Perplexity's Comet AI browser is now available for iPhones

Perplexity launched its Comet AI browser as a free standalone iPhone app (the prior PC offering cost $200/month) and the browser is also available on Android, Windows and macOS. The iOS build uses Apple's Liquid Glass UI but cannot run third-party extensions; Perplexity admits it collects browser data for ad targeting, raising privacy and scam risks that warrant caution for shopping or transactional use cases.

Analysis

The rise of AI-first browsing experiences shifts value capture away from traditional search-ad mechanics toward first-party commerce funnels and assistant-driven transactions; that reallocation favors firms that own identity resolution, affiliate/checkout plumbing, and post-click measurement rather than legacy display buyers. If an AI browser captures even a few percentage points of mobile browsing time within 12 months, advertisers will reprice bids for that inventory and redirect budgets into partners who can attribute conversions inside the assistant layer.

Regulatory and trust frictions are the main cadence risks. Expect two potential catalysts in the 3–12 month window: (1) product-level trust incidents (misattributed purchases, scam facilitation, hallucinated product claims) that slow adoption rapidly, and (2) pressure from privacy/antitrust enforcers or large platform gatekeepers that reshape allowable data flows — either can materially reverse monetization assumptions.

Second-order beneficiaries include ad-infrastructure and measurement vendors that can ingest new first-party signals (real-time conversion APIs, server-side tracking), and CDN/security providers that mitigate assistant-driven scraping/scams. Conversely, players whose moats are built on cookie-era behavioral graphs will see margin compression unless they pivot to identity and outcomes-based billing. Position sizing should be small and tactical: this is a multi-quarter adoption curve with binary regulatory tails, so harvest asymmetric payoffs via option structures and pairs rather than outright concentrated longs.

Key Decisions for Investors

• Initiate a 6–12 month bearish hedge on Alphabet (GOOGL): buy a 12-month 1x1 put spread (buy 10% OTM put, sell 20% OTM put) sized to 1–2% portfolio. Rationale: protects against a 10–25% re-rating if ad budgets shift to alternative assistant channels; limited premium outlay with defined downside exposure.
• Go long The Trade Desk (TTD) 9–12 month call spread (buy 1x 15% OTM call, sell 1x 30% OTM call) sized to 1–3% portfolio. Rationale: benefits if advertisers migrate to outcome-based buying and need programmatic partners that integrate new first-party signals; asymmetric upside if TTD secures measurement partnerships.
• Pair trade (6–12 months): long Cloudflare (NET) equity vs short Meta Platforms (META) equity, 1:1 dollar exposure. Rationale: NET captures demand for security/CDN and server-side routing as assistant-driven browsing scales; META is more exposed to fragmentation of targeting and may see CPM compression. Keep pair size modest (2–4% net exposure) and monitor privacy enforcement headlines.
• Use small tactical option hedges for consumer tech exposure: buy 9–12 month out-of-the-money puts on ad-revenue-exposed media names (e.g., SNAP or META) sized to 0.5–1% portfolio to insure against sudden ad-share losses following a major assistant adoption or regulation event.
