How to short on Polymarket, and how to sell before a market resolves
There is no short button on Polymarket because there doesn’t need to be one: betting against an outcome means buying its NO shares, or selling YES on Polymarket US. You can also sell any position before the result at the current bid. How each works, what it costs, and how much you can lose.

Limit orders on Kalshi and Polymarket: how to use them and why they cost less
A limit order sets the price you are willing to pay or accept and waits on the order book until someone trades with it. It can save you the spread and, on Polymarket, the taker fee, at the risk of never filling. The order types each exchange offers, how fees treat them, and what happens to unfilled orders.

How does Kalshi work? Contracts, prices, settlement and sign-up
Kalshi is a CFTC-regulated exchange where you buy and sell yes-or-no contracts on events. Each contract pays $1 if its side is right and nothing if not, so its price in cents reads as a probability. Kalshi says you always trade with other members, not the exchange, and it earns a fee per trade.

How to contact Kalshi support: chat, email and what to include
Kalshi’s support runs through a chat in the app and on the website, with email as a fallback. There is no phone or text support. How to reach it, what to send for a deposit, withdrawal or settlement problem, and where to go if support can’t fix it.

How to make money on Kalshi, and why most traders don’t
Traders make money on Kalshi by buying contracts the market has priced too low, by selling before settlement, or by providing liquidity. The research is sobering: across 300,000 contracts, the average Kalshi contract lost about 20% of what was paid for it. Where the losses concentrate and what that implies.

Is Kalshi down? How to check, and the weekly maintenance window
Kalshi trades around the clock except a scheduled pause from 3:00 to 5:00 AM Eastern every Thursday. If it isn’t working at another time, its exchange-status endpoint tells you whether the exchange or trading is paused. Kalshi publishes no status page. How to check, and what to do meanwhile.

Is there a Polymarket waitlist? How to get access to Polymarket US
Polymarket.com is closed to US residents, so Americans use Polymarket US, a separate CFTC-regulated app. Its current sign-up has no waitlist step: you register, verify your identity and can trade once approved. What the sign-up asks for, the one place invite codes still come up, and who can join.

Kalshi’s 15-minute Bitcoin markets: how they work and settle
Kalshi’s 15-minute Bitcoin markets ask one thing: will Bitcoin’s price at the end of the quarter-hour be at least what it was at the start? Both prices are one-minute averages of CF Benchmarks’ Bitcoin index. How they open, close and settle, the fee type, and what bots need to know.

Polymarket fees: what you pay on Polymarket and Polymarket US
Polymarket charges a fee only when you take liquidity, never when your order rests on the book, and the rate depends on the market’s category. Polymarket US, the separate app for US residents, has its own fee formula and volume tiers. Both, with worked examples.

Polymarket historical data: price history and trades for backtesting

Polymarket taxes: what Polymarket and Polymarket US report, and what the IRS says
Polymarket US collects your Social Security number and has you consent to receive IRS Form 1099-B electronically. Polymarket’s international site issues no tax forms that we could find, and puts tax entirely on you. The IRS has not said how event-contract gains are taxed. What is known, and what isn’t.

Polymarket wallet tracker: how to look up any trader’s positions and PnL
Every Polymarket.com account is a public wallet, so anyone can see its positions, trades and profit, on its profile page or through Polymarket’s free Data API. How to look up a trader, which endpoints to use since the API moved to v2, and why Polymarket US accounts can’t be tracked the same way.

The CFTC tells prediction markets to stop blocking states: what it means
On 5 November 2026 the CFTC said federally regulated exchanges may not block traders by US state, and gave them 30 days to lift such restrictions or explain why they cannot. Several of those restrictions exist because state courts ordered them. What the CFTC said, why, where it collides with state orders, and what changes for traders.

Is demo.kalshi.co legit? Kalshi’s demo environment explained
Yes: demo.kalshi.co is Kalshi’s own demo exchange, run for testing with mock funds. Nothing you do there touches a real account, and no real money is paid out. What it is for, how it differs from kalshi.com, and the one mistake that can cost real money.

The CLARITY Act and prediction markets: what the bill says and what Polymarket prices
The CLARITY Act (H.R. 3633) is the crypto market-structure bill that splits oversight of digital assets between the SEC and the CFTC. It says nothing about prediction markets. People search for it alongside Polymarket because Polymarket runs a market on whether it becomes law in 2026.

The Kalshi API: market data, API keys, rate limits and the demo
Kalshi’s market data can be read over REST with no account and no key. Trading, live WebSocket feeds and your portfolio need an API key that signs every request. What each part does, the current endpoints and limits, and how to test safely in the demo first.

Bid vs ask: what the bid, the ask and the spread mean
The bid is the most anyone will pay right now; the ask is the least anyone will sell for. The gap between them, the bid-ask spread, is a cost you pay every time you trade at the market price — on a stock, a currency or a prediction market contract.

How does Novig make money? Fees, parlays and withdrawals
Novig builds no margin into its prices — that is the “no vig”. It earns instead from a taker fee on live trades and futures, a fee built into parlay prices, a 3% charge on card deposits, and affiliates that can trade as market makers. How each works, and how withdrawals work.
