Bursa Malaysia’s key index continued its downward trajectory to close lower at midday, aligning with a wider regional retreat in technology equities.

The sell-off was driven by market reaction to reports that US chipmaker Nvidia is in discussions with OpenAI to help fund a US$250 billion financial backstop.

The news has prompted investors across Asia to reassess exposure to high-valuation tech names, with Kuala Lumpur’s market reflecting the broader sentiment shift.

The decline in Kuala Lumpur follows a period of profit-taking that has weighed on the market in recent sessions.

Traders had previously booked gains after a sustained upward trend, but the fresh catalyst from the US tech sector has accelerated the pullback.

The midday close underscores how quickly sentiment can shift when major players in the AI supply chain announce significant capital arrangements, even if those deals remain in the discussion phase.
