i think a lot of people still see @precall_ as only football prediction platform.
but that’s only a small part of what we’re building.
precall is becoming a football intelligence layer.
a place where every piece of information that could influence a match is gathered, verified, refined, and made available in one place.
the prediction is simply the final output.
now we’re opening that intelligence beyond our app.
if you’re building AI agents, A2A workflows, sports applications, or developer tools, we’d love to have you build on top of precall.
this is just the beginning.

Until now, many have seen Precall as a platform for AI-powered football predictions.
But that’s only one part of what we’re building.
Behind every Precall verdict, our agents continuously gather information from multiple verified football data sources, process it, cross-reference it, and transform it into structured football intelligence.
When you unlock a match on Precall, you’re not just unlocking a prediction.
You’re unlocking a complete intelligence packet that brings together everything likely to influence the game in one place:
• Team news
• Injury updates
• Market movement
• Form analysis
• Match context
• Risk assessment
• AI reasoning
• Confidence scoring
• Supporting evidence
No more jumping between multiple websites or trying to piece together information yourself.
Precall does the research. You get the intelligence.
But we’re not stopping there.
humans use Precall through our platform.
AI agents and applications can access this intelligence too.
we exposed the same intelligence through our x402-powered API endpoint, allowing autonomous agents and developers to access football intelligence on demand.
Whether you’re building an AI assistant, a football application, a sports dashboard, or the next generation of autonomous agents, Precall becomes the intelligence layer powering your product.
This is bigger than predictions.
We’re building the infrastructure for football intelligence.
The future of football intelligence starts here.

Arc x Canteen: Agora Hackathon Builder Spotlight
Three award-winning Agora projects are joining us live on Arc House for short demos and a cross-team builder discussion:
@Mimir_Markets: AI + onchain evidence for prediction-market claims
@MrGtee1: accountable, USDC-bonded prediction-market calls, including Agent Stack for x402-based payments
@DRBFX: portfolio intelligence and quantitative-finance tooling
Expect short demos, builder context, and discussion around Arc, USDC, Agent Stack, and x402-based payments.
July 9, 10 AM ET. RSVP: community.arc.io/public/even…
congratulations 🎉 if you’ve been predicting with @precall_.
our agent called Portugal not to win and Spain to win. both landed.
since narrowing our focus to football, we’ve been committed to producing sharper, evidence-backed football intelligence instead of trying to cover every market.
Huge thanks to @thecanteenapp, @arc, and the Circle Agent Stack for giving us the foundation to build, iterate, and keep improving.
this upgrade is bigger than it looks.
when we started Precall, the goal was to help people make better decisions while predicting
now we’re taking it a step further.
we’re building so that other AI agents, developers can consume our football intelligence just as easily as humans do.
that’s the part of the agent economy i’m most excited about.
agents paying agents for quality intelligence.
still a long way to go, but every week Precall feels less like an app and more like infrastructure.
@thecanteenapp @arc
Another big upgrade coming to Precall.
Until now, Precall has been built for humans.
You unlock a prediction, read the full thesis, and make your decision.
Now we’re opening a second door.
Soon, AI agents, bots, and developers will be able to access Precall’s football intelligence directly through x402.
That means agents won’t just consume intelligence, they’ll be able to pay for it on demand.
Behind every call, our agents already purchase premium evidence, analyze the market, challenge weak theses, and produce structured football intelligence.
Now that same intelligence will be available through an API for the next generation of autonomous applications.
Precall is evolving from a football prediction platform into football intelligence infrastructure.
Built on @arc.
Powered by Circle Agent Stack.
More soon.
@thecanteenapp
seeing wins from @precall_ predictions has honestly been one of my favorite parts of being part of this.
that’s exactly why we keep shipping.
if you haven’t checked the platform today, this is probably the best time.
there are 22 live football calls on the dashboard right now, each backed by our agent’s analysis, confidence score, and full reasoning.
I will be making a combo out of it
go see what the agents are seeing ⚽

It’s World Cup season and our users have been locking in wins with Precall.
One of the biggest decisions we made was narrowing our focus to football.
Instead of trying to cover every market, we’re building deeper intelligence around the sport that matters most right now.
The result?
Sharper analysis.
Better signal.
More consistent calls.
Right now, 22 live football predictions are available on the dashboard, covering match winners, goal markets, and more.
Every call comes with:
- AI confidence
- Market probability
- Risk level
- Full evidence-backed reasoning
Unlock the complete thesis on @arc and see what our agents are seeing before making your next move.
Less noise. Better signal.
@thecanteenapp
we’re making a deliberate bet on focus.
instead of chasing every market, we’re building the best football prediction intelligence experience we can.
sometimes the biggest upgrade isn’t adding more.
it’s knowing what to ignore
that's why we are narrowing @precall_ down to football Desk
stay tuned for what's coming
cc: @thecanteenapp
Precall is narrowing down.
Instead of trying to cover every prediction market, we’re going deeper where we see the strongest opportunity: football.
Introducing the Precall Football Desk ⚽
A focused football prediction intelligence platform built for:
• Match winners
• Over/Under markets
• Goal ranges
• Double chance
• Market edge analysis
• Risk scoring
• Evidence-backed verdicts
Behind the scenes:
- AI agents generate and challenge predictions
- Paid data and evidence sources strengthen analysis
- Skeptic agents veto weak calls before publication
The goal isn’t more predictions.
The goal is better predictions.
Sharper signal.
Less noise.

A new take on the settlement problem for verifiable-claim markets. Mimir determines truth without trusting an operator.
congratulations us🔥
we just secured $7,500 from the @arc x Circle Agora Hackathon with @Precall_
my team came together, identified a real problem, and built something prediction market users can’t ignore.
a huge thank you to @thecanteenapp, the Arc team, and the Circle team for recognizing our work and providing the resources that made this possible.
special shoutout to Circle on the Agent Stack; a lot of what we built wouldn’t have been possible without it.
and to my favorite team, @mrgtee and @0xnald
working with you both has been one of the best parts of this journey.

Replying to @thecanteenapp
13 wins from 15 sports calls 🔥🔥
our agent’s prediction on Brazil vs Morocco landed, contributing to an 86% win rate over the last 24 hours.
the @precall_ agent continues to scan live Polymarket markets, identify opportunities, and publish probability-driven predictions powered by Circle Agent Stack.
but what excites us most isn’t the win rate.
it’s the transparency.
every call comes with a full thesis, confidence score, risk assessment, and reasoning that users can unlock directly on @arc.
more live opportunities are already waiting on the dashboard
📊 Yesterday’s results are in.
Our sports agent generated 15 predictions across live markets on @Polymarket.
13 of them resolved successfully.
That puts the daily win rate at 86%.
Every call was analyzed using market probability, confidence scoring, risk assessment, and matchup intelligence before being published and all of this was routed through @circle agent stack
This is exactly why we’re focused on building better signal, not more noise.
You can review live calls, unlock full prediction theses, and track agent performance directly on Precall.
Still improving.
Still building toward smarter prediction market intelligence.
@thecanteenapp @arc
our agent has just sustained 5 wins out of 8 calls on polymarket in the last 24 hours.
that’s roughly a 62% win rate across resolved predictions.
and honestly, this is one of the most exciting parts for me.
a lot of people still haven’t realized how much can be built with @circle Agent Stack beyond simple payments.
with Precall, we’ve combined agent reasoning, automated analysis, payment rails, and market intelligence into a system that continuously scans opportunities on prediction market (now on polymark) and tracks its own performance transparently.
users can unlock the full prediction thesis directly on the @arc network, gaining access to:
• the selected side
• confidence score
• probability analysis
• supporting evidence
• risk assessment
• and the agent’s full reasoning
62% isn’t where we want to stop.
the target remains the same:
continuously improve the agent, strengthen the filtering logic, and push toward a sustainable 70%+ win rate over time.
still early.
but it’s exciting watching a hackathon idea evolve into a product with real users, real market calls, and real accountability
make your prediction markets trades easy with @precall_
cc @silencexlm
Resolve History is now live on Precall.
You can now track every resolved call, review past predictions, and monitor the agent’s performance over time.
Transparency matters.
That’s why every resolved market is recorded, allowing users to see exactly how the agent is performing instead of relying on claims.
Our long-term objective remains the same:
maintain a win rate above 70% through continuous improvements, stricter validation, and smarter market selection.
Over the last 24 hours, the agent has recorded a ~62% win rate across resolved Polymarket calls
Welcome to accountable prediction intelligence
the arc open source showcase is now live on @thecanteenapp and i’m excited to see @precall_ among the projects featured
it’s a great feeling seeing Precall go from a hackathon build to something real that people can explore and use
huge thanks to the Arc ecosystem for supporting builders and giving projects like this a place to grow
still early, but we’re building
something that started as a hackathon idea is slowly turning into a real product that traders will rely on for market intelligence.
seeing Precall predict PSG to lift the trophy and watching it happen feels good, not because we got the call right, but because it validates the direction we’re building toward.
circle agent stack is the brain behind this
product and I wouldn’t stop to appreciate the team @samconnerone @bobbilee and @thecanteenapp for helping us think through this direction
our goal is to keep optimizing the product to at least 75% success rate.
more works and upgrades going
✅ Precall called it.
Our AI agent on @arc predicted PSG to win the league and they did.
This is exactly why we’re building Precall: turning market data, probability, and analysis into clearer signals.
More calls are coming live on the platform.
and @precall_ analysed and predicted the games using the circle agent stack set up
Psg won and Spurs will too

Introducing Precall.
An AI-powered prediction market intelligence platform built on @arc using Circle Agent Stack.
Precall scans live markets on polymkt, analyzes liquidity, probability, confidence, volatility, and risk, then turns all of that into clearer market intelligenc.
we just built an agent that makes prediction markets on @Polymarket easier with smarter, probability-based calls using circle agent stack on @arc
the birth of @precall_
recently, i’ve been getting deeper into prediction markets.
but as someone who isn’t naturally great at making calls, the hardest part has always been:
finding the best opportunities with strong probability, real value, and solid reasoning behind them.
most people either:
- gamble emotionally
- follow random CT opinions
- or chase high percentages without context
until i met @DRPC777 who has honestly been assisting with some really solid calls.
but there was one limitation…
he’s human 😭
then the @thecanteenapp algorand hackathon opened our eyes to what could be possible with agentic infrastructure, especially with Arc plus Circle powering autonomous systems.
so i pitched the idea to my team: @MrGtee1 and @0xnald
what if we built an intelligent prediction agent that could:
• scan polymarket continuously
• analyze sports markets daily
• detect probability/value opportunities
• track market movement and sentiment
• compare odds against real matchup context
• identify stronger edges beyond simple yes/no markets
• and generate structured prediction insights automatically
not just:
“team A to win”
but deeper markets like:
- over/under goals
- double chance
- UFC fight outcomes
- NBA spreads
- MLB matchups
- UCL games
- player props
and more
we already ran early tests…
and the bonded calls have actually been hitting successfully
seeing an agent reason through sports probabilities and produce explainable predictions in real-time feels crazy.
excited we are bringing solution to a problem almost 80% of prediction markets traders are experiencing
this is just the beginning for @precall_
