Global stocks faced a broad sell-off on Wednesday as a confluence of pressures from the artificial intelligence sector, rising oil prices and France's deepening budget crisis spooked investors. The S&P 500 fell 1.21%, the Nasdaq dropped 2.9%, and European and Asian indices also slid, with traders attributing the rout to what Deutsche Bank's Jim Reid called “the wobbles of recent weeks all collided at once.”

The sell-off was led by technology stocks, with AI cloud provider CoreWeave falling 10.06%, now down 22% for the year, and Meta dropping 6.98% in regular trading and a further 0.33% overnight. The weakness came amid reports that OpenAI was pressured by private equity investors to reduce its valuation target in its latest fundraising round from $1.4 trillion to $1.25 trillion, reigniting concerns about frothy AI valuations.

Oil prices added to the gloom, with Brent crude rising to $114 per barrel after the Financial Times reported that President Trump's envoy to the United Nations said the U.S. was prepared to fight Iran for at least another year. Prices later eased back to $113.

Meanwhile, yields on France's 10-year government bond hit 5.1%, a new high, before settling at 5.05%, reflecting persistent investor doubt that the French government can resolve its budget crisis. In contrast, the U.S. 10-year yield fell to 4.9% after a recent peak above 5.3%, suggesting some traders are again treating American Treasuries as a safe haven.

Asian markets were mixed: South Korea's KOSPI rose 0.30%, Japan's Nikkei 225 fell 0.34%, India's Nifty 50 dropped 0.96%, and China's CSI 300 gained 1.71% but remains 15% lower for the year. In Europe, the Stoxx 600 lost 0.36% and the FTSE 100 fell 0.56%. Bitcoin declined to $81,683.

Chris Beauchamp, chief market analyst at IG, urged perspective. “It has been a horrible month for tech stocks, but the Nasdaq 100 was at a record high just a few weeks ago … the index is up 20% from a year ago and nearly 30% from March,” he said. “Those screaming that the bubble is popping need to put these moves in context … This is digestion, not a crash.”

Nasdaq futures were up 0.28% before the New York open, while S&P 500 futures were flat, suggesting some traders are buying the dip.

Analysis

Why This Matters

  • The simultaneous sell-off in AI stocks, oil-sensitive sectors and French bonds signals that multiple macro risks are now compounding, raising the stakes for global portfolios.
  • A sustained decline in tech could spill into broader market sentiment, especially if AI funding rounds continue to face valuation pushback.
  • Rising oil prices and French bond yields add inflationary and sovereign debt concerns, potentially influencing central bank policy decisions.

Background

Financial markets have been volatile in recent weeks as investors juggle conflicting signals: a strong U.S. economy, elevated interest rates, geopolitical tensions in the Middle East, and fiscal strains in Europe. France, in particular, has seen its borrowing costs climb as the government struggles to pass a budget that meets EU deficit rules, while the AI sector, a key driver of the 2024-2025 rally, faces growing scrutiny over valuation sustainability.

Key Perspectives

Equity bulls (like IG's Chris Beauchamp): The pullback is a normal correction after extraordinary gains. The Nasdaq 100 remains up 20% year-over-year, and the Nikkei 225 is up 35% from last March. This is "digestion, not a crash."

Fixed-income and commodity traders: The rise in French yields to 5.1% and oil to $114 reflect real, unresolved risks, a French fiscal crisis and a prolonged U.S.-Iran confrontation, that could persist and deepen.

AI investors and skeptics: The OpenAI valuation cut is a bellwether. If private equity is demanding lower prices, public AI stocks might face further pressure as the hype cycle matures.

What to Watch

  • Whether Nasdaq futures hold their early morning gains or reverse, a key test of dip-buying conviction.
  • French 10-year yields: if they break above 5.1% and stay there, it could trigger broader European contagion.
  • Oil price trajectory: a sustained move above $115 would add to inflation fears and hurt consumer discretionary stocks.
  • AI fundraising news: any further valuation reductions from major AI companies could accelerate the tech sell-off.
