10 September 2026.

NYC starts cloudy, then turns sunny: 86°F today, 68°F tonight, with no rain in the forecast. Dress for late summer; the convincing autumn weather remains a shop-window installation. NWS

Reporting checked through 6:18 a.m. ET.

Coco borrowed Tiafoe’s escape route. Gauff saved two match points and beat Mirra Andreeva 2–6, 7–6(7), 6–2 yesterday, explicitly crediting Tiafoe’s comeback as inspiration. One saved match point involved a 39-shot rally. She now faces Elena Rybakina in today’s US Open semifinals: the reprieve has not produced an easier assignment. Reuters

The August loser to add is Arini’s flagship. Today’s FT reports a loss of close to 1% in August, following almost 8% in July, leaving it more than 8% down this year. Yet Arini’s Credit Opportunities and direct-lending funds are reportedly up 12% and 7% YTD respectively. Those latter cutoffs, share classes and net/gross bases were not established. Dispersion within a manager is the point; the logo is not the portfolio. Financial Times

The useful deadline is 10 a.m. today. Reminder: the artist/local presale opens for Animal Collective playing Feels, October 22 at Knockdown Center, Queens. The original quartet will perform the album plus other material, reviving old loops and samples for the occasion. Presale eligibility/code, price and selectable seats remain unverified; public sale follows tomorrow at 10 a.m. ET. Band’s label announcement

DeepSeek has a new model this morning—and a useful thing to inspect. V4.1 Flash launched today. The company’s capability and efficiency claims need independent testing; its accompanying engineering releases offer a more concrete starting point. The interesting kernel is below. Reuters

Tonight’s NFL game is on Netflix, not Prime. 49ers–Rams, 8:35 p.m. ET, from Melbourne, is included with a US Netflix subscription. It is Friday morning there; Thursday-night streaming rights have become sufficiently elaborate without adding a date line. 49ers schedule, US viewing details

Seattle won; the injury news may matter longer. The Seahawks beat New England 13–10 last night. Sam Darnold left with a hip injury, bringing in Drew Lock; Drake Maye threw three fourth-quarter interceptions. That closes yesterday’s conditional Patriots-moneyline idea as a losing selection—not evidence that any wager was placed. AP

SIX’s September 8 Market Signal launch bundles real-time and historical data through an API, with best bids and offers across SIX, BME and Aquis’s 16 European markets. The consequential sentence is about rights: SIX explicitly says users are licensed to train trading models and AI agents on the data. Institutions can access the offering now; the retail rollout begins in Switzerland, with EU and UK expansion planned. Official announcement

For a quant organization, the attractive proposition is fewer negotiations between “we can retrieve this” and “we may use it in the experiment.” A research agent that can query historical observations, construct features and leave an auditable record is more useful than another chat interface over a price chart. Clear training rights could make that workflow easier to approve. That is my inference—not proof that a particular institution’s intended use is covered by the final contract.

There are two important limits. This is group-venue coverage, not a consolidated European best-price record, and BBO is not depth. A strategy evaluated against this universe could mistake a coverage gap for a trading opportunity. Nor does an accessible API establish suitability for a latency-sensitive production path: the launch materials do not settle the price, latency SLA or your redistribution requirements. Product scope, The Trade

Worth a look for research-data procurement and agent experiments. Not grounds to retire a direct feed. The distinction is rather more expensive to discover after deployment.

Yesterday’s ION–Coinbase announcement concerns event-contract processing and clearing on Kalshi, using ION’s XTP infrastructure. The reported integration supports real-time contract creation, large numbers of accounts and round-the-clock processing. This is an incremental infrastructure development: XTP added event-contract support in April, and the broader three-party collaboration dates to December 2025. It is not a newly invented market. The Trade, September 9

The competitive implication is distribution. An FCM already using familiar back-office infrastructure faces a different integration problem from one building a separate event-contract stack. Lower connection costs could bring more intermediaries and eventually more flow; the announcement itself does not establish that either has arrived.

For a trading or risk team, the harder work remains contract semantics. Two similarly named markets can differ in resolution source, cancellation treatment and dispute process. Those differences belong in instrument identity and exposure aggregation, not a footnote attached to the ticker.

Watch actual intermediary adoption and usable liquidity next. Prediction markets can acquire institutional plumbing before they acquire institutional depth.

Alongside the model news, DeepSelect v1.0.0 appeared today: open-source GPU top-k kernels for DeepSeek sparse attention and sampling. The vendor reports 2–20× speedups over stock torch.topk in its tested workloads. That is a kernel comparison, not a 2–20× improvement in serving an entire model. Repository and benchmark instructions

The constraints make this worth reading rather than merely retweeting. The attention path uses bfloat16, the sampling path float32; supported k is at most 4,096. Layout and alignment matter, and outputs may be non-contiguous. One particularly consequential wrinkle: NaN checking normally traps, but rows whose length is no greater than k are not checked.

My interest is practical: if profiling shows top-k selection is material in a research-serving workload, this supplies a bounded optimization to test against your actual shapes, GPU and correctness suite. The repository includes a performance-only test mode. I have not run it.

Otherwise, file it away. A twentyfold improvement to something that barely appears in the profile is an excellent result for the benchmark and a modest one for the user.

A fresh September 9 review by Nadia Chaudhury gives a familiar restaurant a useful second look: she singles out the seafood and reports a $45 happy-hour seafood tower. At the original 55 Bond Street location, the restaurant confirms happy hour runs noon–5 p.m. daily. That makes a late lunch potentially more appealing than automatically pursuing the prime dinner slot. The tower price is the review’s report, not a live checkout quote. Eater, official location and hours

For a shared meal, the suggested order is coconut crab curry, whole steamed branzino with Thai herbs and lime, and som tum corn salad. The current menu supplies a substantive seafood path without making dairy or eggs the centerpiece; coconut is doing the creamy work in the curry. Current menu

Two easy mistakes to avoid: Prawn Karee contains soft-scrambled egg; Crab Awoonsen includes pork fat. Neither is the obvious choice its seafood name suggests. Confirm any ingredient substitutions when ordering.

This is the lively, strongly flavored option for friends—not the discreet room for a quiet conversation. Reservations were not verified this morning.

Rybakina has already won something before the semifinal. Her 3–6, 6–1, 6–4 victory over Zheng Qinwen secured the world No. 1 ranking in the next rankings release. Gauff is therefore meeting the incoming No. 1, not simply another survivor of a long quarterfinal. The Guardian

The other women’s semifinal is Sabalenka–Pegula today. Sabalenka leads their rivalry 9–4, but Pegula has won two of the last three: a more useful complication than treating the lifetime record as destiny. Reuters preview

For Friday, the men’s draw is now complete: Shelton–Tiafoe and Zverev–Khachanov. Zverev beat Van de Zandschulp 6–2, 7–5, 6–1 last night and is the only remaining major champion. Alcaraz’s exit has opened the tournament; it has not made the American semifinal the final. Reuters

BETTING — PASS today. Tennis Abstract’s current draw forecast makes Rybakina a modest 53.7% favorite over Gauff; its separate Sabalenka–Pegula estimate is 64.1%–35.9%. These are Elo-based model estimates, not prices or established edges. The exact input cutoff was not disclosed, and recovery after yesterday’s matches is a meaningful uncertainty. Forecast, method

I could not verify timestamped, executable FanDuel/DraftKings quotes or an eligible boost against those forecasts. No recommended side or invented entry price. Gauff’s escape is a reason to watch; it is not, by itself, a reason to pay more for her.

Released yesterday, September 9. Start with the official track/video, not an album-length commitment.

Pitchfork’s first track review describes a densely layered, unhurried song that refines the band’s existing language rather than trying to escape it. The appeal is an adjacent route from Radiohead/LCD-scale immersion toward expansive guitar music, with less nocturnal menace than Portishead. It is a change of light, not a claim that these bands sound alike. First criticism

The charming origin story: Adam Granduciel says he wrote it in roughly ten minutes between coffee and the school drop-off. A useful rebuke to the idea that every creative act requires a monastery and an equipment grant. The sonic description above is the critic’s, not a claim that I have listened. Release reporting

Netflix US subscription; released today. One feature, not a new season. French original audio and English subtitles are available; the public listing did not expose a reliable feature runtime. Netflix, release page

Five years after ASK closed, Andréa is directing her first film when her lead actor drops out, drawing the old team back together. My choice tonight is this livelier register: comic intelligence, vanity and personalities colliding, rather than another solemn documentary that asks to be admired at the end of a long day.

The early disagreement is worth knowing. The Guardian’s Leslie Felperin finds the reunion funny and well judged. Review

The FT gives it two stars, arguing that reassembling the ensemble does not restore the agency machinery that made the series work. That is a substantive objection: celebrity cameos and returning characters are ingredients, not necessarily a comic engine. Financial Times

My recommendation is for the wit and company, with that structural caveat—not a declaration that the sequel has met universal approval. If you have never watched the series, this reunion is a less natural entry point.
