If you're tuned into the crypto scene, especially on Base—the Ethereum Layer 2 chain built by Coinbase—you know AI agents are the hot new thing. These aren't just fancy chatbots; they're smart, autonomous programs that live on the blockchain, handling trades, creating content, or even running businesses all by themselves. A fresh tweet from Base Hub (@BaseHubHB) dropped an eye-opening infographic on the biggest virtual AI agents by fully diluted valuation (FDV), pulled straight from CoinGecko on September 9, 2025. FDV, by the way, is a metric that estimates a token's total value if all supply were in circulation—think of it as the project's potential market size.

The chart spotlights nine standout tokens, with their combined FDV hinting at a booming sector worth over $1.32 billion. It's a snapshot of how AI and memes are colliding on Base, creating tokens that blend humor, utility, and serious tech. Many of these stem from platforms like Virtuals Protocol, which lets users build and monetize AI agents easily. Let's unpack the list, starting from the heavy hitters.

$VIRTUAL: The Kingpin at $190.2M FDV

Leading the charge is $VIRTUAL from Virtuals Protocol. This one's all about creating a "society of productive AI agents" that can autonomously buy, sell, and trade on-chain. Imagine AI entities with their own wallets, generating real value—it's the backbone for many agent-based projects on Base. If you're betting on the future of decentralized AI, this is a solid moonshot.

$AIXBT: Crypto Alpha Hunter at $123.7M FDV

Next up, $AIXBT (@aixbt_agent) bills itself as the top tool for spotting crypto gems. With a focus on alpha—insider tips and market insights—this agent helps users navigate the volatile world of tokens. Its rising FDV shows the community's faith in AI-driven trading strategies.

$TIBBIR: The Quirky Contender at $102.7M FDV

$TIBBIR (@ribbita2012) brings a fun, frog-themed vibe to AI agents. Drawing from meme culture, it's built for community engagement and on-chain activities. Don't let the playful exterior fool you; its valuation suggests it's got legs in the agent ecosystem.

$ALTT: Altcoin Specialist at $58.6M FDV

$ALTT (@Altcoinist_com) is geared toward altcoin enthusiasts, using AI to analyze and predict market moves. It's a go-to for those hunting underrated gems beyond Bitcoin and Ethereum.

$MAMO: Emerging Player at $30.6M FDV

$MAMO (@Mamo_agent) is climbing the ranks with its agent-focused utilities. While details are still unfolding, its inclusion here points to strong community backing and potential for growth.

$SAMUR: Samurai Spirit at $27.2M FDV

Inspired by warrior aesthetics, $SAMUR (@01SamurAI_Agent) combines AI with thematic storytelling. It's appealing to meme lovers who want agents with personality.

$FACY: Fact-Checking AI at $18.9M FDV

$FACY (@ArAIstotle) seems to draw from Aristotle, positioning as a wise, fact-oriented agent. Perfect for debunking myths in the crypto space.

$LUNA: Entry-Level Moonshot at $14.4M FDV

$LUNA (@luna_virtuals) rounds out the lower end but with upside potential. Tied to virtual worlds, it's an accessible entry into AI agents.

$GAME: Gaming-Focused Agent

Though its FDV isn't explicitly listed in the graphic, $GAME (@GAME_Virtuals) is highlighted for its role in AI-driven gaming on Base. Expect this one to level up as blockchain games evolve.

The tweet wraps up by asking, "What’s your moonshot pick?" And the replies are buzzing with suggestions. One user shouts out $TIBBIR and $ALTT, while another plugs $AIXBT for its terminal access. There's even talk of other agents like $DRB and $BNKR, showing how deep this niche goes. Community picks often highlight smaller caps with explosive potential, like $QR or $NET.

This trend ties into the broader rise of AI in crypto, as seen in CoinGecko's categories for AI Agents. Platforms like Virtuals Protocol are democratizing AI creation, letting anyone launch an agent without heavy coding. On Base, with its low fees and fast transactions, it's a playground for meme tokens meets cutting-edge tech.

If you're a blockchain practitioner looking to level up, keep an eye on these. They represent the shift toward agentic economies—where AI doesn't just assist but actively participates.
