2026-09-11 — China's last big AI chip startup goes public, and the DOJ takes an interest in NVIDIA

Enflame, the Shanghai chip designer Tencent has funded since 2018, tripled on its first day of trading — the last of China's four big AI-chip startups to reach the public market, and a sign that Chinese investors will pay almost anything for a domestic alternative to NVIDIA. In Washington the mood is the opposite: the Justice Department has opened an antitrust investigation into the $20B licensing deal through which NVIDIA took Groq's chip technology and most of its people without ever calling it an acquisition. Elsewhere, money kept moving into the unglamorous layer beneath the models — inference silicon, optical interconnect, and the power and cooling gear that decides how fast data centres actually get built.

Today in AI

• Enflame's shares opened 188% above their offer price and finished the day up about 206%, valuing the Tencent-backed chip designer near CNY185B (~$26B) after a $912M listing — CNBC link
• The Justice Department is formally investigating whether NVIDIA's ~$20B nonexclusive licence from Groq, which also moved Groq's CEO and COO to NVIDIA, was an acquisition built to avoid merger review — Bloomberg link
• Positron raised $875M at a $5B valuation for an inference chip that bets on huge amounts of ordinary memory rather than raw compute, roughly quadrupling its February mark — Wall Street Journal link
• The Pentagon's Office of Strategic Capital is in talks to lend Fluidstack about $5B, aimed not at a new AI facility but at building US manufacturing for data-centre power and cooling equipment — Reuters link
• DeepSeek released V4.1-Flash, its smallest model yet on a new encoder-decoder architecture, with a 552B-parameter backbone and a one-million-token context window — Reuters link
• Amazon is piloting a US programme letting advertisers buy ChatGPT placements through its own demand-side platform, weeks after OpenAI's ads business passed $1B in annualised revenue — Marketing Dive link
• A Senate disaster-management subcommittee led by Josh Hawley is probing OpenAI's handling of the Hugging Face breach, calling the response "reckless" — Axios link

Marks moved

Groq's role was updated for the DOJ probe; the $3.5B mark is unchanged.

New edges

• tencent —invests_in→ enflame — Tencent remains Enflame's largest shareholder at 17.95% after the IPO, a stake it has held since seeding the company in 2018. SCMP, 2026-09-11. Verified.
• tencent —builds_on→ enflame — Tencent was Enflame's largest end customer in 2025 at 83.79% of revenue, per the listing documents. CNBC/SCMP, 2026-09-11. Verified. Same shape as the existing alibabacloud —builds_on→ cambricon leg: a Chinese cloud running domestic silicon.

Still in talks

• Fluidstack / Pentagon — ~$5B loan from the Office of Strategic Capital under discussion; neither side commented (WSJ via Reuters, 2026-09-10). Debt, so no mark move even if it closes.
• Anthropic IPO — marketing now expected mid-October at the earliest, prospectus public late September, listing just before the midterms; bankers discussing up to ~$2T against the $965B May Series H (Reuters via CNBC, 2026-09-05). Map stays at $965B.
• Moonshot — now exploring dual Hong Kong and Shanghai listings (SCMP, 2026-09-10); carried at the $20B May round until priced.
• Qualcomm / Tenstorrent — no change. The feed item is a recycled June story; the talks were reported at $8–10B on 2026-06-15 and Tenstorrent's CEO denied them on 2026-06-30.
• Unchanged and still open: Thinking Machines, Mercor, Physical Intelligence, Surge, Fal, Nscale's pre-IPO convertibles, and DeepSeek's Shanghai STAR filing.

Leads I could not verify

• Ayar Labs at >$5B rests on search corroboration only. The company's own release discloses no valuation, and the $5B comes from a secondary transaction reported by SiliconANGLE, Converge Digest and Unite.AI — no Reuters, Bloomberg or TechCrunch story carries it. Marked reported; worth a human reading the primary.
• Positron clears the valuation floor at $5B but has no mappable edge — every named investor is a fund with no node here. Secondary write-ups say its Atlas servers use Altera FPGAs and future ASICs go to Intel Foundry; if a primary confirms that, positron —fabricated_by→ intel would admit it.
• Analog Devices / Alif — the deal is solidly sourced, but Alif's only edge runs to ADI, which is not on the map. Adding it means adding a broad analog vendor with no other AI edge: a human call.
• UniPat, reported to have raised $300M backed by Alibaba, appears only in a single low-tier outlet. Not acted on.
• Upstage (AMD-backed, Korea) is said by Bloomberg to be weighing a pre-IPO round — no size, no mark, and Upstage is not on the map.
• Meta/Stilla.ai and Harvey/Guardrails AI are both real but undisclosed-terms acquihires of companies far below the $100M floor — correctly no map change.
• build/logos.py is still blocked by the egress proxy (403 on the favicon host), so enflame joins gimlet, higgsfield and stripe in needing a logo fetched from an unblocked machine.
