Market context
STRC would need a one-minute TradingView candle high of at least $100 before 31 December 2026, so the market is really asking whether the preferred can print at the top of its recent range rather than merely trade near it. TradingView shows STRC around the mid-$80s to high-$80s in early July 2026, while Yahoo’s quote page shows a 52-week range up to $100.42, which means the strike level is not unprecedented but still outside the current tape.[18][19][20]
The clearest historical guide is that STRC has already approached the threshold before; both Strategy’s own material and recent coverage say the company’s stated objective is for STRC to trade around $99-$100, and Yahoo reports that Saylor has repeated that target as the stock recovered from a June low.[2][15] That helps explain why some external models and market commentary have treated $100 as a plausible upside case, with one analyst note cited by Yahoo putting fair value near $96 and another discussion noting the stock had been priced well below par when those views were published.[12][4][3]
For traders comparing Polymarket with Kalshi, Betfair or Smarkets, the practical differences are in how the bet is priced and accessed. Polymarket typically shows a straight implied probability, so a 0% YES quote suggests the market is effectively not assigning any visible chance; exchange-style books such as Betfair and Smarkets usually express this as decimal odds, with commission taken from winnings rather than embedded in the quote, while regulated US venues like Kalshi price in probability terms but require identity checks and jurisdictional access that can be tighter than offshore alternatives. On this market, the main catalysts are not earnings per se but any STRC-specific corporate actions, capital-structure updates, or Bitcoin moves that shift sentiment around Strategy’s preferred shares, since the stock’s narrative is tightly linked to the firm’s balance-sheet and crypto exposure.[2][5][7]

Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
UK Frequently Asked Questions
- What does Polymarket cost vs Kalshi?
- Polymarket: 0% fees, only Polygon network costs (~$0.01/trade). Kalshi: up to 7% per trade plus spread. For high-frequency traders, Polymarket is dramatically cheaper.
- Which platform has the deepest liquidity?
- Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
- Is Betfair a Polymarket alternative?
- Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.
- Polymarket vs Betfair Exchange: which is better for UK prediction trading?
- Betfair Exchange offers UKGC regulation, GBP settlement, and potentially tax-free winnings — but focuses on sports and politics only. Polymarket has deeper liquidity, 0% platform fee, global event coverage, and crypto/geopolitical markets Betfair doesn't offer. For UK traders: Betfair for regulated GBP sports markets; Polymarket for broader, global prediction events.
- Is Kalshi available in the UK?
- Kalshi is a US CFTC-regulated prediction exchange. UK residents can create accounts but must use USD and US payment methods. Kalshi's product range overlaps with Polymarket but with lower liquidity on most contracts. For UK traders, Polymarket typically offers better prices due to higher global volume.
