X Launches AI-Powered Ad Platform Rebuild in Bid to Win Back Advertisers

X, formerly Twitter, has begun a phased rollout of a completely rebuilt advertising platform powered by xAI, describing it as the most ambitious ad system overhaul in the company's 20-year history. TechCrunch reported the rollout started on April 30, with additional features and capabilities planned for the coming months.

What the New Platform Does

According to X, the rebuild replaces its existing ad retrieval and ranking infrastructure from the ground up with AI-driven equivalents. The new system is built around three core pillars:

Simplicity: A redesigned Ads Manager with updated campaign creation tools and a rebuilt interface
Control: Marketers can create and manage targeted campaigns with more direct control over placement and targeting parameters
Performance: AI-driven retrieval and ranking systems that understand user behavior at a deeper level, enabling more precise, relevant, and dynamic ad delivery aligned with real-time content and engagement

Monique Pintarelli, head of global advertising at xAI, said in a statement posted on X: "Very few companies would have the ambition and technical courage to completely rebuild their entire advertising platform in such a short timeframe. This is classic X and xAI — bold, fast, and focused on building something substantially better for advertisers."

The Revenue Context

X's ad business struggled significantly in the years following Elon Musk's takeover of Twitter in 2022, leading the company to shift focus toward other revenue streams including AI and subscriptions. The ad business has been recovering:

X generated an estimated $2.26 billion in ad revenue in 2025, according to eMarketer
That figure is projected to rise to $2.46 billion in 2026
Both figures remain roughly half of Twitter's $4.5 billion ad revenue in 2021, its peak year before the acquisition
The new platform rebuild is the first direct product of X's merger with xAI in March 2025 applied to its advertising business

The Broader AI Advertising Boom

The New York Times reported this week that Google, Meta, and others are enjoying a digital ad boom as AI systems automate ad creation, targeting, and measurement. This has also lowered the barrier for smaller businesses, giving them access to tools previously available only to large advertisers.

What X Has Not Disclosed

No performance benchmarks for the new system have been published
No specific timeline for completing the full rollout has been given
Additional features are planned over the coming months without details on scope or timing
The last major Ads Manager redesign before this one was in 2024, which introduced automated targeting capabilities
