What believers are saying

  • Oracle's Q1 FY2026 revenue rose 30% to $19.3 billion, signaling strong demand.
  • OpenAI-related demand and Stargate data-center buildouts support OCI growth through 2027.
  • Oracle raised FY2027 targets to $90 billion, implying management sees sustained acceleration.

What critics are saying

  • EU regulators started reviewing Oracle licensing on September 1, 2026; SAP-like remedies follow.
  • Fiscal 2026 free cash flow was negative $23.7 billion after $55.7 billion capex.
  • Oracle's dependency on massive AI buildouts and OpenAI-style contracts creates existential financing pressure by 2027.

What makes Oracle unique

  • Oracle's 2026 RPO hit $638 billion, dwarfing annual revenue and rivals' backlogs.
  • Oracle Database and OCI combine software lock-in with cloud migration paths across enterprises.
  • Oracle's March 2026 AI Database innovations strengthen vector and agentic workloads on-premises and cloud.

Oracle beats earnings estimates with sales rising 30% to $19.3B

Oracle reported fiscal first-quarter earnings of $1.92 per share, surpassing analyst estimates. The enterprise software company's sales climbed 30% to $19.3 billion during the quarter. The strong results demonstrate continued growth for Oracle as businesses invest in cloud infrastructure and database services. The earnings beat suggests the company is maintaining momentum in its cloud computing business. Oracle's performance comes amid ongoing competition in the enterprise software and cloud services market. The 30% revenue increase represents significant year-over-year growth for the tech giant.

Oracle faces earnings tonight with 79% beat probability despite 52% stock decline since last year's 36% post-earnings surge

Oracle reports earnings today with shares down 18% year-to-date and trading around $159, roughly 52% below last September's post-earnings close of $328. The stock surged 36% in a single session following last year's report. Despite the decline, fundamentals remain strong. The company guided first-quarter revenue growth of 27% to 29% and cloud revenue growth of 58% to 64%. Remaining performance obligations reached $638 billion, up 363% year-over-year, with $75 billion tied to GPU arrangements. Options traders are selling calls at the $150 strike, and implied volatility sits at 73, among the highest in the S&P 500. However, 36 analysts rate the stock a buy with a $241 target, and consensus expects earnings of $1.74 per share on $19.13 billion revenue.

Big Tech burns $13.5B as AI buildout sends Treasury yields to 4.79%

US Treasury yields near 4.79% reflect strong corporate borrowing for AI investments rather than economic weakness, according to analysts Joel Litman and Rob Spivey. They argue that context matters more than absolute rate levels. Companies borrowing at 5% to fund projects returning 30-40% benefit from current rates, whilst those earning less than borrowing costs face pressure. The analysts note that AI-related corporate debt issuance reached roughly $1.5 trillion this year, driving yields higher. Alphabet posted its first negative free cash flow since 2004, burning $5.9 billion in Q2 as capital expenditure hit $44.9 billion. Amazon swung to negative $7.6 billion on a trailing basis. However, negative cash flow can signal productive investment rather than distress, the analysts suggest.

Oracle and Adobe earnings Thursday: Which AI play offers better value?

Oracle and Adobe report quarterly earnings on Thursday 10 September, offering different angles on AI investment opportunities. Oracle expects fiscal Q1 revenue of roughly $19.13 billion, up 27%-29% year-over-year, driven by cloud infrastructure demand. Total cloud revenue is forecast to surge 58%-64%, with remaining performance obligations soaring 363% to $638 billion due to large-scale AI contracts. Adobe anticipates fiscal Q3 revenue of $6.69 billion, representing approximately 12% growth. The company recently reported AI-first annual recurring revenue tripled year-over-year to over $500 million, with record Q2 revenue of $6.61 billion. Oracle benefits from AI-related cloud infrastructure demand, whilst Adobe embeds generative AI throughout its creative, document, and marketing platforms. Investors will watch whether Oracle's growth justifies its premium valuation or Adobe's discounted stock offers better value.

Options traders bet Oracle could jump 8% as AI cloud growth faces capital spending scrutiny

Options traders are positioning for significant movement in Oracle shares ahead of the company's fiscal first-quarter earnings report on Thursday. The stock closed at $162.52 on Tuesday, with call options showing particular interest in the $175 strike price — representing nearly an 8% premium. Oracle's cloud infrastructure revenue surged 93% to $5.8 billion last quarter, driven by AI-related demand. The company ended fiscal 2026 with $638 billion in remaining performance obligations, indicating substantial contracted future business. However, aggressive AI data centre investment has strained finances. Whilst Oracle generated $32 billion in operating cash flow in fiscal 2026, free cash flow turned negative at $23.7 billion due to heavy capital spending. Investors will scrutinise whether AI cloud revenue growth can justify the significant infrastructure expenditure.
