Search & fact check with cited sources for What happened with Zhipu AI (Z.ai/Knowledge Atlas Technology) this week regarding the launch of its ZCode coding agent built on GLM 5.2, the stock's 16.6% plunge amid a global semiconductor selloff triggered by Meta's cloud capacity plan

Key product specs:

• Architecture: 744B total parameters, ~40B active (MoE)
• Context window: 1M tokens (usable, not just claimed)
• License: MIT open weights (no regional restriction)
• Performance: Trails Claude Opus 4.8 by roughly 1% on long-horizon benchmarks

2. Stock's 16.6% Plunge & Global Semiconductor Selloff

The 16.6% figure does not appear as a single-day event in available sources this week. However, multiple significant drops are documented:

• June 23, 2026: Zhipu plunged 15.2% — the steepest single-day decline since its listing — during a broad Hong Kong AI stock selloff . Reports also note an intraday drop as wide as 25% before paring losses, opening down ~14% at HK$2,060 per share .
• Late June 2026: Zhipu and MiniMax lost more than 40% of their market value over two weeks as investors reassessed Chinese LLM valuations. By June 12, Zhipu shares had fallen to HK$1,097, down 44.9% from their peak .
• July 1–2, 2026 (this week): A new wave hit. On July 1, news that Meta is entering the AI cloud infrastructure business (to sell off excess data center capacity) triggered a global semiconductor rout . Memory chipmakers Micron, SanDisk, and others dropped ~10.6% on July 1-2 . The Philadelphia Semiconductor Index fell as much as 6% in two days — its worst start to a quarter in months . Axios notes the catalyst was Meta's cloud plan, which raised oversupply fears .

Direct Zhipu impact this week: Specific 16.6% figure not confirmed in the evidence. The broader context is that Zhipu was already in a steep correction from its peak when the fresh Meta-led semiconductor selloff added further pressure on AI-exposed Hong Kong names.

3. Financial & Market Performance Since January 2026 Hong Kong Listing

IPO & initial run

The meteoric rise and sharp correction

• By February 13: Stock had soared 320% from IPO price, and Zhipu hired banks for a second listing in Shanghai .
• By June 2: Chairman Liu Debing amassed a $22.4 billion fortune as the stock surged ~1,000% year-to-date .
• Peak market cap: One source cited a peak of ~HK$1.07 trillion (about $137B) around mid-June .
• By June 12: Shares crashed to HK$1,097, down 44.9% from peak .
• By June 23: Caproasia (LinkedIn) still reported +1,717% YTD from IPO price, with a ~$119 billion market value .
• Current status: The stock remains well above its IPO price but deeply corrected from its June peak, and now faces additional headwinds from the global chip/Meta selloff this week.

Financial fundamentals

• FY2025 revenue: RMB 724.3 million (approx. $100M), up 132% year-on-year .
• H1 losses (2025, implied): In the first half of 2025, R&D costs escalated 86% to $228 million — over eight times revenue at that point .
• FY2024 net loss: ¥2.96 billion (approx. $410M), up from prior year .
• Profitability: Still deeply unprofitable. Reuters noted Zhipu is on a "treacherous path to profit," spending heavily on model training while revenue remains small relative to costs . The company hiked AI model access prices twice in 2026 as a monetization push .

Summary

This week Zhipu advanced its product side with a new GLM-5.2 agent tool aimed at competing with Anthropic's Claude Code , while facing continued market pressure from a broader AI/tech valuation correction and the fresh Meta-cloud-triggered semiconductor rout. The stock remains up dramatically from its January IPO but has fallen 40–50% from its mid-June peak. Financially, Zhipu is growing revenue rapidly (~132% YoY) but burning heavily on R&D with no near-term profit in sight .
