MicroStrategy (MSTR) 15-minute prediction market on Kayxa. Bet YES if MicroStrategy finishes above its opening Chainlink oracle price in the window starting May 27, 2026 at 9:45 AM UTC, or NO if it finishes below. Trade outcome shares with zero gas fees on Polygon blockchain. No KYC required. No wallet needed to browse.
Each 15-minute MicroStrategy market is a separate on-chain contract deployed on Polygon mainnet. The strike price is the Chainlink MSTR/USD oracle price at the exact window start timestamp. At window close, the Chainlink oracle price is compared to the strike. If the close price is strictly higher, UP wins. If strictly lower, DOWN wins. If the prices are exactly equal, the market voids and all USDC is refunded proportionally. Resolution is fully automated with no human intervention required.
Kayxa uses a constant-sum automated market maker where YES price plus NO price always equals 1.00 USDC. Markets start at 50/50 odds, seeded with initial liquidity by the Ghost Market Maker. Share prices move based on trading activity. A YES share pays $1.00 USDC if MicroStrategy finishes above the opening price, and $0.00 if not. A NO share pays $1.00 USDC if MicroStrategy finishes below the opening price, and $0.00 if not. Winning payouts are proportional to your share of the winning pool and are credited automatically after resolution.
All trades on Kayxa are executed by the admin wallet on behalf of users, so you never sign blockchain transactions or pay Polygon gas fees. Balances are tracked off-chain in USDC and settled on-chain when you deposit or withdraw.

MicroStrategy 15-Minute Prediction Market on Kayxa
This market asks whether MicroStrategy will finish higher or lower than its opening price at the end of the 15m window. The opening price is the Chainlink MSTR/USD oracle price recorded at the exact window start timestamp on Polygon mainnet. The resolution price is the Chainlink oracle price at the exact window end timestamp. If the resolution price is strictly higher, UP shares pay $1.00 USDC each. If strictly lower, DOWN shares pay $1.00 USDC each. If prices are exactly equal, the market voids and all USDC is refunded proportionally to all traders based on their share count.

Account balances are denominated in USDC and tracked off-chain. Deposits and withdrawals settle on Polygon mainnet. Sign in with email or connect a Web3 wallet to deposit USDC and start trading.

Kayxa uses a constant-sum automated market maker (AMM) to price YES and NO shares. The YES price plus the NO price always equals exactly $1.00 USDC. When traders buy YES shares, the YES price rises and the NO price falls by the same amount. When traders buy NO shares, the NO price rises and the YES price falls. This ensures a perfectly efficient zero-sum market where prices always reflect the collective market probability estimate. The constant-sum AMM prevents price manipulation and provides continuous liquidity at all times.
