Anthropic Could Be the Next Mega IPO: 2 Magnificent Stocks That Already Own a Piece of the AI Unicorn

Anthropic, the maker of the Claude AI models, filed a confidential draft S-1 and is rumored to price its IPO as early as next month. Amazon has an early $8B + $5B investment (with up to $20B more tied to milestones), while Alphabet committed up to $40B (with $10B upfront plus $30B contingent), giving AMZN/GOOGL shareholders pre-IPO exposure. The article also cites strong AI-driven cloud momentum—Alphabet Q2 net income of $112.1B (with $98B “other income” largely unrealized gains from equity investments) and Amazon Q2 $53.4B in non-operating pre-tax other income primarily from Anthropic investments—supporting a bullish read-through on returns from Anthropic’s stake.

Analysis

The market is likely overweighting the mark-to-market upside and underweighting the operating signal. A public valuation for a frontier-model vendor would mainly matter because it validates that large cloud commitments can be converted into durable workload share; that is a better read-through for AMZN and GOOGL than for the IPO itself. The first-order P&L uplift from equity stakes is noisy and mostly non-recurring, but the second-order effect is that AWS/GCP become more credible “default rails” for enterprise AI spend, which can support a longer duration multiple if cloud growth reaccelerates into the next 2-3 quarters.

The more interesting competitive effect is on Microsoft: if the market starts to view Anthropic as less captive and more multi-cloud, Azure’s AI exclusivity narrative weakens at the margin. That does not mean MSFT loses share immediately, but it raises the bar for proof that AI monetization is translating into net-new workloads rather than internal cannibalization. For NVDA, the signal is only indirect; any incremental training/inference demand is likely already embedded in the broader AI capex trade, so this headline is more about where the workloads land than about chip demand itself.

The contrarian view is that the IPO could be a “sell the markup” event: public price discovery may be lower than the private round chatter, and the market may discover that the valuation step-up is less relevant than milestone-based funding terms and customer concentration. The real falsifier for the bullish cloud thesis is not the IPO price but whether AWS/GCP report sustained acceleration; if cloud growth stalls over the next 1-2 quarters, the equity-stake narrative fades quickly.

Key Decisions for Investors

• Long AMZN into the IPO window, but only on pullbacks of 3-5%; thesis is cloud-workload share, not the mark-up on Anthropic. Falsify if AWS growth reverts toward low-20s or management frames AI spend as margin-dilutive.
• Long GOOGL vs. MSFT as a 1-3 month pair trade: the setup favors the cloud platform with the cleaner embedded optionality and less dependence on one AI partner. Exit if Azure AI revenue inflects faster than GCP for a quarter.
• Avoid chasing NVDA on this headline; use it instead as a hedge against an overheated AI-capex basket. The upside linkage is weaker than the market may assume unless Anthropic materially expands inference spend.
• If AMZN/GOOGL gap up on IPO pricing, sell part of the strength and wait for post-event digestion. The bookable gain from equity stakes is likely more of a sentiment catalyst than a durable earnings driver.
