- Anthropic kicks off mammoth stock market float despite investor jitters
Anthropic filed its S-1 in the US on Monday, setting out its pitch for a first public stock sale expected to be one of the biggest listings in history, with shares to trade on the Nasdaq Global Select Market under the ticker ANT. The move comes amid investor jitters about AI, after shares of 'neocloud' data-centre companies tumbled in recent weeks and Meta shares slumped after it unveiled plans to spend hundreds of billions on the technology. The 335-page filing shows rapid revenue growth but a loss of $80.7bn (£60.5bn) in the first half of 2026, compared with $13bn a year earlier. Anthropic is reportedly seeking a valuation of $1.5tn to $2tn and could raise as much as $100bn, which at the top end would exceed the $86bn SpaceX raised in June. The company says its technology could cure diseases such as cancer and Alzheimer's, but also warns that AI could destroy jobs and may pose catastrophic or existential risks to humanity.
- Anthropic's IPO filing sheds new light on who stands to make money from public debut
Anthropic's IPO filing outlines financing from its biggest backers ahead of a possible November listing that could rival SpaceX's as the largest IPO in history. Alphabet's agreement could provide up to $20 billion, reduced by up to $10 billion if Google buys nonvoting stock alongside the offering, and carries a 14.99% ownership cap that it can waive; no funds had been drawn as of June 30. Amazon holds about $6.2 billion in convertible notes that could convert into roughly 1.84 billion nonvoting shares under a 12% cap, and it has agreed to provide up to $15 billion more tied to computing milestones. Both companies also benefit from business ties beyond equity: Anthropic generated $16.3 billion in revenue in the first half of 2026, more than all of last year, but spent nearly $9 billion on computing and infrastructure and has committed roughly $450 billion to cloud computing. A PitchBook analyst said Amazon could 'win twice' through compute sales and investment.

- Anthropic IPO reminds this former Amazon board member of Jeff Bezos's AWS bet
Bing Gordon, a Kleiner Perkins partner, Electronic Arts co-founder and former early Amazon board member, compares Anthropic's public listing to Amazon's AWS spending, which required heavy capex with no short-term profit or free cash flow. Anthropic's prospectus shows first-half 2026 revenue of $16.3 billion, up from $1.1 billion a year earlier, alongside an $80.7 billion first-half net loss. Investment bankers are reportedly targeting a listing valuation of around $1.5 trillion to $2 trillion, and Anthropic could debut before the end of November. Gordon recalled Amazon's board approving AWS capex that reached $75 billion in one year, betting on returns three or four years out. He said CEO Dario Amodei must convince investors the spending will be worth it, much like Bezos did with AWS.
- Anthropic's leaked IPO filing raises more questions than answers
Yahoo Finance's Market Hang panel breaks down the reportedly leaked S-1 filing of Anthropic (ANTH.PVT) ahead of a potential IPO, focusing on its revenue, costs and business model. According to the discussion, the company spent $9 billion on compute to generate $16 billion in revenue, 20% of its revenue comes from two customers, and it has $450 billion in compute commitments, about half non-cancelable. Roughly $750 billion more in deals is still under negotiation. Panelists question whether Anthropic can become profitable and generate cash flow, comparing it to WeWork's above-market leases, and say the $2 trillion target valuation mostly reflects market sentiment.
- Anthropic Says It Turned an Adjusted Profit Ahead of Its Expected IPO
Anthropic told potential investors on Wednesday that it reached profitability on an adjusted basis in the third quarter, with third-quarter revenue of $16.8 billion, though it declined to comment on the figures or listing timing. Documents previously reviewed by Bloomberg showed revenue of $386 million in 2024 and about $4.6 billion in 2025, alongside an operating loss above $8 billion and a net loss near $42 billion. Adjusted measures typically exclude stock compensation and noncash items, so they reflect operating trends more than bottom-line results. Google holds roughly 14% of Anthropic under a contract capping the stake at 15%, while Amazon has invested about $8 billion since 2023 and committed up to $20 billion more; the article argues Amazon likely gains more value from a listing, citing its $53.4 billion pre-tax gain in the second quarter and AWS growth. Formal IPO marketing could begin as soon as the week of November 9, with a listing targeted before year-end, though plans may change, and shares of Alphabet and Amazon both fell 1.74% that day.

- Microsoft offers voluntary buyout to 60,000 employees
Microsoft (MSFT) announced on Monday that it is offering voluntary buyouts to roughly 60,000 employees as it reshapes its organization for the AI era. According to reports, the offers cover staff in Canada, India, the United Kingdom and the United States at level 70 and below, including some senior personnel. It follows the company's first voluntary retirement program, announced in May, which offered packages of eight to 39 weeks of base pay depending on position and tenure. The move comes as Microsoft plans to spend $190 billion on capital expenditures in 2026, largely for AI. Its quarterly earnings, with an update on capex and Azure cloud growth, are due Wednesday.
- As Anthropic’s IPO Looms, The Company Faces A Significant Risk From A Surprising Place, Midterm State And Local Elections
Anthropic has publicly filed its Form S-1 for an IPO just days before the midterm elections, and Oxford Economics' chief U.S. economist Michael Pearce says the biggest risk to its AI data center expansion lies with state and local officials. He cites moratoriums, environmental reviews and grid-connection bottlenecks as more immediate threats than Washington. A May Gallup poll found 71% of Americans oppose data center construction near them, and the National League of Cities tracker counts at least 76 localities that have tried halts or bans. Per WSJ via investingLive, Anthropic's compute commitments exceed $600 billion, though TradingKey cites $750 billion, and the S-1 warns that delays in securing energy, water and other critical services could slow new compute.
- Microsoft offers voluntary buyouts to 60,000 employees
Microsoft said Monday it is offering voluntary exit buyouts to certain employees in the U.S., Canada, India and the United Kingdom at experience level 70 or below, with around 60,000 people eligible according to a source. The company is ramping up data center spending to meet strong AI demand while supplying cloud services to Anthropic, OpenAI and others, which has put a strain on its finances. Its first-ever voluntary retirement program, announced in April, was open to around 7% of U.S. employees. Some marketing, sales and engineering teams have chosen not to participate, and employees must decide in December, with those who take the offer leaving on Dec. 31.
- Why PagSeguro Stock Crashed Today
PagSeguro (PAGS) shares fell 26.4% as of 11:20 a.m. ET, after surging earlier this month when conservative candidate Flávio Bolsonaro led incumbent Luiz Inácio Lula da Silva 47.3% to 44.8% in Brazil's first round. Lula won the second round with 51.8% of votes to Bolsonaro's 48.2%, prompting investors to pull back from Brazil-related stocks broadly. Bolsonaro is refusing to concede and challenging the results, alleging the administration suppressed voting in key districts, though it is unclear whether the claims have merit. Several South American heads of state have already congratulated Lula, who will likely remain in office through 2030. The article notes PagSeguro trades at 7.7 times trailing earnings, with analysts expecting more than 10% annual earnings growth over the next five years, which it says makes the stock look cheap regardless of the election outcome.
- Kalshi strikes deal with S&P Dow Jones Indices to expand financial event contracts
S&P Dow Jones Indices has partnered with prediction market platform Kalshi, allowing the exchange to offer event contracts settled on official values of S&P DJI's benchmarks, and making Kalshi a preferred platform for such contracts. The two will also explore building indexes from Kalshi's prediction market data, which could track expectations on economic, political and sporting events, though no timeline was disclosed. The deal follows moves by traditional market operators into prediction markets, including Intercontinental Exchange's commitment of up to $2 billion to Polymarket in October 2025 and Nasdaq's August partnership with Kalshi on market surveillance technology. Separately, S&P Global said it completed its acquisition of blockchain security firm OpenZeppelin, with financial terms undisclosed.
- Bloom Energy Jumps 7% as Post-Earnings Selloff Reverses; FuelCell Rises 6%, Plug Power Edges Higher
Bloom Energy (BE) rose 7% to $207.61 in morning trading, recovering part of last week's post-earnings slide, while FuelCell Energy (FCEL) gained 6% to $11.83 and Plug Power (PLUG) edged up 2% to $1.41. Bloom's third-quarter 2026 results showed revenue more than doubling on demand from hyperscaler and AI data center customers, and the company raised its full-year revenue outlook for the third time this year. However, free cash flow turned negative, ending a run of four positive quarters, and CFO Simon Edwards said the cash use is “not the beginning of a trend,” tying it to inventory, contract assets and receivables built for future deliveries. The next test is whether fourth-quarter 2026 deliveries convert into cash, and Bloom stock is still trading below its pre-earnings level. Meanwhile, the Global X Hydrogen ETF (HYDR) rose 1% and the SPDR S&P 500 ETF Trust (SPY) rose 0.9% to $767.13.
