Global markets staged a powerful rebound on July 21, 2026, with Asia-Pacific equities leading the recovery after weeks of AI-driven selloffs. The turnaround comes as investors weigh the disruptive impact of China's Kimi K3 large language model against upcoming earnings from U.S. tech giants, with European and U.S. markets poised to follow Asian momentum higher.
Asia-Pacific Leads Global Tech Rebound
Japan and South Korea kicked off the rally with strong gains across semiconductor and tech names. Japan's Nikkei 225 closed 3.26% higher at 66,232 points, with memory chipmaker Kioxia surging 14% and SoftBank climbing 6.1%. South Korea's KOSPI index rose 3.56%, at one point jumping more than 4% to trigger the exchange's Sidecar circuit breaker that halts programmatic buying. Samsung Electronics rallied 6.1% and SK Hynix gained 4%, driven by data showing South Korean semiconductor exports surged 180.6% year-over-year in the first 20 days of July. China's tech markets delivered the most dramatic performance. The STAR 50 Index — China's benchmark for semiconductor and AI stocks — soared 10.73% in an epic intraday reversal, having been down 3% in morning trade. The session marked the index's biggest single-day gain of 2026, with 2.96 trillion yuan in total market turnover. Chip equipment and AI design stocks led the charge, with dozens of names hitting their 20% daily upside limit.
Kimi K3 Disruption Continues to Reshape AI Valuations
The aftershocks from Moonshot AI's Kimi K3 launch continue to reverberate through global AI equity markets. Dubbed the "DeepSeek 2.0 moment" by JPMorgan, the 2.8-trillion-parameter open-source model has topped global coding benchmarks and undercuts flagship models from OpenAI and Anthropic by 3–5x on pricing. With full open-source weights scheduled for release on July 27, the model threatens to commoditize frontier AI capabilities that U.S. players have long priced at a premium. The shock wiped roughly $470 billion from U.S. AI stocks in three trading days last week, but this week's bounce suggests markets are beginning to differentiate between winners and losers. Chinese AI infrastructure plays have rallied sharply on expectations of surging domestic demand, while U.S. cloud and chip stocks are attempting to form a near-term bottom.
U.S. and Europe Poised to Follow as Earnings Season Looms
U.S. stock futures point to a higher open, with Nasdaq 100 contracts up roughly 1% in Asian trading hours. European markets are also expected to open firmly higher, tracking the Asian risk-on mood and easing oil prices that have cooled immediate inflation fears. All eyes now turn to the upcoming Magnificent Seven earnings season, which kicks off this week with Tesla, Alphabet, and Intel. The single most critical metric for markets will be capital expenditure guidance — investors are waiting to see whether hyperscalers maintain their aggressive AI infrastructure spending plans or dial back amid pricing pressure from new Chinese entrants. Until those capex numbers land, this relief rally remains on fragile ground.
