META PLATFORMS $META IS PLANNING TO LAUNCH A CONSUMER AI AGENT IN THE COMING WEEKS • • The project internally named "Hatch "is the consumer version of Meta's internal OpenClaw AI agent. • • Meta is also targeting October for its next AI model, called "Watermelon." - The Information
According to sources familiar with the matter, Nvidia reached a $6 billion deal last week to create one of the world's most powerful open-weighted AI models, competing with heavyweight Chinese models such as DeepSeek and Kimi K3.
Nvidia has reached an agreement with AI startup Poolside:
- Pay $6 billion to license its technology (Model Factory) and hire over 100 engineers.
- Invest an additional $1 billion, acquiring a stake at a pre-fundraising valuation of $12 billion.
- Most engineers will join Nvidia's Nemotron open-source weighted model project, aiming to create one of the world's most powerful open-source models.
Purpose:
To compete with open-source models from Chinese companies like DeepSeek and Kimi, while also challenging closed models from OpenAI and Anthropic. Open-source models are low-cost and easily customized, helping to build an open AI ecosystem in the US.
Poolside's founders (including the former CTO of GitHub) will not join Nvidia, and the company will continue to operate independently. This reflects Jensen Huang's desire for Nvidia to maintain a dual-track strategy of hardware and open-source models to ensure market dominance.
The agreement stems from Poolside's previous failed fundraising and insufficient computing resources, making Nvidia an ideal partner.
Nvidia acquires Poolside AI license for $6 billion, hires over 100 employees, and recreates the Groq model.
Last week, @SpaceXAI released Grok 4.6, its new frontier model designed for coding, agentic tasks, and knowledge work. • • Independent evaluations suggest that SpaceXAI has returned to the AI frontier competition based on both performance and cost. • • The economics of Grok 4.6 seem particularly compelling for AI agents. Artificial Analysis estimates that Grok 4.6 costs $0.84 per task on its Intelligence Index, placing it on the Pareto frontier for intelligence-versus-cost. • • More from @MattarARK in this week's newsletter
DEEPSEEK CHALLENGES ANTHROPIC WITH NEW AI MODEL • • DeepSeek has unveiled an experimental multimodal AI model capable of analyzing images, screenshots and text while performing autonomous tasks. • • Called DeepSeek-V4-Flash-Vision-Exp, the model reportedly approaches Anthropic’s Opus 4.8 in multimodal agent performance while retaining DeepSeek’s latest text, reasoning and agent capabilities. • • The release highlights intensifying U.S.-China AI competition, with Chinese developers increasingly offering advanced models at lower costs.
What is this event about?
This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on October 31, 2026, 12:00 PM ET.
Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies first place under this ranking.
The resolution source for this market is the arena.ai Text Arena (Overall). If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".
