What you get
TweetStream sends Polymarket Twitter alerts and Kalshi alerts over WebSocket from the X accounts you pick. The Polymarket and Kalshi APIs carry prices, order books, and orders, with no news or social feed. Pro, Scale, and Ultra Speed add supported Trump and White House Truth Social posts; active plans that already had Truth Social keep it.
- Politics and Trump markets
- With Pro, Scale, or Ultra Speed, monitor supported Trump and White House Truth Social posts alongside political X accounts for election, policy, tariff, and appointment markets.
- Company and regulatory events
- Follow agencies, companies, founders, and reporters whose first-party posts can move regulatory, launch, acquisition, or product markets.
- Kalshi alerts
- Point the same watchlist at Kalshi contracts. Start from each contract's resolution source and add the officials, agencies, and companies that would publish it first.
- Automated news trading
- Turn posts into structured classifier inputs that map a source, phrase, and confidence score to one or more markets.
- Human-in-the-loop alerts
- Send only the highest-impact social events to a desk or Discord channel with the relevant market and current odds attached downstream.

X post detection speed for prediction market accounts
Measured over the 30 days from Sep 21, 2026 to Oct 21, 2026, from each post's X timestamp to first receipt on a TweetStream server. The accounts are a fixed list TweetStream picked for prediction markets. An account is shown only when it posted at least 50 times in the window.
X posts only. Truth Social posts are not measured here. How TweetStream measures detection speed
What the Polymarket and Kalshi APIs provide
Checked October 3, 2026. Kalshi's REST and WebSocket APIs cover market data (readable without authentication), orders, portfolio, RFQ, history, and live sports, weather, and crypto price data. Polymarket's Gamma, CLOB, and Data APIs and its WebSockets cover markets, user activity, sports, and prices; its only social data is a tweet count and market comments. Neither venue publishes a news or social feed, so your bot needs a separate source for the posts.
Common questions
How do I build Twitter alerts for Polymarket trading?
For each market thesis, list the officials, politicians, founders, reporters, agencies, and companies most likely to publish the decisive information. TweetStream streams their posts, and your system maps each source and keyword to the relevant Polymarket market.
Can I get Kalshi Twitter alerts too?
Yes. The same feed works for Kalshi contracts. Map each contract's resolution source to the X accounts likely to publish it, then read market state and place orders through Kalshi's API. Kalshi has no news or social feed of its own, so the posts come from TweetStream.
Does TweetStream provide Polymarket prices or execute trades?
TweetStream provides real-time social events. Pro, Scale, and Ultra Speed include supported Donald Trump and White House Truth Social posts. Use Polymarket's APIs for market prices, order books, and execution, then combine the feeds inside your strategy.
How fast are TweetStream's Polymarket social alerts?
TweetStream publishes rolling server-detection percentiles for monitored X posts. Test your own watchlist and measure the full path through your classifier, network, and execution workflow.
TweetStream is independent and is not affiliated with, endorsed by, or sponsored by X Corp, Truth Social, TMTG, or Donald J. Trump. It is built for selected-account alert workflows. Use each platform's official access path when you need licensed access, write actions, compliance archives, or broad social listening. For developer setup, see the complete WebSocket example.
