The TSX opened lower Wednesday as a global tech selloff weighed on investor sentiment. Markets turned risk-off after a report suggested AI profits may be overstated — or even non-existent — sending shares of Oracle and Penguin Solutions sharply lower.

The Nasdaq also fell, snapping a record streak as Tesla dropped over 4% following the debut of its new sub-$40,000 Model Y and Model 3 vehicles.

  • AI sector selloff deepens – Penguin Solutions (NDAQ:PENG) shares plunged more than 20% after traders dumped the AI infrastructure stock amid uncertainty over profitability in the sector. The decline followed Oracle (NYSE:ORCL), which slid 2.5% after reports that its AI rental business is generating operating losses.
  • Tesla unveils lower-priced EVs – Tesla (NASDAQ:TSLA) shares dropped 4.5% after unveiling new sub-$40,000 versions of its Model Y and Model 3, stoking fears of margin compression in the EV space.
