NIO Stock Jumps Overnight: Onvo's Breakout And ES9's Hot Start Fuel Record 2026 Deliveries

• Nio's May deliveries reached 37,705 vehicles, up 62.3% year-over-year and 28.4% from April.
• Onvo was the biggest growth driver, delivering 12,029 vehicles in May, up more than 91% from a year ago.
• The new Onvo L80 SUV delivered 5,949 units within 15 days of launch, helping the brand surpass 10,000 monthly deliveries.

U.S.-listed shares of Nio, Inc. (NIO) jumped over 2% in overnight trading heading into Monday after the Chinese EV maker posted its strongest delivery month of 2026, with surging demand for Onvo's new SUVs and early signs that its flagship ES9 launch may be resonating with premium buyers.

Nio’s U.S.-listed shares snapped three straight sessions of gains in May to end the month over 12% lower. 

Onvo Fuels May Delivery Surge

The company delivered 37,705 vehicles in May, up 62.3% from a year earlier and 28.4% from April, marking its highest monthly delivery total so far this year. Total deliveries for the first five months of 2026 reached 150,526 vehicles, representing year-over-year growth of nearly 69%.

A key contributor to May's performance was Onvo, Nio's mass-market sub-brand, which delivered 12,029 vehicles during the month. Deliveries more than doubled from April and rose over 91% from a year ago. The growth was largely driven by the Onvo L80, a five-seat SUV launched in mid-May. The model delivered 5,949 vehicles within just 15 days of launch, helping Onvo surpass 10,000 monthly deliveries. The larger L90 SUV, which began deliveries earlier in the month, also contributed to the improved numbers. 

The company recently opened pre-sales for the refreshed 2026 L60, which will officially launch on June 11. The updated model adds LiDAR, Nio's in-house Shenji assisted-driving chip, a larger standard battery and more than 100 upgrades across software, safety and vehicle performance. Nio founder William Li has previously said that Onvo is expected to become the group's largest brand over time, accounting for 55% of total sales.

ES9 Gets Off To A Fast Start

While Onvo drove May deliveries, much of the market's attention has shifted to the newly launched ES9, Nio's flagship premium SUV. According to dealership-level sales data, Nio's retail network averaged 40 to 45 firm ES9 orders per store during the first 72 hours after launch across over 550 stores nationwide, implying that orders may have exceeded 20,000 units within three days, according to ChinaEVHome. 

The ES9 launched last week, with pricing that came in below consumer expectations. The vehicle starts at 498,000 yuan ($73,599 ), but can be purchased for 390,000 yuan through Nio's Battery-as-a-Service program. The pricing strategy appears to have boosted showroom traffic, with dealers reported footfall doubling after the launch, and 60% of visits coming from walk-in customers. Orders were concentrated in major EV markets such as Shanghai, Beijing, Shenzhen and Chengdu.

Early customer data also suggests that the ES9 is attracting both loyal Nio owners and new buyers. About 35% of orders reportedly came from existing Nio customers upgrading or replacing vehicles, while buyers overwhelmingly favored higher-end trims. More than 95% selected the Battery-as-a-Service option.

Nio's Premium Advantage

Nio's core premium brand delivered 20,013 vehicles in May, up more than 50% from a year earlier. The performance was driven by strength from the third-gen ES8 SUV, which delivered 11,475 units during the month and remained China's best-selling large SUV priced above 400,000 yuan for a fifth consecutive month.

The company's Firefly sub-brand added another 5,663 deliveries, up nearly 54% from the prior year. Firefly also surpassed 60,000 cumulative deliveries and continues to lead China's premium compact EV segment, according to the company.

Nio Doubles Down On AI And Swap Stations

Nio is also investing heavily in AI and infrastructure. William Li recently said that the company has increased spending on AI training compute fivefold this year after spending much of 2025 building the foundation for its Nio World Model, an assisted-driving system built around world models and reinforcement learning. Additional upgrades are planned throughout this year, including a major software rollout in June.

Additionally, Li reiterated plans to add 1,000 battery swap stations in China this year, despite a slower rollout pace so far. The company currently operates over 3,800 swap stations in China, and Nio expects deployment to accelerate in the second half as fifth-gen stations begin rolling out.
