocloud firms such as CoreWeave and Lambda Labs. Some investors say a shakeout could curb high valuations and stop money flowing to weak ideas. PitchBook analyst Harrison Rolfes advises startups to focus on buying computing power rather than seeking Nvidia investment, since GPU prices may fall and cheaper chips could help new companies grow.

Data center setbacks in 10 states raise risks for AI companies

Voters in 10 states supported limits on data centers or rejected proposals to build them, while Democrats made gains in the November midterm elections. Redbud Consulting tracked 41 ballot measures, and 40 sought to restrict data centers. The results have raised concerns that a Democrat-led Congress could increase oversight and make construction more costly or slow expansion. From Oct. 30 to Nov. 5, shares of Nebius Group, IREN Ltd, CoreWeave and Applied Digital fell about 27% to 31%, while Nvidia shares dropped about 16% and Alphabet shares stayed relatively flat. OpenAI CFO Sarah Friar said the company remains committed to investing in AI infrastructure, and CoreWeave CEO Michael Intrator said the political changes would not derail expansion plans.

Mirendil raises $1 billion to speed up AI research

Mirendil, a startup developing AI tools to speed up AI research and development, raised $1 billion in a Series A funding round. Kleiner Perkins and Clearlake Capital led the round, the company said Thursday. Less than six months earlier, Mirendil raised a $200 million seed round. The fundraising reflects how venture capital firms are putting large sums into a small group of AI startups.

United moves to block unauthorized personal AI travel agents

United Air Lines is updating its booking, ticketing and distribution policies to restrict unauthorized third-party personal AI agents on its digital platforms and through travel agencies and aggregators. The airline says its app lets customers manage their own travel securely, including booking trips, choosing seats and rescheduling flights. United warns that sharing account credentials with AI assistants could expose private data or lead to unwanted purchases, account changes or use of MileagePlus miles. The company also says automated actions could violate FAA and DOT rules, since some steps, such as flight check-in, require human confirmation about banned items in bags.

Retailer picks HawkSearch for a 180,000-product online catalog

Bridgeline Digital said a major retailer selected its HawkSearch platform to replace its existing enterprise search system. The retailer has about 180,000 products across two divisions, with roughly 90,000 products in each, covering categories such as farm and ranch, home, hardware, outdoor and sporting goods. HawkSearch’s Hybrid Hosting and Unified Search will support product discovery, with dedicated infrastructure and more control over how products and content appear. The retailer will also evaluate additional AI features, while HawkSearch offers intelligent product discovery and conversational shopping capabilities. Bridgeline CEO Ari Kahn said the platform gives the retailer a scalable search system and a path to more AI-powered shopping experiences.
