Switch initiates $2B funding round led by Andreessen Horowitz

Switch is kicking off a private funding round targeting roughly $2 billion, with Andreessen Horowitz leading the charge. The round, first reported by Bloomberg, would place Switch among a small but growing club of startups commanding ten-figure capital raises in a single shot.

The details are straightforward: Switch is raising approximately $2 billion in private funding, and Andreessen Horowitz is the lead investor. Beyond that, the specifics of the company’s product, valuation, and other participating investors remain to be seen.

This round fits neatly into a pattern that has defined a16z’s recent strategy. The firm co-led a $2 billion round for Cursor, the AI coding startup built by Anysphere, alongside Nvidia and Thrive Capital. That deal pushed Cursor’s valuation above $50 billion, making it one of the most richly valued private companies in the world.

Then there was Thinking Machines Lab, which closed a record $2 billion seed round, also led by Andreessen Horowitz. The Switch round would mark at least the third time in recent memory that a16z has anchored a raise in the $2 billion range.
