SAN FRANCISCO — Meta Platforms formally launched its ephemeral messaging application 'Instants' to a global audience on Monday, escalating its long-running rivalry with Snapchat just days after the product's limited release drew widespread attention. The app, which causes photos and short videos to disappear after viewing, is integrated with Instagram's existing account infrastructure, giving it immediate access to Meta's more than two billion active Instagram users.

Shares of Snap Inc. fell sharply in pre-market trading on Monday, with several Wall Street analysts issuing revised price targets. Analysts at Morgan Stanley and Jefferies both cited the launch as a material competitive risk, noting that Instants effectively replicates Snapchat's core disappearing-content feature while benefiting from Instagram's entrenched social graph and superior advertiser relationships.

Meta's timing is widely seen as deliberate. The company has long attempted to absorb Snapchat's audience — its 2013 acquisition offer of $3 billion was famously rebuffed — and the launch of Instants follows a period in which Snapchat's user-growth figures have stagnated among the 18-to-24 demographic. Meta's Q1 2026 earnings, reported Sunday, showed AI-driven advertising tools continuing to outperform expectations, giving the company both the financial firepower and strategic confidence to pursue aggressive product expansion.

In a statement, Meta's vice president of product for Instagram said Instants was designed to 'give people a lighter, more spontaneous way to share moments without the permanence that can sometimes make sharing feel high-stakes.' Privacy advocates were cautious, noting that disappearing content does not necessarily mean data is not retained on Meta's servers, a concern already raised by European data protection regulators following the app's soft launch.

Snapchat's parent company had not issued a formal response by mid-morning Monday, though insiders told Reuters the company was preparing a product update announcement of its own, expected later in the week. Analysts noted that Snap's differentiation would increasingly hinge on its augmented reality tools and its Spectacles hardware line — areas where Meta competes but has not yet achieved dominance.
