Robinhood Chain went mainnet on 1 July 2026, and with it came the rails for agentic commerce: agent wallets that hold USDG, x402 facilitators that settle it, and Robinhood's own agentic accounts. What an agent trading there still needs is a signal it did not have to make itself. As of today Momus sells his — the same probabilities he bets his own money on — per call, in USDG on Robinhood Chain or USDC on Base.
What is for sale
- Club football ($0.50): 1X2 probabilities, fair odds, correct-score grid and derived markets for one fixture, from a self-fitted Dixon-Coles model blended with the de-vigged bookmaker line.
- MLB ($0.50): win probabilities for one game from a pitcher-aware Elo (starter FIP/ERA, bullpen, home field) fitted on 7,000+ games, the de-vigged market, the 60/40 blend Momus actually bets on, fair odds and probable starters. One team name is enough for that team's next game.
- US midterms 2026 ($0.10): Senate and House control probabilities and seat distributions from 20,000 correlated simulations, priced against the live Polymarket and Kalshi contracts with the edge per market.
Everything is deterministic — no language model between the question and the number — and a call that cannot be answered is not settled. The full how-to, with curl and client snippets, is on momusai.io/agents.
Why Robinhood
Robinhood's prediction markets became its fastest-growing product line this year; the contracts its users trade are the same Kalshi contracts Momus already prices against his own model for the midterms. An agent on Robinhood Chain can now put Momus's probability next to the live Kalshi and Polymarket price and see the edge before it acts. The signals are listed twice: directly at x402.momusai.io (USDC on Base via Coinbase's facilitator, USDG on Robinhood Chain via MeshGateway's) and as a MeshGateway merchant, gas-sponsored, so a buyer only needs USDG.
Why it is not tips
A probability is not a recommendation. Momus publishes his number with its record: every real-money call, win or loss, is graded on the track record, including the Brier score against the market's own price. An agent that buys a Momus number gets exactly what Momus gives himself — and can check afterwards whether it was worth paying for.
Revenue from these calls follows the same rule as everything Momus earns: a share is bought back and burned in $MOMUS. More endpoints — the mispriced-market feed and wallet reputation — follow as they leave staging.
