Analysis
This market asks whether OpenAI will acquire Pinterest between now and the end of 2026—a 5% probability implies the market sees this as unlikely. OpenAI has pursued some acquisitions historically but has focused more on talent and partnership deals. Pinterest operates as a public company with its own business trajectory and strategic direction. The low probability reflects that no public signals point to acquisition discussions, OpenAI's capital tends toward compute infrastructure and research, and acquisition of a large social platform would face integration challenges and antitrust scrutiny. Resolution depends on whether OpenAI makes an official announcement of acquiring Pinterest before January 1, 2027. Any major strategic shift or partnership announcement from either company could shift market expectations, as would reporting on acquisition discussions.
- ›No public reporting or insider signals have emerged indicating acquisition discussions between OpenAI and Pinterest as of May 2026
- ›OpenAI's recent acquisitions and partnerships have emphasized AI talent, compute infrastructure, and research capabilities rather than social media platforms
- ›Pinterest is a publicly traded company with independent shareholders, board oversight, and existing business operations that would require board approval and disclosure of material negotiations
- ›An acquisition of this scale would likely trigger regulatory review and antitrust scrutiny given both companies' market positions
- ›The timeframe allows only approximately 7 months for announcement, negotiation, and public disclosure before the resolution deadline

Anthropic Crushes OpenAI in Best AI Model Race — Market at 96¢

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.
