Merger split ad and AI revenues
xAI
The merger changed xAI from an AI lab with early product revenue into a company where most near term scale came from owning a large consumer internet asset. By the end of 2025, the combined business was being measured on two very different engines, X advertising and subscriptions on one side, and xAI model, API, and Grok revenue on the other. That is why a late 2025 consolidated quarterly revenue figure can sit far below a year end annualized number for the full combined entity.1 2 3 4
- Before the merger, xAI was still small on a revenue basis. It exited 2024 at about $100M annualized revenue, largely from Grok tied to X Premium and early API usage. After the March 2025 deal, reported revenue started to include X, which made the denominator much bigger overnight.1 3
- The Bloomberg reviewed Q3 2025 figure of $107M appears to describe xAI's AI revenue line inside the post merger company, not the full economic output of the combined business. Separately, X's business was still material, with X subscriptions alone later reaching a $1B annualized run rate, and X revenue estimated around $2.7B in 2025.2 3 4 5
- That mix matters because investors were funding two different things at once. The legacy X asset supplied users, distribution, and subscription cash flow, while xAI was consuming enormous capital to build compute, with $7.8B of cash spent in the first nine months of 2025. The merger let one story mask the immaturity of the other.2 3 5
Going forward, the key question is how fast xAI can shift the combined company from being supported mainly by social media revenue into being driven mainly by AI revenue. If Grok, API sales, and enterprise products overtake ads and subscriptions, the merger will look like a distribution shortcut. If not, X remains the cash and audience base underwriting a very expensive model buildout.2 3 4 5
