How many people use ChatGPT instead of Google in 2026?

By September 2025 OpenAI claims ~800 million weekly users of ChatGPT (Reuters). Google still leads by far with ~9 billion queries per day. But the trajectory is clear: Gartner expects 30-50% of searches to flow through AI answer engines by 2028. The shift is underway, not complete.

How many people use ChatGPT instead of Google in 2026, for AI engines?

Here's the simplest comparison. ChatGPT counts 800M+ weekly users in 2025 (Reuters, OpenAI press); Perplexity ~22M monthly actives disclosed late 2024; Gemini is harder to quantify, embedded inside Google. On the other side, Google still runs ~9 billion queries per DAY (Statista, Internet Live Stats). Volume gap is huge.

Three takeaways. "The first takeaway is that trajectory beats stock: ChatGPT went from zero to 800 million weekly users in under three years, while Google needed twenty," argues Lorenzo Eeman, founder of PROEMA. Second, usage frequency rises: power users ask 20-50 questions a day to an LLM versus 3-4 Google searches (SparkToro). Third, query qualification shifts, LLM questions are longer, more contextual, closer to actual buying intent.

Practical rule: don't think « replacement », think « gradual cannibalisation ». For your decision-maker personas (CMOs, CEOs, founders) LLM use is already majority on certain categories (B2B supplier search, copywriting). For consumers it's still minority but grows 30-40% a year. Two years of anticipation is good strategic hygiene.

What the 2026 numbers say on How many people use ChatGPT instead of Google in 2026

Public benchmarks converge on three signals. ChatGPT hit 900 million weekly active users in early 2026 (OpenAI announcement reported by TechCrunch on February 27, 2026). Google AI Overviews reached 47 % of European queries in March 2026 (Semrush Sensor 2026). Perplexity reported +800 % year-over-year query growth. In practical terms: informational traffic leaving Google's blue links for answer engines is no longer marginal, for a B2C F&B site, it typically runs 15-25 % of measurable traffic via Cloudflare AI Crawl Control or GA4 « ai-referrer » segments.

Why How many people use ChatGPT instead of Google in 2026 isn't optional for serious brands

The 5W Citation Source Audit Q1 2026 shows LLMs concentrate citations on a tiny set of sources: Wikipedia (13.15 % at ChatGPT) + Reddit (11.97 %) = 25 % of citations, followed by vertical databases (Yelp, TripAdvisor, IMDB depending on context). For F&B brands, the problem is binary: either you're in the sources LLMs read, or you never show up, there is no « page 2 » of LLM citation. PROEMA's documented discipline targets exactly this presence: structure content via Schema.org, publish on hubs crawlers actually read, and lock down Author/Person + sameAs Wikidata to clear the confidence filter.

Translation: stop watching from the bench. By June 2026, a B2C F&B brand with no Schema.org Author/Person, no sameAs Wikidata, and no FAQPage gets approximately zero LLM citations on long-tail informational queries, confirmed across PROEMA verticals (expertvin.be, expertcafe.be, zeroproof.one). The fix isn't theoretical: it's three concrete deliverables (Schema markup audit + Wikidata entry + FAQ playbook 5-blocs structure) executed in six to eight weeks.
