    "raw_facts": "据媒体报道，美国司法部正在调查英伟达与AI芯片初创公司Groq达成的200亿美元技术授权交易是否经过刻意设计，以规避反垄断审查；交易涉及金额200亿美元，重点审查授权协议是否存在规避实质性并购审查的行为。",
    "transmission_chain": "司法部反垄断调查介入英伟达200亿美元芯片授权交易→或延缓大厂生态扩张并带来反垄断监管合规风险→对半导体与AI算力板块估值情绪形成压制。",
    "invalidation_conditions": "美国司法部正式终止反垄断调查或裁定交易合规，或者交易各方正式披露交易条款并通过反垄断审查。",

    "transmission_chain": "A股半日全市场缩量1170亿至1.09万亿且4300只个股下挫→宏观流动性阶段性收敛压制高估值成长股风险偏好→对半导体ETF午盘走势构成压制。",
    "invalidation_conditions": "午后沪深两市成交额显著放量回升，或半导体与算力硬件板块主力资金重现大幅净流入。",
