Analysis

This probability represents whether Anthropic's valuation will exceed OpenAI's valuation at any point during 2026. The 90% likelihood reflects current market expectations that Anthropic will achieve a higher valuation than OpenAI within this calendar year. The main drivers are recent funding rounds and valuation announcements from both companies. Anthropic's December 2024 funding round valued the company at $60 billion, while OpenAI's most recent public valuation discussion occurred during its February 2025 funding discussions. The key uncertainty involves how each company's valuation changes through 2026—whether through new funding rounds, acquisition activity, or strategic events. No single scheduled resolution event exists; instead, resolution depends on public announcements or documented valuation data from either company during the year. Market participants are pricing in a high probability that at least one company will announce a new valuation that crosses this threshold.

  • Anthropic's December 2024 valuation of $60 billion versus OpenAI's last documented valuation and any new funding announcements either company makes in 2026
  • The timing and terms of potential new funding rounds for either company, which would establish official new valuations
  • Public statements or third-party valuations from industry analysts, investment banks, or acquisition discussions involving either company
  • Changes in AI market dynamics, deployment adoption rates, or revenue performance that could influence investor valuations of both companies
  • Whether OpenAI pursues a public listing or other corporate event that would establish a market-determined valuation in 2026

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
