(Reuters) - Pinterest shares jumped more than 11% on Friday, after a strong quarterly revenue forecast allayed investor jitters about the uncertainty of advertising spending on its platform amid global economic volatility.

A shifting US trade policy coupled with escalating geopolitical tensions have sparked fears of a spike in inflation levels and a possible recession, prompting a broader pullback in consumer and enterprise spending.

However, Pinterest's focus on strengthening the effectiveness of its artificial intelligence tools for creating ad campaigns and a growing Gen Z user base makes it an attractive destination for marketers.

"AI is helping to serve up the right type of ads for different audience segments, which ultimately means there could be a greater propensity to click on the ad if it is relevant," said Dan Coatsworth, investment analyst at AJ Bell.

Pinterest's global monthly active users rose 10% from a year earlier to 570 million in the first quarter, exceeding analysts' expectations according to data compiled by LSEG.

"We believe Pinterest's strategic focus on AI improvements and international expansion is yielding results," said Angelo Zino, senior equity analyst at CFRA Research.

Pinterest flagged a reduction in spending from Asian e-commerce retailers due to the roll-back of the "de minimis" exemption earlier this year, which led notable Chinese advertisers including online marketplace Temu and fast-fashion retailer Shein to slash ad budgets.

Barclays analysts said they expect "trends to worsen in e-commerce advertising" later this year if and when tariffs impact consumer spending.

If gains hold, Pinterest is set to add around $2 billion to its market cap.
