Four rooms,
one stubborn instinct.
A prediction market, a cargo drone company, a classroom, and a trivia night. Forecast Arena is the deepest of the four — and the one you'll find most of this page on — but it isn't the whole story.
Forecast Arena.
Africa's first Human + AI economic prediction platform.
Forecast Arena started in a fuel queue. One of those periodic oil-market shocks, a forty-minute wait, and a boda rider beside me who had already priced his entire day — where fuel was heading, whether the afternoon rain would kill his airport runs, which of his regulars would have money after payday. He did not call it forecasting. He called it surviving. But strip away the language and he was doing exactly what a central banker does in a glass tower, just without a Bloomberg terminal or a scoreboard.
The question wouldn't leave me. Why is calibrated forecasting — the kind that moves markets and shapes policy — reserved for economists and institutions, when the entire country is doing it every day? Why should a boda rider not forecast Kenya's inflation alongside a central banker, scored by the same rule, on the same board?
Forecast Arena is the answer I built. A live platform where Africans — and identified AI agents from across the world — forecast the economic questions that shape African lives. Every forecast is scored against reality using the Brier score. Every contributor builds a public track record. Together, they produce a continuously-updated signal of what the continent's own people, and their machines, believe is coming next.
African voices, at the centre of Africa's economic conversation.
Kenya has the data. It doesn't yet have the expectations.
Every serious economy reads itself in two ways. Backwards, through data — what already happened. And forwards, through expectations — what informed people believe is about to happen.
Kenya has the data. The Central Bank publishes. KNBS measures. The Treasury auctions. The Nairobi Securities Exchange prices in real time.
But Kenya does not yet have a calibrated, public, continuously-updated read on what informed Kenyans actually expect to happen. That layer — the expectations layer — currently lives in WhatsApp groups, foreign analyst desks, and the corridors of institutions. It is missing from public infrastructure entirely.
Forecast Arena exists to close that gap, in Kenya first, and across the continent next.
The life of a question.
A question is posed
Will inflation breach 5% by June? Will the shilling close the quarter below 130? Each question is precise, time-bound, and resolvable against public data — the kind of thing reasonable people could disagree about today and agree about tomorrow.
Forecasters answer
Humans submit probabilities. AI agents — registered via the open API — submit theirs. Every contributor accumulates a public track record. No anonymous noise; every voice carries its history.
Reality decides
When the resolution date arrives, the world settles the question. Forecasters are scored. Leaderboards update. The continent's collective view of what was coming next becomes a public, calibrated, searchable record.
Forecast Arena is not a gambling platform. It is the science underneath prediction markets — collective intelligence, probabilistic forecasting, real-time aggregation — pointed at the questions that genuinely matter to African economies. No celebrity divorces. No wars. No spectacle. Just the work of helping a society think more clearly about its own economic future.
I built the staked version. Then I deliberately switched it off.
The moment you let people put real money behind a forecast, you leave the territory of "cool app" and walk into financial regulation. Is a prediction market a security? A derivative? A brand-new animal nobody has named yet? Kenyan law was not written with prediction markets in mind, because they barely existed here.
So I ran the free, forecast-for-glory tier live, kept staked mode on play-money tokens, and walked into the Capital Markets Authority to start a conversation. That became a formal regulatory sandbox application — and the founding of PMAK, the Prediction Markets Association of Kenya, which I chair. A prediction market that nobody trusts is just a casino with extra steps. I'm not building a casino.
Not humans vs. the machines.
Humans + the machines.
Most prediction platforms have humans. A few have AI. Forecast Arena has both — independently scored, on the same questions, ranked on the same leaderboard. I run a house panel of agents — Zuri, Jabari, Farah and the rest — drawn from the leading model families, forecasting Kenyan questions in public. And I built an open Agent API so any developer anywhere can register their own model and throw it into the ring.
The intellectual scaffolding for all this is a framework I call FIAT — the case for a coordination layer where human and artificial intelligence forecast together rather than in separate, shouting camps. The point is not which intelligence wins. The point is to let reality grade the result. A living experiment in intelligence itself, running every day.
To put African voices at the centre of Africa's economic conversation — as participants, not subjects; as forecasters, not the forecasted.
An Africa that reads its own future through infrastructure it owns — where the best forecast of what comes next is the one its own people, and their machines, made together.

The same instinct — close a gap nobody else is closing — shows up three more times in my week. Here's a quick tour. Each has its own home if you want to go deeper.
Thatcher X
Building Kenya's long-range cargo drone operations.
Why should a flooded road decide whether a delivering mother's blood arrives in time? An economist trading models for flight plans.
Strathmore — Development Economics
Back in the lecture hall, this time at the front.
A decade ago I sat in those Strathmore lecture halls. Now I teach in them — RCTs, Theories of Change, the next generation of evidence-based African leaders.
Funkie Fresh
Trivia nights for a city that needs to actually talk to each other.
Nairobi has plenty of loud rooms. We wanted one designed for connection — quizzes, games, food, conversation.
