Market context
The market tracks whether Credible Finance secures its target commitment threshold for its public sale on MetaDAO before the raise closes in August 2026. Credible has already secured $2.315 million in soft institutional commits, with a fundraising range set between $2 million and $4 million, making the 99% implied probability on Polymarket a reflection of this near-certain floor [2].
Historically, onchain fundraising mechanisms on Solana with institutional backing and verified soft commits rarely fail to hit minimum thresholds, particularly when the minimum is already exceeded by pre-raise commitments. Comparable MetaDAO raises, such as Hurupay’s uncapped USDC mechanism with a fixed minimum, have consistently resolved positively once initial institutional interest is confirmed [6]. The divergence here lies in how platforms price certainty: Polymarket uses decimal odds (99¢) while Kalshi and Betfair often express similar confidence as implied probabilities or fractional odds, with Kalshi requiring KYC and US residency, whereas Polymarket and Smarkets offer broader global access with different fee structures [1][5].
Traders should monitor the live “committed” figure on the official Credible sale page, as the market resolves to Yes if the threshold is met at any point before the deadline, regardless of later refunds [2]. Key catalysts include Credible’s curated raise launch on 13 July, powered by Solana, and any updates on revenue run rates following their $700 million in processed volume [7]. Institutional momentum, evidenced by Paradigm’s $5.9 million token acquisition and $2.2 million earlier investment in MetaDAO, further reinforces the likelihood of the threshold being breached [5][10].
Methodology
We read Total commitments for the Credible public sale on MetaDAO from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.
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.
FAQ

- 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.

- What about Smarkets as an alternative?
- Smarkets is a UK betting exchange with a lower default commission (2%) than Betfair. Liquidity on political markets is below Polymarket, comparable to Kalshi. Geo-blocked in many jurisdictions.
- Which platform is accessible globally?
