Corporate Action Feeds Live on Pyth

Corporate action data for US equities is now available through Pyth Data Marketplace.

Splits, reverse splits, dividends, mergers, ticker changes, and other corporate actions across nine event types are available alongside Pyth price feeds, with upcoming and historical records for covered equities. Teams can explore the dataset and access options through the Pyth Terminal.

A stock comes with a calendar

A stock does not only have a price. It also has a calendar.

Companies pay dividends. They split their shares, or reverse-split them to remain above an exchange’s minimum price. They change tickers, spin off divisions, get acquired, or leave the market entirely.

Any token, perpetual contract, or collateral position that references a US equity inherits that calendar.

Traditional markets have managed these events for decades through reference-data services, transfer agents, clearing systems, and the overnight gap between trading sessions. Crypto markets rarely needed that infrastructure. BTC does not pay a dividend, and crypto assets do not generally undergo corporate actions such as stock splits.

That changes when venues begin listing equities onchain.

A price without the event is a wrong number

A price feed tells you what a stock is trading at. It does not, by itself, tell you why the price changed.

On June 7, 2024, NVIDIA closed at approximately $1,209 per share. After its 10-for-1 split took effect, the stock began trading at roughly $120 per share on June 10.

The company had not lost 90% of its value. Each pre-split share had simply become 10 post-split shares.

A system that saw only the price could interpret the adjustment as a crash. A system that also understood the corporate action could recognize it as a planned change in the unit of ownership.

Dividends create a similar problem. On an ex-dividend date, a stock’s price often adjusts lower by approximately the value of the distribution, all else equal. Without the event record, that movement can look like selling pressure.

Corporate action data is not an optional annotation. It is part of the instrument.

What is live

Corporate actions on Pyth cover all US equities across nine event types:

• Splits

• Reverse splits

• Cash dividends

• Stock dividends

• Ticker changes

• Delistings

• Rights issues

• Spinoffs

• Mergers

Each record includes the event type and effective date, with adjustment factors where applicable. The dataset includes both upcoming and historical events, allowing teams to prepare for scheduled changes and reconcile events that have already taken place.

Corporate action records are available through Pyth’s reference-data API alongside the Pyth Pro catalogue. A team already consuming Pyth equity prices can add corporate action data through the same Pyth integration instead of reconciling a second vendor’s feed and schema.

Teams can explore the coverage and access options through the Pyth Terminal.

Who it is for

Tokenized-stock issuers can track the events that affect token multipliers, supply, and distribution logic.

Perpetual venues listing equity contracts can identify splits, ticker changes, delistings, and mergers before they take effect, then apply their own contract rules.

Lending protocols accepting tokenized equities as collateral can distinguish a corporate action from an actual market move.

Prediction and outcome markets can reference an event record when a ticker changes or a company is acquired, according to their own contract terms.

Brokers and fintechs can source prices and corporate actions through one market-data integration.

In every case, the venue decides what an event means for its product. Pyth provides the data and the timing.
