OpenAI news in 2026 has moved faster than any previous year in the company’s history — driven by explosive revenue growth, a model cadence that released four GPT-5 family iterations in seven months, the controversial Pentagon contract that triggered mass subscription cancellations, and investor interest that would value the company at close to $800 billion. This summary covers the most significant OpenAI news of 2026 through April, with all figures sourced from verified reporting.
The Numbers: OpenAI’s Scale in 2026
- 900 million weekly active users as of March 2026, up from 400 million in February 2025 — 125% year-on-year growth.
- $2 billion per month revenue — equivalent to approximately $25 billion in annualised revenue. OpenAI projects $29.4 billion total revenue for 2026.
- 50 million paying subscribers across all paid tiers. Over 9 million paying business users. 1 million+ enterprise customers as of November 2025.
- $500 billion valuation following the $40 billion Series F funding round in March 2025, led by SoftBank. Total funding raised: $57.9 billion.
- 92% of Fortune 500 companies now use OpenAI products across finance, healthcare, and retail sectors.
- 2.5 billion prompts per day processed across all ChatGPT platforms, with 31% triggering active web searches.
GPT-5.4: The March 2026 Model Launch
OpenAI’s most significant product launch of 2026 was GPT-5.4 in March — a unified model that for the first time combines frontier capability in coding, reasoning, and computer use in a single architecture. Its 75% OSWorld score for computer use surpasses the human expert baseline of 72.4%, making it the first AI model to cross that threshold. The model launched with a 1 million token context window, a new Thinking variant that shows reasoning traces, and a new xhigh effort level on its mini variant.
The launch simultaneously retired earlier model versions: GPT-5, GPT-5.1, and eventually GPT-5.2 from the standard ChatGPT interface, with API access remaining for developers. GPT-5.3 Instant became the new default for all users, with GPT-5.4 Thinking available from Plus plans upward.
The DoD Deal and the #QuitGPT Movement
The most controversial OpenAI news of early 2026 was the company’s contract with the US Department of Defense, signed in February. ChatGPT app uninstalls surged 295% on February 28, 2026, following the announcement, according to TechCrunch. Claude downloads jumped 51% on the same day — reflecting a direct migration from ChatGPT to its main competitor in response to the news. 2.5 million users cancelled or pledged to cancel their subscriptions under the #QuitGPT hashtag.
Anthropic publicly declined the same Pentagon deal, stating that the company “cannot in good conscience” agree to unrestricted military access. This positioned Claude as the safety-first alternative in user perception, contributing to what TechCrunch would later call “Claude Mania” at the HumanX conference in April 2026, where executives described Claude Code as “a religion” among their engineers.
The Go Plan and Advertising
OpenAI’s January 2026 launch of the Go plan at $8/month gave the company a mid-tier between free and Plus, and expanded their monetisation surface. By February, Free and Go tier users in the United States began seeing ads in ChatGPT responses — a significant product shift for a platform built on the premise of clean, uninterrupted AI assistance. The advertising pilot reached $100 million in ARR in under six weeks according to OpenAI.
