At a glance: AIsphere, the company behind PixVerse — incorporated in Singapore, with operations in Beijing and Shanghai — closed a $439 million Series C extension led by Alibaba, announced July 13–14, 2026. The round pushes the company’s valuation past $2 billion and funds a pivot from AI video generation into real-time interactive worlds, a proprietary Game Engine, and AI-powered live entertainment.

We research these topics — we do not have access to private financial data or insider sources. All figures cited here come from public reporting by TechCrunch, Yahoo Finance, Caixin Global, TechTimes, and company announcements linked throughout.
We covered PixVerse in May 2026 when the company was sitting on a $300 million Series C, 100 million users, and a unicorn valuation. In the two months since, the company raised another $139 million, added 50 million more users, and announced that it is no longer primarily an AI video company.
The extension round
AIsphere closed a Series C extension bringing total Series C capital to 2.98 billion yuan — approximately $439 million. The extension was led by Alibaba — TechTimes reports Alibaba also signed a commercial deployment agreement alongside investing — with new investors including Lollapalooza Capital, Ivy Capital, Grand Mount Capital, Eastern Bell Capital, Mirae Asset, BlueFocus, and CloudAlpha. Existing investors iGlobe Partners and OCBC’s LionX Ventures participated.
Alibaba’s involvement tracks its broader strategy of backing Chinese AI infrastructure plays — it has also backed Moonshot AI in the same period. For PixVerse specifically, Alibaba led the company’s $60 million Series B in September 2025; it was not a participant in the intervening $300M Series C tranche (led by CDH Investments), so leading this extension marks a return rather than continuous involvement.
The post-money valuation is above $2 billion. TechCrunch notes this puts PixVerse above $2 billion; the company has not disclosed the precise figure.
What’s changed since May
The raw numbers have moved substantially in two months:
- Users: 100 million registered → 150 million registered, across 177 countries (from 175)
- Valuation: $1B+ → $2B+
- Round total: $300M → $439M
More significant than the user growth is the strategic announcement accompanying the extension. PixVerse’s official announcement is explicit: the company is moving from AI video generation to interactive entertainment. The two products launching with the extension — the PixVerse Game Engine and a real-time interactive livestreaming platform — define what that means in practice.
R1: the foundation
Everything PixVerse is building now rests on R1, the company’s real-time world model launched in January 2026. Where traditional video generators produce a fixed clip in response to a prompt, R1 produces a continuous, interactive stream that responds to user input during the session.
R1’s architecture combines native multimodal processing, autoregressive memory for continuity across frames, and a low-latency response engine designed to behave less like a render queue and more like a responsive environment. The practical result: scenes evolve indefinitely, and a user or system can steer them in real time.
Since launch, R1 has received two meaningful updates. A February 2026 release added synchronized audio generation — ambient sound and voice aligned with visual output in real time. A later update introduced shared worlds and personalized avatars: multiple users can enter and shape the same AI-generated environment simultaneously, with the world running continuously and no session limit.
The PixVerse Game Engine
The Game Engine applies R1 to game creation with a specific architectural choice: separating abstract game mechanics from their visual expression. A player interacts in natural language, describing what they want to do. The engine processes that intent and generates both the visual environment and the mechanical response (physics, object interactions, outcomes) in real time.
The consequence is that games built on the engine are not constrained by a fixed set of pre-designed options. A player who wants to go somewhere the designer never anticipated doesn’t hit an invisible wall — they get a generated environment. TechTimes notes that the company is entering this space at a moment when OpenAI’s Sora has been discontinued, removing one potential competitor from the interactive world model segment.
Interactive livestreaming
The second new surface is real-time interactive livestreaming. PixVerse’s own announcement describes it directly: “AI-generated characters respond to viewer input live, opening new possibilities for interactive entertainment and virtual hosting.” The announcement does not specify whether that input is text, voice, or both.
The livestreaming use case is particularly commercially interesting in markets where virtual character streaming (China’s VTuber and digital host market; Japanese idol streamers; Southeast Asian live commerce) already has substantial audiences. A platform that can produce AI virtual characters that respond naturally to live viewer input competes with human streamers on one axis (availability, scalability) while introducing capabilities no human streamer can offer (simultaneous personalization, language switching, no scheduling constraint).
Competitive context
PixVerse’s pivot lands in a market that shifted significantly in early 2026. OpenAI discontinued Sora and Sora 2. Runway, Kling (from Kuaishou), and Hailuo (from MiniMax) remain as competitors in pure video generation. TechTimes reports that DeepMind’s Genie 3 is the closest research-level predecessor to R1, but operates as a research asset rather than a commercial product — none of PixVerse’s direct competitors has announced a shipping R1 equivalent.
The game engine space is more nascent. TechTimes reports PixVerse is “the only company with a commercial R1-type product available to partners.” If PixVerse’s Game Engine delivers on the framing in the announcement, it will be the first commercial offering in this category.
What the capital funds
The official announcement frames the extension capital as funding three parallel workstreams:
- Scaling R1 infrastructure for real-time applications at 150M+ user scale
- Building and launching the Game Engine
- Launching and growing the interactive livestreaming platform
The company previously operated with 57 employees. By the time of the extension announcement, TechTimes reported PixVerse employed 150 people across offices in Singapore, Beijing, and Shanghai — roughly triple the earlier count. Whether the extension capital itself funds further headcount growth or concentrates on compute infrastructure is not specified in the announcement.
The bottom line
AIsphere has moved from an AI video generator that happened to have a large user base to a company explicitly building the infrastructure layer for interactive AI worlds. The Series C extension gives it $439 million total and Alibaba as a strategic investor in that bet.
The R1 architecture is the key differentiator. A platform that generates continuous interactive environments is categorically different from one that generates clips. Whether the Game Engine and livestreaming products can translate that technical distinction into durable market position is the question the next 18 months will answer.
