While tech giants could technically replicate Perplexity, their core business models—advertising for Google, e-commerce for Amazon—create a fundamental conflict of interest. An independent player can align purely with the user's best interests, creating a strategic opening that incumbents are structurally unable to fill without cannibalizing their primary revenue streams.

Unlike OpenAI or Google, Perplexity AI doesn't build its own foundational models. This lack of a core asset means it cannot offer publishers lucrative licensing deals for their content. Consequently, mounting copyright lawsuits from major publishers pose a much greater existential threat, as Perplexity has no bargaining chips.

In AI M&A, recency is key. Companies pre-ChatGPT often had to rewrite their entire stack and relearn skills, making their experience less relevant. Acquiring a company with post-ChatGPT experience ensures their tech and knowledge are current, not already obsolete.

Google could surpass ChatGPT in usage overnight by replacing its traditional search interface with Gemini. However, its reluctance to do so stems from a fear of cannibalizing its core, highly profitable search ad business, creating an opening for competitors despite its superior distribution.

While ChatGPT is still the leader with 600-700 million monthly active users, Google's Gemini has quickly scaled to 400 million. This rapid adoption signals that the AI landscape is not a monopoly and that user preference is diversifying quickly between major platforms.

By integrating Google's Gemini directly into Siri, Apple poses a significant threat to OpenAI. The move isn't primarily to sell more iPhones, but to commoditize the AI layer and siphon off daily queries from the ChatGPT app. This default, native integration could erode OpenAI's mobile user base without Apple needing to build its own model.

Apple is avoiding massive capital expenditure on building its own LLMs. By partnering with a leader like Google for the underlying tech (e.g., Gemini for Siri), Apple can focus on its core strength: productizing and integrating technology into a superior user experience, which may be the more profitable long-term play.

Perplexity is pursuing multiple, seemingly unrelated strategic directions at once—competing with browsers, financial terminals, and trying to acquire social media assets. This scattered approach suggests a lack of focus that could undermine its long-term viability.

Similar to how mobile gave rise to the App Store, AI platforms like OpenAI and Perplexity will create their own ecosystems for discovering and using services. The next wave of winning startups will be those built to distribute through these new agent-based channels, while incumbents may be slow to adapt.
