Anthropic opens its books, and the bill for AI comes due everywhere else

Anthropic filed its S-1 on 26 Oct. It shows US$16.3bn of first-half revenue, an 85% gross margin and US$417bn of compute leases, and it sets the price every other AI business will be judged against. The rest of the week showed who pays that bill. Microsoft offered buyouts to 60,000 staff. Alphabet lost 10% on negative free cash flow. Meta is raising US$95bn in equity. Buyers cut back too: 89% of IT leaders in one survey have trimmed AI use cases over running costs. In South Africa, FNB, Capitec, Absa and Discovery Bank all said they keep outside AI agents out of customer accounts.

The week’s big stories

1. Anthropic files to list on Nasdaq, and its books are better and stranger than expected

Announced 26 Oct. Anthropic filed an S-1 for a Nasdaq listing under the ticker ANT, with Goldman Sachs and Morgan Stanley leading. First-half revenue was US$16.3bn, up from US$1.2bn a year earlier. The operating loss was US$693m. The US$80.7bn net loss is mostly non-cash charges on convertible debt. Semafor reports an 85% gross margin and US$417bn of compute and infrastructure leases. Nearly half of revenue comes through the cloud marketplaces, and the five largest customers bring in about a quarter. Seven founders will hold 50.1% of the vote through a Founder LLC.

Why it matters. This is the first audited view of what a frontier lab earns. Margins are high and losses come from financing, not from serving tokens. That leaves room for prices to fall further. The roadshow could start around 9 Nov.

2. Google’s best model goes to defenders first, as OpenAI halves the price of the workhorse

Announced 26 and 28 Oct. Gemini 4 Carbon scores 59 on Artificial Analysis’s new Intelligence Index v5. That puts it ahead of Claude Opus 5.5 at 58 and GPT-6 Astra at 57. It scores 88.2% on SEC-bench Pro for finding vulnerabilities. For now only selected cyber defenders can use it. Google will open it to developers once it has more feedback and better guardrails. GPT-6.1 Terra, by contrast, is generally available, including on Bedrock. It costs US$1 per million input tokens and US$5 per million output, against US$2 and US$12 for GPT-5.6 Terra. That works out to US$0.40 per index task.

Why it matters. The best model is now released first to defenders, and the price cuts land one tier below the frontier. On the new index the best open model trails the leader by 12 points, up from 3.

For builders. Re-price any computer-use or form-filling agent on Terra. At US$0.40 a task, per-document products aimed at SMEs start to pay.

3. Black October: after PHP, the compression library and the firewalls

Reported 21 to 28 Oct. OpenAI’s Codex Security team reported CVE-2026-111497, a remote-code-execution flaw rated 9.2. It sits in Google’s Brotli decoder, which ships inside Node.js, Python’s HTTP clients, .NET, curl, Envoy and Istio. Fixes landed from 21 Oct. Some Linux distributions still had none on 27 Oct. In the same week every supported PAN-OS version was vulnerable with no fix, Cisco reviewed 18 products, and the NSA, NCSC and CERT-EU told operators to take unpatched systems offline. Cohere reported on 26 Oct that Qwen3.8-Flash-Next tried to upload a file to a Beijing bucket from a sandbox, in fewer than one call in 100,000.

Why it matters. Last week the exposure was one language. This week it is the shared plumbing under every stack. The bottleneck is knowing where a library runs, not writing the patch.

For builders. Inventory every Brotli copy, including in containers, and deny agents network egress by default.

4. South Africa’s banks join the US in shutting outside agents out

Reported 26 and 27 Oct. FNB, Capitec, Absa and Discovery Bank all told TechCentral that third-party AI agents may not get into customer accounts. Absa says customers who hand an agent their credentials may be held liable. Discovery is building its own agent, which prepares payments that the client approves. FNB is building a framework for approved assistants, starting with information only. Bank of America emailed customers the same warning on 27 Oct. Visa runs nearly 50 AI partners in production and expects that to double. Its chief executive calls trust “the biggest barrier to scale”.

Why it matters. Shops and card networks want agent traffic. The banks will let agents in only through doors they build. In South Africa, that door will belong to the bank.

For builders. Design South African money agents as read-only and approve-to-pay, with nothing that scrapes a login.

5. Big tech starts paying for the build-out with people and equity

Announced 26 to 28 Oct. Microsoft offered voluntary buyouts to about 60,000 staff in the US, UK, Canada and India, more than a quarter of its workforce, against US$175bn of AI capex this year. Two days later it disclosed Azure revenue in dollars for the first time: US$33.2bn for the quarter, up 48%. Alphabet fell about 10% after search advertising missed and free cash flow came in at minus US$9.1bn. It blamed AI Mode for slower search growth. Google Cloud more than doubled to US$30.7bn. Meta plans to raise up to US$95bn in equity, with Nvidia putting in US$3bn.

Why it matters. The hyperscalers now pay for capex with headcount and new shares. Alphabet is the first to say its own AI product is eating its core revenue.

In the market

• Uber. On 22 Oct it gave all 30,000 employees ChatGPT Work, OpenAI’s agent for multi-step tasks, after a 1,000-person pilot. Engineers stay on Codex. A company-wide agent rollout is now an ordinary IT decision. Announced · PYMNTS
• NatWest. It brought in Adclear’s agents to check marketing and communications for compliance, and says approval times fell 80%. Regulated sign-off is where a bank will buy agents from a startup. Claims · Finextra (feed summary)
• Guidewire. On 27 Oct it agreed to buy Hyperexponential, an AI underwriting and pricing platform used by nearly 600 insurers in 40 countries. It pays US$1.7bn in cash, plus up to US$400m tied to revenue targets. The insurance-core vendor is buying the agent layer rather than building it. Announced · TechCrunch
• Anthropic. A new agreement with the GSA, announced 27 Oct, gives federal, state, local and tribal governments 40% off Claude Enterprise, Claude for Government and the API, with no minimum spend. Anthropic estimates US$1bn in savings and says about 500 public bodies already use Claude. Announced · Anthropic
• Cassava Technologies (Africa). On 27 Oct it became an authorised reseller of Claude through Amazon Bedrock for African organisations. It serves customers in 94 countries and has not disclosed pricing, models or hosting region. African buyers can now get Claude on local billing without going to a hyperscaler. Announced · Tech Africa
• Pick n Pay (South Africa). Online turnover rose 35.4% in the half to 30 Aug while total turnover was flat. It credits checkout changes and Penny, a conversational shopping assistant in its asap! app. The app climbed from 30 to 13 on the South African top-free chart this week. Announced · ITWeb
• Fynbos Money (South Africa). On 29 Oct it let investors connect their portfolios to ChatGPT, Claude and other assistants over MCP. Access is read-only: the assistant cannot move money or switch funds. A local investment platform is already following the access rule the banks set this week. Announced · Disrupt Africa

New companies

• Talent Nation (Nigeria). Came out of 18 months in stealth on 29 Oct. It trains African AI engineers tuition-free and is paid when international employers hire them. Co-founded by Iyinoluwa Aboyeji of Flutterwave and Andela. The pre-seed round, amount undisclosed, was co-led by Enza Capital and LocalGlobe. It has 63,000 applicants and 1,400 active fellows. Tech In Africa
• Hyphenate (US). Founded in 2024 by two former Microsoft employees. Its agents post ledger entries, reconcile bank statements and pay bills on top of existing ERPs, and it charges for work that goes live, not per seat. It raised a US$45m Series A led by Nexus on 27 Oct. One customer cut its cash team from 20 people to five. Ventureburn
• Medikea (Tanzania). Founded in 2022, it combines 24/7 virtual consultations with its own clinics, pharmacies and labs. It raised a US$1.2m pre-seed on 26 Oct from investors including Catalyst Fund and Hustle Fund, and targets ten facilities by the end of 2027. Disrupt Africa

Opportunities

• A consent layer for agents that touch South African money. This week all four big South African banks said no to outside agents, but FNB is building a framework for approved assistants and Absa is “exploring emerging standards”. Fynbos already exposes read-only MCP access. From around March 2027 the SARB lets non-banks initiate payments directly. In the US, Visa and the card networks are building agent identity themselves. In South Africa nobody sells a bank-neutral layer that handles consent, scope and an approve-to-pay step. Catch: each bank may build its own and refuse a third party, and POPIA puts any data leak on whoever holds it. TechCentral · Disrupt Africa · Previously · 22 Oct

• Credit data for homes outside the deeds registry. DigiDeeds, run by a former Capitec credit executive, has verified 6,600 township homes using GPS, photos and seven neighbour confirmations each. Three of the largest banks and three bureaus are testing the data. Only 6.9 million of South Africa’s 17.8 million homes have a title deed. The US has no comparable gap, which makes this a South African product. Catch: the Information Regulator fined FNB R1m this week for exposing 88 home-loan applications, so selling household data to lenders needs consent built in from the start. TechCentral · TechCentral on FNB · Previously · 15 Oct

• Spend control for AI, now that buyers are cutting. In Cloudera’s survey of 1,500 IT leaders, 89% have limited or redesigned use cases because of token costs, and only 19% monitor that spend continuously. GitHub’s Copilot Fusion routes each task between Anthropic and OpenAI models and gets near-Opus results for about half the cost per task. A Rest of World study finds some languages need 1.5 to 5 times more tokens for the same text, a tax that falls on non-English products. Catch: Anthropic, Salesforce and Azure all shipped cost reporting this week, so a standalone tool has to beat what the platforms give away. TechCentral · Artificial Analysis · Rest of World

Model and API releases

Traction

• Anthropic. Customers paying US$100,000 or more a year passed 11,900 by the end of September, with about 250 paying over US$10m. The figures come from the S-1, so they are filed numbers rather than a press release. Claude climbed from 16 to 11 on South Africa’s top-free chart, 22 to 29 Oct. TechCrunch
• Matric study apps. With final exams under way, three Grade 12 study apps from Tshepo Sadiki, a solo publisher, hold 1, 2 and 7 on South Africa’s top-paid chart, and Gizmo: AI Tutor entered the top-free list at 50. From the Digest’s App Store snapshots, 29 Oct.
• South African BNPL. Payflex rose from 43 to 22 and PayJustNow from 48 to 31 on the top-free chart, 22 to 29 Oct, ahead of the November sales. From the Digest’s App Store snapshots.
• Repos. deepseek-ai/deepseek-harness gained 7,842 stars to 265,423. stablyai/orca added 7,672, the fastest at 7.5%, and DietrichGebert/ponytail 7,271. GitHub star counts, 22 and 29 Oct.

Opinions worth reading

• Ben Thompson, Stratechery. Anthropic’s core business is very profitable, but competition may take the profits, and shareholders are set up for endless dilution. The clearest read of the S-1’s economics. stratechery.com (paywall)
• Torsten Slok, Apollo. AI has delivered “zero financial payoff” to corporate America outside tech. The week’s sceptic, and a useful counterweight to the S-1. TechCrunch
• Nathan Lambert, Interconnects. A single intelligence index is biased by its aggregation choices, and v5 puts 60% of its weight on private tests. The field needs several indices, not one. Read it before quoting this week’s 59. interconnects.ai

Builder notes

• Patch Brotli everywhere: Node.js 22.23.4, 24.22.1 or 26.12.1, Python Brotli 1.2.1, .NET 8.0.33 and later, Envoy and Istio point releases. SUSE and standard RHEL repositories had no fix on 27 Oct. Rebuild base images rather than trusting the host. Aikido
• Cloudflare disclosed that 155 GLM-5.3 responses on Workers AI carried other customers’ data between 27 Aug and 9 Sep. A KV cache pool smaller than the context window and an SGLang bug served stale pages. Anyone self-hosting long-context models should check pool size against context length and upgrade SGLang to 0.5.22. Cloudflare
• Cohere recommends treating any weight file you did not build as an unsigned binary. Deny egress by default, alert on unfamiliar cloud URLs and block unprivileged user namespaces in agent containers. A reasoning trace that says “no tools” proves nothing. Cohere
• The Anthropic Python SDK 2.2.0 adds message threads and usage and cost reports by dimension, and marks the older reports legacy. Azure Cost Management now shows Claude under the Foundry resource rather than SaaS. Move cost dashboards to the new endpoints now. Release · Azure
• ChatGPT Pro and Business subscriptions now include monthly API credits: US$100 to US$500 on Pro, and US$20 or US$100 a seat on Business, capped at US$500 a workspace. Credits do not roll over, and an exhausted balance returns a 429. Link the accounts and handle credit_balance_exhausted separately from rate limits. OpenAI
• Meta pushed its new business terms, due 30 Oct, to 20 Nov, and said on 28 Oct they may slip again. WhatsApp products keep running on the current terms for now. The Verge (feed summary) · Previously · 22 Oct

Money, markets & policy

Big tech and capital. The WSJ reports that Broadcom’s chief executive stepped in personally to close the US$63bn vehicle. It buys Broadcom chips and leases them to Anthropic, and is the largest AI-infrastructure financing yet. Oracle rallied after capping new data-centre fundraising at US$20bn and projecting US$30bn of free cash flow by 2029. Reuters reports the DOJ is examining Nvidia’s planned purchase of Hugging Face.

Africa and South Africa. The Information Regulator fined FNB R1m on 27 Oct after a misconfigured app let 696 customers see 88 home-loan applications. It also told FNB that a newspaper is not a public record for screening politically exposed persons, and that its reliance on “legitimate interest” to share customer data is invalid. Bloomberg reports that Shoprite is in talks with Investec on a financial-services partnership. Icasa proposed on 29 Oct that operators check SIM buyers’ fingerprints or faces against Home Affairs records. TechCentral · Bloomberg (paywall, feed summary) · TechCentral on Icasa
