Signet

Fees are transparent but add up on multi-leg trades.

Saved more using their bulk order tool for the Pharma merger arb.

Withdrew $150 from the Grammys market and had it in my bank before the after-party ended.

Took exactly seven minutes to complete KYC for my $50 Oscars trade.

Only missing a star because document upload stalled twice—reloading the page fixed it instantly.

Signet needs better filtering for World Cup markets.

Found myself scrolling past dozens of identical match winner listings while searching for halftime-specific props. After 17 minutes found the corner kick totals buried three layers deep. The markets exist—just need more logical categorization.

Presidential odds were competitive but not quite the best I've seen.

Odds on that product launch market beat what I saw elsewhere that week.

Had €300 riding on the Oscars upset - Signet's odds were consistently 2-3% more favorable than three other places I checked.

Only complaint is they don't offer as many entertainment specials.

I threw some money on an obscure court case about municipal zoning laws months ago - honestly forgot about it until the payout hit my account. Didn't expect much from such a niche market, but everything settled smoothly once the ruling came down. The resolution criteria were clear when I checked back, and the funds were available same day.

Account verification required six documents because I don't use social media.

Took 27 hours total - annoying but understandable. $400 bet on Labour beating Tories would've paid 3:1 elsewhere though.

Thought the Grammy markets would be dead when I first checked on my train ride, but placed limit orders that filled overnight.

Mobile execution works fine once you realize you gotta be patient with the less liquid categories.

Put $15 on an Oscars upset expecting payout delays—industry love their

Bet £750 on a celeb divorce at 22% likelihood, resolved correctly when announced eight days later.

Profits showed immediately but withdrawal took 31 minutes—would expect faster settlement at this volume. Detailed transaction log made verifying everything easy.

Signet offers markets on 73% of upcoming IPOs my model tracks versus competitors' 52% average.

Missing three niche biotech debuts I wanted exposure to though. Interface lacks proper sector filters—had to scrape the API to get clean data.

Placed £25 on Song of the Year during my commute - app loads faster than most exchanges.

One critique: position adjustment sliders need finer granularity when dealing with longshot bets under 5% probability.

Watched the Ethereum fork market with €750 across several positions.

The spread held under 1.5% through volatility, though I did hit some partial fills on larger limit orders. For small retail amounts like mine, liquidity seems optimized—never waited more than three minutes for a counterparty.

Used this for a Fed rate decision market with $120 at stake.

Compared to where I usually trade, the pricing was within 0.3% for most of the day. Sometimes liquidity drops on big moves, but fills were decent. Could use more granular expiry buckets - having just 'before meeting' and 'after' isn't always precise enough for monetary policy trades.

Was cautious about ETH upgrade wording until I saw Signet cite exact block heights.

Still cost me £20 in opportunity cost while triple-checking, but resolved flawlessly.

Took me weeks to finally deposit for that celebrity announcement trade.

Ended up using a debit card – processed in seconds. Interface could be clearer about limits before signing in though.

World Cup withdrawal cleared fast enough I almost missed the confirmation email.

Traded $400 on a celebrity baby name announcement - resolution terms were bulletproof with linked sources.

Could shave hours off research if they added more niche entertainment markets, but what exists is rock-solid.
