Altman's Governance Scrutiny Accelerates Anthropic's IPO Race

The House Finance Committee hearings expose dual-class voting risks as Anthropic seizes the moment to go public first.

Sam Altman appeared before the House Financial Services Committee on Tuesday, fielding questions about OpenAI's governance structure, capitalization table, and the adequacy of disclosures related to its reported $300 billion valuation. The hearing was convened after a group of Republican senators sent a letter to the SEC questioning whether OpenAI's dual-class stock structure — which gives Altman supervoting control — meets the exchange's listing standards for governance accountability.

"When one individual holds 51% of voting power in a company valued at $300 billion, we need to understand who that individual answers to," said Representative Patrick McHenry, opening the hearing. Progressive Democrats joined Republicans in expressing concern that OpenAI's governance model could set a precedent for other AI companies seeking public capital. Altman's prepared testimony emphasized OpenAI's transition to a public benefit corporation and its commitment to AI safety benchmarks. He also disclosed new details about the company's capitalization: Microsoft holds a 49% stake, venture investors hold 23%, and employees hold the remainder through options and RSUs. Altman himself holds no direct equity but controls the voting stock through a holding entity.

The market reaction was muted. OpenAI has not yet publicly filed its S-1, and the scrutiny is largely procedural. But the hearing signals that AI companies seeking public capital in 2026 will face governance scrutiny not seen in decades. The question is no longer whether AI companies can go public. It is whether their governance structures can survive the process.

Anthropic picks Goldman and Morgan Stanley for October IPO

Anthropic announced on Wednesday that it has selected Goldman Sachs and Morgan Stanley as lead underwriters for a public offering targeted for October. The announcement comes less than 48 hours after OpenAI's congressional hearing. Anthropic CEO Dario Amodei told CNBC that the company "is not looking to replicate OpenAI's governance mistakes." Anthropic's board includes independent directors and a 10x voting cap on founder shares — a direct contrast to OpenAI's supervoting structure. The company's last private valuation was $61.5 billion.

The timing is aggressive. Anthropic has yet to report a full year of audited financials, and its revenue remains heavily dependent on a handful of enterprise customers. Anthropic is essentially betting that reaching public markets before OpenAI is more important than perfecting the balance sheet. If the offering succeeds, it becomes the first major AI lab with public equity. If it struggles, it could chill the broader AI IPO pipeline.

Google AI Mode launches in EU, triggers investigation

Google announced Wednesday that AI Mode — the agentic search interface unveiled at I/O — is now available in the European Union, United Kingdom, and Japan. The EU launch triggered an immediate regulatory response. The European Commission's Directorate-General for Competition confirmed a "preliminary investigation" into whether AI Mode constitutes an abuse of Google's dominant search position by self-preferencing its own AI-generated content over third-party publishers.

French publishers' association Geste filed a formal complaint arguing that AI Mode's summarization effectively replaces visits to publisher websites, starving them of advertising revenue. Google's defense, outlined in a blog post, is that AI Mode cites sources and includes links. Publisher associations counter that click-through rates from AI summary citations are "materially lower" than standard search results. The outcome will likely set the regulatory framework for how AI interfaces can ingest and republish third-party content across all platforms.

Open-Source Pulse

DeepSeek reported that its V4 preview — released Monday — attracted over 10 million users in its first day. The model uses a mixture-of-experts (MoE) architecture with 1.2 trillion total parameters but only 32 billion active per forward pass. The design keeps inference costs extremely low. DeepSeek is reportedly charging $0.08 per million tokens for API access — roughly one-third of GPT-4.5 pricing and one-fifth of Gemini 3.5's. The company told The Verge that it is "selling compute at cost" to gain market share.

The risk is sustainability. DeepSeek's burn rate on inference is likely massive at $0.08 pricing. But the user numbers validate a market thesis: developers are price-sensitive and will switch models for a 5x cost advantage, even if the capability gap is modest. The open question for the open-source ecosystem is whether DeepSeek's pricing forces Western labs to match or subsidize their own APIs.

Builder's Corner

AMD's Q1 2026 earnings confirmed what Epoch AI flagged for NVIDIA: high-bandwidth memory is eating the chip. AMD's data center unit reported $4.8 billion in revenue, up 34% year-over-year, but gross margins contracted 180 basis points to 47%. CFO Jean Hu attributed the compression directly to "HBM pricing dynamics," noting that memory costs rose 22% quarter-over-quarter while logic die costs were flat.

"We are not NVIDIA," Hu told analysts. "We do not have the pricing power to pass component inflation through to customers who have alternatives." The comment matters for builders. NVIDIA's 74.9% gross margins and hyperscaler lock-in allow it to absorb HBM inflation. AMD, Intel, and custom silicon efforts at Google and Amazon do not have the same cushion. The AI chip business is bifurcating into a NVIDIA tier and everyone else. For engineers selecting hardware, the implication is that second-tier chip costs will continue to rise faster than performance.

The View

The week's central tension is between governance scrutiny and growth urgency. OpenAI's congressional hearing and Anthropic's IPO acceleration are two sides of the same coin: both companies need public capital, but they are approaching the threshold from opposite directions. OpenAI has the revenue and the brand but carries governance baggage that regulators are now unpacking. Anthropic has the cleaner structure but lacks the scale and audited history that public-market investors typically demand. The risk for both is that the window for AI IPOs is narrower than the hype suggests. If Anthropic's offering struggles, it does not just hurt Anthropic. It reprices the entire AI equity pipeline. And if OpenAI's governance questions deepen, it could delay the largest pure-play AI IPO in history. The HBM cost squeeze adds a second layer: even if demand stays parabolic, an increasing share of chip spending flows to memory fabs, not to logic designers. The buildout continues. The profits may not.

The Miss

A Bloomberg story published Tuesday reported that several Fortune 500 companies are quietly building "shadow AI" budgets — unaudited lines of credit allocated to AI experiments that do not appear on official IT budgets. The practice is spreading because CIOs cannot get board approval for AI spending without proof of ROI, but cannot get proof of ROI without running experiments. The result is a growing black market in corporate AI spending that is invisible to investors, auditors, and regulators. The article was buried under earnings coverage. It deserves more attention.
