The agent could not directly access Kalshi's website due to security blocks (429 errors on all direct fetches) and instead assembled a comprehensive explanation from web search results and third-party sources. It successfully synthesized information about what Kalshi does, its target users, pricing, and competitive positioning, but was unable to verify current offerings, UI details, or site-specific claims firsthand, relying instead on prior knowledge and secondary sources.

• ›All direct fetches of kalshi.com returned 429 security checkpoints, making the site entirely inaccessible to automated agents. The agent pivoted entirely to web search and third-party sources (Built In, CEPR, Dimers, Covers.com, etc.), none of which were hosted on Kalshi's own domain.
• ›Web searches (steps 7–12) returned curated link results pointing to third-party articles and comparison sites; the actual content came from fetching those external sources (step 11 fetched Built In; others were cited from search snippets or prior knowledge). Kalshi's own Help Center and news.kalshi.com appeared in search results but were never successfully fetched.
• ›The agent filled gaps using prior knowledge (60% of sources per metadata) and inference—e.g., assembling the fee structure from multiple secondary sources, inferring user segments from news articles about Kalshi Pro and growth metrics, and constructing a comparison table without direct access to competitor sites.
• ›The final answer is well-structured and factually grounded in what was retrieved (Built In article on mechanics, CNBC on Kalshi Pro, third-party fee breakdowns, competitor comparisons), but the agent explicitly flagged what it could not verify: minimum deposits, state-level restrictions, tax treatment, app UX, support quality, and current market categories.
• ›Kalshi's website is effectively invisible to agents—it publishes no public structured data, llms.txt, or agent-accessible landing page. Discovery and identity happen entirely through third-party intermediaries and search results, not through the company's own properties.
