Feb 11 (Reuters) - Shopify projected quarterly revenue well above market estimates on Wednesday, as the e-commerce platform benefits from resilient consumer spending against ‌a backdrop of U.S. tariffs and rising prices.

U.S.-listed shares of the Ontario, ‌Canada-based company jumped more than 10% premarket after it also announced a new share buyback plan of ​up to $2 billion.

While U.S. President Donald Trump's tariffs, rising cost-of-living challenges, and worries over the labor market have strained shopping budgets, consumer spending has held strong in the U.S., driven primarily by higher-income households.

U.S. consumer sentiment rose to a six-month high ‌in early February, according to ⁠the University of Michigan's Surveys of Consumers. Consumer spending also increased solidly in October and November, aiding healthy holiday quarter sales ⁠for retailers.

That is underpinning growth at Shopify, which primarily generates revenue by taking a cut of merchant sales through payment processing fees and by selling subscription plans to ​merchants.

"We ​ended 2025 with strength across all merchant ​sizes, regions, and channels, setting us ‌up well for 2026," said Shopify finance chief Jeff Hoffmeister.

The company has doubled down on integrating AI-based tools that help sellers with a range of tasks, including analyzing sales data and setting up stores, helping it attract both small-scale entrepreneurs and larger retailers.

Gross merchandise volume, or the total value of goods sold on ‌the platform, was $123.84 billion in the holiday quarter, ​up from $94.46 billion in the prior year.

The ​company expects revenue to rise at ​a low-thirties percentage rate in the January-March quarter, compared with ‌analysts' estimate of a 25.2% rise, ​according to data compiled ​by LSEG.

Total revenue rose 31% to $3.67 billion in the quarter ended December, beating estimates of $3.59 billion.

The company reported a gross profit of $1.69 billion in ​the quarter, a rise of ‌more than 25% from last year. It expects profit to increase ​in the high-twenties percentage range in the current quarter.
