Polymarket's 2024 Presidential Election Market Hits $1B Volume

Polymarket has archived its entire question history on an immutable blockchain ledger. Every prediction market question the platform has ever posed is now permanently recorded on-chain, creating a transparent and tamper-proof historical record. This move represents a significant step toward full on-chain transparency for prediction markets. The immutable nature of blockchain ensures that the complete archive of questions cannot be altered or deleted, providing researchers and users with a permanent reference. The initiative aligns with broader web3 principles of transparency and data permanence, allowing anyone to verify and analyze Polymarket's historical question data independently.

UMA's oracle network has experienced explosive growth in early 2026. The protocol processed over 50,000 assertions in just the first 25 days of January 2026 - a milestone that previously took nearly four years to reach (August 2021 to April 2025). **Key metrics:** - 50,000+ assertions in 25 days (January 2026) - Same volume previously took 45 months to achieve - Represents roughly 2,000 assertions per day This acceleration follows a pattern of rapid growth. In 2022-2023, UMA processed approximately 500 assertions monthly. By October 2025, the protocol was exceeding that monthly figure in a single day. The surge in assertion volume indicates increased adoption of UMA's optimistic oracle technology, which allows smart contracts to request and receive data in a trust-minimized way.
