The ChatGPT app has accounted for 47% of global AI app downloads in the second quarter of 2026 so far, SensorTower told Forbes<\/a>, marking a reduction from the 67% of all AI app downloads it accounted for in the same period last year. Anthropic\u2019s Claude makes up 14% of AI app downloads so far in the second quarter of 2026, a dramatic increase from the 1% it accounted for in each quarter last year.<\/p>\n Key Background<\/p>\n Anthropic has raised over $130 billion since it was founded in 2021 by a group of former OpenAI executives including siblings Dario Amodei<\/a> and Daniela Amodei<\/a>, who both have an estimated net worth of $7 billion. Anthropic said its revenue run rate, a metric used to estimate a company’s full-year revenue, crossed $47 billion this month. The company recently struck an agreement with Elon Musk\u2019s SpaceX to use the company\u2019s \u201cColossus\u201d supercomputer<\/a> to \u201cdirectly improve capacity for Claude Pro and Claude Max subscribers.\u201d As it has grown larger, Anthropic has also found itself in the middle of a major government dispute after refusing to give unrestricted access to its AI models, citing concerns over government-sponsored mass surveillance and automated weapon development. The Pentagon later declared Anthropic a national security supply chain risk, a designation the company is fighting in court.<\/p>\n Further Reading<\/p>\n
