Wangsu values Sand.ai near $1B with 300M yuan bet

China’s Wangsu Science and Technology approved a 300 million yuan investment for 4.4% of Sand.ai, implying a roughly $1.01 billion valuation for the video-generation company, according to the exchange filing. Sand.ai reported 17.4 million yuan of first-half revenue and a 151.6 million yuan loss, so the headline is a strategic option on edge video inference, not operating proof; the filing analysis lays out the gap. Builders should file this under distribution and balance-sheet bets, alongside the archive’s China model-race analysis, rather than treat valuation as evidence of product demand.
