Mercor in Talks for $20B Valuation
Mercor, an AI training startup, is reportedly in early-stage talks to raise a funding round at a $20 billion valuation, doubling the $10 billion valuation from its October $350 million Series C. CEO Brendan Foody stated the company's annualized revenue run rate crossed $2 billion, a 100% increase in four months, and Mercor announced the acquisition of Deeptune, with its entire team joining. This comes after a data breach and contractor lawsuits earlier in 2026. Separately, Inspired Capital, the early-stage venture firm founded by Alexa von Tobel and Penny Pritzker, has closed its fourth fund with $450 million in commitments, bringing its total assets under management to nearly $1.4 billion. Despite venture capital concentration in Silicon Valley, Inspired Capital maintains a balanced portfolio, planning about 10 seed-to-Series A investments per year with checks between $1 million and $15 million, reporting 12 unicorns and over 10 exits from its first two funds.

Sierra Raises $950M to Own Enterprise AI
Sierra, the AI startup cofounded by OpenAI chair Bret Taylor and former Google executive Clay Bavor, raised $950 million in a Series E that values the company at $15.8 billion post-money. The round was led by Tiger Global and Google’s GV, with participation from Benchmark, Sequoia, Greenoaks and other existing investors. Sierra sells AI customer-service agents built on foundational models (including OpenAI and Anthropic) and uses a “constellation of models” with proprietary fine-tuned layers. The company reported topping $150 million in ARR in eight quarters and serving more than 40% of the Fortune 50, including customers such as Prudential, Cigna, Blue Cross Blue Shield and Rocket Mortgage. Bret Taylor said Sierra will stay private for now with an IPO “definitely in our future,” and he forecasted a market correction that will leave market leaders intact.
