CAC 40 opens lower as Anthropic IPO fails to lift Paris stocks

Paris's CAC 40 index opened slightly lower on Tuesday, falling 0.24% to 7,830.43 points, despite positive momentum from US markets the previous day. The index did not benefit from the enthusiasm generated by Anthropic's IPO filing. Orange, the first CAC 40 component to report third-quarter results, raised its 2026 profitability forecast again, now expecting Ebitdaal growth above 4.5% compared to a previous target of over 4%. However, its shares fell slightly as investors worried about potential competition from Elon Musk's SpaceX, which announced plans to acquire low-band spectrum for its Starlink satellites to become a major mobile operator. Anthropic's S-1 filing with the SEC, under the ticker ANT, boosted the Nasdaq and revived interest in artificial intelligence stocks ahead of upcoming earnings from Alphabet and Microsoft. Anthropic reported first-half revenues of $16.3 billion, up 1,300% year-over-year. Saint-Gobain is scheduled to report after the market close.
