Why this matters:
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.

Key factors:
- 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

Contracts:
- Will OpenAI announce acquisition of Pinterest before Jan 1, 2027?: OpenAI — 3¢ Kalshi $105 (weight 100%)
- Will Amazon announce acquisition of Pinterest before Jan 1, 2027?: Amazon — 3¢ Kalshi $0 (weight 0%)

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
