Correction (2026-07-29): An earlier version of this piece said Perplexity “closed a $200 million round at a $20 billion valuation” on June 5, 2026, days before Ninth Circuit oral arguments in Amazon v. Perplexity — and framed that as a deliberate, meaningful coincidence. That round is real, but it closed in September 2025, not June 2026, as first reported by TechCrunch and corroborated by The Information via Yahoo Finance (dated September 11, 2025). The “$100 million at $18 billion” round referenced as an April 2026 event also predates this article: it closed in July 2025, led by Accel, per the same TechCrunch report. There was no funding announcement timed to the June 11, 2026 oral arguments that we can verify. The rest of this piece is rewritten to keep only what checks out.
On June 11, 2026, a three-judge Ninth Circuit panel heard oral arguments in Amazon.com Services LLC v. Perplexity AI, Inc. — the first federal appellate test of whether an AI agent acting on a user’s instructions counts as an authorized visitor to a logged-in commercial account. The hearing was in Seattle, and it concerns Comet, Perplexity’s AI browser.
Comet is also the product behind Perplexity’s most recent confirmed valuation jump: $200 million raised at a $20 billion valuation, which TechCrunch reported closed in September 2025 — a step up from the $18 billion valuation Perplexity reached in a $100 million round two months earlier. Both rounds predate this lawsuit’s current appellate stage, but the product they were betting on is the same one now in front of the Ninth Circuit.
What Perplexity Is Actually Betting On
Comet is Perplexity’s AI browser. It launched in July 2025 to subscribers of Perplexity’s $200/month Max plan, then went free worldwide on October 2, 2025, following a three-month waitlist period. Perplexity’s own launch announcement frames Comet as an assistant built into the browser, not a bolt-on chatbot.
What distinguishes Comet from a search-plus-chat product is its Assistant feature: an agent that can, per Perplexity’s and reporters’ descriptions, summarize emails and calendar events, manage tabs, and navigate web pages on a user’s behalf — including logging into accounts like Amazon using the user’s stored credentials to browse, compare, and complete purchases.
Amazon’s lawsuit argues this constitutes unauthorized access under the Computer Fraud and Abuse Act. Judge Maxine M. Chesney of the Northern District of California granted a preliminary injunction on March 9, 2026, barring Perplexity’s agents from accessing Amazon’s systems or creating/using Amazon accounts for that purpose, and ordering destruction of any Amazon data the agents had collected. The Ninth Circuit stayed that injunction pending Perplexity’s appeal. The district court’s position, in short: a user’s instruction to an agent does not extend the user’s own authorization to the agent. Perplexity’s counter-argument, per the same reporting: Comet’s access is the user’s access, “channeled through software,” and the CFAA was not written to reach software acting under explicit user delegation.
The Ninth Circuit’s questions at the June 11 hearing signal which theory the court finds more plausible; a written ruling typically follows weeks to months after argument.
The Valuation Trajectory, Corrected
Perplexity’s confirmed valuation history, per TechCrunch’s September 2025 reporting:
- July 2025: $18 billion, on a $100 million round led by Accel
- September 2025: $20 billion, on a $200 million round (TechCrunch; The Information/Yahoo Finance)
- Total funding at that point: approximately $1.5 billion since founding, per TechCrunch
We could not independently confirm a more recent 2026 valuation figure against primary or named-press reporting strong enough to clear this site’s bar, so we’re not asserting one here.
Investors who priced Comet into a $20 billion valuation were making a forward-looking bet: that the AI-browser surface — where agents act on a user’s behalf — is worth owning, and that the legal theory permitting it holds up. That bet is now specifically being tested in the Ninth Circuit. If Amazon prevails, agents can’t access logged-in sessions on a user’s behalf without affirmative platform-level opt-in, which narrows what an AI browser can do. If Perplexity prevails, user delegation remains the operative legal standard.
Why It’s a Browser, Not an App
Perplexity could have shipped agentic features as an add-on to its main app. It built a standalone browser instead. Browsers are the surface where people research, compare, fill forms, and transact — an agent that wants to act on those tasks needs to be inside the browser doing them, not upstream of them generating a list of recommendations.
Perplexity is not alone in treating the browser as the contested surface:
- Google began rolling out agentic “Auto Browse” features for Gemini in Chrome in late January 2026, letting Chrome take multi-step actions — navigating sites, filling forms, initiating transactions — on a single prompt, per Google’s own announcement.
- OpenAI shut down its standalone Operator browser-agent product in August 2025 and folded its computer-use capabilities into ChatGPT Agent, introduced July 17, 2025, which now handles similar tasks inside the main ChatGPT product rather than as a separate browser.
- Apple has held internal talks about acquiring Perplexity, per Bloomberg’s June 2025 reporting on discussions between M&A chief Adrian Perica and services head Eddy Cue, and separately has more than 2.5 billion active devices worldwide as it rolls out a redesigned Siri.
Whichever company controls the browser surface controls where agent-driven transactions happen — which is the actual stake in the Amazon case: not whether Comet can browse, but whether it can act inside someone else’s logged-in commercial account without that platform’s separate sign-off.
The CEO’s Statement on June 9
Perplexity CEO Aravind Srinivas told CNBC on June 9, 2026 that the company still plans to go public in 2028, regardless of how Anthropic’s and OpenAI’s own IPO plans play out: “Agnostic of these two companies, we were planning for something in 2028 so that still remains the case.”
That statement is real and correctly dated — it’s the one piece of this story that actually happened in the window this article originally claimed. It doesn’t depend on the funding-round timing error above: Srinivas made the comment two days before the Ninth Circuit hearing, in the context of a wave of AI-company IPO filings, not in the context of a fresh funding close.
What Builders Should Take Away
If you’re building a product that users will want agents to access:
The Amazon v. Perplexity outcome will define your technical compliance posture. If the Ninth Circuit upholds the district court’s “user permission doesn’t equal agent authorization” theory, expect to need affirmative, per-agent, per-session consent mechanisms — not just a terms-of-service clause. If Perplexity wins, user delegation remains the operative standard and you may not need separate authorization infrastructure.
If you’re building an agent that acts on behalf of users:
Comet is the clearest example at scale of the design choices — free distribution, logged-in session access, “the agent is the user” legal theory — that are now being tested in court. Whatever the Ninth Circuit signals about “authorized user” is worth tracking closely if your agent relies on the same theory.
If you’re thinking about where AI platform power is accumulating:
The browser is one contested surface, not the only one. Comet, Gemini-in-Chrome, and ChatGPT Agent are three different bets on the same idea — that whoever operates inside the browser session controls the agent-driven transaction.
What’s Coming
A Ninth Circuit ruling typically follows 30–90 days after oral argument. We’ll cover the ruling and what it signals once it lands.
