Wall Street digests record fundraising haul as AI race intensifies

Nearly $300 billion flooded into AI ventures in Q1 2026, representing 81% of global venture activity, as OpenAI raised $122 billion and Anthropic closed a $65 billion Series H round at a $965 billion valuation, surpassing OpenAI. Alphabet also announced an $80 billion capital raise, fueling record highs in US equity indices.

Wall Street digests record fundraising haul as AI race intensifies Nearly $300 billion flooded into AI ventures in a single quarter, reshaping how capital markets think about technology investment. The AI sector just inhaled roughly $297 billion in a single quarter. To put that in perspective, that figure represented 81% of all global venture activity in Q1 2026. The remaining 19% was left for everything else: biotech, fintech, climate tech, and whatever else dared to compete for investor attention. OpenAI set the pace with a staggering $122 billion fundraising round in Q1. That single raise would have been considered science fiction two years ago. Anthropic wasn’t far behind in ambition, closing a $65 billion Series H round on May 28 at a post-money valuation of $965 billion. That figure surpasses OpenAI’s own valuation of approximately $852 billion from earlier in the year, making Anthropic the most valuable private AI company on the planet, at least for now. xAI, Elon Musk’s AI venture, pulled in $20 billion during the same period. Following its merger with SpaceX, the combined entity is reportedly targeting an IPO that could reach up to $75 billion as of early June. Alphabet, on June 1, announced plans to raise $80 billion through public stock sales. That package includes a $30 billion public offering and a $10 billion private placement with Berkshire Hathaway. US equity indices, including the S&P 500 and Nasdaq, approached record highs in early June, propelled in large part by investor enthusiasm for AI hyperscalers. Anthropic’s leap past OpenAI in valuation is particularly telling. Just months after OpenAI commanded the highest private valuation in tech, a competitor overtook it. The gap between current revenue and current valuations, particularly at the $852 billion to $965 billion range, leaves very little room for execution missteps.
