DeepSeek’s $15.9 Billion Raise Pushes October Venture Funding to $59 Billion

Global venture capital reached $59 billion in October, a 45 percent increase from the same month a year earlier, according to Crunchbase data. The surge was anchored by DeepSeek’s $15.9 billion financing round, the largest venture deal ever recorded for a Chinese company. The influx helped push the month’s total to a new high and underscored the growing dominance of AI-driven businesses in the capital markets.

The United States and China together captured the bulk of the activity, with U.S.-based startups raising $28 billion and Chinese firms securing $20.6 billion. The last time China saw more than $20 billion in a single month was June 2018, when Ant Group closed a $14 billion Series C round. The October figures therefore mark the strongest month for Chinese venture funding in eight years.

Funding was highly concentrated. Seven companies each raised at least $1 billion, together accounting for just over 40 percent of all capital deployed in October. The mega-rounds spanned frontier AI labs, manufacturing, energy, semiconductors, prediction markets and spend-management software. Private-equity firms led much of the money, while multistage venture houses such as Sequoia Capital, Index Ventures and Lux Capital also participated.

DeepSeek’s $15.9 billion raise valued the company at $90 billion, setting a record for private funding of a Chinese tech firm. The deal places DeepSeek among the ten most heavily funded private companies worldwide, makes it the second-most valuable Chinese firm after ByteDance, and ranks it third among private frontier labs behind U.S. rivals Anthropic and OpenAI. In the same month, rival open-source lab Moonshot AI reportedly reached a $50 billion valuation and filed confidentially for a listing on the Hong Kong exchange.

Other notable October rounds included Massachusetts-based Re:Build, which closed a $2.1 billion financing to expand its 2.4 million-square-foot manufacturing footprint. Data-center power and grid builder Axiom raised $2 billion, spend-management platform Ramp secured $1.85 billion and reported annual recurring revenue of $2 billion, and open-source semiconductor company Tenstorrent completed a $1.5 billion Series E after relocating its headquarters to Silicon Valley. Prediction-market operator Kalshi and frontier lab Flapping Airplanes each closed $1 billion Series E and Series A rounds respectively. Additionally, TypeSafe AI announced an $870 million Series A after rapid adoption of its decision model Jev.

AI-focused companies attracted 66 percent of all global capital in October, while semiconductor firms expanded their share of the market. The U.S. IPO market remained subdued as investors awaited Anthropic’s planned November listing, a debut that could eclipse SpaceX’s June offering that raised $85.7 billion. On the merger-acquisition front, at least nine venture-backed firms were bought for more than $1 billion, highlighted by Uber’s $2.3 billion purchase of ezCater.

With two months left in 2026, the venture ecosystem has already set new records for funding, acquisitions and IPO activity. The concentration of capital in a handful of mega-rounds raises questions about how broadly the momentum will spread as the year closes. All eyes now turn to Anthropic’s upcoming IPO, which could redefine the scale of public market exits for AI-centric private companies.
