TSX futures climbed 0.5% on Wednesday as investors focused on Nvidia's upcoming earnings, seen as a critical indicator for the AI sector and broader markets. The S&P/TSX 60 index standard futures rose 8 points, following Tuesday's 0.6% gain in the composite index that hit an all-time high. While the materials sector gained 1.8% on rising gold and copper prices, Bank of Nova Scotia slipped despite strong results. U.S. futures also edged higher, buoyed by Meta's AMD deal and Anthropic partnerships, though concerns about AI disruption remain.

Nvidia's results, expected after the close, will test market confidence; analysts forecast a 62% profit jump and 68% revenue increase. The chip maker's performance is viewed as a bellwether for AI demand and global stock direction, with investors nervous about its impact. Salesforce and Snowflake earnings also loom after the close.
