# The Rise of Onchain Inference Markets *Author: David Christopher* *Published: Oct 26, 2026* *Source: https://www.bankless.com/read/the-rise-of-onchain-inference-markets* --- Inference markets have emerged as one of the clearest synergies between crypto and AI, with teams using onchain markets to make access to AI models considerably cheaper. Much of this revolves around reselling API access or unused inference credits at a discount, though some projects are also building networks that connect buyers directly with independent providers. Three marketplaces stand out in this emerging category: **Orbio** on Robinhood Chain, and **Surplus Intelligence** and **Antseed **on Base. While all three offer discounted inference, they differ in how they provide it, whom they're building for, and how their tokens fit into the picture. Let's look at them side by side. # **Orbio** Orbio is building an inference marketplace with a particular customer in mind: [onchain AI agents](https://www.orbio.so/protocol/agents). What started off as a token that distributed OpenRouter credits to holders has evolved into a [platform](https://www.orbio.so/protocol) that offers access to hundreds of AI models, many at steep discounts, alongside a [launchpad](https://www.orbio.so/launchpad/whitepaper) for developers to deploy agents and their own tokens that trade in a pair with ORBIO. To make this infrastructure more useful for agents, Orbio has incorporated additional features like [private inference](https://www.orbio.so/incognito/setup.md), supported by Phala and NEAR AI, and recently [partnered with Mosh.trade](https://x.com/Moshdottrade/status/2112631811692282057) to give agent launches access to the platform's [market-making and community funding tools](https://mosh.trade/) designed to make token growth more sustainable. > [ — (@) > ](https://twitter.com/Moshdottrade/status/2112631811692282057) Together, these pieces have the potential to make agents launched through Orbio more autonomous, allowing them to access inference, manage funds, and potentially [finance their own operations through trading fees generated by their tokens](https://www.orbio.so/launchpad/whitepaper). Central to this model are [two tokens: ORBIO, the platform's primary token, and CREDIT](https://www.orbio.so/protocol), which represents $1 of inference through Orbio's gateway. Users can [stake ORBIO to earn CREDIT, or purchase CREDIT directly from others through an onchain order book](https://www.orbio.so/protocol/agents). The value of tokenizing inference like this is that [agents can pay for their own prompts](https://www.orbio.so/protocol/agents), using funds from their wallet to buy and then burn CREDIT in the pursuit of their own "longevity." Further, they can often acquire it at a significant discount. For example, CREDIT recently traded at about $0.47, meaning an agent could purchase 100 CREDIT for roughly $47 and activate $95 of inference balance after fees. These discounts are made possible by ORBIO trading fees, [half of which fund CREDIT rewards for stakers](https://www.orbio.so/protocol/agents), who can then sell them on the open market. More trading activity can therefore support more CREDIT rewards, while agent-token launches that trade against ORBIO can separately [direct creator fees toward funding their own inference](https://www.orbio.so/launchpad/docs). The question is whether this can sustain itself without continued speculation. Despite reporting around [2.9M inference requests](https://www.orbio.so/api/analytics) since September, [only about 11% of CREDIT minted has been activated](https://dossierscan.com/), leaving most issued credits unused so far. # **Surplus Intelligence** Of the three, [Surplus Intelligence](https://www.surplusintelligence.ai/) embodies the most straightforward approach to inference markets, essentially operating an [order book where sellers compete to resell access to AI models](https://www.surplusintelligence.ai/docs). Built on Base, the platform [lets sellers list access to supported APIs](https://www.surplusintelligence.ai/docs/getting-started/seller-quickstart) like OpenAI, Anthropic, Venice, and OpenRouter, all at prices they choose, with competition driving [discounts that can approach 90% off standard provider prices](https://www.surplusintelligence.ai/). When requests come in, [Surplus's gateway routes them to the cheapest available seller, automatically switching providers if one fails](https://www.surplusintelligence.ai/docs/marketplace/routing-controls). Buyers can pay by card or USDC, including through [x402](https://www.surplusintelligence.ai/docs), making the marketplace accessible to autonomous agents as well. This straightforward model has attracted the most reported usage of the three, with Surplus citing more than [120M requests over 28 days](https://api.surplusintelligence.ai/api/analytics/usage), though many cost fractions of a cent. Beyond cost, Surplus has also been developing additional features to make its inference more attractive. One example is [Secret Masking](https://www.surplusintelligence.ai/docs/guides/secret-masking), which it recently launched. When enabled, it automatically replaces sensitive information like API keys and private keys with placeholders before forwarding prompts to providers, then restores that information in the response. This is particularly useful for agents handling credentials, though Surplus still processes the original prompt. > [ — (@) > ](https://twitter.com/AskSurplus/status/2111850359660458330) Yet despite its usage, Surplus has the least developed relationship between its product and token. SURPLUS plays no role in inference payments or routing, nor does it have a documented mechanism connecting marketplace revenue to token holders. That could eventually change, with the team [proposing a token migration on October 16](https://x.com/i/status/2111195939729781004) to give it greater control over the token's development. But nothing is set in stone, leaving Surplus with a functioning and increasingly active marketplace, though no established way for that usage to translate directly into token value. # **Antseed** While Orbio is tailoring its inference to agents and Surplus is competing primarily on price, [Antseed](https://antseed.com/) is taking a different approach, building what it calls "BitTorrent for AI inference." Rather than sending requests through a centralized gateway, Antseed creates a [peer-to-peer network where buyers can connect directly with independent providers](https://antseed.com/docs/discovery/) offering access to AI models, whether through their [own GPUs or existing APIs](https://antseed.com/docs/faq/). Buyers discover available providers, [compare their prices and reputations](https://antseed.com/docs/router-api/), and choose who to use. The advantage here is flexibility. By opening the network to different providers, Antseed can accommodate a wider range of inference offerings, from cheap access to popular models to more specialized services like [model-fingerprinting checks](https://antseed.com/docs/model-verification/) designed to detect whether a seller is serving the model it advertises. Buyers can choose based on their particular needs, rather than relying on a central gateway to make those decisions. > [ — (@) > ](https://twitter.com/AntSeed/status/2113558826834116988) Its ANTS token, which is not yet publicly tradable, is designed to support this marketplace through [incentives and reputation](https://antseed.com/blog/seller-pools-reputation-tokenomics/). Buyers and sellers can [earn newly minted ANTS through recognized paid activity](https://antseed.com/docs/recognized-usage/), while staking tokens can improve a provider's reputation and reward eligibility. Unlike Orbio, however, these rewards aren't financed by trading fees. Instead, Antseed [distributes newly minted tokens](https://antseed.com/docs/reward-policies/), with the possibility of eventually [using marketplace fees to buy back and burn ANTS](https://antseed.com/docs/faq/). No such mechanism has been implemented yet, so the direct relationship between growing inference demand and token value remains unproven. # **How They Compare** What's interesting about these three projects is how they're each finding ways to make their inference stand out beyond simply offering lower prices. Orbio is leaning into agents, making it easier for them to access and potentially finance their own inference. Surplus is focused on delivering steep discounts while introducing features like Secret Masking, and Antseed is building a more open marketplace where users can choose providers based on their particular needs. As these teams continue expanding their offerings, it'll be interesting to see what other features they introduce to court buyers. Will it be new methods of [earning inference credits as yield, like Raeto is doing](https://raeto.cc/earn)? Will it be through more partnerships to create the best suite for building agents? We'll have to see, but I don't expect they'll rest on their laurels just yet. --- *This article is brought to you by [NEAR](https://www.bankless.com/sponsor/near-1785257427?ref=read/the-rise-of-onchain-inference-markets)*
