The FTSE 100 is poised for a sharp fall to end the week, with futures pointing to an **86-point slide** as global markets resume the sell-off seen earlier in the week.

The projected decline would erase Thursday’s modest **20.2-point gain**, which saw the index close at **9,527.65**, after a chaotic night on Wall Street where early optimism abruptly gave way to heavy losses.

Wall Street’s main indices ended Thursday sharply lower, marking the collapse of an initial Nvidia-fuelled rally. The **S&P 500 fell 1.5%**, the **tech-heavy Nasdaq dropped 2.2%** and the **Dow Jones lost 0.8%**, as fears of an overinflated AI boom resurfaced.

Earlier in the session, Nvidia’s market-beating results had temporarily calmed concerns over a speculative AI bubble, helping its shares jump nearly **5%** and lifting both the Nasdaq and S&P 500 — but the optimism proved short-lived as selling pressure quickly returned.

“It was by far the wildest session on Wall Street since the post-Liberation Day sell-off that almost caused a meltdown in global markets,” said Kyle Rodda, market analyst at Capital.com.

Rodda suggested the sharp reversal was likely driven by **monetary policy uncertainty**, noting that while the jobs report lifted expectations of a December Fed rate cut, the odds still remain against one.

The nervous tone has spread across Asia. Markets there are firmly in negative territory this morning, with the **Nikkei, Hang Seng and Shanghai Composite all down more than 2%**.

**Bitcoin slides to April lows as October slump deepens**

Bitcoin fell sharply throughout the day, sliding to levels last seen in April as the sell-off that began in October gathered pace.

The world’s largest cryptocurrency dropped **5.5pc to around £66,000**, extending a persistent downturn that has steadily eroded confidence and wiped out recent gains.
