Price basis matters
Price-market targets are in USD per Stock Token. Oracle feeds include the corporate-action multiplier and reflect token total return. REST quotes shown in asset hubs are raw underlying-equity prices. They are not interchangeable.
INSIDER never divides an old oracle round by today’s multiplier. Relative-return and higher/lower markets compare the same token-denominated basis at both timestamps. Strict comparisons mean an exact tie resolves NO.
The observation rule
A price adapter accepts the first contiguous oracle round at or after the agreed timestamp, within a 24-hour observation window. The previous round must precede that timestamp. Positive answers, round completion, heartbeat spacing, token oracle pause and sequencer recovery checks are enforced.
Current adapters reject feed phase boundaries rather than guessing missing historical rounds. A valid record must be submitted no later than seven days after the observation window. Anyone may submit it. If none is recorded by that fixed deadline, settlement becomes invalid.
Missing data and invalid markets
An invalid market pays one-half collateral unit per YES or NO share, rounded down in collateral base units. This is an equal-outcome settlement, not a refund of each trader’s purchase price. Trading losses may remain. No admin can seize the pool or unilaterally cancel a price market.
Touch-target observations
Touch-target creation requires an approved touch adapter. Any participant or a sponsor-operated keeper can advance coverage. YES needs a qualifying recorded crossing; NO requires a complete, contiguous, heartbeat-valid series through expiry. Missing coverage after eight days resolves invalid. These are recorded oracle observations, not continuous exchange-price monitoring.
Corporate actions and dividends
REST corporate-action records cannot directly prove outcomes onchain. The optimistic adapter exposes the proposer, public source and evidence hash. An authorized resolver proposes within seven days after expiry. Anyone can dispute within three days.
Governance explicitly decides disputed outcomes and publishes an evidence hash. If it does not adjudicate within fourteen days of the proposal, the market is invalid. This mechanism trusts the configured resolver and governance; it is not a trustless price oracle.
Corporate templates support completed forward splits, reverse splits, cash dividends and stock dividends. Dividend-threshold markets compare one cash dividend's USD-per-share rate, without summing multiple events. Conditions commit to the exact asset, action and complete UTC-day interval, with an inclusive start and exclusive expiry. The official processDate is a processing date, not an announcement or dividend payable date. The evidence helper identifies positive matches; absence from a limited feed is never an automatic NO verdict. Approved adapters and operating roles are required before creation.
Audit the result
Market pages display the immutable adapter and contract. Read the contract, observation event or proposed evidence on Blockscout before trading. A frontend label is never the final authority for settlement.
