Verify deadlines on source links before relying on them. Values the dataset couldn't confirm are flagged in sienna; machine-parseable dates and costs are rendered in green.
Slack
Model-agnostic agent build (Claude is fine as the brain) with real cash and a fast 9-day window — squarely in your wheelhouse. The single catch: you must build on the Slack platform, so budget a day for Slack's app/agent scaffolding before the AI work starts.
Innovation Hacks
Open-ended agentic AI, solo-friendly, IST deadline and Claude-allowed — perfect thematic fit and easy to enter. The catch: prizes are certificates only, no cash or credits, so treat it as portfolio/credential filler rather than a payday.
Kaya AI & WnCC (IIT Mumbai)
India-based, real rupee cash, model-agnostic AI with an Open Innovation track that lets you sidestep the physical-AI/supply-chain angle. Strong fit; the catch is the physical-AI framing may favor hardware-adjacent teams, so lean hard into the open track and confirm certificate status on site.
IEEE KCE Student Branch CIS Chapter
India IEEE event, Open Innovation track keeps it model-agnostic and solo-doable, with rupee cash plus a certificate. The catch: small prize pool and student/civic framing, so it's a fast, low-stakes win-odds play rather than a big payout.
Devpost
Solo-friendly, model-agnostic, low/no-code social-good build with a comfortable runway. Catch: token cash ($300) and a beginner framing, so it's a light portfolio piece rather than a serious prize target.
Aethra
Open-ended solo-friendly AI build with a large headline prize pool, but it's all non-cash sponsor swag/credits. Biggest catch: the July 5 deadline is nearly here, so only jump in with an existing demo.
Big cash pool and solo-doable, but the catch is it's a game built on Reddit's Devvit/Phaser platform — off-profile for an AI/full-stack vibe-coder and Claude adds little here. Only worth it if a game idea genuinely excites you.
Student Council
Wide-open themes, solo-friendly and model-agnostic with a generous deadline. Catch: a single non-cash prize and vague organizer, so it's low-value — a filler entry at best.
One-day web build that suits your speed, but the disqualifying catch for this profile: it mandates the Gemini API, not Claude. Only enter if you're happy to swap models for the day; prizes are swag/credits.
FlowZint
India-hosted on Unstop, rupee cash, an Open Innovation track, and chatbot themes that map directly to Claude-powered agents — excellent fit for a solo AI builder. The catch: much of the prize pool is FlowZint platform credits, and you'll likely need to build within/around their product, so check the platform constraints before committing.
Anthropic & Gladstone Institutes via Cerebral Valley
This is a Claude-native event — your exact stack — and even applying nets top-500 folks Max access plus API credits, which is high-value to you specifically. Two catches: apply by July 5, and the domain is life-sciences/bio, so you'll need a research-flavored idea (RAG-over-literature is the accessible on-ramp). Prizes are credits, not cash.
Pixel Forge
Model-agnostic, solo-friendly AI/web sprint with a certificate and near-guaranteed participant perks. Catch: prizes are software licenses and domains, no cash, so it's a credential-and-swag play.
CodeStorm (via Devfolio)
Devfolio web-app sprint that fits your full-stack speed and offers a certificate, solo-friendly and Claude-allowed. Catches: prize details are unlisted (verify on site) and it's a lower-profile event, so treat it as a certificate/portfolio entry.
Kaggle (with OpenAI, Google, IEEE)
Solo-allowed with strong cash and an agent-security theme adjacent to your work. Catch: this is a Kaggle ML competition (leaderboard/notebook grind), not a ship-a-demo hackathon — it rewards adversarial ML depth over fast vibe-coding, so it's off your usual mode.
Google + Kaggle
Literally a 'vibe coding' AI-agents capstone — on-theme for you and yields a certificate. Two catches: the July 6 deadline is imminent, and it's a course capstone (no cash, likely Google/Gemini-tooling-oriented), so it's a credential rather than a competition.
KeeperHub (on DoraHacks)
AI-agent theme overlaps your skills, but the catch is the onchain/Ethereum requirement — you'd need Web3/smart-contract plumbing that's off your stack, for a modest bounty pool. Skip unless you want a crypto detour.
Devpost
Broad AI theme, model-agnostic and solo-ok. Two catches: the deadline is imminent (July 5), and prizes are credits/badges rather than cash — only worth it if you already have something near-shippable.
Aethra

Qwen (Alibaba Cloud)
Strong cash and agent themes that fit your skills, but the profile catch is real: it's built around Qwen (a competing model), so Claude is off the table here. Only enter if you'll build on Qwen; deadline is also near (July 9).
Kaya AI & WnCC (IIT Mumbai)
Fit India-based, real rupee cash, model-agnostic AI with an Open Innovation track that lets you sidestep the physical-AI/supply-chain angle. Strong fit; the catch is the physical-AI framing may favor hardware-adjacent teams, so lean hard into the open track and confirm certificate status on site.

Fit Real cash, a beginner-friendly agent track, and an open 'Unicorn' track keep it flexible.

Fit Perfect on-profile build week: fully online, free, explicitly AI-agents themed, open globally, and you can use the Claude API freely solo. It's swag/portfolio rather than cash, so treat it as a fast, high-signal demo to ship and reuse.
Fit Enormous cash pool, solo-allowed, long runway, and themes (financial access, small business, education) that suit an India-market builder. The catch: it mandates the Gemini API, not Claude — so you'd swap models. Given the $2M pool and your speed, it's still worth a serious swing despite that.
