132 percent. That is how much ChatGPT's app uninstalls surged year-over-year in April alone, according to Sensor Tower data. The number lands like a verdict on the AI industry's most celebrated growth story—and it raises an uncomfortable question for OpenAI's anticipated IPO: what happens when the growth curve flattens?
The answer, drawn from market intelligence gathered by Sensor Tower, reveals a company in a precarious transition. ChatGPT added monthly active users at 168 percent year-over-year in January. By April, that figure had collapsed to 78 percent. The deceleration is not a blip. It traces a clear arc: explosive adoption giving way to the harder work of retention.
The timing coincides with OpenAI's February deal to provide AI services to the Pentagon. The partnership, which positioned OpenAI as a defense contractor, triggered a 413 percent spike in uninstalls that month—the sharpest single-month surge in the app's history. April's 132 percent uninstall increase suggests the damage to user trust has not fully healed.
OpenAI declined to comment on IPO timing, but the data creates pressure. A company adding users at 78 percent annually still looks like a growth story. One decelerating toward 40 or 50 percent looks like a maturing tech business—and commands a different valuation. With $40 billion in funding secured through recent rounds, OpenAI has runway to wait. But investor patience and public market multiples are not infinite.
The uninstall surge also reflects a structural reality the AI industry has largely avoided confronting: most chatbot users do not form deep habits. They experiment, they drift to rivals offering better features for specific tasks, they simply forget to return. ChatGPT remains substantially larger than any competitor by absolute user base. But dominance in a market where switching costs approach zero is a fragile foundation for an IPO valuation built on growth assumptions.
What OpenAI needs now is not more users. It is fewer leavers. The uninstall data suggests that geopolitical decisions made in San Francisco can ripple into smartphone screens in ways that no investor deck can fully model. The Pentagon partnership may prove commercially sound. It may also have cost OpenAI something harder to quantify: the unconditional enthusiasm of users who believed they were signing up for something transformative rather than something that cleared defense procurement reviews.
The IPO clock is not loud yet. But 132 percent uninstall growth makes a sound that investors cannot afford to ignore.
