  • Nof1

    Led · Equity · May 2026

    Nof1 operates an artificial intelligence trading laboratory that runs a public experiment called Alpha Arena, which pits frontier AI models from firms such as OpenAI, Google, Anthropic, xAI and Alibaba against each other in real financial markets. In Seasons 1 and 1.5, eight models each received $10,000 in real capital and competed across 32 sets of results, with models finishing profitable only six times. The lab's stated purpose is to evaluate how effectively AI systems can learn to allocate capital and manage risk under market uncertainty. Nof1 plans a Season 2 in which it will develop its own models equipped with web search, extended reasoning time, and multi-step execution. After Season 2, the company intends to launch a consumer platform featuring its frontier models and what it describes as the world's first coding agents for markets. The lab says it uses an open-ended AI architecture intended to continually improve and eventually outperform human and algorithmic traders.

  • SUI

    Led · Equity · Nov 2025

    Sui operates a layer-1 blockchain that emphasizes high throughput and low-latency transactions for decentralized applications, particularly in payments. The network recently entered a strategic partnership with Google to co-develop the Agentic Payments protocol, aimed at enabling more efficient on-chain payment experiences. Sui positions itself as an infrastructure provider that can support large-scale institutional and retail adoption of crypto payments. Beyond technology development, the project is actively courting strategic alliances and institutional backers to accelerate ecosystem growth. Its latest capital infusion totals $450 million, signaling strong investor confidence and providing ample runway for continued R&D and ecosystem incentives. Market commentary highlights growing institutional interest across the broader Sui, Sei, and Chainlink ecosystems, reinforcing Sui’s traction among large stakeholders. The company’s roadmap appears focused on rolling out Agentic Payments and expanding developer engagement, while leveraging fresh capital to scale network security and user acquisition.
