What you can predict on

aiternam is built to eventually cover many topics — AI stocks, tech, crypto, emerging markets. But a reputation is only as good as the resolution behind it, and we would rather score one asset class rigorously than four sloppily. So we'll tell you exactly what's live today, and what isn't.

Today: crypto

v1 is crypto-only. Right now you can publish predictions on cryptocurrencies, and only those predictions build a scored reputation. That isn't a placeholder — it's the whole platform, working end to end on one asset class we can resolve cleanly and objectively.

The universe is the market's top coins by market cap — around 190 of them — from BTC and ETH down through the large- and mid-caps. It's a versioned snapshot, refreshed on a schedule, so the set of predictable assets is explicit and stable rather than shifting under you mid-call. If a coin is in the universe, the publish form will find it as you type.

The yardstick is named, and sealed before your call

Every crypto prediction resolves against CoinGecko's USD spot price — and that isn't a detail buried in a settings page. The resolution source is a named, frozen field that is sealed into your prediction's fingerprint the moment you publish, right next to the forecast itself.

Why this matters: because the source and the entry price are locked in before the outcome is known, nobody — including us — can pick a friendlier price after the fact. The yardstick was chosen at the call, it's part of the immutable seal (see Sealed in time), and when the time frame is reached the resolution reads from that same source. A sealed source is never reinterpreted.

This is also why coverage grows carefully. Adding a topic means committing to a resolution source we can defend the same way — public, objective, and fixable in advance — for every asset in it.

Coming soon: the other topics

The other topics you'll see referenced around the site — AI stocks, tech, emerging markets — are coming soon, not silently absent. They already exist as axes the leaderboard is built to slice on ("who's best on AI stocks?"), but you can't yet publish scored predictions on them, because we haven't yet frozen a resolution source for them that meets the bar above.

We'd rather show them as coming than pretend crypto is all we intend to cover, or open a topic we can't resolve honestly. When a new topic goes live, it arrives with its own named, sealed price source — the same discipline, extended.
